Abstract

1. Electric furnace, in particular a direct-current arc furnace for melting metals, with at least one bottom electrode (7a, b, c, d) which is cooled on its side facing away from the interior of the furnace vessel, characterized in that the ratio of the cross-section of the bottom electrode (7a, b, c, d) in the furnace vessel bottom (4) to the cross-section in the furnace hearth area (16) is selected to be greater than 1.4 : 1, preferably 2 : 1.
