摘要
针对45钢制摩托车曲柄轴颈部位表面高频感应加热淬火冷却一直沿用NaCl水溶液对工件、淬火装置和周围机械加工设备锈蚀严重的问题,通过试验与分析,采用HSLY环保类盐防锈型水溶性淬火介质取代了NaCl水溶液。结果表明,与原传统的NaCl水溶液相比,对工件采用一定浓度的HSLY水溶性淬火介质冷却不仅能够满足该产品的技术要求,而且还具有良好的防锈效果。同时,讨论了影响工件高频感应淬火质量的几个主要因素,并简要介绍了HSLY水溶性淬火介质的特点、使用维护要点和生产应用。
In view of the serious corrosion problems to workpiece, quenching device and surrounding mechanical processing equipment caused by NaC1 solutions in high frequency induction heating quenching cooling of the journal surface of 45 steel motorcycle crank, NaC1 solution was replaced by HSLY environment friendly salt aqueous quenchant. The results show that using a certain concentration HSLY aqueous quenchant can not only meet the technical requirements of the product, but also has a good antirnst effect compared with using the conventional NaCl solutions. At the same time, several main factors affecting the quality of high frequency induction quenching was discussed, and the characteristics, maintenance and production application of HSLY aqueous quenchant were briefly introduced.
