摘要 对熔融金属在线控制技术的进展进行追溯,并对专用于钢铁工业领域在线分析的未来技术进行预测。对于炼钢车间钢水的成分,随着更多具体条件的确定,将会对这些方法进行更为详细的探讨。作为钢液取样之后的传统熔融钢水在线分析,新的迷你光谱仪的性能开创了新的使用方法,在炼钢过程中的每一步,专用设备用于具体分析。钢水的直接分析一直是钢铁制造商所寻求的终极控制形式,在一个很长的时期内,使用了多种方法进行分析,并且得到国内或者国际上一些学者的支持。由冶金研究中心(CRM)开展的在工业高炉进行的工业测量活动开启了在液态铸铁中硅、锰和碳元素的连续监测。通过使用简洁和自动的LIBS传感器能够直接测量温度及化学成分,这开启了直接钢液分析的方法。 This paper aims to trace the evolution of the online control of molten metal~ the author will forecast the future methods devoted to on site analysis in the field of the steel industry. It will be more precisely discussed the methods that more specifically allow determining, on steel shop floor the com- position of molten steel. As concern conventional at line analysis of molten steel after liquid steel sam- pling, the performance of the new mini spectrometers opens the way to use, at each step of the steel making process, dedicated device devoted to specific analysis. Direct analysis of molten steel has al- ways been sought as the ultimate form of control for steelmakers. For very long period, a variety of approaches have been enabled and supported by national or international authorities. The industrial measurement campaigns conducted by CRM group at industrial blast furnace opened the way to the continuous monitoring of silicon, manganese and carbon concentrations on liquid cast iron. By using compact and autonomous LIBS sensor able to directly measure the temperature together with the chemical composition the way to the direct liquid steel analysis is now opened.
