Calculation of the Melt Surface Shape in Different Induction Crucible Furnaces

Abstract:

The calculation algorithm of the melt surface shape of the induction crucible furnaces (ICF) taking into account the variable melt level in crucible is developed. The special-purpose software package for calculation of the height and melt surface shape in ICF is developed. The investigation results of the melt surface shape and its influence upon energy and electric characteristics of the ICF are presented.
