感应热处理是一项节能、无污染、少氧化、无脱碳的快速加热技术,并具有容易实现机械化和自动化生产的特点[1],因此多年来一直得到广泛的重视和迅速的发展。众所周知,感应淬火必须设计各种形状感应器,以满足零件各个加热部位的要求,而在某种意义上说,感应器是感应淬火技术的核心。其设计是否合理,制造是否精良,将直接影响零件的加热效果、淬火质量和生产效率。因此,感应淬火的工 Induction heat treatment is an energy-saving, pollution-free, oxidation-free and decarburization-free rapid heating technology, and has the characteristics of easy mechanization and automatic production [1]. Therefore, it has been widely appreciated and rapidly developed over the years. As we all know, induction hardening must design a variety of shape sensors to meet the various parts of the heating requirements, and in a sense, the sensor is the core of induction hardening technology. Its design is reasonable, manufacturing is good, will directly affect the heating effect of parts, quenching quality and production efficiency. Therefore, induction hardening workers
