Abstract
The temperature distribution of Mg–3Al–Zn plate along the thickness and its variation history during rolling was measured by thermocouples embedded in samples. A finite element model was proposed to predict this distribution and the agreement between experimental and computational results represented its validity. The temperature distribution was uneven due to the internal temperature rise effect and the surface chilling effect during rolling. The initial sudden temperature rise and the overall temperature rise through rolling both exhibited proportional relationships with thickness reduction, while inverse correlations with initial temperature. The temperature drop of surface layer first increased and then decreased as the amount of thickness reduction increased during rolling. However it gradually increased as initial temperature increased, reaching a maximum of 147°C. What's more, this surface chilling layer was only 1/6 of the total thickness and remained unchanged.
