Rolling of AZ31 Magnesium Alloy Strip Using Induction Heating Rolls

Magnesium alloy strips are difficult to produce through cold forming process due to their poor deformation ability. In this article, fabrication of AZ31 alloy strip by Hot-roller warm rolling process was studied. Experiment using induction heating rolls was carried out, its results confirmed that this technique can improve plasticity of AZ31, and reduce its processing difficulty. The temperature change in deformation zone during Hot-roller warm rolling with a roll temperature of 150∼350 °C was analyzed by numerical simulation. Finally, a prediction equation of deformation temperature in strips during Hot-roller warm rolling process was established.
