21, 39, 40]. In Steckel mill lines, during the hot rolling process, the strips are driven by the roller table in the rolling direction. However, the rolling procedure is susceptible to impel the strips perpendicularly to this direction, which could induce misalignment. For instance, the unaligned strips are prone to collide Aline de Faria Lemos

Steel mills ' primary feature is rolling steel, a procedure that reduces the cross section of the metal while increasing its length proportionately. Generally, rolling mills are graded according to the content they produce. Direct drive is chosen if the mill's speed allows. In general, direct drive (directconnected motor) is not desirable for speeds less than 150 rpm and outputs less than 750 kW.
