Abstract

Abstract

The behavior of carbon and sulfur segregations of 82B hard wire steel produced under different continuous casting conditions has been systematically analyzed based on field tests and laboratory analysis.The results show three factors including superheat,casting speed and F-EMS which influence segregation of billets work differently with the variations of inner parts and segregation elements.For the central segregations of carbon and sulfur,the effect of casting speed dominates over the other factors.Under high casting speed,proper increase of secondary cooling intensity could effectively decrease carbon and sulfur segregations of billet,especially for the central part of the billet.The hydraulic simulation of tundish shows the optimal casting speed should be 1.8 m/min.
