通过确定凝固速度的表达式，定量计算了连铸过程中一次枝晶间距。
Based on the conformation of the solidification rate expression, the quantitative calculation of the primary dendritic spacing in the continuous casting was done.
并且随着对流强度的加大，一次枝晶间距降低，二次枝晶的生长被抑制。
Meanwhile, the primary dendrite spacing is decreased and the secondary dendrite branches are restrained.
探讨了铸坯中一次枝晶间距的变化规律及其“鼓肚”量对枝晶间距的影响。
The variation rule of the primary dendritic spacing in the casting blanks and the effect of the bulge size on dendritic spacing were studied.
