摘要：

The effect of complex electromagnetic stirring combined M-EMS with F-EMS on solidification structure and segregation in high strength 60Si2CrVAT spring steel bloom has been studied. It is found that the extent of the equiaxed structure is considerably increased and solidification structure is modified by the complex electromagnetic stirring. Moreover, the ratio of central carbon segregation remarkably reduced. Therefore, the problem of inner porosity and composition segregation can be solved with the process in spring steel 60Si2CrVAT bloom.
