摘　　要：目前钢铁行业常用的测量碳含量的方法为热分析、化学分析和光谱分析法。这3种方法在铁的碳含量及其它元素的测量方面有着较高的测量精度,但其不足之处都是离线式测量,在高度自动化的生产过程中难以满足在线实时测量的要求。现代的AOD炉炼钢,已经采用光强度测量实现了碳含量的在线测量,解决了在线测量的问题。Currently, the measurement methods of carbon content in steel industry are thermal analysis, chemical analysis and spectrum analysis. These three methods have higher accuracy in the measurement of carbon content and other elements in steel, but the inadequacies lies that they are off-line measurement, which can not meet the on-line and real-time measurement requirements in the highly automated production processes. In modern AOD furnaces, we have adopted the method of measuring light intensity to determine carbon content on-line, which solves the problem of on-line measurement.
