Description

Technical Field

[0001] The present application relates to the technical field of composite plate manufacturing, and in particular to a composite plate centrifugal manufacturing device and a manufacturing process thereof. Background Art

[0002] In actual working conditions, multiple material properties are often required at the same time to ensure complex process purposes. For example, in a mining working environment, excavation components must have both toughness and strength as well as wear resistance and corrosion resistance; boiler pipes must not only withstand high temperatures, but also high pressures and corrosion. These requirements are often impossible to meet with a single material. Therefore, composite materials with multiple properties are born.

[0003] At present, composite steel plates are mainly produced by surface treatment + vacuum welding + hot rolling, or by explosive synthesis. However, this technology is all through solid-solid composite, the bonding surface strength of two different metals is limited, and the processing cost is high. In this regard, a method for producing composite plates using a centrifugal casting process is proposed, which uses centrifugal casting to manufacture composite plates.

[0004] When the die speed reaches the standard, the molten metal is poured, and the second molten metal is poured through the flow channel immediately after the first metal is completely solidified. When the centrifuge speed reaches zero, it is cooled naturally, the tube billet is taken out, the composite tube billet is opened along the axis, and the tube billet is heated by the heating furnace and rolled to form a composite plate. However, this method produces an integral tube billet, and the tube billet needs to be cut along the axis after forming, which not only reduces efficiency but also increases cost.

[0046] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0047] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0048] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "on" or "below" a second feature, etc., or the like, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0050] It is understandable that when the composite plate is produced by the centrifugal casting process, the molten metal is cast when the mold speed reaches the standard, and the second molten metal is immediately poured through the flow channel after the first metal is completely solidified. When the centrifuge speed is zero, it is naturally cooled, the tube billet is taken out, the composite tube billet is opened along the axis, and the heating furnace heats the tube billet and rolls it to form a composite plate. However, this method produces an integral tube billet, and the tube billet needs to be cut along the axis after forming, which not only reduces efficiency but also increases cost.

[0051] Referring to Figures 1 and 2, the present application provides a novel composite plate centrifugal manufacturing device 100. Figure 1 is a front view of a composite plate centrifugal manufacturing device 100 according to an embodiment of the present application, and Figure 2 is a side view of the composite plate centrifugal manufacturing device 100 shown in Figure 1. The composite plate centrifugal manufacturing device 100 can manufacture a metal composite plate by a centrifugal method, and the composite plate is made of at least two metal materials.

[0052] The composite plate centrifugal manufacturing equipment 100 can cast two or more molten metals to manufacture a composite tube blank 200. When the composite tube blank 200 leaves the composite plate centrifugal manufacturing equipment 100, the composite tube blank 200 can be automatically separated by the crushing and separation component 112, and there is no need to perform axial cutting on the composite tube blank 200, which greatly improves production efficiency and reduces production costs.

[0053] Here, a brief introduction to the technical terms is given. After at least two types of molten metals are successively cast into the centrifugal casting chamber 1113 of the centrifugal manufacturing device 100 for composite plates, the at least two molten metals solidify layer by layer to form a tubular composite tube blank 200. After the tubular composite tube blank 200 is separated from the centrifugal casting chamber 1113, the composite tube blank 200 is separated into two parts, and the two parts of the composite tube blank 200 have the same structure. Each part of the composite tube blank 200 is flattened to form a composite plate blank, and the composite plate blank is heated to form a composite plate.

[0054] The specific structure of a composite plate centrifugal manufacturing device 100 according to an embodiment is introduced below.

[0055] Referring to FIGS. 1 to 4 , in one embodiment, the composite plate centrifugal manufacturing device 100 includes a casting assembly 110 and a driving assembly 120. The casting assembly 110 includes a casting mold 111 and at least one partition member 112, the casting mold 111 having a centrifugal casting chamber 1113, and at least one partition member 112 protruding from the inner wall of the centrifugal casting chamber 1113. The driving assembly 120 is disposed around the circumference of the casting mold 111 and abuts against the casting mold 111, and the driving assembly 120 drives the casting mold 111 to rotate. FIG. 3 is a partial enlarged view of the composite plate centrifugal manufacturing device 100 shown in FIG. 1 at A, and FIG. 4 is a partial schematic view of the composite plate centrifugal manufacturing device 100 shown in FIG. 2 .

[0056] The casting assembly 110 is the main structure for casting the composite tube blank 200. The casting assembly 110 has a hollow centrifugal casting chamber 1113, into which molten metal is injected. The driving assembly 120 is a power source for driving the casting assembly 110 to rotate. The driving assembly 120 is arranged on the periphery of the casting assembly 110 and abuts against the casting assembly 110. When the driving assembly 120 is working, it can drive the casting assembly 110 to rotate, and then the molten metal can make centrifugal motion in the centrifugal casting chamber 1113 to fill the inner wall of the centrifugal casting chamber 1113 and solidify to form the composite tube blank 200.

[0057] Specifically, the casting assembly 110 includes a casting mold 111 and a partition component 112. The casting mold 111 is a main component for casting the composite tube blank 200, and the partition component 112 is a component for separating the composite tube blank 200 into two parts. The casting mold 111 is arranged in an annular shape, and at least one partition component 112 is arranged on the inner wall of the centrifugal casting chamber 1113 and protrudes from the inner wall of the centrifugal casting chamber 1113. The height of the inner wall portion of the partition component 112 protruding from the centrifugal casting chamber 1113 is greater than the thickness of the composite tube blank in the radial direction, that is, the partition component 112 passes through the composite tube blank, so that after the partition component 112 is broken, the composite tube blank can be automatically separated.

