Abstract

The invention relates to a submerged arc furnace which comprises a furnace shell (1) and a smoke hood (2) arranged on the furnace shell (1), wherein a feeding system (4) is arranged on the smoke hood (2), an air injection system (5) is further arranged on the smoke hood (2), the air injection system (5) is connected into the feeding system (4), smoke guiding-out systems (3) are further arranged on the smoke hood (2), and three electrodes (6) are arranged at the center of the smoke hood (2). The smoke hood (2) is in a regular hexagon shape, exhaust ports (21) are formed in three non-adjacent edges of the smoke hood (2), and the smoke guiding-out systems (3) are all connected to the exhaust ports (21). Side plates (23) and a lifting device for lifting a smoke hood door (22) which is arranged between the side plates (23) in a sliding manner are arranged at two ends of the other three sides of the smoke hood (2). According to the submerged arc furnace, it is convenient to feed, and a cover can be better opened.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a submerged arc furnace. Background technique [0002] Submerged arc furnace is also called electric arc furnace or resistance electric furnace. It is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. However, the existing submerged arc furnace has a complex structure design, inconvenient feeding, and a huge amount of feeding. Manual feeding can no longer meet the needs of production. On the other hand, it is difficult to open the lid of the existing submerged arc furnace. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the ...
