Application research on 20 CrMnTiH(FQ) gear steel bloom by combined-EMS technology for homogeneity controlling was carried out on a 360 mm×450 mm continuous casting machine..The specific install position of EMS had been determined based on the result of numerical simulation calculate,and 10.0~11.0 m far away from mold liquid steel surface is the suitable position.The EMS process parameters have been researched and the effects of processes on homogeneous control have been compared.Process parameters that suitable for 20 CrMnTiH(FQ) gear steel bloom homogeneity control have been found out based on the actual magnetic intensity,that's M-EMS:(280±5)×10-4 T,F-EMS:(300±5)×10-4 T.Effective control for homogeneity of bloom have been realized,the average of standard mean square deviation for the degree of segregate is 0.052,and range is below 0.027.
