Abstract
The distribution of temperature and flow fields in cast-rolling zone was obtained through the direct coupled solution of finite element method. Two vortexes appeared in the cast-rolling zone during twin-roll casting. The flow velocity along thickness of the magnesium alloy strip was heterogeneous, which resulted in the microstructure with the flow trace inclined to the cast-rolling direction. The temperature difference between the strip surface and at the center was about 150°C at the inlet and it declined to about 25°C at the exit. The increase of the casting temperature caused the raise of the strip temperature at the exit. The calculated temperature was consistent with the measured temperature.