[0058] When pouring the molten metal into the centrifugal casting chamber 1113, the molten metal can rotate with the casting mold 111, so that the molten metal performs centrifugal motion in the centrifugal casting chamber 1113, and then the molten metal can cover the inner wall of the centrifugal casting chamber 1113 until the molten metal solidifies. In this process, the partition member 112 can contact with the molten metal and will not affect the flow of the molten metal in the centrifugal casting chamber 1113.

[0059] After the molten metal solidifies, the partitioning component 112 can separate the solidified molten metal, so that the composite tube blank 200 forms a discontinuous annular structure, and the partitioning component 112 and the composite tube blank 200 form an integral body. When the composite tube blank 200 is pushed out of the centrifugal casting chamber 113, since the partitioning component 112 and the composite tube blank 200 form an integral body, the partitioning component 112 can be pushed out of the centrifugal casting chamber 113 synchronously when the composite tube blank 200 is pushed out, and the composite tube blank 200 can be automatically separated by breaking the partitioning component 112, without cutting the composite tube blank 200. It should be noted that since the partitioning component 112 is made of refractory material or ceramic material and has the characteristic of being fragile, the partitioning component 112 may be partially or completely broken when pushed out, and the unbroken part can be further broken manually.

[0060] In this embodiment, there are multiple partition members 112, and the multiple partition members 112 are circumferentially arranged on the inner wall of the centrifugal casting chamber 1113. After the multiple partition members 112 are broken, the composite tube blank 200 can be automatically separated into multiple parts, and then the multiple parts of the tube blank 200 are flattened, heat-matched, and pressed into composite plates.

[0061] Optionally, the plurality of partition members 112 may be evenly distributed or unevenly distributed in the centrifugal casting chamber 113 , and the distribution is set according to the required width of the composite plate, which will not be described in detail here.

[0062] Of course, in other embodiments of the present application, the number of the partition member 112 may be one. After the partition member 112 is broken, the composite tube blank 200 has an opening, and the composite tube blank 200 is flattened, heat-matched, and then pressed into an integral composite plate.

[0063] When the composite plate centrifugal manufacturing device 100 of the present application is used to manufacture the composite plate, a partition member 112 is provided in the centrifugal casting chamber 1113 of the casting mold 111, so that the partition member 112 protrudes from the inner wall of the centrifugal casting chamber 1113. Then, at least two molten metals are successively injected into the centrifugal casting chamber 1113, and the at least two molten metals solidify layer by layer to form a composite tube blank 200. Subsequently, the composite tube blank 200 is pushed out of the centrifugal casting chamber 1113, and the composite tube blank 200 is automatically separated by breaking the partition member 112, and then the two parts of the composite tube blank 200 are respectively flattened, heated, and pressed into a composite plate.

[0064] In the centrifugal manufacturing equipment 100 of the composite plate of the above embodiment, a partitioning component 112 is provided in the centrifugal casting chamber 1113. When the molten metal is poured into the centrifugal casting chamber 1113, the partitioning component 112 is located in the molten metal during the centrifugal rotation of the molten metal in the centrifugal casting chamber 1113. When the molten metal solidifies to form a composite tube blank 200, the partitioning component 112 can separate the composite tube blank 200 in the radial direction. In this way, after the composite tube blank 200 is pushed out of the centrifugal casting chamber 1113, the partitioning component 112 can separate the composite tube blank 200 by breaking the partitioning component 112, and there is no need to cut the composite tube blank 200 axially, which greatly improves production efficiency and reduces production costs.

[0065] 1 to 4 , in one embodiment, the casting mold 111 includes a plurality of half molds, which surround a centrifugal casting chamber 1113 , and at least one partition member 112 is disposed between adjacent half molds and protrudes from the inner wall of the centrifugal casting chamber 1113 .

[0066] That is, the casting mold 111 is a split mold, and a plurality of half molds are arranged and spliced ​​along the circumference to form a whole casting mold 111. At least one partition member 112 is arranged between adjacent half molds and protrudes from the inner wall of the centrifugal casting chamber 1113, so that the partition member 112 can separate the composite tube blank 200, which is convenient for the later separation of the composite tube blank 200. It should be noted that the fixed connection between the half molds of the split mold is a prior art means, which will not be described in detail here.

[0067] In one embodiment, a partition member 112 is disposed between any adjacent half molds. Of course, in other embodiments of the present application, a partition member may also be disposed between at least some of the adjacent half molds. In one embodiment, the half molds are disposed in an arc shape, and the radius of each half mold is the same or different. In this way, the radius of the half mold can be selected according to the width of the composite board.

[0068] 1 to 4 , in this embodiment, there are two half molds, namely a first half mold 1111 and a second half mold 1112. The first half mold 1111 and the second half mold 1112 surround a centrifugal casting chamber 1113, and the partition member 112 is disposed between the first half mold 1111 and the second half mold 1112 and protrudes from the inner wall of the centrifugal casting chamber 1113.

[0069] Referring to Figures 1 to 4, specifically, the casting mold 111 includes a first half mold 1111 and a second half mold 1112. The first half mold 1111 and the second half mold 1112 are both semicircular structures. After the first half mold 1111 and the second half mold 1112 are matched and connected, the first half mold 1111 and the second half mold 1112 form a complete tubular casting mold 111.

[0070] That is, the casting mold 111 is a two-piece structure, and the casting mold 111 is cut from the central axis to form two symmetrical parts, namely the first half mold 1111 and the second half mold 1112. After the first half mold 1111 and the second half mold 1112 are matched, the inner wall of the first half mold 1111 and the inner wall of the second half mold 1112 are arranged to form a complete centrifugal casting chamber 1113. The first half mold 1111 and the second half mold 1112 extend along the axial direction of the tubular casting mold 111, and the radial direction is the radius direction of the casting mold 111.

