Abstract：The thickness of solidified shell of strand in secondary cooling zone was first calculated with mathematics model and then confirmed with pinshooting in EAF Steelmaking Plant of Nanjing Iron and Steel Co., Ltd.. The position of crater end 35～55 mm in diameter was found by calculation with modified mathematical model and pinshooting for given casting speed and steel grades and after that the FEMS was fixed at 8 m from meniscus. The optimal parameters for electromagnetic stirring were determined by teslameter:550 A and 13 Hz.The chemical composition at crater and of billets cast with and without FEMS was analysed. The results showed that the carbon and center segregation coeffient of billet cast with FEMS was decreased from 1.09% to 1.01% and the peak sulphur content in center was reduced obviously. The electromagnetic stirring parameters are suitable.
