Numerical Modeling of Planar Flow Casting Process
This study sought to examine the effect of various process parameters on the thickness of the amorphous strip produced by Planar Flow Casting (PFC), which is used to solidify molten metals rapidly. The processes were simulated via fully coupled fluid flow, heat transfer, and solidification models. The temperature distribution and velocity profile of melt in the computational domain with given process parameters were investigated according to various melt inlet temperatures, size of gap between nozzle slots, rotating wheel, and ejection pressure. In general, stable shaping of ribbons was obtained given a heat transfer coefficient of 100 cal/cm2/sec/°C. Strip thickness was found to decrease with the pouring temperature of melt. The results evaluated based on the numerical model were verified based on experimentally measured data.
