The process of vertical twin-roll casting including pouring, solidifying, rolling and cooling can be accomplished
in a very short time. Some important process parameters in roll casting that are not difficult to be obtained in
experiment may be acquired using numerical simulation. In this paper, a numerical simulation based on a 20
finite element model of vertical twin-roll strip casting coupling temperature, flow and thermal stress has been
conducted. The influences of key process parameters including pouring temperature and casting speed have
been studied. The distribution of thermal stress was obtained, and its effect on cracks on the surface of the strip
was discussed.
