FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy, particularly to gas outlet channel of a converter. Gas outlet channel comprises converter gas cooler, in downtake gas duct of which below junction gas duct are arranged convective screens, preliminary cooling unit, scrubber, venturi tube and condensed moisture collection unit, which are installed on a common hopper, clean gas duct, smoke exhauster, smoke stack and connecting gas ducts. Downtake gas duct of converter gas cooler is connected to preliminary cooling unit by means of hydraulic compensator. Preliminary cooling unit and common hopper are equipped with means for draining excess sludge water. On clean gas duct there is a film moisture trap. Gas outlet duct is equipped with compensators of thermal expansion.EFFECT: invention enables to reduce number of unscheduled stops of gas outlet duct for repair.5 cl, 4 dwg |
