Description

Technical Field

[0001] This utility model relates to the field of submerged arc furnace technology, specifically to an integrally formed furnace eye chute structure for carbon ferrochrome smelting. Background Technology

[0002] A submerged arc furnace, also known as an electric arc furnace or resistance furnace, is mainly used for the reduction and smelting of ores, carbonaceous reducing agents, and solvents. It primarily produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and ferrosilicon-manganese alloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. The transformer used in a submerged arc furnace provides continuous and stable load, low impedance voltage, a large number of voltage regulation stages, small stage differences, and strong overload capacity.

[0003] The existing Chinese utility model patent with publication number CN220708095U discloses a prefabricated furnace nozzle component, including a prefabricated body with a semi-cylindrical structure. The top outer wall of the prefabricated body has a U-shaped mounting groove. An impact plate is engaged with the inner wall of the mounting groove. Rectangular grooves are formed on both sides of the inner wall of the mounting groove, and bidirectional screws are rotatably connected to the inner walls of both rectangular grooves. Two threaded sleeves are screwed to the outer walls of the two bidirectional screws. Connecting plates are rotatably connected to the outer walls of the four threaded sleeves, and two locking blocks are rotatably connected to one end of each of the four connecting plates. The two locking blocks slide and clamp onto the inner walls of the two rectangular grooves. This utility model overcomes the shortcomings of the prior art by using an integrally formed prefabricated component to replace the traditional furnace nozzle chute. The furnace nozzle chute prefabricated component does not need frequent replacement, saving maintenance and usage costs.

[0004] Although the aforementioned prefabricated nozzle component solves the problem of frequent replacement and high maintenance costs associated with traditional prefabricated nozzle chutes by replacing them with an integrally formed prefabricated component, the device uses a bidirectional screw located inside the prefabricated component to rotate and move the clamping block. However, the bidirectional screw is located inside the prefabricated component and is prone to expansion due to high temperatures, which can cause rotation difficulties. Furthermore, prolonged use can lead to stripping of the screw threads, thus affecting the clamping and fixing of the impact plate. Utility Model Content
