Abstract
Ampere Scientific has previously developed and provided industrial validation of the VARmetricTM measurement system to measure the location of electric arcs during vacuum arc remeltingVacuum Arc Remelting (VAR) of high temperatureTemperature specialty alloys. With the advent of VARmetricTM, it is now possible to continuously monitor and control arc distributions in order to tailor the heat fluxFlux that drives solidificationSolidification during the VAR process. Laboratory experiments have applied transverse magnetic fields to generate specified Lorentz forces as a control mechanism across the arc gap in order to drive arc locations to predetermined distributions. This type of control makes it possible to react to undesirable arc conditions during VAR operations or to provide a continuous control to specify a thermal profile for heat input to the melt pool necessary for ensuring defect-free ingots.
