Vertical direct chill casting is a conventional method for producing wrought aluminum alloy billets. The homogenization process must be carried out in cast billets because of β-AlFeSi intermetallic particles, often held responsible for surface defects and poor extrudability, are replaced by the more spherical discrete α AlFeSi particles during soaking. Homogenization is a three-step heat treatment that occurs after casting: heat-up, soak, and cooldown. In comparison to batch type furnaces, continuous homogenization can provide homogenization temperature uniformity, reduce soak time, and increase cooling rate. The cooling rate has a significant impact on the size of Mg2Si particles precipitated in aluminum billets. In this case, Mg2Si particle size of a continuous homogenization furnace is finer than batch type. In this study, the CFD analysis was conducted for different homogenizing furnace. However, microstructures analysis for each furnace’s products were investigated optical microscopy and SEM for understanding β→α transition and Mg2Si particles size.
