摘要
FIELD: metallurgy.;SUBSTANCE: in arch of siphon there are implemented openings or windows for loading of carbon-bearing materials, partition with bottom window or windows for flow of melted slag into siphon is implemented in the form of common end wall for liquid-phase smelting shaft and siphon with electrode(s) and allows window or windows for fume extraction from under arch of siphon, located on level not higher than horizontal axis of top row of tuyeres of liquid-phase smelting shaft, siphon is outfitted by solid transverse partition, installed in its bottom part parallel to common end wall for liquid-phase smelting shaft and siphon at a distance enough for flow of required volume of slag melt from liquid-phase smelting shaft on surface of heated layer of carbon-bearing material, herewith solid transverse partition fully separates siphon from liquid-phase smelting shaft, and its top edge is located higher than horizontal axis of bottom row of tuyeres of liquid-phase smelting shaft.;EFFECT: invention provides decreasing of structure dimensions, utilising of all heat of effluent gas from siphon, decreasing of emissions amount of dioxide from siphon into environment.;1 dwg
