Abstract：A series of measures were taken to solve the problem of central carbon segregation in billet in No.1 Steelmaking Plant of Rizhao Iron and Steel Co., Ltd., including reducing the liquid steel composition fluctuation, decreasing the superheat of hot metal in the tundish, developing an appropriate matching system of casting speed and temperature, keeping a constant casting speed, optimizing mould electromagnetic stirring parameters, controlling suitable secondary cooling strength, using the solidification end electromagnetic stirring and so on. The central segregation in high carbon steel billet was obviously improved. The pass rate of central carbon segregation (≤1.5 level) of high-carbon steel with≥0.60%carbon content is 100%.
