一、引言在对我所热处理炉实现微机温度群控的同时,我们设计了对不同钢种及不同炉号钢样的淬火温度进行自动选择的功能。完成了由经验选择淬火温度向科学选择的过渡。为解决这一问题,做过多种偿试,最后,依据多元回归理论,并在计算机上进行大量的分析、计算,获得了比较圆满的数学模型。对该模型编程以后,工作人员只要输入钢样 I. INTRODUCTION While controlling the temperature of the microcomputer in our heat treatment furnace, we designed the function of automatically selecting the quenching temperature of the steel samples of different steel grades and different furnace numbers. Completed by the choice of quenching temperature to the scientific choice of the transition. In order to solve this problem, many attempts have been made. Finally, based on the multiple regression theory, a large number of analyzes and calculations are conducted on the computer to obtain a more complete mathematical model. After programming the model, the staff simply enters the steel sample
