(3) The method of hot rolling of the strip, which is conveyed into the final rolling strip of the predetermined thickness with the predetermined amount of stitches, and finally the strip is wound together with the production cost and the processing cost, together with the rolling mill (1) and the completion pressure. The heat loss of the rolled material 10 placed on the transfer path between the regiments 3 is reduced, so that the length of the intermediate-roller table 2, which is determined by the length L of the rough rolled strip 10, is reduced, At the time of the final rough rolling pass n-1 of the rough rolling strip 10, tandem rolling is performed on the finished rolling table 3 together with at least the rolling mill 1. The length of the mid-roller table 2 in the device constructed according to the above method corresponds to the length of the rough rolling strip 10 whose maximum is in front of the final rough rolling pass (n-x).