[0071] The partition member 112 is disposed between the first half mold 1111 and the second half mold 1112, and extends radially into the casting mold 111. That is, there are two partition members 112, and the partition members 112 are disposed at two connecting points between the first half mold 1111 and the second half mold 1112, and the partition members 112 protrude from the inner wall of the centrifugal casting chamber 1113 and extend axially. In other words, the partition members 112 are symmetrically disposed between the first half mold 1111 and the second half mold 1112, and are located in the centrifugal casting chamber 1113.

[0072] When the composite plate centrifugal manufacturing device 100 of the present application is used to manufacture the composite plate, the first half mold 1111 and the second half mold 1112 of the casting mold 111 are enclosed to form a centrifugal casting chamber 1113, and a partition component 112 is arranged between the first half mold 1111 and the second half mold 1112, so that the partition component 112 protrudes from the inner wall of the centrifugal casting chamber 1113. Then, at least two molten metals are successively injected into the centrifugal casting chamber 1113, and the at least two molten metals solidify layer by layer to form a composite tube blank 200. The composite tube blank 200 is pushed out of the centrifugal casting chamber 1113, and after the partition component 112 is broken, the composite tube blank 200 is automatically separated into two parts, and then the two parts of the composite tube blank 200 are respectively flattened and heated and pressed into a composite plate.

[0073] Of course, in other embodiments of the present application, the number of half molds can be three, four or even more, which can be set according to actual usage requirements. The principle is essentially the same as the principle of having two half molds, and will not be repeated here. In addition, when describing the structure of the composite plate centrifugal manufacturing equipment 100 later, only the casting mold 111 including the first half mold 1111 and the second half mold 1112 is used as an example for description.

[0074] 1 and 3, in one embodiment, the partition member 112 includes a mounting portion 1121 and a separation tip 1122, the separation tip 1122 is disposed on the mounting portion 1121, the mounting portion 1121 is mounted between adjacent half molds, and the separation tip 1122 is located in the centrifugal casting chamber 1113. Specifically, the mounting portion 1121 is mounted between the first half mold 1111 and the second half mold 1112. The separation tip 1122 is disposed at one end of the mounting portion 1121, the mounting portion 1121 is clamped and fixed between the first half mold 1111 and the second half mold 1112, and the separation tip 1122 is exposed in the centrifugal casting chamber 1113 surrounded by the first half mold 1111 and the second half mold 1112.

[0075] The end of the separation tip 1122 is pointed, as shown in Figures 1 and 3. In this way, the separation component 112 contacts the molten metal through the separation tip 1122, reducing the contact area between the separation tip 1122 and the molten metal, and at the same time, it can also reduce the situation where the separation tip 1122 is sludged, avoiding the presence of a gap in the contact portion between the composite tube blank 200 and the separation tip 1122 due to the sludge, thereby ensuring the molding quality of the composite tube blank 200.

[0076] In one embodiment, the mounting portion 1121 and the separation tip 1122 are an integral structure. That is, the mounting portion 1121 and the separation tip 1122 are integrally formed, so that the structural strength of the partition member 112 can be ensured, so that the partition member 112 can accurately separate the composite tube blank 200.

[0077] In one embodiment, the partition member 112 is made of a refractory material or a ceramic material. Thus, the partition member 112 has the characteristics of being resistant to high temperatures and being fragile. When the casting mold 111 is heated and molten metal is injected into the centrifugal casting chamber 1113, the partition member 112 will not be melted by the heat, so as to accurately separate the composite tube blank 200. When the composite tube blank 200 is pushed out of the casting mold 111, the partition member 112 made of a refractory material or a ceramic material can be broken, so that the composite tube blank 200 is automatically separated into two parts.

[0078] 1 and 3, in one embodiment, the half mold has a first groove body, and the adjacent half mold has a second groove body, and the first groove body and the second groove body are surrounded by a mounting groove 1114 to accommodate the mounting portion 1121, and the shape of the mounting groove 1114 is adapted to the shape of the mounting portion 1121. Specifically, the first half mold 1111 has a first groove body, and the second half mold 1112 has a second groove body.

[0079] The end surface of the first half mold 1111 facing the second half mold 1112 has a first groove body, and the end surface of the second half mold 1112 facing the first half mold 1111 has a first groove body, and the positions of the first groove body and the second groove body correspond. After the first half mold 1111 and the second half mold 1112 are matched, the first groove body and the second groove body are connected to form a mounting groove 1114, and the mounting portion 1121 of the partition component 112 is located in the mounting groove 1114, so that the partition component 112 is fixedly installed between the first groove body and the second groove body.

[0080] Moreover, the shape of the mounting groove 1114 is consistent with the shape of the mounting portion 1121. In this way, the mounting portion 1121 of the partition member 112 can be accurately installed in the mounting groove 1114, and the movement of the partition member 112 can be reduced as much as possible to ensure the molding quality of the composite tube blank 200. Optionally, the shape of the separation tip 1122 is an isosceles triangle, and the shape of the mounting portion 1121 is not limited in principle, as long as the mounting portion 1121 can be installed in the mounting groove 1114 between the first half mold 1111 and the second half mold 1112.

[0081] For example, the longitudinal section of the partition member 112 is an isosceles triangle, the separation tip 1122 is an isosceles triangle, the longitudinal section of the mounting portion 1121 is an isosceles trapezoid, and the corresponding mounting groove 1114 is also an isosceles trapezoid. Of course, in other embodiments of the present application, the longitudinal section of the mounting portion 1121 may also be a rectangle, T-shaped, etc.

