Abstract
A liquid cooled cover for an electric furnace, wherein in order to lengthen the service life of the thermally highly stressed cover, cooling pipes are located essentially parallel and approximately vertically to the furnace tipping direction at a predetermined distance from each other. The cooling pipes are embedded in a fireproof construction material (57, 57') and constitute its reinforcement. The cooling liquid is supplied and removed exclusively via a cover ring, which is constructed as a cooling liquid distributing conduit in the periphery of the cover and which provided with integrated bypass openings. The composite construction of cooling pipes and fireproof construction material achieves a high thermal and mechanical stability of the furnace cover and the cooling system is largely removed from altering temperature stresses.
