[0024] Example 1 An electrode pressing and releasing speed buffer device, as described in a preferred embodiment of this utility model, is as follows: Figures 1-8As shown, the furnace includes a submerged arc furnace body 1, an iron tap 2, an alloy 3, slag 4, ore 5, a flange 6, a large vertical cylinder 7, an electrode body 701, an extrusion rod 8, an extrusion block 9, a first brake ring 10, a first hydraulic cylinder 11, a first stabilizing plate 12, a first gate plate 13, a first pressure reducing rod 14, a buffer ring 15, a horizontal plate 16, a threaded pressure reducing rod 17, a second pressure reducing rod 18, a spring 19, a control box 20, a short mesh 21 and a copper tile 22, a second brake ring 23, a second hydraulic cylinder 24, a second gate plate 25, and a second stabilizing plate 26. The iron tap 2 is embedded in the lower left and right sides of the submerged arc furnace body 1.

The alloy 3, the slag 4 is in the lower middle layer of the inner wall of the submerged arc furnace body 1, the ore 5 is in the upper layer of the inner wall of the submerged arc furnace body 1, a limiting plate 601 is embedded in the upper part of the submerged arc furnace body 1, the electrode body 701 is placed on both sides of the limiting plate 601, the lower part of the electrode body 701 is placed inside the submerged arc furnace body 1, the extrusion rod 8 is welded to the bottom end of the telescopic rod of the large vertical cylinder 7, the extrusion block 9 is provided at the bottom end of the extrusion rod 8, the first brake ring 10 is installed at the bottom of the extrusion block 9, the first stabilizing plate 12 is threadedly provided on the outer wall of the first brake ring 10 at intervals, the number of the first stabilizing plate 12 is at least four, the first stabilizing plate 12 is installed at intervals between the first brake ring 10 and the first brake ring 10. The system includes a first hydraulic cylinder 11, with a first gate plate 13 welded to the inner end of the telescopic rod of the first hydraulic cylinder 11. The inner wall of the first gate plate 13 contacts the electrode body 701. A first pressure-reducing rod 14 is fixedly connected to the rear side of the outer wall of the first brake ring 10. A buffer ring 15 is provided at the rear end of the first pressure-reducing rod 14. A horizontal plate 16 is welded to the middle of the rear side of the outer wall of the electric arc furnace body 1. Threaded pressure-reducing rods 17 are threadedly installed on the left and right sides of the horizontal plate 16. A second pressure-reducing rod 18 is slidably provided inside the threaded pressure-reducing rod 17. The bottom of the buffer ring 15 contacts the upper part of the second pressure-reducing rod 18. A spring 19 is wound around the second pressure-reducing rod 18, and the top end of the spring 19 is connected to the second pressure-reducing rod. On the 18th, the bottom end of the spring 19 is connected to the top of the threaded pressure reducing rod 17. The control box 20 is provided on the front side of the outer wall of the electric arc furnace body 1. The control box 20 is electrically connected to the first hydraulic cylinder 11. The short mesh 21 is connected to the upper part of the control box 20. The copper tile 22 is installed on the upper rear side of the short mesh 21. The inner wall of the copper tile 22 is in contact with the electrode body 701. The second brake ring 23 is installed on the left and right sides of the top of the limiting plate 601. Up to four second stabilizing plates 26 are spaced apart on the outer wall of the second brake ring 23. The second hydraulic cylinder 24 is connected between the second stabilizing plate 26 and the second brake ring 23. The inner end of the telescopic rod of the second hydraulic cylinder 24 is provided with the second gate plate 25.The inner wall of the second gate 25 is in contact with the electrode body 701.

[0025] The ore material 5 inside the submerged arc furnace body 1 refers to ore + reducing agent + flux, which provides the metal source and creates reduction conditions. The alloy 3 refers to the molten metal liquid layer, which is the final product and needs to be enriched with the target metal. The slag 4 refers to the molten silicate layer, which is used for impurity removal, heat preservation, and conductivity adjustment. Then, the operator first opens the first hydraulic cylinder 11. The contraction of the first hydraulic cylinder 11 will cause the first gate plate 13 to move outward. The first brake ring 10 and the first stabilizing plate 12 provide support. At this time, the operator can place the electrode body 701 between the inner sides of the first gate plate 13. The limiting plate 601 will limit the lower part of the electrode body 701. Then, the operator can control the first hydraulic cylinder 1. 1. Extension: The extension of the first hydraulic cylinder 11 causes the first gate 13 to move inward. When the first gate 13 moves inward and contacts the electrode body 701, it fixes the electrode body 701. Then, the operator needs to control the extension of the large vertical cylinder 7. The extension of the telescopic rod of the large vertical cylinder 7 causes the extrusion rod 8 and the extrusion block 9 to move downward. The downward movement of the extrusion block 9 drives the first brake ring 10, the first hydraulic cylinder 11, and the first stabilizing plate 12 to move downward. The downward movement of the first gate 13 causes the electrode body 701 to move downward. This allows the electrode body 701 to be pressed and released as needed. The molten alloy liquid will then flow from the tap hole. 2. When the operator needs to press and release the next electrode body 701, the operator can retract the first hydraulic cylinder 11 and repeat the above operation. When the operator does not need to press and release the electrode body 701 temporarily, the operator can close the first hydraulic cylinder 11 and the large vertical cylinder 7. In order to buffer the downward pressure of the electrode body 701, when the pressing block 9 moves downward, the pressing block 9 will cause the first pressure reducing rod 14 to move downward. The first pressure reducing rod 14 will cause the buffer ring 15 to move downward. When the buffer ring 15 moves downward to contact the second pressure reducing rod 18, the buffer ring 15 will cause the second pressure reducing rod 18 to adaptively reduce the pressure on the thread. As the rod 17 slides within the coil, the spring 19 adapts by deforming and resetting, thus buffering the downward pressure on the electrode body 701. When the pressing block 9 moves upward, it causes the first pressure-reducing rod 14 to move upward, which in turn causes the buffer ring 15 to move upward. When the buffer ring 15 moves upward and stops contacting the second pressure-reducing rod 18, the spring 19's resetting action causes the second pressure-reducing rod 18 to adaptably slide upward and reset within the threaded pressure-reducing rod 17. Operators can use the control box 20 to direct a large current from the short network 21 to the copper tile 22, which then feeds electricity to the electrode. Simultaneously, the copper tile 22 itself must also dissipate heat, provide clamping, and withstand high temperatures.The operator can also open and close the first hydraulic cylinder 11 through the control box 20. To further slow down the pressing and releasing speed of the electrode body 701, the operator can open the second hydraulic cylinder 24. The retraction of the second hydraulic cylinder 24 will cause the second gate 25 to move inward. When the second gate 25 moves inward to contact the electrode body 701, the cooperation of the first gate 13 and the second gate 25 can further slow down the pressing and releasing speed of the electrode body 701. When the operator does not need to press and release the electrode body 701 temporarily, the operator controls the second hydraulic cylinder 24 to retract. At this time, the second gate 25 will move outward to reset, and then the operator needs to close the second hydraulic cylinder 24.
