Abstract
A continuous casting method in which a molten metal obtained by melting titanium or a titanium alloy is injected into a bottomless mold having a rectangular cross-section and withdrawn downward while being caused to solidify, wherein a plasma torch (7) is caused to rotate in the horizontal direction above the surface of the molten metal (12) in the mold (2), and a horizontally rotating flow is generated by electromagnetic stirring on at least the surface of the molten metal (12) in the mold (2). It is thereby possible to cast a slab in which the casting surface condition is excellent.
