| Abstract: | The effect of electromagnetic stirring current and frequency parameter at secondary cooling area on the central segregation and equiaxed crystal ratio of XG800WR non - oriented electrical steels slab was investigated through the methods of chemical and macrostructure analysis.The results shows that the rate of equiaxed crystal zone is going up with increasing of current intensity and current frequency.Electromagnetic stirring in the secondary cooling area can be easily reduced segregation caused by Sulphur.Experiment shows the best parameters of electromagnetic stirring to reduce segregation of Sulphur are 380～400A current and 6Hz frequency. |