[0082] When assembling the casting assembly 110, the first half mold 1111 and the second half mold 1112 are spliced ​​and fixed to form a centrifugal casting chamber 1113. At this time, the first half mold 1111 and the second half mold 1112 are surrounded by a mounting groove 1114. The mounting portion 1121 of the separation component is axially mounted into the mounting groove 1114 to complete the assembly of the casting assembly 110.

[0083] 1 and 3 , in one embodiment, the separation tip 1122 can penetrate the composite tube blank 200, and the separation tip 1122 protrudes from the inner wall of the composite tube blank 200. After the composite tube blank 200 is prepared by the casting mold 111, the end of the partition member 112 can penetrate the inner wall of the composite tube blank 200.

[0084] In this way, the partition component 112 can effectively separate the composite tube blank 200 into two parts. When the partition component 112 is broken, the two parts of the composite tube blank 200 have no connected parts, and the two parts of the composite tube blank 200 can be flattened and heat-treated separately.

[0085] Referring to FIG. 1 and FIG. 3 , in one embodiment, after the separation tip 1122 penetrates the composite tube blank 200, the radial dimension of the separation tip 1122 exposed from the inner wall of the composite tube blank 200 is greater than 30% of the radial thickness of the composite tube blank 200. In this way, the partition component 112 can effectively separate the composite tube blank 200 into two parts, which is convenient for the subsequent separation operation of the composite tube blank 200. In one embodiment, the height of the mounting portion 1121 is greater than 30% of the radial thickness of the composite tube blank 200, so that the mounting portion 1121 can be more easily broken during the process of the composite tube blank 200 being pushed out.

[0086] 1 and 2, in one embodiment, the composite plate centrifugal manufacturing device 100 further includes a horizontal moving assembly 130, and a plurality of half molds are separately arranged in the horizontal moving assembly 130, and move with the horizontal moving assembly 130, so that the plurality of half molds are close to each other or away from each other. Specifically, the first half mold 1111 and the second half mold 1112 are separately arranged in the horizontal moving assembly 130, and move with the horizontal moving assembly 130, so that the first half mold 1111 and the second half mold 1112 are close to each other or away from each other.

[0087] The horizontal moving assembly 130 is disposed on the ground or an operating table, and the casting mold 111 is disposed in the horizontal moving assembly 130 . The horizontal moving assembly 130 can enable the first half mold 1111 and the second half mold 1112 to move closer to or farther from each other, so as to facilitate the casting of the composite tube blank 200 in the later stage.

[0088] Typically, the size of the composite tube blank 200 is relatively large, and accordingly, the sizes of the first half mold 1111 and the second half mold 1112 are also relatively large. The horizontal moving assembly 130 can be used to move the first half mold 1111 and the second half mold 1112, and can also position the first half mold 1111 and the second half mold 1112, thereby avoiding positional shifting of the first half mold 1111 and the second half mold 1112, and thus ensuring the casting quality of the composite tube blank 200.

[0089] When manufacturing the composite tube 200, the horizontal moving assembly 130 drives the first half mold 1111 and the second half mold 1112 to move closer to each other to enclose the centrifugal casting chamber 1113. After the casting is completed, the composite tube 200 is pushed out of the centrifugal casting chamber 1113, and the horizontal moving assembly 130 can drive the first half mold 1111 and the second half mold 1112 to move away from each other.

[0090] 1 and 2 , in one embodiment, the horizontal moving assembly 130 includes a first slide 131, a second slide 132, a first bracket 133 and a second bracket 134. The first slide 131 and the second slide 132 are arranged at intervals in the height direction. The first bracket 133 and the second bracket 134 are slidably disposed between the first slide 131 and the second slide 132. Part of the half mold is disposed on the first bracket 133, and part of the half mold is disposed on the second bracket 134. Specifically, the first half mold 1111 is disposed on the first bracket 133, and the second half mold 1112 is disposed on the second bracket 134.

[0091] The first slideway 131 and the second slideway 132 are arranged opposite to each other, and the first slideway 131 is located on the ground or the operating table, and the second slideway 132 is located above the first slideway 131. An installation space is enclosed between the first slideway 131 and the second slideway 132, and the first bracket 133 and the second bracket 134 are located in the installation space and can be slidably arranged on the first slideway 131 and the second slideway 132.

[0092] The first half mold 1111 is rotatably disposed on the first bracket 133, and the second half mold 1112 is rotatably disposed on the second bracket 134. The first half mold 1111 is opposite to the second half mold 1112. When the first bracket 133 and the second bracket 134 slide along the first slideway 131 and the second slideway 132, the first half mold 1111 and the second half mold 1112 can be moved closer to or farther away from each other.

[0093] Moreover, after the first half mold 1111 and the second half mold 1112 are arranged to form the centrifugal casting chamber 1113, the first half mold 1111 and the second half mold 1112 can rotate relative to the first bracket 133 and the second bracket 134 around the central axis of the centrifugal casting chamber 1113. Optionally, the first bracket 133 and the second bracket 134 can be controlled to move closer to or farther from each other in the horizontal direction by a motor or the like.

[0094] Optionally, the number of the first slideway 131 and the second slideway 132 are both two, and both are in the form of a slide rail-like structure, the two first slideways 131 are spaced apart on the horizontal plane, the two second slideways 132 are spaced apart on the horizontal plane, and are arranged corresponding to the two first slideways 131, and the first bracket 133 and the second bracket 134 are guided and limited by the two first slideways 131 and the two second slideways 132. Of course, in other embodiments of the present application, the first slideway 131 and the second slideway 132 may also be in the form of a flat plate, etc.

