The Vacuum Arc Remelting
(VAR) and Electroslag Remelting (ESR) processes are consumable electrode remelting processes used for producing ingots of higher quality than that of the original material by means of
controlled solidification and chemical refining. The VAR process
uses an inert atmosphere and is widely used for the producing Nickel-based superalloys and Titanium alloys for aerospace applications, and for producing high-performance structural steels. The
ESR process is used for producing non-reactive alloys such as Nickel-based superalloys and steels.
The performance of the
processes in eliminating of inclusions and achieving compositional uniformity is governed by complex interactions of electromagnetics, flow, heat transfer, and phase change phenomena.
Multiple remelting stages are typically used for producing the final ingot. A trial-and-error approach is ineffective for process optimization because of the complexity of the processes,
high operating costs, and measurement difficulties.
The computational models embedded in
COMPACT-VAR and COMPACT-ESR
consider all the underlying phenomena in a comprehensive and efficient manner for predicting the effects of process parameters on the quality of the ingots produced. Therefore, these software products offer a scientific and cost-effective approach for process design and optimization.
