Group Mana­ger High Tem­pe­ra­tu­re Flows in Metall­ur­gi­cal Melts

Research

Phy­si­cal and nume­ri­cal flu­id flow simu­la­ti­ons of metall­ur­gi­cal melts and fur­nace atmo­sphe­res as well as phy­si­cal based pro­cess models of the­se reac­tors.

Fields of activity

• Remel­ting pro­ces­ses – Vacu­um Arc Remel­ting (VAR) and Elec­t­ro Slag Remel­ting (ESR)
• Refi­ne­ment of metall­ur­gi­cal melts by floa­ta­ti­on and buoyan­cy effects – SNIF box, tun­dish, ladle, …
• Water expe­ri­ments for phy­si­cal model­ling and vali­da­ti­on of nume­ri­cal simulations
• Case of dama­ge ana­ly­ses and refrac­to­ry optimization
• Pro­cess models of metall­ur­gi­cal reac­tors and furnaces
• Macro­sco­pic tex­tu­re examination

Projects
