HEAT PROCESSING SYSTEM AND HEAT PROCESSING METHOD

摘要

The purpose of the present invention is to provide a heat processing system and a heat processing method that are capable of cooling the inner peripheral surface side of a workpiece, in addition to heating the outer peripheral surface side of the workpiece and cooling the outer peripheral surface side of the workpiece, and are also capable of uniformly and continuously cooling the inner peripheral surface side of the workpiece. Said system has: a conveyance device that conveys a hollow cylindrical workpiece (11); an induction heating device (16) that heats the hollow cylindrical workpiece (11) from the outer peripheral surface side; a cooling device (17) that cools the hollow cylindrical workpiece (11) from the outer peripheral surface side; a discharge-side injection device (22N) and an intake-side injection device (21N) that inject a cooling medium towards a cooling range on the inside peripheral surface of the hollow cylindrical workpiece (11), from tip sections; a movement device (22) for the discharge-side injection device that causes the discharge-side injection device (22N) to move; and a movement device (21) for the intake-side injection device that causes the intake-side injection device (21N) to move.
