ABSTRACT:
A continuous furnace for metal slabs in which the side walls of the furnace each include a lower portion extending upwardly from the floor of the furnace and an upper portion extending from the lower portion to the roof of the furnace. The upper and lower portions are shaped so that tangents to the inner surface of the upper portion form an angle of at least 90.degree. with respect to the upper planar surface of the slab while tangents to the inner surface of the lower portion form an obtuse angle with such planar surface to minimize the reflection of heat to the slab to the side walls.
