[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0035] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0036] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects or their order.

[0037] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0038] This disclosure provides a titanium alloy rolling system, including a rolling module comprising at least two rolling mill units 500 arranged sequentially. In one example, there are two rolling mill units 500, one of which can be used for roughing and the other for intermediate rolling; or one of which can be used for roughing and the other for finishing. In another example, there are three rolling mill units 500, one of which can be used for roughing, one for intermediate rolling, and the other for finishing.

[0039] After rough rolling, titanium alloy parts undergo intermediate rolling and finish rolling. Hot rolling is used to produce titanium alloy parts. During the rolling process, the temperature cannot be controlled after the part is de-rolled, affecting subsequent rolling and the final microstructure and properties. Therefore, the selection of rolling temperature has a crucial impact on the final properties and strength of titanium alloys to ensure their internal microstructure and properties.

[0040] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3 A rolling deflection temperature control roller table can be installed between any two adjacent rolling mill units 500.

[0041] Optional, see Figures 1-3 The temperature control roller conveyor for the rolling mill includes a roller conveyor module 200, a heating and heat preservation module 100, and a control module (not shown in the figure). The roller conveyor module 200 is configured to drive the titanium alloy workpiece 300 placed on it. The heating and heat preservation module 100 is used to heat and maintain the temperature of the titanium alloy workpiece 300 to ensure its quality. The control module is configured to control the operation of the roller conveyor module 200 and the heating and heat preservation module 100.

[0042] In one embodiment of this disclosure, see [link to relevant documentation]. Figures 1-3 The heating and heat preservation module 100 has a heating channel, and the rolled piece 300 is located in the heating channel for heating and heat preservation.

[0043] In one example, see Figures 1-3The heating and insulation module 100 includes a bottom heating and insulation unit 5 and a top heating and insulation unit 6; the upper surface of the bottom heating and insulation unit 5 and the lower surface of the top heating and insulation unit 6 are adapted to overlap. In this disclosure, the heating and insulation module 100 adopts a detachable structure (the bottom heating and insulation unit 5 and the top heating and insulation unit 6 overlap). When the rolled piece 300 needs to be kept warm, the heating and insulation module 100 is in a closed state, and the bottom heating and insulation unit 5 and the top heating and insulation unit 6 are closed to form a heating channel. When the rolled piece 300 does not need to be kept warm, the heating and insulation module 100 is in an open state (at this time, the heating channel is open).

[0044] In one example, see Figure 1 and Figure 2 The bottom heating and insulation unit 5 includes a lower mounting bracket, a lower protective cover 51, and a lower heat insulation module 52. The lower protective cover 51 is mounted on the lower mounting bracket, and the lower heat insulation module 52 is disposed inside the lower protective cover 51. The lower heat insulation module 52 is used to maintain the temperature inside the heating channel, the lower protective cover 51 is used to protect the entire structure, and the lower mounting bracket is used to provide support for the lower protective cover 51 and strengthen the rigidity of the entire structure.

[0045] See Figure 1 and Figure 2 The top heating and insulation unit 6 includes an upper mounting bracket 64, an upper protective cover 61, an upper heat insulation module 62, and a heating element 63; the upper protective cover 61 is mounted on the upper mounting bracket 64, the upper heat insulation module 62 is located inside the upper protective cover 61, and the heating element 63 is located inside the upper heat insulation module 62.

[0046] Among them, the upper mounting bracket 64 overlaps at least on the lower mounting bracket, the upper protective cover 61 overlaps at least on the lower protective cover 51, and the upper heat insulation module 62 overlaps at least on the lower heat insulation module 52. In this way, the heating and heat preservation module 100 can be closed and opened to ensure the heating and heat preservation effect.

[0047] In this disclosure, the heating and insulation module 100 adopts a layered structure, with heating element 63, insulation module, protective cover, and mounting bracket arranged sequentially, which ensures heating and insulation while improving the safety of the entire structure. The control module can control the heating element and perform temperature control.

[0048] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 2 The top heating and heat preservation unit 6 has a first surface on the side near the bottom heating and heat preservation unit 5, and the bottom heating and heat preservation unit 5 has a second surface on the side near the top heating and heat preservation unit 6. When the first surface and the second surface are in contact, the heating and heat preservation module 100 is closed.

