摘　　要：利用激光诱导击穿光谱技术实现氩氧精炼炉内硅元素含量的在线分析,通过大量实验和现场测试确定硅元素的测量谱线,并建立定标模型实现硅含量的定量分析。实验表明,该分析方法分析速度快,准确度及灵敏度能够满足过程控制及终点控制要求。The silicon content is analyzed on-line by the method of laser-induced breakdown spectroscopy in the process of argon oxygen deearburization. The characteristie line of silicon is confirmed first by sufficient experiments and veracious on-site tests and then a calibration model is set up whose aim is to achieve quantitative analysis of silicon. The experiment shows that the method has virtues of rapidness, accuracy and sensitivity, and can meet the demands of process control and end point control properly
