Meeting Liquid Metal Processing & Casting Conference (LMPC 2022)
Symposium Liquid Metal Processing & Casting Conference (LMPC 2022)
Presentation Title Validation of Electro-slag Remelting (ESR) Process Simulations for HAYNES®282® Alloy Slab Ingots
Author(s) Ram Krishnamurthy, Michael Fahrmann
On-Site Speaker (Planned) Ram Krishnamurthy
Abstract Scope Results from a detailed validation study of the process simulation (using the commercial software MeltFlow-ESR®) of the ESR of a 282 alloy 10” thick slab ingot will be presented. As part of this study, Mo pellets were dropped into the crucible during the ESR of this slab at times chosen to reflect the initial transient, steady state and hot-topping stages of the process. The shape and temporal evolution of the solidification front as reconstructed from the locations of the Mo pellet markers compares favorably with predictions from the process simulation. Variations in ingot microstructure (primary / secondary dendrite arm spacings) with spatial extent across the ingot obtained by metallographic analysis are also compared with those predicted by the empirical dendritic kinetics prescriptions employed by MeltFlow-ESR®. Inferences drawn from these results relating to the effectiveness of the process simulations to faithfully capture experimentally observed characteristics will also be presented.
