The influence of the height of the slag layer on the thermal loads on the watercooled panels of the walls of arc steel-making furnaces was investigated. The fluxes of thermal radiation from arcs to water-cooled wall panels are maximum when the arcs are not buried and the atmosphere of the furnace is transparent. With an increase in the height of the slag layer and the absorption capacity of the furnace dust and gas atmosphere, the thermal loads from the arcs on the water-cooled wall panels decrease and reach a minimum when the arcs are completely immersed in the slag and the maximum absorption coefficient of the furnace dust and gas atmosphere.
