加热温度及加热速度是感应加热的最基本的工艺参数,它直接决定钢的相变过程和淬火后的组织,是提高和稳定高频表面淬火工艺质量的重要保证。本文根据实践探讨了制定高频热处理工艺时的加热温度及加热速度的计算方法和淬火温度的选择。1.高频感应加热速度的确定高频感应加热速度很快,在相变区内可达50～500℃/s,甚至更高。高频感应加热的关键依据是磁性转变点A_2(或称居里点)和A_2点以上的平均加热速度V_1,以及A_(c3)点。高频感应加热是由交变电磁感应产生涡
Heating temperature and heating rate is the most basic induction heating process parameters, it directly determines the phase transformation of steel and quenched after the organization is to improve and stabilize the high-frequency surface hardening process an important guarantee of quality. In this paper, according to the practice of the development of high-frequency heat treatment process heating temperature and heating rate of the calculation method and the choice of quenching temperature. 1. Determination of high-frequency induction heating rate High-frequency induction heating rate is very fast, up to 50 ~ 500 ℃ / s, even higher in the phase transition zone. The key basis of high-frequency induction heating is the average heating rate V_1 and A_ (c3) of magnetic transition point A_2 (or Curie point) and above A_2 point. High-frequency induction heating is generated by alternating electromagnetic induction vortex
