摘　　要：结合安龙的炼铁高炉实际生产,对安龙高炉进行了一系列攻关.。如富氧大喷吹相结合,提高精料水平,提高风温。在原有单纯喷吹无烟煤的基础上,改进制粉工艺,实现了烟煤无烟煤混喷吹。2006年的上半年与2004年相比,焦比降低了135 kg/t,煤比提高了68 kg/t。The renewal of blast furnace at AN LONG were conducted A series of measures were adopted such as improving concentrate quality, ,blasting with rich oxygen and enhancing blast temperature. On the base of blasting anthracite coal simply, the pulveiled coal preparation is improved. Nevertheless, the mixing blasting technique of bituminous and anthracite i is realized. The coal ration is increased 68 kg/t and the coke ration reduced by 135 kg/t.
