温度串级控制在蠕变试验机上的应用

Application of Temperature Cascade Control to Creep Testing Machine

本文介绍了温度串级控制原理及使用的具体方法,并以其在蠕变试验机高温炉控温中的应用为例,给出了温度串级控制的过程及实现方法,达到了在温度定值控制中温度波动较小的试验要求。

The principle and the specific method of temperature cascade control are introduced in the paper.Taking its application in the temperature control of high temperature furnace of creep testing machine as an example,the process and realization method of temperature cascade control are given,so as to realize the test requirement of less temperature fluctuation in constant temperature control.
