使用PAG类UCON E水溶液作为淬火介质,采用循环控时淬火方法,合理制定淬火冷却控时参数,解决了42CrMo钢中型尺寸锻件及其他中碳合金结构钢工件“油淬不硬,水淬开裂”的问题,工件调质后达到了技术要求的力学性能。
The use of PAG UCON E aqueous solution as a quenching medium, the use of circulating control quenching method, the rational development of quenching and cooling control parameters to solve the 42CrMo steel medium size forgings and other medium-carbon alloy structural steel parts “Oil quenching is not hard, water quenching cracking ”Problem, the workpiece after quenching to meet the technical requirements of the mechanical properties.
