Research Progress in Central Segregation Control in Continuous Casting
Central segregation worsens the quality of slabs or billets of continuous casting and their subsequent rolling process.On the basis of elaborating the reasons for the central segregation formation,technologies in controlling the central segregation,such as low superheat casting,secondary intense cooling,electromagnetic stirring,soft reduction,stripe-feeding in mould,as well as the related processing mechanisms were introduced.Specially,the application of the stripe-feeding technology in continuous casting was remarked.
