钢管中频加热温度的红外测量

Infrared Method for Testing the Mid-frequency Heating Temperature of Steel Pipes

介绍了一种非接触式钢管中频加热温度的测量方法,与直接接触式测量方法进行了对比,讨论了影响非接触式钢管中频加热温度的测量方法准确性的因素。结果表明,非接触式钢管中频加热温度的测量方法具有更高的准确性,与接触式测温配合使用、互为补充,增强了测温的可靠性。

In the steel pipes coating processing, direct-touching and un-touching are two methods in testing the steel pipes＇ temperature. And presently the direcvtouching method is mainly used, which is performed by using a tempilstick to get the surface temperature of steel pipes after mid frequency heating. The two methods have their advantages and disadvantages respectively. In this paper, a kind of infrared testing method is introduced and compared with the direct-touching method. The impact factors in testing temperature are discussed. The application results show that this kind of un-touching method can give much more true and precise temperature values of the steel pipes.
