PURPOSE:To cast continuously a deflectless billet free from foam and inclusions over the entire surface on the long and short side of a product, i.e., steel slab by conducting the swirling horizontal flow along the respective mold surfaces on the long and short sides in the molten steel surface part in a mold. CONSTITUTION:Continuous casting of a molten steel 4 cast into a mold for continuous casting of a steel slab is executed while the molten steel 4 in the mold 1 in contact with the mold surfaces on the long side is forced to flow horizontally by electromagnetic stirrers 2, 2 built respectively into both long side faces facing each other of the mold 1. Partition walls 9, 9 to bisect the spacing between both long side mold surfaces spaced from the respective short side mold surfaces of the mold 1 are immersed and installed into the molten steel 4 in the mold 1 to form the circumnutating flow passages of the horizontal flow. The swirling horizontal flow along the long and short side mold surfaces is thus induced in the molten steel 4 near the molten steel surface 5 in the mold 1. |
