Free metal surface resonance under alternating magnetic field low-frequency oscillations

Abstract

Abstract The article describes the definition of relationship between parameters of induction crucible furnace and meniscus shape using a mathematical model. The data obtained has been analyzed and the mathematical model qualitatively assessed using the open non-profit software Elmer and OpenFOAM. The models derived have been checked out to study the occurrence of free-surface oscillation resonance when subjected to pulsed action of an alternating electromagnetic field. Transients in an induction furnace crucible have been analyzed. A mathematical model with the electromagnetic field pulsed action has been created and free surface resonance occurrence and stability examined.