[0095] Referring to FIG. 1 and FIG. 2 , in one embodiment, the driving assembly 120 includes a driving member, a driving wheel 121 and a plurality of driven wheels 122. The output end of the driving member is provided with the driving wheel 121, which is rotatably disposed on the first bracket 133 and abuts against the outer wall of one half mold. The plurality of driven wheels 122 are rotatably disposed on the first bracket 133 and the second bracket 134, respectively, and abut against the outer walls of the plurality of half molds. Specifically, the driving wheel 121 abuts against the outer wall of the first half mold 1111, and the plurality of driven wheels 122 abut against the outer walls of the first half mold 1111 and the second half mold 1112, respectively.

[0096] The driving member is the power source of the driving wheel 121. The driving wheel 121 is arranged on the first bracket 133. The plurality of driven wheels 122 are respectively arranged on the first bracket 133 and the second bracket 134. The driving wheel 121 and the plurality of driven wheels 122 simultaneously abut against the outer walls of the first half mold 1111 and the second half mold 1112. When the driving member drives the driving wheel 121 to rotate, the driving wheel 121 can drive the first half mold 1111 and the second half mold 1112 to rotate synchronously, and then the first half mold 1111 and the second half mold 1112 can drive the plurality of driven wheels 122 to rotate synchronously.

[0097] The cooperation between the driving wheel 121 and multiple driven wheels 122 can ensure the stability of the rotation of the casting mold 111, and play a role in reinforcement and stability. At the same time, the driving wheel 121 can drive the casting mold 111 to rotate, and the multiple driven wheels 122 further assist in clamping the casting mold 111 to prevent the casting mold 111 from shifting during the rotation process, thereby ensuring the molding quality of the composite tube blank 200.

[0098] Optionally, the driving member is a structure in which a motor cooperates with a pulley to drive the driving wheel 121 to rotate. Optionally, there are three driven wheels 122, one of which is disposed on the first bracket 133, and the other two driven wheels 122 are disposed on the second bracket 134, and the driving wheel 121 and the plurality of driven wheels 122 are symmetrically disposed.

[0099] In other embodiments of the present application, the number of driven wheels 122 can be greater, and the positions of the first half mold 1111 and the second half mold 1112 can be limited by more driven wheels 122, and the stability of the rotation of the casting mold 111 can be ensured; of course, the driving wheel 121 can also be set on the second bracket 134, and multiple driven wheels 122 are respectively set on the first bracket 133 and the second bracket 134.

[0100] 1 and 2 , in one embodiment, at least part of the driven wheel 122 moves in the vertical direction relative to the first bracket 133 and / or the second bracket 134. The driven wheel 122 can adjust its position in the vertical direction, thereby adjusting the distance between the driven wheel 122 and the first half mold 1111 and the second half mold 1112.

[0101] That is to say, the driven wheel 122 can be movably arranged, so that the space enclosed by the driving wheel 121 and multiple driven wheels 122 has different sizes to adapt to casting molds 111 of different diameters, so that composite tube blanks 200 of different specifications and models can be produced, making the specifications of the composite tube blanks 200 more flexible and diversified.

[0102] Optionally, the vertical position of some driven wheels 122 is adjustable. The position of some driven wheels 122 can be adjusted in the vertical direction. Of course, in other embodiments of the present application, the position of all driven wheels 122 can be adjusted in the vertical direction.

[0103] In the composite plate centrifugal manufacturing equipment 100 of the present application, the first bracket 133 and the second bracket 134 can move horizontally between the first slide 131 and the second slide 132, and can be locked in any required position. At the same time, multiple driven wheels 122 can adjust the vertical position on the first bracket 133 and the second bracket 134. In this way, the driving wheel 121 and the multiple driven wheels 122 can achieve four points of any diameter to be cocircular, meeting the reinforcement and stability of casting molds 111 with different diameters.

[0104] Optionally, the driving assembly 120 further includes a fastener, which rotatably fixes the driven wheel 122 to the first bracket 133 and the second bracket 134. When the fastener is loosened, the vertical position of the driven wheel 122 relative to the first bracket 133 and the second bracket 134 can be adjusted. After the fastener is tightened, the position of the driven wheel 122 is fixed, and at this time, the driven wheel 122 can abut against the outer walls of the first half mold 1111 and the second half mold 1112 of the required size.

[0105] 1 , 2 and 4 , in one embodiment, the composite plate centrifugal manufacturing apparatus 100 further includes a vertical moving member 140 , which is disposed between the first slide 131 and the second slide 132 to adjust the distance between the first slide 131 and the second slide 132 .

[0106] The bottom of the vertical moving member 140 is disposed on the first slideway 131, and the top of the vertical moving member 140 abuts against the second slideway 132. The vertical moving member 140 can output a movement in the vertical direction to adjust the distance between the first slideway 131 and the second slideway 132. In this way, the vertical moving member 140 can drive the second slideway 132 to be pressed on the first bracket 133 and the second bracket 134, so that the first bracket 133 and the second bracket 134 can rotatably clamp the first half mold 1111 and the second half mold 1112.

[0107] Alternatively, the vertical moving member 140 is a lifting cylinder. Of course, in other embodiments of the present application, the vertical moving member 140 can also be a linear motor or other parts that can output linear motion. Optionally, the number of the vertical moving member 140 is multiple, and multiple vertical moving members 140 are evenly arranged between the first slideway 131 and the second slideway 132. Exemplarily, the number of the vertical moving member 140 is four, and four vertical moving members 140 are supported at the four corners of the first slideway 131 and the second slideway 132.

