摘　　要：对加热炉内钢坯内部温度场模拟计算的传统方法是首先通过炉温推算出钢坯表面温度,进而再推导出来的。实际应用中,多种环境变化及燃料热值波动等因素都可能会造成较大的误差。采用比色测温方法,直接获取加热炉内钢坯表面温度,再建立钢坯加热过程的传导模型,得出的结果更为合理精确,避免了由炉温推算钢坯表面温度所带来的误差。The traditional simulation of billet internal temperature field is to derive from billet surface temperature calculated from furnace temperature. In practice, various factors such as environmental changes and fluctuations in fuel calorific value may cause considerable errors. We used colorimetric temperature measurement to directly take billet surface temperature in furnace, and then create the conduction model of billet heating process, which produced more reasonable and accurate results and avoided errors in calculation of billet surface temperature from furnace temperature.
