【摘要】 用软件 CFX5.7.1对电弧炉炼钢用集束射流氧枪射流特征进行了数值模拟,结果表明,集束射流氧枪射流长, 射流集中衰减慢.分析了北京科技大学集束供氧系统工艺流程及主要工艺参数,及其在通化钢铁公司的使用情况.通过使用 USTB 集束供氧系统,通化钢铁公司第一炼钢厂的电弧炉平均电耗由370 kW·h/t 降低到190 kW·h/t,冶炼周期从65 min 缩短到49min,电极消耗从1.5kg/t 减少到1.3 kg/t,氧气消耗从42 m~3/t 增加到65 m~3/t,碳粉消耗从4.5 kg/t 增加到14.5 kg/t.更多还原

【Abstract】 Numerical simulation of jet flow of coherent oxygen lance for arc furnace steehnaking was carried out by CFX5.7.1 software. The results showed that jet flow of coherent oxygen lance was long,concentrated and anti-attenuation.The main process parameters of coherent oxygen jet system belonging to University of Science and Technology Beijing were introduced,and its application status in Tonghua iron and steel enterprise was described.Due to application of coherent oxygen jet system belonging to University of Science and Technology Beijing,in the first steel making factory of Tongsteel the average electric power consumption of arc furnace decreased to about 190 kW.h/t from 370 kW.h/t,smelting circle decreased to 49 min from 65 min,electrode consumption decreased to 1.3 kg/t from 1.5 kg/t,oxygen consumption increased to 65 m~3/t from 42 m~3/t,and carbon powder consumption increased to 14.5 kg/t from 4.5 kg/t.更多还原
