针对陶瓷制品烧结过程中的在线温度检测,引入了比色测温方法。根据比色测温的原理构建了比色测温系统。提出了系统关键参数比色波长、发射/转化率的确定方法,其中重点分析和推导了波长与能量、灵敏度的关系。根据陶瓷烧结过程特点搭建了样机,并进行了测试,结果表明在1 300 K～2 000 K范围内测温误差小于10 K。

The method of chromatic thermometry was introduced into the on-line thermometry of ceramic sintering. The thermometry system was designed according to Planck law. The calculation methods of key parameters, such as wavelength, emissivity, rate of conversion, were presented. The relation between wavelength and energy/sensitivity was comprehensively analyzed. The prototype was set up and tested according to the characteristics of ceramic sintering process, and the results indicated the metering error was less than 10 K during 1 300 K～2 000 K.
