Effect of Contact Heat Transfer on Hot Rolling of Aluminum Alloy

Abstract The finite element simulation of the hot rolling process for 7075 aluminum alloy was carried out by using DEFORM-3D software. The heat transfer phenomenon in the hot rolling process was analyzed based on assumed boundary conditions; the effects of heat transfer on the plate temperature distribution, plate stress and strain distribution in the hot rolling processwere studied, respectively. The results indicated that heat transfer between rolling plate and roller in the hot rolling process is an important factor that affecting the rolling plate temperature distribution; lower heat transfer coefficient helps to reduce the heat loss, decrease the rolling stress and improve the rolling deformation.
