摘　　要：利用CFD软件对首钢水城钢铁(集团)有限责任公司100 t转炉进行了三维三相流数值模拟。模拟结果表明由于新氧枪产生氧气射流的冲击,熔池中的冲击面积和冲击深度比原氧枪有所提高。新氧枪搅拌能力好,可以促进钢液中的传质、传热,加快冶炼节奏。为检验模拟结果,将新氧枪应用于水钢转炉冶炼,结果表明新氧枪搅拌能力强,脱碳速度快,而且吨钢氧耗、供氧时间和供氧强度都能满足炼钢生产需求。A three-phase and three-dimensional mathematical model has been established using a CFD software and then numerical simulation of the 100 t converter in Shougang Shuicheng Iron ＆ Steel Group Co. , Ltd. carried out with the model. The simulation results show that because of the impact of new lance jet both the impact area and penetration depth in the bath are increased. And the new lance in possession of good mixed ability can promote the mass transfer and heat transfer of liquid steel and accelerate smelting rhythm. To test the simulation results the new lance is used to the BOF steel- making of Shougang Shuicheng Iron ＆ Steel Group Co. , Ltd. Results show the lance is of stronger stirring ability and faster decarburization rate, and moreover the oxygen consumption per ton steel, oxygen supply time and oxygen supply intensity can meet the production demand of steelmaking.
