一、引言 在工业生产中,尤其是在钢铁工业,温度控制是非常重要的。例如,感应炉加热钢坯时,就需要小孔径的高温计,现已研制成功使用光纤的辐射高温计,该高温计具有传感头可互换的特点,采用了根据双波长辐射计算温度的新算法,而不是惯用地那种根据金属发射率的改变来计算温度的方法。 I. Introduction In industrial production, especially in the steel industry, temperature control is very important. For example, induction billet heating billet, you need a small aperture pyrometer has been successfully developed the use of optical fiber radiation pyrometer, the pyrometer has a sensing head interchangeable features, based on the use of dual-wavelength radiation temperature calculation of the new Algorithm, rather than the usual one that calculates the temperature from the change in metal emissivity.
