Meanwhile, the primary dendrite spacing is decreased and the secondary dendrite branches are restrained.
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。
Within specified limits, the primary dendrite spacing will be extended and the macrostructure defect will be obviously decreased in continuous cast billet with the increase of silicon content.
指出在一定限度内，随硅含量增加，铸坯的一次晶间距加宽，各类低倍组织缺陷大大减少。
