  • Reduction of off-centering at tail end caused by unstable

    Abstract In hot rolling the strip has been needed to be rolled harder and faster to obtain thinner and higher quality strip such as high strength steel. As the strip is rolled harder the strip steering tends to become unstable because of the unstable work roll position caused by the clearance between the work chocks and housing. Pinching might occur especially for tail end of rolled strip.
