rolling kinematics, the outer rings of the double row tapered roller bearings and the housing washers of the axial spherical roller bearings are preloaded on both sides to a minimum load by means of springs (Figures 7 and 8). In strip mills, in fine-section and wire mills, the rolling speeds are so high in many cases that it is

In the manufacturing process of hot strip continuous rolling, it is one of key factors to ensure stability rolling and better quality of strip, to keep the relatively invariable strip tension between two stands. Draft compensation was adopted, which takes the initiative to compensate roller speed, in order to decrease the coupling effect of automatic gauge control subsystem, …
