WIPO Patent Application WO/2022/210868
Kind Code:
A1
Abstract:
In heating step S101, a steel plate is heated and brought into an austenite state. In heating step S101, the entire area of the steel plate is uniformly heated to bring the entire area of the steel plate into the austenite state. In cooling step S102, only a set first area of the steel plate in the austenite state is forcibly cooled (rapidly cooled) within a temperature range in which martensite transformation does not occur. In cooling step S102, a second area other than the first area is cooled naturally, and maintains a state of higher temperature than the first area.
