摘要
Abstract
The effect of refining slag on inclusions was studied from two aspects, the activity of A1203 and the composition of inclusions. The activity of A1203 in a CaO-A1203-SiO2-MgO（8% ）-CaF2 （8%） slag was calculated by the thermodynamic software Factsage, and the influence of slag basicity and （MgO） content on the activity of A1203 were analyzed. When the slag basicity increa- ses from 1.0 to 2. 0, the activity of A1203 in the slag decreases rapidly, and when the slag basicity increases from 2.0 to 3. g, the activity of A12 O3 has little change. There is little difference in the activity of A1203 between the slags with （MgO） mass fractions of 5% and 8% , and [ A1]l can be easily reduced into molten steel from the slag with high basicity. Many brittle inclusions containing MgO were found in wire rods with the high basicity refining slag, and by analysis the most appropriate basicity is 2.5 to 3.0.关键词
