Title: Inclined vibrating kiln - transferring hot pre-reduced material direct to smelter out of contact with air
Inventor: SINDELAR GUENTER DIPL ING DR I
IPC: C22B5/16
Filed: 1972-04-07
Abstract: Pre-reduced, finely crushed ore, is fed direct from the reducer to the smelting furnace via a vibrating inclined kiln. The heat is maintained by means of electrodes in the kiln and oxidn is prevented by blowing an inert gas upwards through the charge and out at the discharge end of the kiln. Further refining can take place by vaporisation of unwanted elements which are carried off with the escaping gas and sepd. in a precipitator, or melting of the unwanted elements which are run off at the lower end of the kiln. By using the heat of the pre-reduced charge, less heat is required for smelting, so that shorter cycle time result.
