<P>PROBLEM TO BE SOLVED: To provide a method of commercializing passing residual materials on a hot-rolling line, by which even when trouble occurs during the finish rolling of a preceding material on the hot-rolling line, the succeeding material is commercialized without making it the passing residual material, and remarkable drop of yield and downtime are prevented. Ž<P>SOLUTION: In this method of commercializing the passing residual material on the hot-rolling line, when the trouble occurs on a part of finish rolling stands during the preceding material is rolled in the finish rolling on the hot rolling line, the reduction is released after the rolling of the preceding material in the finish rolling stand where the trouble occurs and also the succeeding material to be the passing residual material is rolled with usable finish rolling stands in which the trouble does not occur and, by changing the cooling pattern, the passing residual material is made into a new product which has thickness different from that of the original target sheet.
