Description

Technical Field

[0001] This utility model relates to the field of metallurgy, specifically to an intelligent quantitative continuous following casting device. Background Technology

[0002] In the zinc smelting industry, the relatively primitive method of zinc ingot casting typically involves pouring molten zinc into a mold and allowing it to cool and solidify to form a zinc ingot. While this method is simple, it is inefficient for large-scale production and requires manual operation and monitoring. During casting, the molten zinc is exposed to air for extended periods, which can easily lead to oxidation and the formation of a large amount of zinc scale that needs to be manually cleaned, resulting in poor casting quality.

[0003] Traditional continuous casting process utilizes a zinc ingot continuous casting device, which includes a robotic ladle or swing-arm ladle, casting molds, and a conveyor belt. The robotic arm or rotating shaft scoops molten zinc and pours it into the mold. The conveyor chain moves at a constant speed, and the robotic arm or swing-arm ladle automatically scoops and pours the zinc according to a rhythm, requiring no human intervention throughout the process. However, during scooping and pouring, the molten zinc is constantly exposed to air, resulting in a large amount of zinc plating on the surface of the cast ingots that needs to be removed. Furthermore, it is difficult to achieve quantitative and continuous control of the molten zinc during casting. Utility Model Content

[0004] To address the technical problem in existing zinc ingot casting processes where zinc molten zinc easily produces zinc oxide scale, requiring additional manual processing and resulting in poor casting quality, this invention provides an intelligent quantitative continuous following casting device.

[0005] An intelligent quantitative continuous following casting device includes a melting furnace and a centrifugal pump and a riser well located within the melting furnace. The outlet of the centrifugal pump is connected to the bottom of the riser well. The top of the riser well extends out of the melting furnace and is connected to a chute. A casting trough is located below the end of the chute away from the riser well. A conveyor belt is located at the casting port of the casting trough, and a mold is mounted on the conveyor belt. A mounting plate and a frame are located at the bottom of the casting trough. The bottom of the casting trough is hinged to the mounting plate. A casting drive device is provided between the casting trough and the mounting plate to drive the casting trough to rotate about the hinge point between the casting trough and the mounting plate. A following drive device is provided between the mounting plate and the frame, and the mounting plate is slidably connected to the frame through the following drive device.

[0006] In a preferred embodiment of the intelligent quantitative continuous following casting device provided by this utility model, the casting driving device is a casting driving cylinder, one end of which is hinged to the mounting plate and the other end of which is hinged to the casting trough.

[0007] In a preferred embodiment of the intelligent quantitative continuous following casting device provided by this utility model, the following drive device includes a guide rail and a following drive cylinder; the guide rail is located on the top of the frame and is arranged along the length direction of the conveyor belt, and the mounting plate is slidably connected to the guide rail; one end of the following drive cylinder is hinged to the frame, and the other end is hinged to the mounting plate.

[0008] In a preferred embodiment of the intelligent quantitative continuous following casting device provided by this utility model, a chute gate is provided at one end of the chute near the casting tank.

[0013] In a preferred embodiment of the intelligent quantitative continuous following casting device provided by this utility model, a heating rod is provided inside the liquid riser well.

[0014] Compared to existing technologies, the intelligent quantitative continuous following casting device provided by this utility model uses a centrifugal pump to allow molten zinc to enter the riser well and the chute from the bottom of the riser well. A layer of zinc oxide scale forms on the surface of the molten zinc in the riser well and the chute. The molten zinc entering from the bottom of the riser well always flows under the zinc oxide scale, which acts as an oxygen barrier. The flame torch burns to isolate oxygen and keep the molten zinc warm, reducing oxidation. A heating rod is installed in the riser well to keep the molten zinc warm. The following drive device allows the casting tank to follow the mold, ensuring that the casting port of the casting tank is always in the center of the mold during casting. The laser level gauge at the riser well and the chute gate control the flow rate of molten zinc from the chute into the casting tank. The laser level gauge at the casting tank and the casting drive device work together to control the amount of molten zinc poured into the mold from the casting tank. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please refer to the following: Figures 1 to 4 These are, respectively, a structural schematic diagram of an intelligent quantitative continuous following casting device, a structural schematic diagram of a centrifugal pump and chute, a structural schematic diagram of a casting tank, and an enlarged view of point A therein, provided by this utility model.

[0021] The intelligent quantitative continuous following casting device includes a smelting furnace 1, which is equipped with two centrifugal pumps 2 and two liquid riser wells 4. In this embodiment, one smelting furnace 1 is equipped with two conveyor belts 15, that is, two casting tanks 11 for casting operations.

