| Abstract Scope |
An innovative method of modelling vacuum induction melting (VIM) is developed for industrial casting software, with applications in the investment casting industry. An induction coil is used to melt a nickel-based superalloy in a ceramic crucible. Once fully molten, the alloy pours into an investment casting mould which is attached underneath the crucible. The approach involves performing induction heating simulations to determine the temperature profile of the billet, at the point which it becomes fully molten. This is then applied as the initial condition for a mould filling and solidification simulation. Temperature data for the alloy is compared to experimental results obtained from in-situ industrial experiments using a bespoke VIM chamber with additional viewing ports. The benefits of applying this methodology for simulation modelling are explored. This includes improved defect occurrence prediction for finished castings, by capturing defects which were not predicted by a standard modelling process. |
