Investigation of the skull melting method for the generation of particulate material of inorganic compounds

Abstract

This paper describes the application of the skull melting method for an artificial generation of particulate material of inorganic compounds like CsOH, NaOH, SnO 2 and UO 2 . The skull melting process is analyzed analytically. Thereby the electromagnetic field is calculated by a one dimensional time harmonic model. Thermal losses are estimated by simple analytical formulas. Finally an electromagnetic thermal field coupling is performed to calculate the temperature distribution inside the crucible, considering transient thermal effects. The skull melting process is simulated for the example of UO 2 . Under consideration of the given material properties it is shown that the skull melting method can be applied to fuse UO 2 .

Electromagnetic processing of molten copper alloys in the induction furnace with cold crucible

“…When melting metals in induction furnaces, a convex meniscus on the surface of the liquid metal is observed [17,18]. Figure 4 shows a picture at the surface of the investigated alloy during its melting in the ICCF furnace.…”
