摘 要:转炉高效吹氧技术包括提高转炉供氧强度和优化造渣操作。宝钢一炼钢300 t转炉供氧强度达到3.83 m3/(t·min),太钢、涟源、萍乡等中型转炉的供氧强度达到4.0~4.4 m3/(t·min)。采用此项技术可提高转炉钢产量8%~15%。多孔交错布置喷头设计、制作及供氧、造渣技术,可以满足转炉高效吹氧技术转让的需要。
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 4.0-4.4 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.