[0049] In one example, both the first and second surfaces are planar. In another example, both the first and second surfaces have a stepped surface. Optionally, the lower insulation module 52 of the bottom heating and insulation unit 5 is positioned lower than the lower protective cover 51, thereby forming a first stepped surface of the second surface at the upper end of the lower protective cover 51 and a second stepped surface of the second surface at the upper end of the lower insulation module 52. The upper insulation module 62 of the top heating and insulation unit 6 has a protrusion, and the upper protective cover 61 is flush with the non-protruding area of ​​the upper insulation module 62, thereby forming a first stepped surface of the first surface at the lower end of the non-protruding areas of the upper protective cover 61 and the upper insulation module 62, and forming a second stepped surface of the first surface at the lower end of the protrusion of the upper insulation module 62. The first stepped surface of the first surface is in contact with the first stepped surface of the second surface, and the second stepped surface of the first surface is in contact with the second stepped surface of the second surface. In other words, the width of the contact surface of the lower protective cover 51 is greater than the width of the contact surface of the upper protective cover 61, and the position of the lower heat insulation module 52 is lower than the position of the lower protective cover 51; the width of the upper protective cover 61 is less than the width of the lower protective cover 51, a portion of the upper heat insulation module 62 overlaps with the lower protective cover 51, and the remaining portion of the upper heat insulation module 62 overlaps with the lower heat insulation module 52. In this disclosure, the method of alternating the bonding surfaces of the two first step surfaces and the two second step surfaces is more conducive to improving the heat insulation effect, and even if there are some errors during bonding, a good heat insulation effect can still be achieved.

[0050] In one example, the lower mounting bracket, lower protective cover 51, and lower insulation module 52 in the bottom heating and insulation unit 5 can be integrally formed. In another example, see... Figure 1 and Figure 2 The bottom heating and insulation unit 5 may include a bottom heating and insulation unit and a side heating and insulation unit. In the bottom heating and insulation unit and the side heating and insulation unit, the lower mounting bracket, the lower protective cover 51, and the lower heat insulation module 52 can be integrally set. In this structure, the lower end face of the lower protective cover 51 of the side heating and insulation unit will overlap with the lower heat insulation module 52 of the bottom heating and insulation unit. This facilitates disassembly and arrangement, and reduces the difficulty of bottom installation and manufacturing.

[0051] In one embodiment of this disclosure, the lower insulation module 52 can be made of a composite material composed of high-temperature integrally molded refractory fiber cotton crystals and fiber insulation material, and the upper insulation module 62 can also be made of a composite material composed of high-temperature integrally molded refractory fiber cotton crystals and fiber insulation material. This composite material has good high-temperature resistance. Of course, the lower insulation module 52 and the upper insulation module 62 can also be made of other materials not shown.

[0052] In one embodiment of this disclosure, the upper mounting bracket 64 and the lower mounting bracket are made of steel.

[0053] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 The heating and insulation module 100 also includes at least one hydraulic control unit 7. In one example, the number of hydraulic control units 7 is one. In other examples, the number of hydraulic control units 7 can be two, three, etc., depending on the requirements, and this disclosure does not impose any limitations.

[0054] Optionally, the hydraulic control unit 7 includes a hydraulic cylinder 71, a hydraulic connecting rod 72, a connecting shaft 73, a connecting piece 74, and a fixed base 75. The connecting shaft 73 passes through the fixed base 75 and is rotatable relative to the fixed base 75. The connecting shaft 73 is connected to the upper mounting bracket 64 via the connecting piece 74. One end of the hydraulic connecting rod 72 is hinged to the output shaft of the hydraulic cylinder 71, and the other end is fixedly connected to the connecting shaft 73. In this example, the hydraulic cylinder 71 can drive the hydraulic connecting rod 72 to move, which in turn drives the upper mounting bracket 64 to move (the protective cover, etc., are fixed on the upper mounting bracket 64) via the connecting shaft 73 and the connecting piece 74, thereby realizing the opening and closing of the heating and insulation module 100.

[0055] In one embodiment of this disclosure, the roller module 200 includes a plurality of drive units 1, which are arranged sequentially along the movement direction of the titanium alloy rolled piece 300 (the arrangement direction of two adjacent rolling mills 500), and the drive units 1 are configured to drive the titanium alloy rolled piece 300 to run.

[0056] Optionally, the drive unit 1 may include a drive assembly 2 and a drive shaft 3, wherein the drive shaft 3 is placed within the heating channel, and both ends of the drive shaft 3 extend through the bottom heating and insulation unit 5 (understandably, the bottom heating and insulation unit 5 is positioned higher than the drive shaft 3). The power output end of the drive assembly 2 is connected to one end of the drive shaft 3, and the drive assembly 2 is configured to drive the drive shaft 3 to rotate, so that under the action of its rotation, the titanium alloy rolled piece 300 can move from the previous rolling mill 500 to the next rolling mill 500. In one example, the drive assembly 2 is a motor. In another example, the drive assembly 2 may also be other structures not shown.

