| titleOfInvention | Highly productive hot metal dephosphorization method |
| abstract | (57) [Summary] [Object] The present invention relates to a hot metal dephosphorization process and a decarburization process in a converter, and provides a highly productive hot metal dephosphorization process under high-speed oxygen supply. To do. In dephosphorization blowing in an upper-bottom blowing converter, a slit-shaped oxygen supply pipe having a concentric polygonal or concentric cross-section is provided, and 2 to 2 are provided in a part of a tip opening surface of the oxygen supply pipe. Ten shield plates are arranged, and the long side length B (mm) and short side length h (mm) of each of the tip opening surfaces separated by the shield plate are arranged. With a ratio B / h of 10 to 225 and a lance diameter of R (mm) (B × h) / R of 0.4 to 4, a top lance having a nozzle (N) is used. A highly productive hot metal dephosphorization method in which the oxygen supply rate F (Nm 3 / (min · ton)) is 2 to 4 without moving the lance tip including the points vertically with respect to the lance body. |
