PROCESS OF CONTINUOUSLY CASTING STEEL SLAB USING ELECTROMAGNETIC FIELD

A process for continuously casting steel slabs employing a molten steel containing an oxygen concentration of 30ppm or less, preferably, 20ppm or less, using a straight immersion nozzle to which an inert gas is not injected, and disposing a static magnetic field generator on the back surface of the...

Summary:A process for continuously casting steel slabs employing a molten steel containing an oxygen concentration of 30ppm or less, preferably, 20ppm or less, using a straight immersion nozzle to which an inert gas is not injected, and disposing a static magnetic field generator on the back surface of the mold for applying the strong static magnetic field to the molten steel within the mold, thereby restricting the flow of the molten steel. With this process, it is possible to prevent the nozzle blocking, and hence to obtain the steel slabs excellent in the internal and surface qualities.
