摘　　要：马钢为提高高炉经济技术指标,通过对2号高炉采取强化原燃料管理、优化高炉操作制度、改进喷吹煤质量、全风温操作和控制一定的氧过剩系数等措施,使得2号高炉煤比得到大幅度提高,2012年9月份以后煤比达到160 kg/t以上,其中,2013年4月份煤比为182.7 kg/t。In order to improve the technical and economic indexes of blast furnace, Ma Steel has taken a series of measures, such as strengthening management of raw material and fuel, optimizing blast furnace operation, improving the quality of pulverized coal injected, adopting full blast temperature operation, and controlling the oxygen excess coefficient to a certain value, etc. Therefore, PCI rate is increased sharply which has been maintained at 160 kg/t above since September 2012 and even reached to 182.7 kg/t in April 2013.
