Status and Development of Improving Macro-segregation of Casting Billet by Electro-magnetic Stirring
Macro-segregation is a common defect that occurs during the solidification of continuous cast steel.Severe macro-segregation has great influence on mechanical properties and service life of steel.Significant progress has been reviewed in controlling billet macro-segregation,and many techniques have been successfully implemented in the pro-duction process.The status of adopting electromagnetic stirring technology to solve billet macro-segregation at home and abroad was described from aspects of experimental research and numerical simulation,and the characteristics were compared.Furthermore,factors of electromagnetic stirring affecting billet macro-segregation was summarized,provid-ing guidance for future applications of electromagnetic stirring to solve billet macro-segregation.
