Abstract

The temperature field in cast-rolling area of the AZ31 magnesium alloy was simulated using the computer fluid software ANSYS Fluent

which is based on the conditions that the molten alloy of castrolling area is the same continuum

roll casting process is steady and the melt is incompressible.The three dimensional temperature field distribution of cast-rolling area of the AZ31 magnesium alloy strip cast-rolling

were investigated

with different process parameters

such as pouring temperature

roll casting speed and cooling water flow rate and effects of the temperature field distribution on the stability of strip cast-rolling process were presented.By comparing and analyzing simulation results

the optimum process in the selection range can be presented as follows:pouring temperature of 853 K

rolling casting speed of 9m/min

cooling water flow rate of 3m/s.
