Crack Formation in Chill Block Melt Spinning Solidification Process: A Comparative Analysis Using OpenFOAM®

The application of FeSiB family magnetic materials in the electrical or electronic industry has significantly increased owing to development amorphous and nanocrystalline metallic glasses using melt spinning chill block technology, which involves a rotating metal wheel with high rotation speed. With this technique, thin ribbon is obtained jet liquid expelled from casting nozzle at pressure temperature over outer surface wheel. cooling rates that can be achieved lead disorder crystalline lattice metal, dependent on chemical composition. As soon as material by nozzle, turbulence occur solidification puddles. This generates defects cracks profile. In study, numerically simulated ad hoc events OPENFOAM® are comparatively examined real process.
