| titleOfInvention | Oxygen lance fixing device for oxygen bottom blowing furnace |
| abstract | The invention relates to an oxygen lance fixing device for an oxygen bottom blowing furnace. The oxygen lance fixing device for the oxygen bottom blowing furnace is characterized in that: a large flange sealing cover (3) is arranged on the lower side of an annular seal water cooling box body (2) of an oxygen lance area (1) for the oxygen bottom blowing furnace; a secondary square cover plate (4) is arranged on the lower side of the large flange sealing cover (3); a small cover plate (5) is arranged in the center of the secondary square cover plate (4); the center of the small cover plate (5) is integrally welded with an oxygen lance barrel (6); the large flange sealing cover (3) is connected with the annular seal water cooling box body (2) through a screw nut (7) and is connected with the secondary square cover plate (4) through a No. 1 bolt (8) in an extrusion manner; and the secondary square cover plate (4) is connected with the small cover plate (5) through a No. 2 bolt (9) in an extrusion manner. The oxygen lance fixing device solves the technical problems of complicated and difficult replacement of oxygen lances, has safety and convenience for operation, and short replacement time of the oxygen lances and cannot cause furnace temperature fluctuation of systems. |