[0057] Optionally, the control module can control the speed of the drive component 2 to be adjustable, for example, within the range of 0.3-2.5 m / s.

[0058] Optionally, taking the drive assembly 2 as a motor as an example, both ends of the drive shaft 3 pass through the bottom heating and insulation unit 5 and are connected to bearing seats 8. One end of the drive shaft 3 passes through the corresponding bearing seat 8 and is coaxially connected to the output end of the motor. It can be understood that the bearing seat 8 is located outside the heating and insulation module 100.

[0059] In one embodiment of this disclosure, a V-shaped roller 4 is provided on the drive shaft 3 in the heating channel. The V-shaped roller 4 has a V-shaped region for placing the titanium alloy workpiece 300. The V-shaped rollers 4 are arranged parallel to each other (the drive shafts 3 are arranged parallel to each other), and the axial direction of the V-shaped roller 4 is perpendicular to the movement direction of the workpiece 300. The height of the V-shaped region is calculated from the highest point of its central V-shaped region. In one example, the material of the V-shaped roller is Cr25Ni20; of course, in other examples, other materials can be used. In this disclosure, using V-shaped rollers to contact the workpiece is beneficial for controlling the deformation of the high-temperature workpiece.

[0060] In one embodiment of this disclosure, the bearing housing 8 has a cooling channel (the cooling channel has a liquid inlet and a liquid outlet) that connects to the outside. In this disclosure, the cooling channel on the bearing housing 8 allows for the introduction and export of cooling medium, thereby achieving cooling of the bearing housing and ensuring that the roller conveyor assembly has a stable and high-performance working state.

[0061] In this example, the outlets of the cooling channels on each bearing housing 8 are integrated through connecting pipes to achieve unified treatment of the cooling medium.

[0062] In this example, the bearing in bearing housing 8 is lubricated with dry oil.

[0063] In one embodiment of this disclosure, the titanium alloy rolling detonation temperature control roller table further includes a lifting baffle 400, which is located at the end of the titanium alloy rolling detonation temperature control roller table, i.e., on the discharge side of the titanium alloy rolling detonation temperature control roller table (roller table module 200). The lifting baffle 400 has a first position and a second position. In the first position, the position of the lifting baffle 400 is not higher than the position of the V-shaped area of ​​the V-shaped roller (preferably, the position of the lifting baffle 400 is lower than the position of the V-shaped area of ​​the V-shaped roller); in the second position, the position of the lifting baffle 400 is higher than the position of the V-shaped area of ​​the V-shaped roller (the position of the lifting baffle 400 is higher than the position of the rolled piece 300 in the V-shaped area). In this disclosure, after the roller table module 200 is closed, the rolled piece 300 will continue to move under inertia. The lifting baffle 400 in the second position can limit the movement of the rolled piece 300, preventing the rolled piece 300 from sliding down under inertia.

[0064] Optionally, the lifting baffle 400 may include a lifting mechanism and a baffle body, with the power output end of the lifting mechanism connected to the baffle body. In one example, the lifting mechanism may be a cylinder. In other examples, the lifting mechanism may be other structures not shown.

[0065] In one embodiment of this disclosure, the temperature control roller conveyor can be mounted on the fixed base 600.

[0066] The scheme disclosed herein allows for temperature control and conveying of the titanium alloy roll after the roll is removed during the rolling process, thereby ensuring the internal structure and properties of the titanium alloy.

[0067] The temperature-controlled roller conveyor in this disclosure has two conveying modes:

[0068] The first type is the temperature control mode, where the heating and insulation module 100 is closed, the heating element 63 is open, and the roller conveyor module 200 conveys the rolled piece at a speed of 0.3-2.5m / s. It is mainly used for temperature control of the rolled piece after it is de-rolled during continuous rolling to ensure that the temperature of the rolled piece is within a certain range.

[0069] The second mode is the cooling mode. When the finished product is obtained directly after the rolled piece is removed from the roll, the heating and heat preservation module 100 is opened by the hydraulic cylinder 71, so that the rolled piece 300 gradually slows down and stops during the conveying process, and the lifting baffle 400 is controlled to be in the second position to limit and protect the rolled piece 300.

[0070] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
