Abstract
A continuous casting method and apparatus therefor wherein a reaction force/reduction controller selects a pivot reduction roll such that the thickness of the solidified shell of the cast slab having a liquid core is equal to the target thickness T.sub.ref, and calculates a difference between a thickness T.sub.in of the cast slab having a liquid core at the inlet of the reduction roll zone PRT and the target thickness T.sub.ref, i.e., .DELTA.T. The resulting value of .DELTA.T, i.e., a target reduction is provided to the reduction controllers 2 of the pivot reduction roll. The reaction force/reduction controller 1 assigns target reductions 1/3 .DELTA.T and 2/3 .DELTA.T to the two reduction rolls upstream of the pivot reduction roll. The reaction force/reduction controller 1 calculates a target pressure (P.sub.i +.alpha.) on the basis of the selected value for .alpha., and the resulting target pressure (P.sub.i +.alpha.) is provided to each of the reduction controllers 2 of the reduction rolls, downstream of the pivot reduction roll.
