METHOD AND APPARATUS FOR CONTINUOUS CASTING

One or more streams of molten metal poured into a continuous casting mold (1) are acted on magnetically by static magnetic fields, covering substantially the entire width of the casting mold (1), thereby reducing the speed of the molten metal streams from the immersion nozzle (2), unifying the flow...

More Information
Summary:One or more streams of molten metal poured into a continuous casting mold (1) are acted on magnetically by static magnetic fields, covering substantially the entire width of the casting mold (1), thereby reducing the speed of the molten metal streams from the immersion nozzle (2), unifying the flow profile of the molten metal in the mold (1), preventing trapping and accumulating of mold powders and inclusions into the cast products. Magnetic poles (3) are provided which are at least as wide as or wider than the minimum width of the cast products and the iron core (F) is arranged on the same face of the casting mold (1) with mutually opposite polarities in the drawing direction. Even if casting conditions change from time to time, defects in final products made of the cast metal are substantially reduced.
