Abstract

PURPOSE:To reduce the number of mills included in a rough rolling mill group in order to shorten the length of a rolling line, by carrying out a tandem rolling pass with whole rolling stands after carrying out a reverse rolling pass with rolling stands on the upstream side of a tandem arranged mill group. CONSTITUTION:A reverse rolling pass (roughing pass), comprising a single pass in the normal direction and a single pass in the reverse direction, is carried out with whole or a part of plural rolling stand group, F1-F4 for example. Then, a single finishing pass in the normal direction is carried out by whole stands F1-F6. By the present method, the length of the line is shortened. Besides, since a small temperature drop is caused during the rolling process, the discharging temperature of a heating furnace can be set low, so that such a loss as the scale loss, is reduced and the yield is improved.
