多波长型温度计的开发平本一男等１．前言在薄钢板生产过程中，连续热处理炉内钢板温度的测量和控制对保证产品质量是极为重要的。由于辐射温度计能作非接触的温度测量，故被广泛使用。但因钢板表面的组成、粗糙度以及氧化状况等使得辐射率发生变化，所以不一定能获得满意... Multi-wavelength thermometer development of a flat and so on 1. Preface In the process of sheet steel production, the measurement and control of steel sheet temperature in the continuous heat treatment furnace is very important to ensure the product quality. It is widely used as a radiation thermometer for non-contact temperature measurement. However, due to the composition of the steel surface, roughness and oxidation conditions make the emissivity change, it may not be satisfied with the ...
