Abstract
A furnace for heating one or more bodies in which heated gas is introduced into the furnace chamber through one or more injectors and are conveyed to the bodies in a manner involving appreciable resistance to gas flow. In a preferred arrangement a continuous metal strip is conveyed through the furnace on a gaseous support cushion, the gas being introduced into the furnace under pressure through injectors which communicate with the lower portion of the furnace. The injectors generate a substantial recirculation of gas within the furnace.
