ABSTRACT:
Disclosed is a process and apparatus for recovering high temperature heat normally lost from materials that have been processed at high temperature, and for transferring this heat directly to materials about to be processed. The apparatus comprises a tunnel having an infrared radiation reflective interior surface through which cool incoming and hot exiting workpieces pass. The cross-sectional shape of the tunnel is elliptical, and the workpieces are moved along focal lines so that radiation emitted from hot workpieces is reflected at the interior surface, directed to cool workpieces, and absorbed. A furnace suitable for subjecting a workpiece to a controlled thermal cycle is also disclosed.
