摘要：A method and an apparatus are provided for electromagnetic stirring during a
continuous casting process, especially for casting a billet and bloom of medium and highcarbon steels. The method and apparatus provide a higher surface quality of the ingot,reduce the entrapping of nonmetallic inclusions into the ingot, and suppress issuesregarding central segregation and central porosity. The method provides an
improvement in the stirring process from the meniscus to the crater end—and relates toin-mold stirring and stirring in a zone of secondary cooling and up to the crater end. Thein-mold stirring is geared towards the suppression of meniscus disturbance, for
submerged casting, in particular, the reducing of helical and axial velocity components ofthe molten steel, the lowering of the initial solidification point to avoid the touching of ashell edge with the slag ring, and a decrease of oscillation marks.
