Effects of the configuration of feed tip nozzle on flow field and temperature field in twin-rolling casting strip of magnesium alloy melt in cavity were described. Based on the SOLA-VOF finite differential method

the coupled model of flow field with temperature field in twin-rolling casting strip of magnesium alloy melt has been established to simulate the effects of different nozzle cavity structure on flow velocity of the magnesium melt and temperature distribution in magnesium melt under the same initial condition including the same height and temperature of the molten magnesium alloy in front box. The results reveal that decreasing the size and increasing numbers of the spacer are helpful to obtaining uniformly distributed flow field and temperature field in cavity of feed tip nozzle. The results are well in agreement with simulated ones

and the magnesium alloy strip with desirable quality can be produced based on simulated results modifying the structure of feed tip nozzle.
