The speed of the individual rolls in multiple roll bridle systems is made adjustable and independent of roll diameter for maximum alteration of strip passing over the rolls, by providing first, plural, independent drive means for a plurality of corresponding rolls in each of a set of entry rolls and a set of exit rolls, and second drive means providing common power input to a plurality of ...


Appropriate work roll shifting strategy in the finishing hot strip mill can make roll wear uniform and contour smooth. To eliminate the problem of roll shifting position duplication due to available roll shifting strategy, the optimized work roll shifting strategy is proposed in the hot strip rolling mill with continuous variable crown work rolls, using the k-nearest neighbors algorithm.

Rolling Mills Rolls. Rolling had assumed importance in the industrialized world during the nineteenth century. Profiles and flats are hot rolled while some flat products are also cold rolled. Rolls are tools in the rolling mill. The weight of the rolls can vary from a few kilograms to as high as 250 tons.
