ELECTRIC FURNACE FOR SLAG PROCESSING Russian patent published in 1997 - IPC

FIELD: nonferrous metallurgy. SUBSTANCE: electric furnace includes body, loading devices, electrodes combined in groups and connected to different poles of current source; one group of electrodes is mounted on hearth of furnace and is connected to negative terminal of current source and electrodes of other group submerged in melted slag are connected to positive terminal and are located in succession. EFFECT: increased capacity of furnace due to intensification of sublimation of volatile valuable components of slag due to combined zones of local overheating and bubbling at electrolysis of melt. 1 dwg, 1 tbl
