Abstract

PURPOSE:To improve the efficiency of the rolling work, by arranging the work rolls of higher circumferential speed so as to make their positions against the material to be rolled alternately different, and by arranging them so as to make at least two passes come to the same side, in a rolling line wherein plural differential-speed rolling passes are to be carried out. CONSTITUTION:The differential-speed rolling mill 1 wherein the work roll 3 of higher circumferential speed is located on the upper side and the work roll 4 of lower circumferential speed is located on the lower side, and the differential-speed rolling mill 1' wherein the higher speed work roll 3 is located on the lower side and the lower speed work roll 4 is located on the upper side, are combined for rolling a material 2 to be rolled; hereupon, the differential-speed rolling mill 1, for example, is arranged so as to form two or more passes continuously. Hereby, the working ratio of the material 2 to be rolled becomes large without increasing the draft percentage, and the efficiency of the rolling work is improved, as compared with the equal-speed rolling mills' performance.
