FIELD: metallurgy.
SUBSTANCE: facility consists of shelter and aspiration hood made from shields secured on beams of frame. The frame of the aspiration hood is fastened to beams of the shelter frame. Shields on the beams of the aspiration hood frame and on the beams of the shelter frame are movably connected with process gaps of 20-30 mm. The facility is equipped with straps movably attached on shields by pins attached to shields; the straps overlap the said gaps.
EFFECT: raised efficiency of recovery of non-defined emissions from metallurgic installation.
