Abstract

Abstract

The morphology, distribution and relationship between the original bulk carbides and carbon segregation index of GCr15 bearing steel continuous casting billets under different continuous casting factors (superheat, drawing speed, secondary cooling strength, electromagnetic stirring conditions) were investigated by Image-Pro Plus software and metallographic method. The results show that the heritability of the original bulk carbide of different types of billets, intermittently distributed or individually distributed billet bulk carbide after the existing rolling heating process, the liquid precipitation carbide level is 0-0.5, which guides the best matching process parameters for continuous casting is the drawing speed 0.95 m/min, superheating degree 20-25 ℃, cooling intensity 0.35 L/kg, end electromagnetic stirring 350 A/7 Hz.
