ABSTRACT:
An electromagnetic horizontal casting process for continuously casting a flat ingot in a horizontal direction, including the steps of: transferring a mass of molten metal through a nozzle having an opening which has a rectangular cross sectional shape substantially corresponding to a rectangular transverse cross sectional shape of the flat to be formed, the cross sectional shape of the opening having long sides extending in the horizontal direction; causing the mass of molten metal to continuously emerge in the horizontal direction from an exit end of said nozzle; levitating the mass of molten metal which has emerged from the nozzle, in the horizontal direction with electromagnetic forces created by an upper and a lower electromagnetic coil which are disposed in a mutually vertically spaced-apart relation adjacent to the exit end of the nozzle; solidifying the levitated mass of molten metal into the flat ingot, by direct contact of the molten mass with a cooling fluid; and withdrawing the flat ingot continuouslly in the horizontal direction.
