| description | PROBLEM TO BE SOLVED: To provide a method for continuously casting steel by which the sticking of alumina etc., on the inner surface of an immersion nozzle is reliably prevented and a cast slab having good surface quality can be obtained. SOLUTION: In the method for continuously casting extra-low carbon steel, at least part of the inner surface of the immersion nozzle for supplying the molten steel from a tundish into a mold is constituted of a refractory containing alumina and graphite as the main components. While supplying the electric power from the immersion nozzle into the molten steel stream in the inner part, the continuous casting is performed. The potential difference between the immersion nozzle and the ground is made to be 0.5 to 5.0 V. COPYRIGHT: (C)2005,JPO&NCIPI |
