Model and Simulation of Draught Pressure Distribution under the condition of High-speed Roll Casting

The static equilibrium differential equation in casting and rolling zones during high-speed roll casting process is deduced respectively using the slab method. The equation in the casting zone is numerically solved by Runge-Kutta method and that in the rolling zone is analytically solved according to the mixed frictional condition. Conventional roll casting of a roll caster is simulated based on these established models. The validity of these models is verified by the agreements of the calculating results with the experimental. Based on this fact, the virtual simulation of high-speed roll casting is carried out. Comparis on with the conventional roll casting of a roll caster shows that the designed parameters of mechanical properties of the roll caster under the condition of high-speed roll casting should be raised.
