Abstract

Abstract

In order to optimize the homogeneity and compactness of rail steel, the effects of continuous casting electromagnetic stirring on the dendritic structure and homogeneity of rail steel was analyzed by industrial experiments. The results show that blooms produced without electromagnetic stirring have no obvious dendritic structure partition, the dendritic structure tends to be more compact and the homogeneity is better for the area in which from narrow surface to 80 mm below, while central segregation tends to be worse. The F-EMS is more suitable both for optimizing homogeneity and compactness than M-EMS. Central segregation control of experiment blooms could be make up, Central segregation of rails rolled from the experiment blooms is well, and the same as rail head, range value of segregation degree for Mn is 0.098, value of compactness degree is 0.9764.
