The distributions and characteristics of non-metallic micro-inclusions of GCr15 and SS400 casting slabs in process of BOF-LF-VD-CC were analyzed by metallographic volume ratio method,in virtue of tracer method and electronic microscope.

• 借助扫描电镜和示踪法,利用金相学体积率法对BOF-LF-VD-CC流程生产的GCr15方坯连铸轴承钢和SS400板坯连铸中碳钢中非金属显微夹杂物的类型、特点、数量和分布进行了分析。
