Abstract
A bloom is heated and rolled by the flying shear system so as to produce a semi-finish rolled billet having a reduced cross section. A CLSI value, which is indicative of the uniform length of each of a number of product billets that can be cut from the length of the semi-finish rolled billet while maintaining predetermined optimum head and tail scrap lengths, is then calculated by the flying shear system. The cross section of the semi-finish rolled billet is corrected, so as to produce a finish rolled billet having an adjusted length, when the CLSI value is not within a safety billet length range, to thereby obtain a new CLSI value that falls within the safety billet length range. A flying shear cuts the semi-finish rolled billet or the finish rolled billet into the number of product billets when the CLSI value is within the safety billet length range.
