Abstract
The present invention relates to a method of controlling the productivity of a rolling plant having at least first and second rolling stands by processing a single slab of metal having a thickness, into metal strips having different thicknesses less than the thickness of the slab in accordance with strip output requirements of the rolling plant. The output requirements for strips having at least first and second different thicknesses to be produced by the rolling plant is determined. The slab is then rolled in a first rolling stand to reduce the slab thickness to produce a transfer bar. The transfer bar is sheared into first and second transfer bar portions such that the first and second transfer bar portions are sized to correspond to the output requirements for the first and second strips, respectively. The first transfer bar portion is then rolled in one of the first and second rolling stands to reduce the first transfer bar portion to produce a first strip having a first thickness.
