US 5,211,217 A · Vertical continuous casting method and casting apparatus

Abstract

Disclosed are a method and an apparatus for vertical continuous casting. The vertical continuous casting includes drawing a strand formed in a watercooled mold vertically downward therefrom, positioning light reduction pinch rollers just prior to the solidification completing point of the strand, and applying a light reduction force to the strand sufficient to compensate for contraction caused by solidification of the strand. By this procedure the formation of central cavities is prevented and central segregation is lessened. The light reduction pinch rollers are arranged to be adjustably positioned up and down along the strand, in order to compensate for fluctuations in the location of the solidification completing point of the strand.

Dependent claims

A continuous casting method comprising:

casting a molten strand of metal from a water-cooled mold,
drawing said strand vertically downward from said mold,
positioning a light reduction means about the strand,
determining a solidification completing point of the strand,
moving the light reduction means along an axis of the strand in a vertical direction to a point slightly above said solidification completing point, and
applying a light reduction force to said strand by said light reduction means sufficient to compensate for contraction caused by solidification of said strand.
