Abstract:
A heat treatment apparatus of one aspect of the present disclosure includes: a feed device that feeds a heat treatment workpiece downstream in a feed direction along a heat treatment workpiece pass-line; a heating device that includes a heating coil disposed downstream of the feed device in the feed direction and encircling the pass-line; a cooling device that is disposed adjacent to the heating coil, downstream of the heating coil in the feed direction, and encircling the pass-line; and a gas supply device that is disposed upstream of the heating coil in the feed direction, directly connected to the heating coil and encircling the pass-line, and that includes a plurality of gas compartments configured by internally partitioning the gas supply device in the feed direction.

Claim (Index 15):
A heat treatment method for a steel workpiece as the heat treatment workpiece when the heat treatment apparatus of  claim 7  is employed, the heat treatment method comprising:\n feeding the steel workpiece into the heating coil in a state in which a non-oxidizing gas is supplied into any of the gas compartments of the gas supply device such that the gas compartment positioned furthest upstream in the steel workpiece feed direction has positive pressure, and such that the gas cloaks a periphery of the steel workpiece passing through the gas compartments; \n heating the steel workpiece with the heating device; and \n cooling the heated steel workpiece with the cooling device.
