Abstract:

The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, which is part of a project to predict the work roll initial crown in order to obtain desired strip profile in hot rolling, the effect of work roll wearing crown is taken into consideration. A linear regression model is proposed to predict the work roll wearing crown using experimental data provided by Mobarake Steel Complex (MSC). The results of this model are compared to Oike wearing model. It shows that the empirical model predict the wearing crown more precisely than Oike’s model in the mentioned mill.
