ABSTRACT:
The subject of the invention is a method of prevention of deep infiltration of copper into a lining of a smelting furnace for direct obtaining of copper from ore concentrates and copper ores.
The essence of the invention consists in that to the lower part of the hearth (2) of a furnace a cooling medium is delivered which is distributed in streams below a lining (1) of the furnace. Particular layers (1) of the hearth (2) have good heat conductivity, and in the lower part of the hearth (2) channels (4) are situated which serve for distribution of the cooling medium. The solution according to the invention prevents completely an excessive temperature increase of the furnace jacket.
