摘　　要：通过提高精料水平、提高喷煤比、降低铁水含硅、优化高炉操作制度等措施,实现了铁前原燃料的合理配置,高炉入炉焦比逐步降低;2012年达到354 kg/t,比2011年减少30 kg/t。With measures： improving concentration level, increasing coal injection ration, reducing silicon content in hot metal and optimizing operation system, the reasonable proportioning of raw and fuel material before iron -making is realized, the coke ratio into the blast furnace gradually reduced to 354 kg/t in 2012, 30 kg/t lower than 2011.
