cerning dull work roll rolling 2 4 has however succeeded to explain quantitatively this peculiar elongation behavior with dull work roll skin pass rolling Furthermore in dull work roll rolling realization of prescribed surface roughness of rolled plates are also1/11/ 32 Moreover the larger diameter of real skin pass rolls increase the contact length between sheet and roll and therefore the sliding length per rotation Nevertheless the results of this investigation gives reason to expect an enhanced wear performance of laser implanted rolls in a skin pass or even tandem mill application
