Resumo

Use of forged HSS work roll is more and more widespread in cold rolling mills for various configurations as reversing or tandem mill with 4Hi or 6Hi stands and various rolled steel products as tin plate, silicon sheet or automotive sheet. The trend to roll high strength steels as AHSS grades or GO silicon steels requires higher rolling load and leads to replace standard forged (3% to 5%Cr) work rolls by forged HSS rolls: the forged HSS rolls present enhanced roughness retention, strengthened resistance to thermal and mechanical stresses, enable extended rolling runs while decreasing stock removal. Moreover the chrome plating practice can be suppressed when used in cold rolling process. The present paper aims to sum up the different applications and associated performances achieved with the forged HSS rolls.
