Method of and rolling mill train for producing bar-shaped rolled products

A rolling mill train for rolling a bar-shaped stock to a predetermined end height and end width measured transverse to the end height, the rolling mill train comprising a plurality of arranged one after another, active rolling mill stands having adjustable roll nips and forming rolling mill stand pairs;

• a respective plurality of hydraulic cylinder units for adjusting the roll nips of respective rolling mill stands;
• a respective plurality of roll nip control units for controlling the respective hydraulic cylinder units so that at least a fraction, individual for each of the rolling mill stands, of rolling force-caused spring-offs of the respective rolling mill stands is compensated;
• memory means for storing material characteristics, end heights and end width of already rolled stocks, and for storing constant and set-up parameters of the rolling mill stands;
• input means for inputting material characteristics, end height and end width of a new to-be-rolled stock, and comparison means for comparing the material characteristics, the height and the width for the new to-be-rolled stock with the stored material characteristics, the end heights and the end width for the already rolled stocks, and for comparing instantaneous parameters of the rolling mill stands during rolling of the new rolled stock with the stored parameters of the rolling mill stands, whereby upon coincidence of the parameters for the new stock with the stored parameters for an already rolled stock, the rolling mill stands are pre-adjusted to set-up parameters for the already rolled stock with the material characteristics, end height and width corresponding to the new stock.
