摘　　要：通过分析一炼钢LD RH CC工艺试制镀锡板连铸坯的夹杂物分布、数量及组成情况 ,了解了冶炼控制技术和相关铸坯质量状况 ,分析得到铸坯厚度方向夹杂物面积较大的分布区域 ,1 3 5 0段面铸坯夹杂物集中在离上表面 80mm左右 ,95 0段面铸坯夹杂物集中在离上表面60mm左右。试验表明夹杂物的平均尺寸小于 60 μm2 ,大部分夹杂物为脱氧产物。By analyzing the distribution,quantity and composition of tin plate CC slab produced by means of LD RH CC of No.1 Steelmaking Plant at Baosteel,the smelting control technology and slab quality are known.The regions with large quantity of inclusion along thickness of slab are found out.The inclusions of the slab with a width of 1350mm and 950mm are concentrated in the regions of 80mm and 60mm from the upper surface respectively.The result shows that the average size of the inclusion is less than 60μm 2,most of them are deoxidization products.Meanwhile,the inclusion distribution situation in the direction of width is also discussed.
