摘要
钢铁冶金现场的连铸铸坯表面温度是重要的工艺参数，针对铸坯表面温度难以测量，研究一种前置反射器与多波长结合红外辐射测温方法，该方法分别建立有反射器和无反射器的多波长辐射能量方程，在线求解被测铸坯表面的发射率和铸坯表面温度。利用蒙特卡洛方法建立铸坯表面的多层模型和光波的多次反射一吸收的仿真模型，模型分析表明该方法可实现准确的铸坯表面温度测量。
The surface temperature of casting slab is a virtual parameter in metallurgy field. So, based on reflector- preceded and multi-wavelength, a method to dealing with the difficulty in surface temperature measurement of casting slab is put forward. On the premise of reflector-preceded and non reflector-receded, the method establishes the radiation energy equations, works out the emissivity and temperature in the equations. As well, the multilayer modeling of casting billet surface and muhiple reflection-absorption process modeling by Monte-Carlo method are built. Finally, the ansysis result of the models shows that the method can measure the casting billet surface temperature accurately.
