| Abstract: | This paper introduces the practice to solve the problem of centerline segregation of medium carbon steel slab produced by the straight curved continuous caster in a steelmaking plant.Thanks to the optimization of dynamic soft reduction parameters and the improvement of continuous casting process,the centerline segregation of the slab was decreased obviously,B grade centerline segregation ratio changed from 36.84 % to 15.91 %. |