[0108] 2 and 4, in one embodiment, the composite plate centrifugal manufacturing device 100 further includes baffles 150, which are disposed at both ends of the casting mold 111, and the baffles 150 protrude from the inner wall of the centrifugal casting chamber 1113. The baffles 150 are disposed at both axial ends of the casting mold 111 to prevent the partition member 112 from being separated from the casting mold 111, and at the same time, the baffles 150 can also stop the molten metal to prevent the molten metal from leaking from the ends.

[0109] The baffle 150 is arranged in an annular shape. After the baffle 150 is fixed to both ends of the casting mold 111, the thickness of the baffle 150 in the radial direction is greater than the sum of the thicknesses of the casting mold 111 and the composite tube blank 200 in the radial direction. In other words, the inner wall of the baffle 150 protrudes from the inner wall of the centrifugal casting chamber 1113 and also protrudes from the inner wall of the composite tube blank 200.

[0110] After the molten metal is injected into the centrifugal casting chamber 1113, the casting mold 111 rotates to allow the molten metal to flow in the centrifugal casting chamber 1113, so that the molten metal covers the inner wall of the centrifugal casting chamber 1113. At this time, the baffle 150 can stop the molten metal at both axial ends of the casting mold 111, preventing the molten metal from flowing out from the axial ends of the casting mold 111, so as to accurately form the composite tube blank 200.

[0111] After the partition member 112 is installed in the installation groove 1114 of the casting mold 111, baffles 150 are installed at both axial ends of the casting mold 111 to stop the molten metal. After the casting is completed, the baffles 150 are removed from both axial ends of the casting mold 111, and then the composite tube blank 200 can be pushed out of the centrifugal casting chamber 1113.

[0112] 1 to 3, in one embodiment, the composite plate centrifugal manufacturing device 100 further includes an ejection assembly 160, which is located at one end of the casting assembly 110 and is used to eject the composite tube blank 200 in the centrifugal casting chamber 1113. In FIG2, the ejection assembly 160 is located on the left side of the casting assembly 110, and the composite tube blank 200 is ejected from the centrifugal casting chamber 1113 by the ejection assembly 160.

[0113] After casting is completed, the baffle 150 is removed from both axial ends of the casting mold 111. Then, the ejection assembly 160 is ejected and extends into the centrifugal casting chamber 1113. The ejection assembly 160 can abut the left end of the composite tube blank 200. The ejection assembly 160 continues to apply a driving force to push the composite tube blank 200 out of the centrifugal casting chamber 1113.

[0114] During the ejection process of the ejection component 160, since the partition component 112 is partially arranged between the first half mold 1111 and the second half mold 1112, and partially formed integrally with the composite tube blank 200, and the partition component 112 is made of refractory material or ceramic material and is fragile, the pushing force of the ejection component 160 can easily break the partition component 112, and then the composite tube blank 200 is automatically separated into two parts without axial cutting.

[0115] Optionally, the ejection assembly 160 is an ejection cylinder, and the shape of the end of the ejection assembly 160 is adapted to the shape of the composite slab. In this way, the ejection assembly 160 can extend into the centrifugal casting chamber 1113 and accurately abut the end of the composite tube 200. It is worth noting that the specific structure of the ejection assembly 160 is a prior art and is not limited here.

[0116] Referring to Fig. 2, in one embodiment, the composite plate centrifugal manufacturing device 100 further includes a grabbing assembly 170 and a leveling assembly. The grabbing assembly 170 is used to grab the composite tube blank 200 and transfer it to the leveling assembly. The leveling assembly leveled the composite tube blank 200 to form a composite plate blank. The grabbing assembly 170 is disposed on the right side of the casting mold 111, as shown in Fig. 2.

[0117] After the ejection assembly 160 ejects the composite tube blank 200 from the casting mold 111, since the composite tube blank 200 has been separated into two parts, the grabbing assembly 170 can grab a composite tube blank 200 and transfer the composite tube blank 200 to the flattening assembly. The flattening assembly flattens the composite tube blank 200 to form a composite slab blank, and then the composite slab blank is hot rolled into a composite plate.

[0118] It is worth noting that the specific structures of the grabbing assembly 170 and the leveling assembly are prior art and will not be described in detail here.

[0119] When the composite plate centrifugal manufacturing device 100 of the present application is used to manufacture the composite plate, the first half mold 1111 and the second half mold 1112 of the casting mold 111 are combined to form a centrifugal casting chamber 1113, and a partition member 112 is provided in the mounting groove 1114 between the first half mold 1111 and the second half mold 1112, so that the partition member 112 protrudes from the inner wall of the centrifugal casting chamber 1113. Then, baffles 150 are installed at both axial ends of the casting mold 111.

[0120] Before casting the molten metal, an air isolation protective agent is added to the centrifugal casting chamber 1113, and after the air isolation protective agent is completely melted, the casting of the molten metal begins. It can be understood that the air isolation protective agent has the characteristics of low density and low melting point. In this way, during the casting of the molten metal, the air isolation protective agent is always in a molten state and is located in the inner circle of the centrifugal casting chamber 1113. The air isolation protective agent protects the molten metal from oxidation.

[0121] Then, at least two kinds of molten metals are injected into the centrifugal casting chamber 1113. One type of molten metal is injected into the centrifugal casting chamber 1113, and the air isolation protective agent that maintains the liquid state will pass through the molten metal and enter the inner surface layer of the centrifugal casting chamber 1113. Subsequently, when one type of molten metal has not yet completely solidified, another type of molten metal is cast. In this way, when one type of molten metal is still in a semi-solidified state, another type of molten metal is cast, so that the bonding surface of the two metals solidifies to form a metallurgical transition layer, and the bonding is more tightly combined.

