Description

Technical Field

[0001] This utility model belongs to the field of continuous casting furnace technology, specifically referring to an oxygen-free copper rod continuous casting furnace using the upward drawing method. Background Technology

[0002] The upward drawing oxygen-free copper rod continuous casting furnace is a key piece of equipment used to produce oxygen-free copper rods. The raw materials are added to the melting furnace through a feeder and heated to melt in an oxidizing atmosphere. During the melting process, compressed air is blown in to carry out oxidation, causing impurities to form slag that floats on the surface of the melt. Then, it is transported to the crystallizer through a medium-frequency holding furnace for rapid crystallization to form copper rods.

[0003] While existing continuous casting furnaces can meet the melting requirements of copper materials, they still have some shortcomings: the slag on the surface of the molten copper in the furnace is not easy to clean off in a timely manner, which affects the quality of copper rod crystallization. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, after the copper material in the continuous casting furnace has melted, it is not convenient to clean off the upper layer of slag in a timely manner.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A continuous casting furnace for oxygen-free copper rods using the upward drawing method includes a base, the upper end of which is disposed on a melting furnace, a medium-frequency holding furnace is disposed on one side of the base, the melting furnace and the medium-frequency holding furnace are connected by a connecting pipe, a crystallizer is connected above the medium-frequency holding furnace, heating equipment is disposed around the perimeter of the melting furnace, a rotary mechanism is disposed on one side of the base, a rotary shaft is rotatably disposed in the rotary mechanism, a crossbeam is fixedly connected to the upper end of the rotary shaft, a vertical frame is fixedly connected to the upper end of the crossbeam, and a slag removal device is disposed on the vertical frame to remove impurities in the melting furnace.

[0006] Furthermore, the slag removal device includes a motor, which is fixedly connected to the upright frame. The output end of the motor is provided with a gear. An electric push rod is fixedly connected downward to the top wall of the upright frame. The output end of the electric push rod is connected to a toothed column. The toothed column is meshed with the gear. A rotating shaft is fixedly connected to the lower end of the toothed column. A slag removal hopper is fixedly connected to the lower end of the rotating shaft.

[0007] Furthermore, the output end of the electric actuator is connected to the gear column via a bearing.

[0008] Furthermore, the lower end of the slag hopper is provided with a drain valve, the slag hopper is inverted L-shaped and has a hollow cavity, and the length of the slag hopper is equal to the inner radius of the melting furnace.

[0009] Furthermore, the rotary mechanism includes a housing located on one side of the base, the rotary column rotating within the housing via bearings, a gear three fixedly connected to the rotary shaft, a motor two fixedly connected within the housing, and the output end of the motor two being equipped with a gear two that meshes with the gear three.

[0010] Furthermore, the heating device is a common high-frequency coil heating method.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This utility model is equipped with a slag removal device. An electric push rod drives the toothed column to rise and fall. During the rising and falling process, it maintains a meshing relationship with the first gear until the slag removal bucket is located at the surface of the copper liquid in the melting furnace. This makes the opening of the slag removal bucket slightly lower than the liquid surface. The toothed column rotates through the meshing of the first gear, and the toothed column drives the rotating shaft to rotate. Thus, the slag removal bucket will rotate in the melting furnace to remove impurities on the liquid surface.

[0013] 2. This utility model, by setting up a rotary mechanism, drives the second motor to rotate the second gear and meshes with the third gear to rotate, which can rotate the slag hopper to one side of the melting furnace, and discharge the impurities in the slag hopper through the drain valve.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1-4 This utility model discloses an oxygen-free copper rod continuous casting furnace using an upward drawing method, comprising a base 1, with the upper end of the base 1 disposed on a melting furnace 2, and a medium-frequency holding furnace 3 disposed on one side of the base 1. The melting furnace 2 and the medium-frequency holding furnace 3 are connected by a connecting pipe 5. A crystallizer 4 is connected above the medium-frequency holding furnace 3. A heating device 6 is disposed around the melting furnace 2, which is a common high-frequency coil heating method. A rotary mechanism 7 is disposed on one side of the base 1, and a rotary shaft 16 is rotatably disposed in the rotary mechanism 7. A crossbeam 9 is fixedly connected to the upper end of the rotary shaft 16, and a vertical frame 10 is fixedly connected to the upper end of the crossbeam 9. A slag removal device 11 is disposed on the vertical frame 10 to remove impurities in the melting furnace 2.

[0022] like Figure 1-4 The slag removal device 11 includes a motor 12, which is fixedly connected to the upright frame 10. The output end of the motor 12 is equipped with a gear 13. An electric push rod 14 is fixedly connected downwards to the top wall of the upright frame 10. The output end of the electric push rod 14 is connected to a gear column 15, which is connected to the gear column 15 via a bearing. The gear column 15 meshes with the gear 13. A rotating shaft 16 is fixedly connected to the lower end of the gear column 15, and a slag removal hopper 17 is fixedly connected to the lower end of the rotating shaft 16. A drain valve 22 is provided at the lower end of the slag removal hopper. The slag hopper 17 is an inverted L-shape with a hollow cavity. The length of the slag hopper 17 is equal to the inner radius of the melting furnace 2. The rotation of the slag hopper 17 will remove impurities from the molten copper in the melting furnace 2. Impurities entering the slag hopper 17 will be stored and discharged through the drain valve 22. The electric push rod 14 pushes the toothed column 15 down, allowing the slag hopper 17 to reach a suitable height in the melting furnace 2. The gear 13 meshes with the toothed column 15 to rotate, driving the slag hopper 17 to rotate, which can remove surface impurities from the molten copper in the melting furnace 2.

[0023] like Figure 1-3The rotary mechanism includes a housing 18, which is located on one side of the base 1. The rotary column 168 rotates in the housing 18 via bearings. A gear 19 is fixedly connected to the rotary shaft 16. A motor 20 is fixedly connected in the housing 18. The output end of the motor 20 is provided with a gear 21 that meshes with the gear 19. By meshing the gear 21 with the gear 19, the rotary shaft 16 is rotated, thereby rotating the slag hopper 17 to one side of the melting furnace 2 to clean impurities.

[0024] In practical use, when producing oxygen-free copper rods, copper material is added to the melting furnace 2, and the melting furnace 2 is heated by the heating device 6, so that the copper material melts into copper liquid. Impurities will float on the upper layer of the copper liquid. The electric push rod 14 pushes the toothed column 15, which will remain engaged with the gear 13. The rotating shaft 16 drives the slag hopper 17 to move down. The opening of the slag hopper 17 is below the copper liquid. By starting the motor 12, the gear 13 engages with the toothed column 15 to rotate, driving the rotating shaft 16 to rotate. The rotating shaft 16 drives the slag hopper 17 to rotate, so that the impurities on the surface of the copper liquid will enter the slag hopper 17.

[0025] After the slag is removed, the slag hopper 17 is raised above the melting furnace 2. By starting the motor 20, the gear 21 meshes with the gear 3 19 to rotate, driving the rotating column 168 to rotate and rotate the slag hopper 17 to one side. Then, the discharge valve is opened to discharge the impurities.

[0026] Open the connecting pipe 5 to transport the molten copper in the melting furnace 2 to the medium-frequency holding furnace 3. During the holding and settling process, reduction and deoxidation are carried out. The temperature of the molten copper is controlled at 1150℃±10℃. The continuous casting machine can be fixed above the medium-frequency holding furnace 3. The molten copper crystallizes rapidly in the crystallizer 4, so that copper rods can be produced continuously.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
