Abstract
An apparatus is disclosed for a spray-cooled roof of a tilting metallurgical furnace having a drain pump. The spray-cooled roof has a hollow metal roof section. The hollow metal roof section has an outer metal covering member, an inner metal base member spaced from and opposite the outer metal covering member, an enclosed space disposed between the outer metal covering member and the inner metal base member, and a spray-cooled system disposed in the enclosed space. An evacuation drain is fluidly coupled to the enclosed space and a pump is integrated into the spray-cooled roof and coupled to the evacuation drain.
