新型水溶性淬火剂PM121-200T冷却性能及淬火工艺性能

Cooling and Quench Processing Property of New Hydrotropic Quenchant PM121 200T

介绍了新研制的水溶性淬火剂ＰＭ１２１－２００Ｔ。测定了其物理性能及不同浓度和不同温度下的冷却性能。对不同浓度下的淬火工艺性能也进行了研究。结果表明，该淬火剂具有一系列的优点，易溶于水，无毒、无味，淬火时无烟气、无污染，对工件不腐蚀，长期使用不变质、不老化，适用于各类结构钢件的淬火及感应加热冷却。淬火后硬度均匀，变形及开裂倾向小，生产应用效果良好。

A new kind of hydrotropic quenchant PM121 200T is introduced.Its physical and cooling properties in various consentrations and temperatures are measured,and its quench processing properties are experimental studied.The quenchant has many advantages,such as apt to dissolve in water,non toxic,smellless,and smokeless and non pollutant in quenching processing.It doesn’t corrode pieces,deteriorate and age in long time use.It is suitable for use in quenching and cooling of induction heating of plenty of structural steel parts.The quenching hardness distributes homogeneously,and the tendency of deformation and crack is very small.The quenchant is highly effective in application.
