日本专利昭47—46642号介绍了一种工艺简单,不需要在钢锭模内添加脱氧剂修正脱氧而生产半镇静钢钢锭的方法.半镇静钢水的脱氧工艺为:在将钢水注入钢锭模内之前,向钢水中加入含50～85%Mn,2～5%Si 和0.02～0.5%Ti 以及0.5～5.0%Al 的合金,使钢水脱氧,并借以将钢中Mn 量调至0.35～1.2%的范围内。 Japanese Patent No. Sho 47-46642 discloses a method for producing a semi-killed steel ingot which has a simple process and does not require deoxidizer to be added in a steel ingot mold to correct deoxidation The deoxygenation process of semi-killed molten steel is as follows: before the molten steel is injected into the ingot mold , Adding an alloy containing 50-85% Mn, 2-5% Si, 0.02-0.5% Ti and 0.5-5.0% Al to the molten steel to deoxidize the molten steel and thereby adjust the amount of Mn in the steel to 0.35-1.2% Range.