[0022] Each centrifugal pump 2 is connected to a motor 3, which is located outside the smelting furnace 1. The outlet of the centrifugal pump 2 is connected to the bottom of the riser well 4, and the top of the riser well 4 extends out of the smelting furnace 1 and is connected to a chute 7. A heating rod 6 is installed inside the riser well 4. A laser level gauge 5 is installed at the top of the riser well 4, which vertically illuminates the center of the liquid surface in the riser well 4.

[0023] The chute 7 is inclined, forming a 3-degree angle with the horizontal plane along its length, and the end closer to the riser well 4 is higher than the end farther from the riser well 4. A chute cover plate 9, adapted to the top surface of the chute 7, is provided on the top of the chute 7. A chute gate plate 8 is provided at the end of the chute 7 furthest from the riser well 4.

[0024] A casting tank 11 is provided below the end of the chute 7 away from the liquid riser 4. A conveyor belt 15 is provided below the casting port of the casting tank 11, and multiple molds 12 are provided on the conveyor belt 15.

[0025] The bottom of the casting tank 11 is provided with a mounting plate 16 and a frame 17. Figure 4 From this perspective, the bottom of the casting trough 11 is hinged to the mounting plate 16, and a casting drive device 14 is provided on the right side. The casting drive device 14 is a casting drive cylinder, one end of which is hinged to the right side of the mounting plate 16, and the other end is hinged to the right side of the casting trough 11.

[0026] A following drive device 13 is provided between the mounting plate 16 and the frame 17. The following drive device 13 includes a guide rail and a following drive cylinder. The guide rail is fixed to the top of the frame 17 and is arranged along the length direction of the conveyor belt 15. The bottom of the mounting plate 16 is provided with a slider adapted to the guide rail. One end of the following drive cylinder is hinged to the frame 17, and the other end is hinged to the mounting plate 16, driving the mounting plate 16 to move along the guide rail.

[0027] Another laser level gauge 5 is provided above the casting tank 11, and the laser level gauge 5 is vertically irradiated at the center of the liquid surface at the inlet of the casting tank 11.

[0028] The top of the casting tank 11 is also provided with a flame gun 10, and the flame of the flame gun 10 is directed towards the inside of the casting tank 11.

[0029] In practice, the motor 3 drives the centrifugal pump 2 to rotate, and the centrifugal pump 2 drives the molten zinc in the smelting furnace 1 to the riser well 4. The liquid level in the riser well 4 rises and flows into the chute 7, at which time the chute gate 8 is in the closed state. The laser level gauge 5 above the riser well 4 detects the liquid level height in the riser well 4, and adjusts the rotation speed of the motor 3 according to the liquid level height detected by the laser level gauge 5 to control the liquid level in the riser well 4 to be stable at a preset value. The heating rod 6 heats the molten zinc in the riser well 4.

[0030] When the chute gate 8 is opened, molten zinc flows from the chute 7 into the casting tank 11. The laser level gauge 5 at the casting tank 11 detects the liquid level height in the casting tank 11, and determines whether the amount of molten zinc in the casting tank 11 has reached a preset value to meet the casting requirements based on the detected liquid level change signal.

[0031] During casting, the casting drive cylinder extends, causing the casting tank 11 to rotate around the hinge point between the casting tank 11 and the mounting plate 16. The molten zinc in the casting tank 11 is then poured into the mold 12 from the left casting port. When the laser level gauge 5 at the casting tank 11 detects that the liquid level in the casting tank 11 is equal to the design height, the extension length of the casting drive cylinder is the standard preset length. When the detected liquid level is higher than the design height, the extension length of the casting drive cylinder decreases relative to the standard preset length, and the swing angle of the casting tank 11 decreases, thereby controlling the casting volume. When the detected liquid level is lower than the design height, the extension length of the casting drive cylinder increases relative to the standard preset length, and the swing angle of the casting tank 11 increases, thereby controlling the casting volume.

[0032] During the rotation of the casting tank 11 to pour molten zinc, the follow-drive cylinder drives the mounting plate 16 and the casting tank 11 to move. The direction and speed of their movement are the same as the direction and speed of the mold 12 on the conveyor belt 15, ensuring that the pouring port remains centered on the mold 12 during casting. After casting is complete, the follow-drive cylinder returns the casting tank 11 to its pre-casting position.

[0033] The flame gun 10 on the casting tank 11 continuously sprays flames into the casting tank 11.
