Abstract

PURPOSE:To minimize the upward flow owing to the collision of electromagnetic flow against the wall surfaces of the mold and stabilize the electromagnetic flow by approaching the positions of the linear motors which give electromagnetic flow to the freezing interface molten steel to the molten metal surface in the mold in order to form the sound frozen layer of a suitable thickness to the slab. CONSTITUTION:Linear motors 3 are provided along both long sides 2 in a slab mold 1 and their thrust is given in the mutually different directions 4, 4'. Electromagnetic flow 5 is thus given to the freezing interface molten steel up to the position where the frozen thickness corresponding to the scale thickness formed from at least during casting until the start of rolling. At this time, the installation positions of the linear motors 3 are approached as close to the molten metal surface 6 in the mold as possible within the range where the frozen layer of more than this scale thickness may be formed. As a result of this, the flow generated on the wall surface side of the long sides 2 of the mold collides against the wall surfaces of the adjacent short sides 9 and the upward flow out of the components going toward the long sides on the opposite side and those divided to the top and bottom may be suppressed. Hence, no large turbulence occurs in the molten metal surface powder 8.
