本文介绍了为提高冷轧工作辊表面硬化层深度而研究采用的低频感应连续加热淬火及冷处理工艺。鉴于采用中频感应连续淬火热处理,轧辊能得到变形和残余应力都较小的表面硬化层,但与原来的工艺比较,其加热温度和保温时间不足。为弥补上述缺点,采用低频感应连续加热淬火,从而提高了表面硬化层深度。此外,利用其残余应力小的特点,采用相应的冷处理,使硬化层深度提高为原来的2倍。 This paper introduces the low frequency induction continuous heating quenching and cold treatment technology used to improve the surface hardening layer depth of cold rolling work rolls. In view of the continuous induction quenching heat treatment with intermediate frequency induction, the roll can get the surface hardened layer with smaller deformation and residual stress, but compared with the original process, the heating temperature and holding time are not enough. To make up for the above shortcomings, the use of low frequency induction continuous heating quenching, thereby increasing the depth of the hardened layer. In addition, the use of its small residual stress characteristics, the corresponding cold treatment, the hardened layer depth increased to 2 times the original.
