Abstract:
1. A method for reducing oxidic slags and dusts using an inductively heatable coke bed extending in an axial direction and having a temperature gradient, comprising the steps of: drawing off reaction as by suction in at least one axial region of the coke bed positioned below a head-side induction body arranged in a vicinity of a cold charging end of the coke bed, wherein said drawing off of the reaction as is performed from two or more axially consecutive annular spaces arranged in the axial direction of the coke bed, and tapping a metal regulus and slag melt at a tap end of the coke bed, wherein said head-side induction body is operated at a frequency of 20-120 kHz, and a tap-end induction body arranged in a vicinity of the tap end of the coke bed is operated at a frequency of 1-10 kHz.
