摘要
The invention relates to thermo-technical equipment for melting particulate material and may be used in an autogenous smelting of sulfidic raw materials in particular copper concentrate. Oven autogenous smelting of sulfidic raw materials for matte comprising the hearth, the housing with disposed therein melting section shaft type vertical shihtovokislorodnoy burner taphole for discharging matte electrothermal settling section, with electrodes immersed in the slag melt taphole for tapping slag and flue for removing gases and dust, which, according to the invention self-baking electrodes are provided, wherein three phase electrodes are located symmetrically at a distance of 120 ° from each other, and the fourth self-baking electro d, is set in the center between the phase electrodes with the possibility of displacement on the vertical axis. This furnace will enhance its performance, due to the acceleration of gravity separation of the slag and matte, to reduce copper loss in the slag, to improve process control performance. 2 ill.
