Abstract: A pipe coil is heated in the furnace of a heat treatment apparatus, The oil adhered to the inside of the pipe is vaporized by this heating, In this state the oil removing gas is fed at one end into the pipe which gas is in the high temperature enough to maintain the vaporizing condition of the oil. The vaporized oil within the pipe is discharged by the feeding of the gas at the other end of the pipe while the oil is in the vaporized state,

Abstract: A process for hardening a plurality of holed flat parts. The holed flat parts are heated by inserting a cantilever hanger into the holes of the holed flat parts to support them in vertical positions within a furnace. The holed flat parts are then removed from the hanger by inserting a moving fork into the holes of the holed flat parts and moved to a cooling section while being supported in the vertical positions on the moving fork. Then, the holed flat parts in the vertical positions are quenched in the cooling section by blowing a gas downward to them. Also disclosed is an apparatus for practicing the holed flat part hardening process. The apparatus comprises: a continuous furnace; a plurality of stands arranged in the continuous furnace and each having a cantilever hanger; a loader including a moving fork for hanging the holed flat parts on the hanger; an extractor including a moving fork for extracting the holed flat parts from the hanger; and a cooling section for blowing a gas downward to the holed flat parts supported by the moving fork of the extractor, to quench the holed flat parts.
