The positive segregation in the upper center and the negative segregation in the exterior region of the ingot are found at the same time.
还发现，在铸锭的中心靠上的区域形成正偏析，在铸锭的外部区域形成负偏析。

On the contrary, the surface imperfections, such as oscillation and subsurface segregation etc, found in DCC ingot, cause the mechanical properties drop largely.
相反，普通连续铸造锭表面因存在振动痕和亚表面偏析等铸造缺陷，力学性能大大降低。

The results show that suspension casting can make the temperature field uniform, eliminate macro segregation of c, s and p, and improve the quality of bearing steel ingot.
