Abstract

The composition of the dust and gas atmosphere affects the heat transfer in the arc steelmaking furnace. With a significant dustiness of the furnace atmosphere, the heat flux of arcs emitted by them into the free, not filled with charge, space is mainly absorbed by the dustgas medium and carried away from the furnace in the form of heat losses with exhaust gases. In the radiant atmosphere of the furnace, the heat flux of the arcs, radiated by them into the free space, reaches the walls, is absorbed by the water of the water-cooled panels and is carried away from the furnace in the form of heat losses with the cooling water.
