Refining phase lance and method of refining molten iron using the same |
| abstract |
An upper lance for refining, having a main hole nozzle 11 and a sub hole nozzle 12 in a vertical downward or inclined direction at a lance tip, and a side portion of the lance at a position isolated upward from the tip. And a secondary combustion nozzle 13 in a horizontal or oblique downward direction, and inside the upper lance, a powder different from the solid oxygen source is supplied together with the oxygen-containing gas for blowing through the main hole nozzle; Or a first supply path for supplying an oxygen-containing gas for blowing through the main hole nozzle, a second supply path for supplying an oxygen-containing gas for secondary combustion through the secondary combustion nozzle; Having a third supply path for supplying a powder-like solid oxygen source together with a carrier gas through the hole hole, efficient oxidation refining is possible in oxidizing molten iron or molten steel. At the same time, it provides a phase lance for efficiently dissolving the attached skull of the converter type refining vessel. |
