Description
Technical Field
The utility model relates to the field of steelmaking electric arc furnaces, in particular to a movable cover structure for a steelmaking electric arc furnace.
Background
At present, the main stream electric furnace dust removal in China generally adopts a combination of a movable closed cover and a top suction cover. The top suction hood is arranged on the roof of the factory building. The closed cover mainly comprises a fixed cover body and a movable cover body. The furnace back and the two sides of the furnace are fixed cover bodies, and the operation side in front of the furnace is a movable cover body.
Under the working condition of normal smelting after charging of the arc furnace, the top suction hood of the roof does not work and the smoke dust is trapped by the closed hood. When the electric arc furnace feeds and discharges steel, the furnace cover is in an open state, the closed cover does not work, and smoke dust generated by the electric arc furnace is captured by the top suction cover of the roof.
However, when the arc furnace works, smoke dust can be diffused and scattered into a workshop on one hand in the process of lifting the smoke dust from the furnace to the top suction hood. On the other hand, the smoke dust can be blown off by the cross wind of the workshop, and the top suction cover is difficult to capture. The scattered smoke seriously pollutes workshops and surrounding environments, and endangers the health of operators.
