Process for the physical separation of the metallic phase from the slag in an induction furnace

摘要

The invention relates to a method for the separation in an induction furnace of a metallic phase and scoriae in a crucible 1 essentially transparent to an electromagnetic field. The method consists of subjecting materials in a first zone 14 to an electromagnetic field of frequency enabling the direct coupling of the inductor 10 with the scoriae, then in a second zone to an electromagnetic field of reduced frequency enabling, under the effect of the centripetal forces produced, the assembling of the metallic phase 28 in the axial region of the crucible.
