The redistribution of solutes during steel solidification induces macrosegregation ultimately.

摘要固过程的溶质再分配是产生宏观偏析的根本原因。

In the former case,the solute segregation in dendritical austenite more severe,and there were lumps of distortion inclusion.

前者枝晶奥氏体内溶质偏析大，有畸变夹杂团块。

Although PM has solved the problem of carbide segregation and crassitude fundamentally, it has complicated technics and extortionate cost, so restricts its application.

粉末冶金虽然从根本上解决碳化物偏析和粗大的问题，但其工艺复杂，成本过高，应用受到限制。

To reduce extra loss of energy, erase sperromagnetism, and prevent spot-like segregation and current's stirring action, the coaxial arrangement of ESR furnace will be the trend of ESR furnace design.

分析指出，为减少电抗造成的电能损失，消除散磁，降低电流的用，防止出现点状偏析，同轴设计电路（同轴导电立柱、同轴电缆）将会成为电渣炉今后的发展方向。
