Abstract
Roll grade evolution in plate mill applications is traditionally following the development in hot strip mills. New grades normally find their way into service only after being successfully implemented in hot strip production. The majority of the plate mills worldwide are using work roll grades that have been invented before the 1980’s. But today the demands in the mills are pushed by sophisticated product mixes and longer rolling campaigns. The result of this development is a higher wear rate on the work rolls and as a consequence roll hardness is increased and advanced roll materials are used. The backup rolls are also affected by this. The wear rate is higher and the mechanical impact in terms of contact pressure and work hardening is increasing. This paper outlines the results of the roll grade development at Gontermann-Peipers and introduces new materials for work and backup rolls for plate mills.
