Abstract

An arc furnace having a space for accommodating charging material, said space being disposed on one side of the furnace vessel and communicating with the interior of the furnace vessel and being disposed at least partly in the region of radiation of the arc of at least one arc electrode. The arc electrode is movable towards and away from the charging material accommodating space, and thereby permits better utilization of the radiant heat generated by the arc.
