Numerical modelling of high frequency inductive melting of ZrO2-SiO2 with a high processing temperature in an inductor-crucible furnace is considered. Features of melting of this two-component mixture in comparison with single oxides are discussed. Necessary initial heating of the load is performed either by inserting a metal ring or an additional gas burner at the top of the furnace. Special attention is paid to the formation of holes in the load due to sintering of the material. Basing on the numerical studies, the characteristic power requirements and main heat losses are estimated. Figs 8, Refs 7.
