Numerical analysis of direct-chill casting of aluminum ingot
Direct chill (DC) semi-continuous casting is the most efficient way to produce large aluminum ingots. This process consists of three main stages; transient stage, steady-state stage, and post-drop stage. During transient stage, the ingot is subjected to rapid cooling rate and thus resulted in the …

Experimental observations and analysis of macrosegregation in rolling slab ingots
… This unprecedented demand drives aluminum casting methods towards increased productivity looking to, cast larger ingots faster. The unfortunate consequence of this approach is an enhanced variation of metallurgical properties over the cross section of slab ingots. Rolling slab ingots of …

An economic analysis of aluminum sheet production and prospects of aluminum for the automotive unibody
… was used to analyze the costs of traditional direct chill casting and subsequent rolling of aluminum alloy sheet and compared the technology to the alternative continuous casting fabrication method. A change to continuous casting displayed large potential cost savings and was believed to be …

Influence of ultrasonic cavitation treatment on fragmentation and de-agglomeration of primary intermetallics and oxides formed in Al alloys
… system by implementing UST in a conventional direct-chill casting setup. The casting trials demonstrated the positive impact of cavitation melt treatment on the grain refinement characteristics of end cast billet/ingots. The promising results from both fundamental and real-scale experiments …

Solidification behaviour of magnesium alloys
… particles, the role of solute, and the role of casting conditions. First of all, the study suggested that MgO particles can act as nuclei in magnesium alloys by measuring and analyzing the differences in cooling curves with various amount of endogenous MgO particles. The differences indicated …

Modeling transport phenomena and uncertainty quantification in solidification processes
<p>Direct chill (DC) casting is the primary processing route for wrought aluminum alloys. This semicontinuous process consists of primary cooling as the metal is pulled through a water cooled mold followed by secondary cooling with a water jet spray and free falling water. To gain insight into this …
