The key technologies, such as M-EMS, secondary cooling scheme, dynamic soft reduction, and its application to bloom continuous casting for heavy rail steel were presented. The operation shows that the defect-free blooms achieve 100% of total blooms produced from CC, center looseness and central segregation are ≤1.0, while, central shrinkage cavity is ≤0.5, central segregation index of carbon is ≤1.05, and the ratio of equiaxed zone is ≥38%. The qualified blooms are delivered to produce rail for high-speed tracks.
