Abstract

The present work is a contribution in improving the hydrodynamic method proposed by Li et al. (Steel Res Int 87(9999) 88:2053–2059, 2016; Int J Adv Manuf Technol. Springer-Verlag, London, 2016) used to predict the pressures and the rolling speeds during hot rolling of aluminum strips. The hydrodynamic model gives good prediction. However, it is based on empirical coefficients which must be identified for each rolling case. Therefore, a critical analysis of the Si Li’s method has been first made and then a methodology for improving it has been presented. The improvement consists in coming out of the empiric coefficients and considering the variation of viscosity as a function of pressures. Finite element simulations have been conducted to validate the improved method. Much reliable results have been obtained that are in good agreement with the experimental data. The proposed approach is rapid and much easier to use within the industrial application.
