Zusammenfassung:PROBLEM TO BE SOLVED: To improve joining strength between a preceding and succeeding bars without making large equipment investment to an existing hot strip mill. SOLUTION: In the method for completely continuous hot-rolling by which the tail end of the preceding bar and the tip of the succeeding bar which are materials in rolling between rough rolling and finish rolling are overlapped along the longitudinal direction and joined with a rolling mill, the length of the overlapped part in the longitudinal direction of both the bars is set to be
