摘　　要：研究了新型水溶性淬火介质与传统无机盐淬火介质对液压支架千斤顶零件热处理性能的影响。结果表明:与传统无机盐淬火介质相比,采用10%KR6480水溶性淬火介质调质处理的30Cr Mn Si和42Cr Mo钢的强度略低,组织更为细小均匀,平均冲击功更高。The influences of the new water soluble quenchant and the traditional inorganic salt quenchant on the heat treatment performance of the hydraulic jack parts were studied. The results show that compared with the traditional inorganic salt quenchant, the strengths of 30CrMnSi and 42CrMo steels quenched and tempered by 10% KR6480 water soluble quenchant are little lower, but the microstructure is finer and more homogenous, and the average impact power is higher.
