Abstract
An apparatus for continuous casting of molten steel comprises a continuous casting mold; an electromagnetic stirring coil, which rotates and fluidizes molten steel inside the mold and which is installed outside the mold; and a screen of ferromagnetic substance positioned between the mold and the electromagnetic stirring coil at a height including a level of meniscus. A method for continuous casting of molten steel comprises the steps of pouring molten steel into a continuous casting mold; applying an electromagnetic force to the molten steel in the mold by means of an electromagnetic coil installed outside the continuous casting mold; and shielding said electromagnetic force by means of a screen of ferromagnetic substance installed between the mold and electromagnetic coil at a height including a level of meniscus.
