Abstract：Two kinds of continuous casting billet produced by the 50 t EAF and converter steelmaking production lines in new two area had been researched and the reasons and types for the formation of internal cracks had been studied by SEM and EDAX. The quality of casting billet improved, macrostructure and hot upsetting percent of pass enhanced significantly through implementation of these measurements such as casting with stable casted velocity, reasonable matching between casting speed and water quantity, controlling with narrow temperature wave of molten steel in ladle and heightened the purity of molten steel.
