Abstract
The present invention addresses the issue of providing a heat treatment system and a heat treatment method whereby the inner circumference of a cylindrical workpiece can be reliably cooled regardless of the dimensions or shape of the workpiece and productivity can be improved, during quenching of the inner circumference of the cylindrical workpiece. The present invention has: rotating devicesthat rotate the cylindrical workpiece: holding membersthat hold the cylindrical workpieceat a prescribed position; a heating memberthat heats the cylindrical workpiecefrom the inner circumferential surface side; a cooling devicethat injects cooling fluid and cools the cylindrical workpiecefrom the outer circumferential surface side; and a injecting deviceprovided at a position separated from the cooling deviceand which inject the cooling fluid.
