Abstract The high efficient blowing technique includes increasing oxygen supply intensity and optimizing slag forming. The oxygen supply intensity on 300 t converters of No.1 steelmaking shop at Bao Steel reaches 3.83 m3/（t·min）, and at Taiyuan Steel, Lianyuan Steel, Pinxiang Steel and other steel plants, the oxygen supply intensity on medium converters is in the range of 4.04.4 m3/（t·min）. The productivity of converter can be increased by 8%15% with adoption this technique. The whole technique, including design and manufacture of lance nozzle with reasonable pacnolontenue of outlets, technique of oxygen supply and slag forming, has been developed by CISRI to meet the need of technique transfer.
