Temperature Validation of 3D Model for the Reversing Hot Rolling in Connection with a Coil Model

The complex thermal modelling approach of the reversing hot strip rolling in connection with a coil model was developed. The coil model provides the modelling of the (un-) and coiling process. The modelling approach is based on object-orientated principals and implemented in MATLAB using library OOPDE and will be the base for the forecasting of the microstructure and the resulting material properties of strip during the reversing hot rolling. The model was validated using experimental data received after carrying out of the 2-pass reversing hot strip rolling of magnesium alloy AZ31. The results show a sufficient correspondence between experimental and calculated temperatures during the 1st and 2nd rolling pass.
