采用二次正交回归方法设计了以CaO-Al2O3为基本组成,并添加MgO、BaO、CaF2、Na2O等组分的精炼渣;通过系统的实验室研究,建立了硫分配比与精炼渣组分百分比含量关系的数学模型;确定了脱硫精炼渣的最佳组成。采用该精炼渣进行脱硫试验,可使钢中硫含量降至0.000 4%。
The quadratic orthogonal regression method was used to design the refining slag with CaO-Al2O3 as the basic component and MgO, BaO, CaF2, Na2O and other components added. Through the systematic laboratory research, the sulfur distribution ratio and refining slag component The percentage of the relationship between the mathematical model; determine the best desulfurization slag composition. The use of the refining slag desulfurization test, the steel can reduce the sulfur content of 0.0004%.
