Numerical Simulation of Solidification Processes of Copper Alloys by Vacuum Continuous Casting

Abstract:

Article Preview

A numerical simulation method is used to analyse the microstructure evolution of 8-mm-diameter brass (70wt%Cu30wt%Zn) rods during the vacuum continuous casting (VCC) process. The macro-and micro-scale coupling method is adopted to develop a temperature field model and a microstructure prediction model. The effects of casting parameters, including casting speed and pouring temperature, on the shape of the solid-liquid (S/L) interface and solidified microstructure are considered. Simulation results show that the casting speed has a large effect on the shape of the S/L interface and grain morphology.
