Theoretical analysis and experiment research of electromagnetic casting of steel by electromagnetic dimensionless number

Electromagnetic processing of materials is greatly highlighted due to its outstanding performance to enable the product quality and the productivity to be enhanced. As one of such technologies, the electromagnetic casting technology is considered as a potential process to drastically improve the surface quality of its products and to eventually increase the productivity of the continuous casting process. Attainment of the electromagnetic casting technology has been mainly dependent upon the role of magnetic force/pressure of the electromagnetic field. The important technique occurring in the electromagnetic casting is the support of the molten metal by electromagnetic force. The equilibrium between electromagnetic force and the static pressure of molten metal is the key to attain electromagnetic casting.
