INFLUENCE OF CAPACITANCE, DISTANCE FROM ARCS TO WALLS ON THE EFFICIENCY OF ARCS AND ELECTRICITY CONSUMPTION IN EAF
Keyword(s):
The influence of the distance from the arc to the walls in the entire nomenclature row of arc steelmaking furnaces with a capacity of 0.5 to 120 tons on the efficiency of the arcs and the specific consumption of electricity in the furnaces was investigated. In low-tonnage EAF, the arcs are close to the walls and the efficiency of the arcs is small and amounts to 30…35 %, and the specific electric power consumption for melting is 650 kWh/t. In heavy-duty EAF, the arcs are located far from the walls, the arc efficiency is 46…49 % in the absence of a slag layer, and the specific electric power consumption for melting is 375…385 kWh/t.
