Temperature distribution along the width and the thickness directions under different conditions was evaluated. Emissivity of AZ31B plate as an important heat transfer parameter in the air-cooling process was modeled accurately. Empirical Stefan-Boltzmann equation was modified and optimized to be the temperature control model of the process. Heat transfer coefficient between the plate and the environment was accurately defined and further fitted.
