Based on CLYNE-Kurz model,segregation model of grain-oriented silicon steel during solidification of continuous casting was established,segregation of Mn and S elements in liquid phase during solidification of continuous casting was calculated,and the relationship between actual concentration product and equilibrium concentration product of Mn and S during solidification of continuous casting was compared.The results show that the secondary dendrite spacing decreases with the increase of cooling rate.The secondary dendrite spacing in columnar region is 191.3 μm.The degree of segregation increases with the decrease of the distribution coefficient of elements.The degree of solute segregation increases with the increase of solid fraction.When the solidification fraction reaches 0.997,MnS begins to precipitate.
