摘 要：研究建立了电弧炉炼钢过程能量优化模型,提出了供能决策顺序为"先氧后电",实现供氧和供电的能量优化配置,能量供应接近理论需求值。在天津钢管公司150 t电弧炉炼钢生产中进行了工业试验,并且与原工况和模拟计算的结果进行了比较分析,研究表明:能量优化方法取得了较好的生产效果,其各项指标的平均值为:冶炼周期为49.5 min,出钢量为141.2 t,冶炼电耗为314.3 kW·h/t,氧气消耗为41.0 m3/t,氧气利用率为87.7%,金属收得率为88.5%。
Abstract: In order to balance between the power supply and the theoretical demand value in electric arc furnace steelmaking process,the optimal energy model was established.Based on the policy making order that was "first oxygen,second electricity",it could achieve energy optimal distribution about oxygen and power supply.The industry experiment had been made in the 150 t EAF steelmaking process in Tianjin Pipe Group.The results were compared and analyzed with original operating condition and simulation,and good production efficiency had been made.The tapping to tapping time was 49.5 min,the tapping quantity 141.2 t,the smelting electricity consumption 314.3 kW·h/t and the oxygen consumption 41.0 m3/t on average.The oxygen utilization rate reached 87.7% and the recovery of metal 88.5%.
