LANCE FOR BLOW-REFINEMENT IN CONVERTER |
摘要 |
A lance for blow-refinement in a converter comprises a primary nozzle generating a high-velocity, high-pressure primary oxygen jet, and an auxiliary nozzle generating an auxiliary oxygen jet. The auxiliary oxygen jet formed by the auxiliary nozzle has a velocity lower than the speed of sound. The auxiliary nozzle is configured so as to impede but not prevent oxygen flow therethrough. In the preferred construction, deceleration of gas-metal reaction induced by the oxygen jet. |
