Within an insulated furnace chamber, a blower circulates heated gasses axially through a cylindrical rotary retort by way of large holes in opposite ends of the retort. A baffle wall near the blower directs the gas flow in the proper direction. An inlet in the entrance end of the retort opens to the exterior of the furnace for introducing the parts to be heated, and a guide within the retort prevents the parts from falling through the forward gas circulation holes. The holes in the discharge end of the retort cooperate with a chute in the wall of the furnace to serve as discharge holes for the heated metal parts.
