Roll wear is a complex process where mechanical and thermal fatigue combines with impact, abrasion, adhesion and corrosion, which all depend on rolling system interactions rather than material characteristics only. The principal aim of this study is focused to the relationship between the rolling campaign, the pass schedule and work roll stress amplification by wear model and work roll fatigue damage. The roll wear and stress amplication prediction model are developed on real process working condition in computer. Wear pattern is calculated with various hot rolling pass schedule. The stress amplification effect in worn roll is proved through FEA by using ANSYS Workbenchⓡ. The stress amplification factor is calculated by comparision normal contact in dressing roll with abnormal contact at worn roll edge.
