研究高碳钢小方坯内部各元素的偏析程度以及易偏析元素的分布情况。通过试验分析得出,易偏析元素为 C、P、S,在小方坯内部的几何中心点偏析最高,内弧侧较外弧倒易出现正偏析,两侧元素波动不大。
The segregation of various elements in high carbon steel billet and the distribution of easily segregated elements were studied. The experimental analysis shows that the easily segregated elements are C, P and S, and the segregation is the highest at the geometrical center of the billet. The segregation of the inner arc is more prone to positive segregation than that of the outer arc, with little fluctuation on the two sides.
