Abstract
A water-cooled roof comprises a roof ring of a circular cross section, and the ring supports a box-shaped structure welded from metal plates. The structure consists of two portions, a central portion in the form of a hollow disc and a peripheral portion in the form of a hollow ring. The joint between the central and peripheral portions is packed with a gasket of an electric-insulating material. The roof is lined with a refractory material from the side of the furnace. The endurance of such a roof exceeds that of a conventional roof 25 - 30 times.
