1前言欧洲和南非最近新开发的转炉副枪传感器能够同步读取钢水及炉渣的温度与氧活度、钢水液位和渣层厚度。该副枪传感器与专家模型结合使用可精确地预测吹炼终点钢水的碳含量,判断是否直接出钢。该系统可直接测定钢水中磷含量,并可估算转炉装入量,平均每天至少增加一个炼钢炉 1 Introduction The newly developed converter sub-lance sensors in Europe and South Africa are capable of simultaneously reading the temperature and oxygen activity of molten steel and slag, the molten steel level and the thickness of the slag layer. The sub-gun sensor used in conjunction with the expert model accurately predicts the carbon content of the molten steel at the end of the blowing and determines whether the steel is directly tapped. The system can directly measure the phosphorus content of molten steel, and can estimate the amount of converter loading, the average increase of at least one steelmaking furnace
