PROBLEM TO BE SOLVED: To provide a continuous casting facility capable of preventing capture to a coagulation shell of an acid-removed product, an Ar gas bubble and mold powder, when continuously casting by impressing a DC magnetostatic field over the whole width direction of a slab casting piece.SOLUTION: A continuous casting facility according to the present invention is a continuous casting facility having an upper magnetic pole 6 having the center positioned on an upper side than a discharge hole 5 of an immersion nozzle 4 and opposed by sandwiching a casting mold long side 2 and a lower magnetic pole 9 having the center positioned on a lower side than the discharge hole of the immersion nozzle and opposed by sandwiching the casting mold long side, on a back face of the casting mold long side, and impressing a DC magnetostatic field over the slab casting piece whole width from the lower magnetic pole, and superimposably impressing the DC magnetostatic field over the slab casting piece whole width from the upper magnetic pole and an AC movement magnetic field over the slab casting piece whole width, and a DC electromagnet for impressing the DC magnetostatic field of the upper magnetic pole, is divided into four parts in a width direction of a casting mold, and is constituted so that magnetic flux density impressed from the DC electromagnet can be independently changed by the divided respective DC electromagnets. |