[0122] Moreover, due to the lower density and centrifugal force, the air isolation protective agent maintained in liquid state will pass through the molten metal and enter the inner surface layer of the centrifugal casting chamber 1113. Similarly, multiple layers of different molten metals can be continuously cast, and the air isolation protective agent always remains on the inner surface to protect the latest cast molten metal from being oxidized by the air and absorb some inclusions.

[0123] After all the molten metals are solidified, the casting of the composite tube blank 200 is completed. Subsequently, the baffles 150 at both ends of the casting mold 111 are removed, and the composite tube blank 200 is pushed out of the centrifugal casting chamber 1113 using the push-out assembly 160. Since the partition components 112 made of refractory material or ceramic material are sandwiched between the composite tube blanks 200, the partition components 112 are easily broken during the pushing process, and then the composite tube blank 200 can be separated into two parts after the partition components 112 are broken.

[0124] After the push-out assembly 160 completely pushes the composite tube blank 200 out of the centrifugal casting chamber 1113, the composite tube blank 200 is completely separated into two parts, and the composite tube blank 200 does not need to be axially cut. Then, the grabbing assembly 170 grabs a part of the composite tube blank 200 to the flattening assembly for flattening, so that the composite tube blank 200 forms a composite slab, and then the composite slab is hot-rolled to form a composite plate.

[0125] The composite plate centrifugal manufacturing equipment 100 of the present application has a partition component 112 made of refractory material or ceramic material preset between the first half mold 1111 and the second half mold 1112 of the casting mold 111, and utilizes the fragile characteristics of the refractory material or ceramic material. After the casting is completed, the partition component 112 is broken during the process of pushing out the composite tube blank 200, so that the composite tube blank 200 is automatically separated into two parts without axial cutting, thereby greatly improving production efficiency and reducing production costs.

[0126] At the same time, a low melting point, low density air isolation protective agent is used to isolate air from the molten metal, ensuring that the bonding surfaces of different metal layers are isolated from the air during the casting process, thereby preventing oxidation and playing a protective role. In addition, the driven wheel 122 in the driving assembly 120 can move in the vertical direction, and cooperate with the first bracket 133 and the second bracket 134 that move in the horizontal direction to adapt to casting molds 111 of different diameters, making the specifications and models of the composite tube blank 200 more flexible and diversified.

[0127] Referring to Figures 1 to 5, Figure 5 is a process flow chart of the centrifugal manufacturing of the composite plate shown in Figure 1. The present application also provides a composite plate centrifugal manufacturing process, which is applied to the composite plate centrifugal manufacturing device 100 in any of the above embodiments, and the composite plate centrifugal manufacturing process includes the following steps:

[0128] A partition member 112 is placed on the inner wall of the centrifugal casting chamber 1113 of the casting mold 111, and the partition member 112 protrudes from the inner wall of the centrifugal casting chamber 1113;

[0129] Injecting air isolation protective agent into the centrifugal casting chamber 1113;

[0130] After the air isolation protective agent is completely melted, a type of molten metal is injected into the centrifugal casting chamber 1113, and the air isolation protective agent passes through the type of molten metal and enters the inner surface layer;

[0131] When one type of molten metal has not yet completely solidified, another type of molten metal is poured into the centrifugal casting chamber 1113, and the other type of molten metal passes through the air isolation protective agent and is placed between the one type of molten metal and the air isolation protective agent;

[0132] The casting is completed continuously in this way to form a composite tube blank 200;

[0133] The composite tube blank 200 is pushed out from the centrifugal casting chamber 1113, and the partition member 112 is broken to separate the composite tube blank 200;

[0134] The separated composite tube blank 200 is flattened, heat-matched and then pressed into a composite plate.

[0135] When the composite plate centrifugal manufacturing device 100 is used to manufacture the composite plate, the casting mold 111 has a centrifugal casting chamber 1113 inside, and a partition member 112 is arranged inside the centrifugal casting chamber 1113 so that the partition member 112 protrudes from the inner wall of the centrifugal casting chamber 1113. Then, baffles 150 are installed at both axial ends of the casting mold 111.

[0136] Before casting the molten metal, an air isolation protective agent is added to the centrifugal casting chamber 1113, and after the air isolation protective agent is completely melted, the casting of the molten metal begins. It can be understood that the air isolation protective agent has the characteristics of low density and low melting point. In this way, during the casting of the molten metal, the air isolation protective agent is always in a molten state and is located in the inner circle of the centrifugal casting chamber 1113. The air isolation protective agent protects the molten metal from oxidation.

[0137] Then, at least two kinds of molten metals are injected into the centrifugal casting chamber 1113. One type of molten metal is injected into the centrifugal casting chamber 1113, and the air isolation protective agent that maintains the liquid state will pass through the molten metal and enter the inner surface layer of the centrifugal casting chamber 1113. Subsequently, when one type of molten metal has not yet completely solidified, another type of molten metal is cast. In this way, when one type of molten metal is still in a semi-solidified state, another type of molten metal is cast, so that the bonding surface of the two metals solidifies to form a metallurgical transition layer, and the bonding is more tightly combined.

[0138] Moreover, due to the lower density and centrifugal force, the air isolation protective agent maintained in liquid state will pass through the molten metal and enter the inner surface layer of the centrifugal casting chamber 1113. Similarly, multiple layers of different molten metals can be continuously cast, and the air isolation protective agent always remains on the inner surface to protect the latest cast molten metal from being oxidized by the air and absorb some inclusions.

[0139] After all the molten metals are solidified, the casting of the composite tube blank 200 is completed. As shown in Figures 1 to 4, the outer layer of the composite tube blank 200 is one type of molten metal, the middle layer is another type of molten metal, and the outer layer is an air isolation protective agent.

