一、前言在冶金工业中,为了加强管理和控制,广泛采用了以各种方式利用热能来测温的技术。目前,测温的方法大致分为两种:一种是利用热电偶等的接触式测温法;另一种是利用辐射温度计的非接触式测温法。由于在生产过程中,高温被测物的运动速度非常快。生产过程也越来越复 I. INTRODUCTION In the metallurgical industry, in order to strengthen management and control, technologies that utilize thermal energy to measure temperature are widely adopted in various ways. At present, the temperature measurement methods are roughly divided into two types: one is the use of thermocouple contact temperature measurement method; the other is the use of radiation thermometer non-contact temperature measurement method. As in the production process, the temperature of the measured object’s movement speed is very fast. The production process is getting more complex
