摘要/Abstract

摘要： 针对现有射流式定制强度热处理选区冷却设备处理的工件存在过渡区宽度宽、冷却边界不清晰等问题,通过系列试验验证和结构优化设计,研发了接触式定制强度热处理选区冷却设备。结果表明,该设备通过镶块与板料接触传热的方式,可以大幅度减小过渡区宽度(30 mm→10 mm),冷却边界清晰,能更好地满足特殊软区的需求。

关键词: 定制强度, 接触传热, 热处理, 选区冷却设备

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
