本文研究了大型氧化物夹杂沿钢锭高度的分布,重点考察了钢锭底部夹杂物的类型和在底部等轴晶区内夹杂物的聚积形状,并提出了底部夹杂积聚机理和消除措施。
In this paper, the distribution of large oxide inclusions along the height of the ingot was studied. The types of inclusions in the bottom of the ingot and the shape of inclusions in the equiaxed zone at the bottom of the ingot were investigated emphatically. The mechanism of inclusion at the bottom and the elimination measures were proposed.
