A vessel for handling a heated substance such as molten materials, and a method for cooling such a vessel, the vessel having fluid cooled containment means comprising inner and outer walls defining a space therebetween; an inlet into the space for a pressurized fluid coolant; means for spraying the coolant against the inner wall to maintain a desired temperature at the inner wall; an outlet for removing the spent coolant; and means for establishing and maintaining a pressure differential between the space and the coolant outlet to force the spent coolant out of the space through the outlet. The preferred embodiment of the invention is utilized as a roof or side wall for a metallurgical vessel, for example, an electric arc furnace.