[0140] Subsequently, the baffles 150 at both ends of the casting mold 111 are removed, and the composite tube blank 200 is pushed out of the centrifugal casting chamber 1113 using the ejection assembly 160. Since there are partition components 112 made of refractory material or ceramic material sandwiched between the composite tube blanks 200, the partition components 112 are easily broken during the ejection process, and the composite tube blank 200 can be separated into two parts after the partition components 112 are broken.

[0141] After the push-out assembly 160 completely pushes the composite tube blank 200 out of the centrifugal casting chamber 1113, the composite tube blank 200 is completely separated, and the composite tube blank 200 does not need to be axially cut. Then, the grabbing assembly 170 grabs a portion of the composite tube blank 200 to the flattening assembly for flattening, so that the composite tube blank 200 forms a composite slab, and then the composite slab is hot-rolled to form a composite plate.

[0142] In one embodiment, one type of molten metal is poured into another type of molten metal within 10s to 60s after casting. When the composite tube 200 is cast by two molten metals, the first molten metal is poured into the centrifugal casting chamber 1113 within 10s to 60s of casting.

[0143] When the composite tube 200 is cast by three kinds of molten metals, the first molten metal is cast into the centrifugal casting chamber 1113 within 10s to 60s of casting, and the third molten metal is cast into the centrifugal casting chamber 1113 within 10s to 60s of casting the second molten metal.

[0144] When the composite tube 200 is cast by more types of molten metals, various types of molten metals are cast in sequence according to the above method, and the multiple types of molten metals are solidified layer by layer. The principle is essentially the same as the above process and will not be repeated here.

[0145] The molten metal is in a state of not completely solidifying within 10s to 60s of casting. In other words, when one type of molten metal is not completely solidified, another type of molten metal is cast. In this way, when one type of molten metal is still in a semi-solidified state, another type of molten metal is cast, so that the bonding surface of the two metals solidifies to form a metallurgical transition layer, making the bonding closer.

[0146] Moreover, due to the lower density and centrifugal force, the air isolation protective agent maintained in liquid state will pass through the molten metal and enter the inner surface layer of the centrifugal casting chamber 1113. Similarly, multiple layers of different molten metals can be continuously cast, and the air isolation protective agent always remains on the inner surface to protect the latest cast molten metal from being oxidized by the air and absorb some inclusions.

[0147] In one embodiment, the air isolation protective agent includes borax and fluorite. The mass ratio of borax to fluorite is 1:1~9:1. That is, the air isolation protective agent is mainly made of borax and fluorite, and the mass ratio of the two is (Na2B4O7·10H2O): (CaF2) = 1:1-9:1. During the whole process of casting the molten metal, the air isolation protective agent always remains in a molten state due to the melting point, and the air isolation protective agent is always on the inner surface of the centrifugal casting chamber 1113 due to the lower density and centrifugal force, protecting all liquid metal from being oxidized by air during the solidification process.

[0148] The following is a specific example to illustrate the manufacture of composite panels:

[0149] Stainless steel 304 and plain carbon steel Q235B are centrifugally continuously cast, and then the composite slab is leveled, wherein Q235B is used as the outer surface layer of the composite tube 200, and stainless steel 304 is used as the inner surface layer of the composite tube 200. The casting mold 111 has a diameter of 1m and a length of 1m. The partition member 112 made of refractory material is installed in the installation groove 1114 of the casting mold 111.

[0150] Start to start the vacuum medium frequency furnace to melt 0.5t stainless steel 304 and the conventional medium frequency induction furnace to melt 4t plain carbon steel Q235B. Adjust the composition before casting, and control the superheat at 20-50℃. Put 100kg of air isolation protective agent into the liquid plain carbon steel Q235B, and start casting the liquid plain carbon steel Q235B into the centrifugal casting chamber 1113 after it melts. Start casting stainless steel 304 30s after the casting of plain carbon steel Q235B is completed. The centrifugal speed is above 800r / min.

[0151] After the stainless steel 304 solidifies, the composite tube 200 is pushed out of the centrifugal casting chamber 1113 by the push-out assembly 160. During the process of pushing out the composite tube 200, the partition member 112 made of refractory material is broken due to uneven force, and the composite tube 200 is automatically separated into two parts. A part of the composite tube 200 is grabbed by the grabbing assembly 170 and transported to the leveling machine for leveling, and rolled into a composite plate after being heated.

[0152] In this way, a composite tube blank 200 with outer plain carbon steel Q235B and inner stainless steel 304, 1m long, about 0.9m in average diameter, and about 0.2m in thickness was successfully trial-produced. After separation and leveling of the composite tube blank 200, the thickness ratio of different metal layers in the composite plate was about: plain carbon steel Q235B: stainless steel 304 = 8:1. The present application realizes a method for producing a composite tube blank 200 using the centrifugal principle, which is cutting-free and non-oxidizing, effectively improving the metal recovery rate of the composite plate, improving efficiency, reducing costs, and increasing economic benefits.

[0153] The centrifugal manufacturing process of the composite plate of the present application can realize the composite molding of two or more metal liquids. Two or more metal liquids are successively cast into the centrifugal casting chamber 1113 of a casting mold 111 to realize layer-by-layer solidification into a composite tube blank 200, and then the composite tube blank 200 is flattened into a plate. Not only does it not require vacuum welding or explosive bonding, but it also does not require cutting, and the manufacturing cost is lower, thereby improving the quality performance and economic benefits of the composite plate. At the same time, metallurgical bridging is achieved between the metal layers, and the product quality performance is more stable.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
