Furnace wall gun swinging device

Abstract

The invention discloses a furnace wall gun swinging device, and belongs to the technical field of metallurgy. The furnace wall gun swinging device comprises a furnace wall gun and a furnace wall gun supporting frame. The furnace wall gun supporting frame is provided with a furnace wall gun swinging cavity. The furnace wall gun swinging device further comprises a swinging mechanism capable of driving the furnace wall gun to swing in the furnace wall gun swinging cavity. The injection covering area of the furnace wall gun in a furnace can be increased through the swinging mechanism, the area of a cold area in the electric furnace is effectively reduced, the smelting period is shortened by sufficiently utilizing chemical energy, and the cost of ton steel is saved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a furnace wall gun swing device. Background technique [0002] In the short-process electric furnace steelmaking, in order to shorten the smelting cycle and save the cost per ton of steel, the effective way is to increase the utilization of chemical energy. Therefore, in recent years, the enhanced oxygen use technology for electric furnace smelting has been continuously developed. Most electric furnaces are equipped with supersonic oxygen lances and carbon lances to input chemical energy, reduce power consumption and smelting cycle. [0003] In the existing technology at home and abroad, the furnace door gun can change the injection point in a large range, but the furnace door gun is limited to the area near the furnace door and cannot reach all parts of the electric furnace, while the carbon oxygen gun on the furnace wall of the electric furnace is fixedly install...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology at home and abroad, the furnace door gun can change the injection point in a large range, but the furnace door gun is limited to the area near the furnace door and cannot reach all parts of the electric furnace, while the carbon oxygen gun on the furnace wall of the electric furnace is fixedly installed in the furnace. On the wall, and the number is limited, so the heating range is small, the cutting of scrap steel is limited, and the efficiency of carbon spraying and slagging is low. There are cold areas and hot areas in the electric furnace. Higher, the scrap steel melts faster, and the cold zone is the area where the carbon-oxygen lance cannot be sprayed. The temperature is relatively low, and the scrap steel melts slowly. For a long time, all electric furnace smelting manufacturers have wanted to solve the cold zone problem of electric furnace smelting
