Description

Technical Field

[0001] The present application relates to the technical field of metallurgical equipment, and in particular to a device for reducing the generation of zinc oxide slag during the casting process of zinc alloy ingots. Background Art

[0002] Zinc alloy is an alloy composed of zinc and other elements. Commonly added alloying elements include aluminum, antimony, copper, magnesium, titanium, silicon, etc. Zinc alloy is also called zinc-based alloy, which is generally divided into binary alloy, ternary alloy and multi-element alloy. Binary zinc-based alloy generally refers to zinc-aluminum alloy; ternary zinc-based alloy generally refers to zinc-aluminum-silicon, zinc-aluminum-magnesium, zinc-aluminum-antimony alloy; multi-element alloy generally refers to zinc-aluminum and other trace metals. Zinc alloy has low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and waste materials are easy to recycle and remelt, but the creep strength is low and it is easy to cause dimensional changes due to natural aging. Zinc alloy is widely used in manufacturing, automotive industry, electronics industry, construction and decoration, medical equipment and other fields. It provides high-strength, corrosion-resistant and highly plastic material options for all walks of life, and promotes the development of modern industry.

[0003] When zinc alloy is cast, the zinc alloy liquid is introduced from the melting furnace into the ingot mold through guiding mechanisms such as chutes. When the alloy liquid flows in the whole process, its surface will be oxidized by the air to form zinc oxide slag. When cast on the alloy ingot, it will also be oxidized by the air to form zinc oxide slag. Especially for ingot casting, due to the large surface area of ​​the ingot mold, a large amount of zinc oxide slag is easily generated on the surface during the process of falling into the ingot mold during casting. The mixing of these zinc oxide slags into the alloy will cause the slag content in the alloy to be too high, thereby causing the alloy product to be unqualified. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related art, the present application provides a device for reducing the generation of zinc oxide slag during the casting process of zinc alloy ingots, which can reduce the generation of zinc oxide slag during casting.

[0005] The present application discloses a device for reducing the generation of zinc oxide slag during the casting process of zinc alloy ingots, comprising an electric furnace; and a chute, wherein the chute is constructed with a trough-shaped chute feed port and a tubular chute discharge end integrally formed with a trough body, and a detachable chute cover is provided on the trough body to seal the entire trough body;

[0006] Feeding port, liquid collecting hopper, ingot casting mold;

[0007] Among them, the ingot mold is arranged below the discharge port, the discharge end of the chute is detachably sealed and connected to the discharge port, the liquid collecting hopper is arranged in a funnel shape, and a liquid collecting pipe is detachably arranged at the bottom of the liquid collecting hopper, and the liquid collecting pipe is inserted into the bottom of the ingot mold, and the rim of the liquid collecting hopper is higher than the discharge port.

[0008] Optionally, the discharge port is configured as a bent pipe, and a lower partition is provided at the bottom of the connection between the discharge port and the chute discharge end, and an upper partition is provided at the top.

[0009] Optionally, after the material is accumulated at the chute feed port, the discharge amount of the discharge port of the electric furnace is the same as the discharge amount of the lower material port, and the discharge amount of the lower material port is the same as the discharge amount of the collecting pipe.

[0010] Optionally, the liquid collecting pipe is configured to be formed by splicing and fastening two semicircular tubes.

[0011] Optionally, handrails are connected to both ends of the liquid collecting bucket.

[0012] The technical solution provided by this application may have the following beneficial effects:

[0013] This device sets the two ends of the chute as a fully enclosed pipe conveying mechanism except for the inlet and outlet. In this way, the area of ​​the alloy solution in contact with the air during the diversion process can be reduced, thereby reducing the probability of the alloy oxidizing to generate zinc oxide slag. At the same time, the chute cover is detachable and convenient to remove after all work is completed to clean the inside of the chute. The present application uses a liquid collecting hopper to receive the alloy solution, and at the same time uses a liquid collecting pipe to guide the distance of the alloy solution falling. During casting, the liquid collecting pipe is inserted into the bottom of the ingot mold below the alloy solution immersed in the ingot mold. In this way, when the alloy solution is cast, only the surface of the liquid collecting hopper produces zinc oxide slag, and the surface of the ingot mold forms a zinc oxide slag mold, and the alloy solution is poured in from below the liquid surface, thereby reducing the production of zinc oxide slag in the ingot mold. The production of zinc oxide slag and its mixing into the alloy are reduced as a whole, improving production quality.

