摘要

大型轴承套圈感应表面硬化的热处理模拟是一项具有挑战性的多物理任务。除了确定感应加热的材料和工艺参数外,还必须对淬火过程进行建模,以获得有关表面硬化深度以及轴承套圈残余应力和变形的真实结果。对淬火过程进行建模的一种常用方法是根据部件表面温度确定特定过程的传热系数。该方法用于表征使用改性聚烷基二醇(PAG)型聚合物水溶液的淋浴冷却过程。一个专门设计的测试装置,可以确定淋浴和热样品之间不同距离的传热系数,以及流体相对于重力的不同撞击角度。通过有限元模拟对计算得到的换热系数进行了校核和修正。

Experimental Determination of Heat Transfer using a Polymer Solution Shower during Induction Hardening*
Abstract Heat treatment simulation of inductive surface hardening of large bearing rings is a challenging multi-physical task. Besides the determination of material and process parameters of induction heating, the quenching process must be modelled to obtain realistic results concerning surface hardening depth as well as information about residual stresses and distortions of the bearing rings. A common method to model quenching processes is to determine heat transfer coefficients for the specific process depending on component surface temperature. This method was used to characterize the shower cooling process using an aqueous polymer solution of a modified polyalkylene glycol (PAG) type. A specifically designed test set-up allowed to determine the heat transfer coefficients for different distances between shower and hot specimen as well as for different impingement angles of the fluid relative to gravitation. Additionally, the calculated heat transfer coefficients were checked and corrected by FEM simulations.
