  • Chute with hazardous flame and fume control
    Patent number: 4231792
    Abstract: Air injectors are located in a ladle additive chute to eliminate the chimney effect created by the chute and hot gases present when a furnace is tapped. Air is supplied through openings about the chute below an open upper end, through which ladle additives are charged. The openings direct the air downward and inward of the chute and the air is supplied at a pressure and flow sufficient to prevent smoke, fumes and eruptive flames from rising through the chute when alloys are added to the metal being poured into the ladle.
