摘要
目前评估铸坯夹杂物水平的主要依据是夹杂物的面积(体积)分数。借鉴现有的国内外标准,制定了两个评价铸坯夹杂物的指标:纯净度指数和级别数。应用结果表明:这两种指标很好地反映了铸坯夹杂物的含量及其对产品质量的影响程度,如304不锈钢磨砂板的合格率。
Evaluating the content of casting slab inclusion mainly depends on the area （volume） percent of inclusion at present. According to the standards in the world, two indices for evaluating casting slab inclusion were established, i.e. index of purity and rating number. The application showed that the two indices reflect the content of casting slab inclusion and the inclusion influence on the quality of steel, such as the percent of pass of 304 stainless steel grinding plate.
