4. Modeling – Simulation

4.1 State of the art

Like all metal and alloy production processes, VAR remelting has been the subject of a great deal of theoretical research, and still is in 2021. The mechanisms involved are complex and highly coupled. Mathematical modeling and numerical simulation have traditionally been used extensively by the R&D departments of the companies concerned to analyze and optimize the conduct of remelting operations. These tools enable better control of end-product quality, and provide essential support for the development of new products, reducing costs and development times. The development of mathematical models of reflow processes is almost systematically based on a partnership between process users, corporate R&D units and academic researchers. It's worth noting that VAR...
