Abstract

In twin-roll thin strip casting, the temperature of a casting roll affects the roll, thermal stress, and influences the thermal deformation, the generation of roll surface cracks, the strip shape and the service life of the casting roll. In this paper, the features of the clad materials of the casting roll have been analysed, the effect of the clad thickness on the temperature field and thermal stress of casting roll has been simulated and discussed. The results show that the thick clad results in the increase of thermal resistance and then causes higher surface temperature of the clad layer, but lower temperature of copper roll sleeve. The heat expansion of the clad layer increases when the clad thickness decreases. The developed temperature model of the casting roll is helpful in optimising the design of the casting roll twin-roll strip casting.
