Abstract
In order to reduce the power loss of a direct current arc furnace the furnace vessel is only partially cooled in the region situated above the melting zone. A first cooling device is provided on a top edge of the vessel. A second cooling device is provided at the height of a slag line. The region of a vessel wall situated therebetween and facing the interior of the vessel above the slag line consists essentially of refractory material.
