Resumo
High Speed Steel (HSS) work rolls are gradually replacing High Chrome rolls in hot rolling practice. Differences in rolling conditions made it necessary to develop various HSS grades to fulfill all mill requirements. The introduction of two different HSS materials, designed for the shell of work rolls used in front finishing stands of HSM is discussed. One type has been developed for harsh rolling conditions in order to guarantee maximum crack resistance. The other type has been designed for maximum tonnage performance and surface smoothness. The influence of the HSS microstructures on the characteristics of these work rolls and the resulting consequences on roll performance are shown.
