Description

Technical Field

[0001] The present application relates to the field of submerged arc furnaces, and in particular to an electrode structure of a submerged arc furnace. Background Art

[0002] Submerged arc furnace is also called arc furnace or resistance furnace. It is mainly used for reducing smelting ore, carbonaceous reducing agent and solvent and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon-manganese alloy and other ferroalloys. It is an important industrial raw material in the metallurgical industry and a metallurgical equipment for chemical raw materials such as calcium carbide. It is mainly composed of furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressing and lifting system, loading and unloading system, gripper, burn-through device, hydraulic system, submerged arc furnace transformer and various electrical equipment.

[0003] Announcement No. CN 216905362 U discloses a vertical lifting guide mechanism for an electrode of an electric arc furnace. When the electrode needs to be fixed at a certain height, the electrode body only needs to be driven to move in the vertical direction by a driving mechanism so that the electrode body moves along a guide column. When the electrode body moves to an applicable position, the staff only needs to pass the limit piece through the guide column and plug it into the guide block so that the electrode body is fixed at an applicable position, which is convenient for fixing the electrode body.

[0004] However, there are some defects in the above scheme: in the above scheme, the limiter needs to be manually inserted through the guide column and plugged into the guide block, and multiple components need to be manually fixed one by one, which not only wastes time and is inefficient, but also is dangerous to manually operate on the ore furnace.

[0033] Among them, a guide groove 112 is opened in the support frame 110, and a guide slider 121 is set at the end of the movable plate 120. The guide slider 121 is slidably set in the guide groove 112. By setting the guide slider 121 to slide in the guide groove 112, it is used to guide the movable plate 120 to move up and down stably in the support frame 110.

[0034] Specifically, a guide wheel 123 is provided at the end of the guide slider 121, and the guide wheel 123 contacts the inner wall of the guide groove 112. By setting the guide wheel 123 to contact the inner wall of the guide groove 112, it is beneficial to support the movable plate 120 to move stably in the guide groove 112, thereby ensuring the stable rise or fall of the electrode body 130 below.

[0035] In this embodiment, the driving member 150 includes a winding roller 151, a traction rope 152 and a second motor 153. The winding roller 151 is installed on the top of the support frame 110, and the second motor 153 is installed on the top of the support frame 110 and is transmission-connected to the winding roller 151. The two ends of the traction rope 152 are respectively connected to the winding roller 151 and the movable plate 120.

[0040] It should be noted that the positioning block 240 and the fixed cylinder 230 are both rectangular, and the inner wall clearance of the positioning block 240 and the fixed cylinder 230 is matched. By setting the rectangular positioning block 240 and the fixed cylinder 230, the positioning block 240 slides in the fixed cylinder 230, limiting the rotation of the threaded transmission and guiding its linear movement.
