THE WORK ROLL SURFACE DAMAGING STUDY: A KEY FACTOR IN USING HSS ALLOYS IN HOT ROLLING
2012
In many hot strip mills the front stands of finishing group are working with rolls made in High Speed Steels. The success in using these rolls is strictly in connection with the mill technology but also with redressing methods applied in the turning shop. The HSS rolls show an impalpable wear and then the evaluation of roll surface damaging assumes a strategic role to determine their performance. Furthermore the study of roll surface damaging becomes very important especially when assessing a roll steel grade within the same class of steel. The contents of this paper is focused on the analysis of redressing procedures and their use to optimize the performance of HSS rolls.
