Abstract
Abstract Temperature detection and tracking of AZ31B magnesium alloy plate during the air-cooling transport process were investigated and carried out under different thicknesses and initial temperatures. Experimental results show that there exists a sudden temperature drop in the range of 1/4 of width distanced from the edge. When the plate is cooled by 25–56 °C, the maximum inhomogeneous temperature distribution under all process conditions will appear in width direction. For the air-cooling transport process, the temperature control model for predicting the average temperature of the Mg plate after a predetermined time period can be established by modifying the Stefan-Boltzmann empirical equation. The model mainly depends on the plate specifications and air-cooling time.
