42 CrM o4钢锻辗齿圈的调质处理

摘要

通过改进调质工艺，使用8％～10％的无机水基淬火液，改进淬火冷却工艺参数，解决了42CrMo4钢齿圈淬火开裂的问题。%By improving the tempering and quenching process , 8%~10%of inorganic water-based quenching liq-uid is used to improve the quench cooling process parameters and solve the crack problem during 42CrMo4 steel gear ring quenching .
