Abstract：The bloom casting machine have three sections of electromagnetic stirring (M-EMS+S-EMS+F-EMS)， Masteel-Special Steel Company. In order to get the best parameter and improved internal quality. Shoot nail experiment near the S-EMS and F-EMS electromagnetic stirring zone. According to the test results of Shoot nail experiment， Simulation calculated the thickness of the shell on the electromagnetic stirring zone. According to the ideal target shell thickness， Simulation process parameters， Design the process optimization experimental program. The 380 mm round billet of medium carbon steel， optimum parameter can be attained and internal quality be improved， based on the contrast analysis about the macro-structure and composition segregation. to reduce the central segregation and shrinkage defects.
