摘要：

基于红外热像及比色测温技术的钢水温度检测可以避免钢渣、钢水液面镜面效应等造成的测量误差。文章通过对红外热像的灰度分布特性、波动规律等测算正向辐射概率，并确定最佳采样区域，从而准确获取钢水温度。给出温度变化曲线，提高钢水温度数据测量的准确性和连续性，有利于精密炼钢的实现。

Abstract:

The measurement error caused by steel slag, molten steel surface mirror effect can be avoided by molten steel temperature detection on the basis of infrared thermal imaging and colorimetric thermometry. The temperature of molten steel can be obtained by calculating the forward radiation probability of fluctuation, infrared image gray level distribution and so on, and confirming the optimal sampling area. Giving the temperature change curves of molten steel and improving data accuracy and continuity, are conducive to the realization of precision steel making.

Key words: RH furnace, temperature of molten steel, infrared thermal imaging, image recognition
