Horizontal continuous casting method

摘要

A horizontal continuous casting method for continuously feeding a molten metal stored in a tundish through a tundish nozzle located in the vicinity of the tundish at its bottom to a mold horizontally connected to the tundish nozzle to produce a strand, wherein an electromagnetic field generating device is arranged in the vicinity of the boundary between the tundish nozzle and the mold for exerting an electromagnetic force directed toward a center of the molten metal flowing through the vicinity of the boundary or in a strand withdrawing direction, to separate the molten metal from the inner surface of the tundish mozzle anterior to the boundary with respect to the strand withdrawing direction, to allow the molten metal to come into contact with the inner surface of the mold posterior to the boundary with respect to the strand withdrawing direction. Control of the electromagnetic force exerted on the molten metal is effected by the electromagnetic field generating device arranged in the vicinity of the boundary in such a manner that a point at which the molten metal begins to come into contact with the inner surface of the mold coincides with a predetermined point. The electromagnetic force may also be controlled in such a manner that the points at which the molten metal begins to come into contact with the inner surface of the mold are brought to the same position peripherally of the molten metal with respect to the axis thereof.
