The gap crown between two work rolls of plate mills and the strip shape can be adjusted by axial shifting of the work rolls, both of them have a special contour.

Application of FEM to plate hot rolling;

Heat treatment of Mg-Zn-Y-Zr alloy rolling sheet

The results show that the grains in the single direction rolling sheet is changed from strip to equal axis shape because of the recrystallization and twin crystals disappearance during annealing heat treatment,and there are some fine grains although part grains are grown.
