摘　　要：涟源钢铁集团公司80 t转炉采用高效吹氧技术,炉产量平均增加到100 t,供氧强度达到3.83m3/(t.min)。依据射流流场测定结果优化了氧枪喷头参数,改进了供氧和造渣制度,使年产钢量增加了25万t。在喷头设计中考虑了氧枪内管氧气流速,保证了用氧安全。在采用高效吹氧技术过程中,转炉炉衬寿命有所提高。The average heat size of 80 t converter at Lianyuan Steel was increased to 100 t with an oxygen supply intensity of 3.83 m^3/（t ·min） by optimization of lance parameters based on measurement of blow field of jetting, optimization of oxygen supply regime for slag formation and increase of charge. Thus, the yearly output was increased by 0.25 million ton. The oxygen flow rate was considered for lance designing to guarantee safety operation. The converter campaign has been increased sorhewhat by use of high efficiency blowing technique.
