本文介绍了大型汽轮机低压转子在适当的热处理条件下,使用计算机预测被处理材料的机械性能的方法.试验表明,被处理材料各位置的机械性能可由淬火时的冷却速度、回火方法及含碳量所组成的一次式求得.在这一结果的基础上,我们根据热处理材料的形状及各种机械性能要求,建立了通过对大型锻钢件热处理过程进行计算模拟,以预测其机械性能的CAHT(Computer Aided Heat Treatment)系统.实际应用的结果说明,该系统是有效的,
In this paper, the method of predicting the mechanical properties of materials to be treated by low-pressure rotors of large-scale steam turbines under proper heat treatment conditions is shown.The results show that the mechanical properties of each position can be controlled by the cooling rate during quenching, Based on this result, we set up a model to simulate the heat treatment process of large forgings based on the shape and mechanical properties of heat-treated materials to predict their mechanical properties CAHT (Computer Aided Heat Treatment) system.The results of practical application show that the system is effective,
