A Versatile Thermal-Mechanical Model for Twin-Roll Casting
Abstract Twin-roll casting has been widely used for producing thin strips and sheets. In twin-roll casting, molten metal is fed into the gap of a pair of counter-rotating, water-cooled rolls. In this paper, the development of a semi-analytical model of the thermal-mechanical behavior is presented. A mechanical model is coupled with thermal models to predict roll pressure distribution and roll separating force. To demonstrate its versatility and reliability, the results predicted by this model are compared with experimental data available in the literature and good agreements have been found between this modeling results and experimental observation. Also, for given operating conditions and material properties, the closed-form relationship between productivity and strip thickness has been established.
