新造渣剂在转炉溅渣护炉上的研究与应用

莱钢炼钢厂采用轻烧镁块代替白云石进行造渣，使炉渣中（MgO）稳定在9％-10％，比用轻烧白云石炉渣（MgO）含量提高了2％-3％左右，满足溅渣工艺要求，提高了溅渣护炉效果，有极大的推广价值。

The steel-making plant of Laiwu Steel Corporation used caustic-burned Magnesite lump to slag replaced with the caustic-burned dolomite, which stabilize the percent of MgO in slag with 9% - 10%. This may increase the MgO percent with 2% - 3% than that in dolomite. This can meet the process of slag splashing to protect the converter, make a rapid progress in slag splashing and can be popularized.
