Abstract
1537248 Smelting furnaces; cooling arrangements OUTOKUMPU OY 5 Dec 1975 50033/75 Addition to 1507941 Heading F4B In a flash smelting furnace wherein a suspension of finely divided sulphide or oxide and sulphide ore and/or concentrate in air and/or oxygen is fed to the upper end of a vertical reaction shaft 1 through an inlet 3, the interior of said vertical shaft 1 is provided with a forced circulation water cooling system for stabilizing the temperature of the downwardly directed suspension, the surface of said cooling system, being covered with an insulating layer of solidified material consisting of matte and slag components resulting from the smelting of the ore suspension within the shaft. The amount of heat removed from the shaft via the cooling system is dependent on the thickness of the solidified material layer which in turn is dependent on the reaction heat or temperature within the shaft. Smelted material leaving the bottom of the shaft enters the melt 5 within a horizontally extending reverberatory furnace 2. Heat is supplied via burners X and Y at the start of the smelting process. Waste gases leave the furnace through a flue stack 7, Fig. 2, which is provided with a device (not shown) for removing entrained residual material therefrom. The reaction shaft 1 may be subdivided into a plurality of vertically extending side by side reaction zones 6 as shown in Fig. 2, the boundaries or walls of said zones being defined by water cooling pipe systems 4.
