摘　　要：通过改变精炼过程造渣工艺,减少Al和铝矾土的加入量达到控制钢中夹杂物形态的目的。试验结果表明,对于钢帘线的精炼,最有效控制夹杂物形态的渣是硅灰石或其它成分与硅灰石的混合物。采用新的炉渣精炼工艺,钢水纯净度明显改善。The inclusion morphology is controlled by changing slag formation and reducing the added quantity of Al and bauxite in refining process. The results demonstrate that the most effective method to control the inclusion morphology is adding wollastonite or the mixture of wollastonite in refining process of steel cord. The cleanliness of molten steel has been greatly improved after adopting new slag refining process.
