In the withdrawing stage following the secondary cooling zone, each pair of rolls of a plurality of pairs of rolls reduces the cross section less than 1.5 percent at the portion between the liquidus line and solidus one in unsolidified phase, thereby to produce a sound cast piece without producing the known center segregation and the known center porosity.

Continuous casting process

A method of shape control for a tandem mill for rolling strip, wherein the shape of the rolled strip at the delivery side of the final stand is detected to provide a signal corresponding to the long-edge shape, whereby the pattern of roll bending force for two or more latter stands are adjusted according to the signal or signals obtained in order to effect desired shape control without causing variations in the thickness of the strip at the delivery side of the last stand.
