Abstract: Twin-roll continuous strip casting process has been simulated by using generalized fluid concept based on considerations of fluid fl ow, heat transfer and solidification. The simulation result shows that there is a relatively large range of circumfluent area in the pool, which acts as the mec hanical agitator. This conclusion provides a theoretical foundation for twin ro ll casting to produce high quality strip. The method proposed can be used in var ious fields where the conjugate of solidification heat transfer and fluid flowis dominant, such as metallurgy and petroleum engineering.
