Self-produced steam sealing device at oxygen lance nozzle of converter

Abstract

The utility model relates to converter oxygen lance sealing technical field, the utility model discloses an embodiment provides a kind of self-produced steam sealing device at converter oxygen lance mouth, including converter oxygen lance, the circumferential surface of the converter oxygen lance is fixedly connected with sealing plug, the bottom of the sealing plug is fixedly connected with gas storage seat, the inside of the gas storage seat is provided with steam uniform distribution mechanism.In the utility model, when needing to seal converter oxygen lance, staff sends steam to the inside of gas storage seat, starts motor drive shaft rotation, drives gear A and gear B rotation, and then drives support shaft and fan blade rotation, uniformly blows steam into converter oxygen lance around to form high pressure barrier, ensure the sealing of the contact place of oxygen lance and furnace mouth, when furnace overhauls, add nitrogen by nitrogen gas pipeline, steam and nitrogen are used alternately, reduce steelmaking energy consumption, by the above technical scheme, the technical problem that steam cannot be uniformly sealed to converter oxygen lance mouth in relevant technology is solved.
