Document Type and Number:
WIPO Patent Application WO/2016/002421
Kind Code:
A1
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 increased, during quenching of the inner circumference of the cylindrical workpiece. The present invention has: rotating devices (18, 19) that rotate the cylindrical workpiece (11); holding members (181, 191) that hold the cylindrical workpiece (11) at a prescribed position; a heating member (16) that heats the cylindrical workpiece (11) from the inner circumferential surface side; a cooling device (17) that sprays cooling fluid and cools the cylindrical workpiece (11) from the outer circumferential surface side; and a spraying device (34) provided at a position separated from the cooling device (17) and which sprays the cooling fluid.
