摘　　要：为了降低IF钢浇铸过程中Als的损失,提高铸坯质量,改进了中间包吹氩工艺,增加中间包的吹氩面积并采用预制密封件。结果表明,降低了IF钢Als损失量,Als损失量≤0.008 0%的比例从40%提高到76%。In order to reduce the loss amount of Als in molten IF steel during casting and in- crease the quality of a strand, such measures as improving the argon blowing technology in tundish, increasing the range of argon blowing in tundish and using the prefabricated sealing ele- ments were taken. The results of application showed that the loss amount of Als in molten IF steel was reduced and the loss amount of Als with the percentage less than 0.008 0% was increased to 76% from 40%.
