Description

Technical Field

[0001] This utility model relates to the field of copper-nickel alloy smelting technology, specifically a copper-nickel alloy smelting apparatus. Background Technology

[0002] Copper-nickel alloys possess excellent electrical conductivity, thermoelectric properties, and corrosion resistance, making them widely used in numerous fields such as electronics, communications, automotive, aerospace, shipbuilding, petroleum, chemical, construction, precision instruments, and medical devices. To meet the performance and specification requirements of various industries for copper-nickel alloy materials, continuous improvement and optimization of smelting equipment and processes are necessary to produce high-quality copper-nickel alloys.

[0003] Most copper-nickel alloy smelting equipment currently in use is not convenient for unloading the smelted copper-nickel alloy liquid. This inconvenience during operation leads to difficulties in unloading, resulting in prolonged unloading times. This not only increases the number of production cycles and reduces output per unit time, impacting overall production efficiency, but also causes excessive oxidation of the molten metal within the furnace, affecting the composition and properties of the copper-nickel alloy and reducing product quality. Furthermore, handling the difficult-to-unload molten metal may lead to unsafe operating methods, increasing the risk of accidents. Consequently, the smelting equipment suffers from poor production efficiency, quality, and safety. Additionally, the difficulty in installing and fixing the equipment at a specific workstation can cause instability during copper-nickel alloy smelting, preventing normal smelting operations and resulting in poor operational stability.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a tilting and feeding mechanism, facilitates the feeding of smelted copper-nickel alloy liquid. During use, the electric push rod is activated to tilt the electric arc furnace body and pour out the liquid. This avoids the difficulties in feeding the smelted copper-nickel alloy liquid, which would otherwise lead to feeding difficulties and long feeding times. This not only increases the number of production cycles and reduces the output per unit time, affecting the overall production efficiency, but also prevents the molten metal from being over-oxidized due to prolonged residence time in the furnace, affecting the composition and properties of the copper-nickel alloy and reducing product quality. Furthermore, workers handling difficult-to-feed molten metal may adopt unsafe operating methods, which could easily lead to safety accidents. This invention ensures the production efficiency, production quality, and safety of the smelting device.

During use, the smelting device is installed and fixed at the specific work position by the cooperation of bolts and threaded holes. This can avoid the situation where the device is unstable when smelting copper-nickel alloy due to the inconvenience of installing and fixing the smelting device at a specific work position, thus preventing it from carrying out normal smelting work and ensuring the stability of the smelting device during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 and Figure 2 As shown, this utility model provides the following technical solution, including an electric arc furnace body 1, a tilting and feeding mechanism 2 provided on the outer wall of the electric arc furnace body 1, a fixing block 4 fixedly connected to the outer wall of the electric arc furnace body 1, a second rotating shaft 5 rotatably connected to the top of the fixing block 4, a connecting block 6 fixedly connected to the top of the second rotating shaft 5, a cover plate 7 fixedly connected to one side of the connecting block 6, the bottom of the cover plate 7 being in contact with the top of the electric arc furnace body 1, an electrode rod 8 movably connected to the inner wall of the cover plate 7, and an installation and fixing mechanism 3 provided at the bottom of the support plate 202.

[0025] Specifically: When the smelting device is needed, it must first be installed and fixed at a specific workstation. This is achieved using the installation and fixing mechanism 3. Once installed and fixed, smelting can begin. The cover plate 7 is rotated, and the rotation of the second rotating shaft 5 on the fixing block 4 causes the connecting block 6 to rotate. The connecting block 6 then rotates the cover plate 7, allowing it to be opened. After opening the cover plate 7, copper-nickel raw materials are placed into the electric arc furnace body 1, and then... Rotate the cover plate 7 to cover the electric arc furnace body 1. Then, pass the electrode rod 8 through the cover plate 7 and insert it directly into the electric arc furnace body 1. A powerful electric arc is generated by the discharge between the electrode rod 8 and the furnace charge, which converts electrical energy into heat energy in the arc light. With the help of radiation and the direct action of the electric arc, the copper and nickel raw materials are heated and melted, thus carrying out smelting and completing the smelting work. After smelting, the smelted copper and nickel alloy liquid needs to be poured out and discharged. The smelted copper and nickel alloy liquid is poured out and discharged by the set pouring and discharging mechanism 2, thus completing the work.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the outer wall of the electric arc furnace body 1 is provided with a tilting and feeding mechanism 2. The tilting and feeding mechanism 2 includes a first rotating shaft 201. The first rotating shaft 201 is fixedly connected to the outer wall of the electric arc furnace body 1. A support plate 202 is rotatably connected to the outer wall of the first rotating shaft 201. A gear 203 is fixedly connected to one end of the first rotating shaft 201. A connecting frame 204 is fixedly connected to one side of the support plate 202. An electric push rod 205 is fixedly connected to one side of the connecting frame 204. A connecting plate 206 is fixedly connected to one end of the electric push rod 205. A moving block 207 is fixedly connected to the top of the connecting plate 206. A rack 208 is fixedly connected to the top of the moving block 207. The rack 208 meshes with the gear 203. Fixed plates 209 are fixedly connected to both sides of the moving block 207. A slide rail 210 is fixedly connected to the inner side of the fixed plate 209. A slider 211 is slidably connected to the outer wall of the slide rail 210. One side of the slider 211 is fixedly connected to one end of the support plate 202.

