PURPOSE:To improve the surface characteristic and the quality, etc., for cast slab by arranging a short wall core block at back side of short wall side mold frame and also projecting the electromagnetic stirrer toward the short wall core block side by extending the end part of the stirrer. CONSTITUTION:The short wall core block 5 having the sufficient thickness is fixed at the back face of short wall side mold frame 2 and the end part of electromagnetic stirrer 4 is extended to the block 5 and the projecting part 4B is formed toward the block 5 at the extension part 4A. In this mechanism, the line of magnetic force from a coil of the electromagnetic stirrer 4 through the projecting part 4B forms the flux distribution moving molten steel at the short wall side and so the molten steel flow is developed at the short wall side. Therefore, deposit of the nonmetallic inclusion to the corner part is prevented and the surface characteristic and the inner quality of cast slab are improved. |
