Description
Summary:In this paper,the best final EMS frequency for bloom continuous casting is proposed.For 280×380 bloom,the best frequency is in the range of 4~7 Hz.Simulation results also show that,with this frequency,the electromagnetic force in the molten steel in the bloom reaches stronger and the electromechanical transformation rate of the stirring equipment is higher.The flow fields in the bloom with the various stirring parameters are simulated also.The final EMS parameters for bloom are optimized base on the simulation results.The experimental results show that,for high carbon steel,the best stirring frequency is 7 Hz and the current is 500A.In order to alleviate negative segregation of the low and medium carbon steel,the stirring frequency and the current should be 4Hz and 430A,respectively.