[0027] The process involves the following steps: After smelting, the molten copper-nickel alloy needs to be poured out. At this point, the cover plate 7 is opened via the second rotating shaft 5, and the electric push rod 205 is activated, causing it to shorten. The electric push rod 205 then moves the connecting plate 206, which in turn moves the moving block 207. During the movement of the moving block 207, the sliding of the slider 211 on the outer wall of the slide rail 210 ensures smoother and more stable movement. The moving block 207 then moves the rack 208. Through the interaction between the rack 208 and the gear 203, the rack 208 drives the gear 203 to rotate. The gear 203 then drives the first rotating shaft 201 to rotate on the inner wall of the support plate 202. The first rotating shaft 201 then rotates the electric arc furnace body 1, rotating it to a suitable angle to pour out the molten copper-nickel alloy, thus completing the pouring and unloading process.

[0028] like Figure 1 , Figure 5 and Figure 6 As shown, the bottom of the support plate 202 is provided with an installation and fixing mechanism 3. The installation and fixing mechanism 3 includes an installation plate 301. The bottom of the support plate 202 is fixedly connected to the installation plate 301. The installation plate 301 has a threaded hole 302 inside. The inner wall of the threaded hole 302 is threaded with a bolt 303.

[0029] Specifically: When the smelting device is needed, it must first be installed and fixed on a specific work station. At this time, the mounting plate 301 is placed tightly against the top of the work station, and then the threaded hole 302 in the mounting plate 301 is aligned with the threaded hole 302 on the work station. Then, the bolt 303 is rotated and inserted into the threaded hole 302 to fix the mounting plate 301 to the work station, thereby completing the installation and fixing work.

[0030] The working principle of this utility model is as follows: When the smelting device is needed, it must first be installed and fixed on a specific workstation. At this time, the mounting plate 301 is tightly attached to the top of the workstation. Then, the threaded hole 302 in the mounting plate 301 is aligned with the threaded hole 302 on the workstation. The bolt 303 is then rotated and inserted into the threaded hole 302 to fix the mounting plate 301 to the workstation, thus completing the installation and fixing work. After installation and fixing, smelting work can begin. At this time, the cover plate 7 is rotated... The rotation of the second rotating shaft 5 on the fixed block 4 causes the connecting block 6 to rotate, which in turn causes the cover plate 7 to rotate. Once the cover plate 7 is opened, the copper-nickel raw material is placed into the electric arc furnace body 1. The cover plate 7 is then rotated again to cover the electric arc furnace body 1. The electrode rod 8 is then inserted directly into the electric arc furnace body 1 through the cover plate 7. A powerful electric arc is generated through the discharge between the electrode rod 8 and the furnace charge, converting electrical energy into heat energy in the arc. The copper-nickel raw materials are heated and melted by the direct action of radiation and electric arc, thus completing the smelting process. After smelting, the molten copper-nickel alloy needs to be poured out. At this time, the cover plate 7 is opened by the second rotating shaft 5, and then the electric push rod 205 is activated, causing it to shorten. The electric push rod 205 drives the connecting plate 206 to move, and the connecting plate 206 drives the moving block 207 to move. During the movement of the moving block 207, the slider 211 moves along the slide rail 21. The sliding of the outer wall allows the moving block 207 to move more smoothly and steadily. The moving block 207 drives the rack 208 to start moving. Through the cooperation of the rack 208 and the gear 203, the rack 208 drives the gear 203 to start rotating. The gear 203 drives the first rotating shaft 201 to rotate on the inner wall of the support plate 202. The first rotating shaft 201 drives the electric arc furnace body 1 to start rotating, rotating the electric arc furnace body 1 to a suitable angle, and pouring out the copper-nickel alloy liquid inside the electric arc furnace body 1, thereby completing the pouring and unloading work.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
