Abstract: PURPOSE: To improve the lubricity between a mold and a cast slab and to produce the cast slab having less surface defect, in a continuous casting method for molten metal such as steel. CONSTITUTION: Sets each of one or more high frequency coil 3 are separately arranged on a meniscus of molten steel on both short wall 11 sides of the mold, and even in the case of shifting the short walls 11 of the mold due to change of the width of the cast slab at the time of continuously casting steel, since the high frequency coils 3 are shifted while following the shifting of the short walls 11 of the mold, the casting is executed in the condition of always impressing the high frequency induction magnetic field to the short wall parts of the mold. Further, since the high frequency coils 3 are separately arranged above the meniscus on both short side meniscus from each other with an immersion nozzle 2 as a boundary, even when the change of the width is executed during casting, the immersion nozzle 2 and the high frequency coils 3 do not physically interfer with each other.  Therefore, the change of the width can freely be executed.
