Abstract

The invention relates to the field of ferrous metallurgy, in particular to the design of the oxygen lance for blowing the converter bath from the top with two types of jets. The lance comprises a head with peripheral supersonic nozzles and the central nozzle placed therein, which central nozzle has a cylindrical part and swirler mounted in the front of it with the ratio of total passage area of ​​the swirler channels to the total area of the critical sections of the peripheral nozzles is equal to 0.05-0.25, at that the ratio of the length between a swirler and the outlet section of the central nozzle to the inner diameter of the cylindrical part is 1.5-7.5. The central nozzle can comprise an initial part that is made in the form of the truncated cone divergent or convergent with an apex angle of no more than 12 degrees. The invention provides the increase of efficiency of CO-containing gases afterburning, improving the organization of diversion of the vortex jet of the additional oxygen, the heat balance of the slag smelting process in the converter, advanced management of the steelmaking process, improving the sustainability of the source area of the central nozzle and the lance in general, and reduces the cost of steel, which is produced in the converter.
