摘　　要：莱钢3200m3高炉2014年在入炉综合品位55.32%的条件下,通过加强原燃料管理、开发煤气流控制模型、改善炉缸活性、加强高炉生产管理等措施,取得了利用系数2.456 t/(m3·d)、焦比340.5 kg/t、煤比175.4 kg/t、燃料比515.9 kg/t的良好技术经济指标,达到了高炉经济冶炼的效果。By strengthening the management of fuel and raw materials and the BF production, developing the gas flow control model,improving the activity of hearth and other measures, under the condition of charging comprehensive grade of 55.32% in 2014, the 3 200m^3 BF in the Section Steel Ironmaking Plant of Laiwu Steel realized economy smelting and achieved good technical and economic indexes. The productivity is 2.456 t/（m^3·d）.The coke rate is 340.5 kg/t, the coal rate is 175.4 kg/t and the fuel ratio is 515.9 kg/t.
