Resumo
The performance of hot strip mill work rolls usually is measured in tons per mm or wear kilometres per mm grind off. Main influences affecting performance are: roll related factors (wear resistance, operational safety including crack resistance, resistance against catastrophic failures like barrel breakage, spalling etc., and uniformity of shell microstructure and hardness); mill related factors (general working conditions including mill load, cooling, rolling program, roll shop practice – grinding and testing facilities and their proper use, etc.). From the roll manufacturer ́s side, only the roll related factors can be influenced, and this is why sometimes excellent rolls may show unexpectedly poor results. In this paper, strategies to improve wear resistance and operational safety of HSM work rolls will be described.
