Abstract
Mathematical models to estimate the rolling force P and the rolling torque G of hot roughing mill of aluminum were developed. These models consist of equations to calculate the rolling force function QP, the torque arm coefficient λ and the mean flow stress Kfm. The equation of QP and λ are derived empirically by analysing the rolling data. The equation of Kfm is based on the empirical expression of the experimental data by complastometer. Almost satisfactory accuracy is achieved in estimating P and G. The calculating method to obtain the pass schedule in the restrictions of rolling force, rolling torque, angle of biting etc. was developed. The total number of passes reduces and the productivity of roughing mill for aluminum alloys increases by using this new pass schedule.
