  • Patent number: 4519439
    Abstract: A method for preventing segregations in continuous casting by deforming the continuous strand plactically during the solidification in such a way that the cross-sectional area of the strand is physically reduced on a mount corresponding substantially to the solidification and cooling shrinkage of the material along the solidifying strand length. The method avoids upward or downward transport of melt in the solidifying strand. The reduction in most cases will be 2-6% and can be accomplished with apparatus having a number of pairs of strand reducing rolls or jets along the strand, to reduce it a number of times, each time less than the total desired reduction. The degree of reduction of the strand from casting to the final strand corresponds to the solidification and cooling shrinkage.

The reduction of the strand from casting to the final strand follows the solidification shrinkage.
