Description
Summary:This work demonstrates and simulates the industry scale direct chill casting of magnesium alloy (AZ31) billets processed under various conditions. The solidification mechanisms involved the conventional and melt-conditioned direct chill casting processes are simulated using the computational fluid dynamics. The heat flow and the solid-liquid interface are clearly identified for various casting speeds, depth of the rotor-stator device and the device geometry. The results also indicate that the shape and depth of the solid-liquid interface sump is sensitive to the casting parameters.
