Abstract

PURPOSE:To form an even alloy layer on slab surface layer with good volume productivity and workability by providing a partition wall which is partly dipped below molten steel level within a continuous casting mold and supplying a fixed amount of molten alloy between the partition wall and the inside wall of the mold by an electromagnetic pump thereby adding the same to the molten steel. CONSTITUTION:Molten steel is injected from a tundish 2 into a continuous casting mold through an immersion nozzle 3. The alloy 8 which has beforehand been melted in a melting furnace 7 is supplied at a fixed amount by an electromagnetic pump 9. While inert gas is being blown from an inert gas pipe 12 between a refractory-made partition wall 6 and the inside wall of the mold 1, the alloy is added to the molten steel 4 to make its diffusion easier while preventing its oxidation. When the molten alloy 8 is added, it forms the solute stagnating area of the alloy 8 under the level of the molten steel 4 and while this portion descends together with the molten steel 4 in the mold 1, it is cooled and solidified, whereby the alloy layer is formed on the slab surface part.