[0026] In view of the above problems, an embodiment of the present application provides a device for reducing the generation of zinc oxide slag during the casting process of zinc alloy ingots. The technical solution of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 The device for reducing the generation of zinc oxide slag during the casting process of zinc alloy ingots shown in the figure comprises an electric furnace 1; and a chute 2, wherein the chute 2 is constructed with a trough-shaped chute feed port 21 and a tubular chute discharge end 22 integrally formed with the trough body, and a detachable chute cover 23 is provided on the trough body to seal the entire trough body;

[0028] Feeding port 3, liquid collecting hopper 4, ingot casting mold 5;

[0029] In the present device, the electric furnace 1 is an induction furnace for molten alloy. A discharge port 11 is provided on one side of the electric furnace 1 to discharge the molten alloy for convenient pouring. A chute 2 is provided below the discharge port 11 to transport the alloy solution. At the same time, in order to facilitate continuous pouring, a chute column 7 is provided at the bottom of one end of the chute 2, and an electric trolley 6 is provided at the bottom of the other end. The two ends of the chute 2 can rotate left and right and up and down on the chute column 7 and the electric trolley 6 respectively. At the same time, the electric trolley 6 actively drags the chute column 7 to rotate and replace the pouring ingot mold 5.

[0030] In the present application, the ingot mold 5 is arranged below the discharge port 3, the chute discharge end 22 is detachably sealed and connected to the discharge port 3, the liquid collecting hopper 4 is arranged in a funnel shape, and a liquid collecting pipe 41 is detachably arranged at the bottom of the liquid collecting hopper 4, and the liquid collecting pipe 41 is inserted into the bottom of the ingot mold 5, and the bucket edge of the liquid collecting hopper 4 is higher than the discharge port 3.

[0031] In the present application, both ends of the chute 2 are set as a fully enclosed pipe conveying mechanism except for the inlet and outlet, so that the area of ​​the alloy solution in contact with the air during the diversion process can be reduced, thereby reducing the probability of the alloy oxidizing to generate zinc oxide slag. At the same time, the chute cover 23 is detachable and convenient to remove after all the work is completed to clean the inside of the chute 2. After the diversion of the chute 2, the alloy solution falls into the ingot mold 5 through the discharge port 3. Here, the alloy solution continuously flows out and contacts with the air and is easily oxidized and melted into the ingot. The present application uses a collecting hopper 4 to receive the alloy solution, and at the same time uses a collecting pipe 41 to guide the distance of the alloy solution falling. When pouring, the collecting pipe 41 is inserted into the bottom of the ingot mold 5 and the alloy solution in the ingot mold 5 is immersed in the ingot mold 5. In this way, when the alloy solution is poured, only the surface of the collecting hopper 4 produces zinc oxide slag, and the surface of the ingot mold 5 forms a zinc oxide slag mold, and the alloy solution is poured from below the liquid surface, therefore, The production of zinc oxide slag in the ingot mold 5 is reduced. The production of zinc oxide slag and its mixing into the alloy are reduced overall, improving production quality.

[0032] In one embodiment, Figure 3 As shown, the discharge port 3 is configured as a bent pipe for diversion, and a lower partition 31 is provided at the bottom of the connection with the chute discharge end 22, and an upper partition 32 is provided at the top. In this way, when the alloy solution first flows into the chute 2, its surface will be oxidized to form a zinc oxide slag layer, and when the entire closed chute flow channel is filled, the top and bottom surfaces are blocked by the partitions, thereby blocking the zinc oxide slag layer.

[0033] In one embodiment, Figure 2 As shown, after the material is accumulated at the chute feed port 21, the discharge amount of the discharge port 11 of the electric furnace 1 is the same as the discharge amount of the discharge port 3, and the discharge amount of the discharge port 3 is the same as the discharge amount of the collecting pipe 41. In this way, the air in the entire flow channel is completely discharged, reducing the contact time of the alloy solution with the air, and no new zinc oxide slag is formed except for the surface layer formed at the beginning, thereby reducing the generation of zinc oxide slag.

[0034] In one embodiment, Figure 2 As shown, the liquid collecting pipe 41 is configured to be formed by splicing and fastening two semicircular tubes, which is convenient for later cleaning and maintenance.

[0035] In one embodiment, Figure 4 As shown, handrails 42 are connected to both ends of the liquid collecting hopper 4 to facilitate movement.

[0036] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
