Contact type customized strength selective cooling equipment for ultra-high strength steel
Chen Jiaheng, Li Xianjun, Luo Ping
In response to the problems of wide transition zone width and unclear cooling boundary in the workpiece treated by the existing jet type customized strength heat treatment selective cooling equipment, a contact type customized strength heat treatment selective cooling equipment has been developed through a series of experimental verification and structural optimization design. The results show that the equipment can significantly reduce the width of the transition zone (30 mm→10 mm) by conducting heat transfer through contact between the insert and the plate, with clear cooling boundaries, and can better meet the needs of special soft areas.
