doi:10.13251/j.issn.0254-6051.2023.07.049

Abstract

Abstract: 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.

Key words: customized strength, contact heat transfer, heat treatment, selected cooling equipment
