摘　　要：随着环保限产,一烧1^(#)、2^(#)烧结机退出生产序列后,烧结矿产量日趋紧张,高炉配加大比例球团矿已经成为炼铁发展的新趋势。本次试验过程中5^(#)高炉通过对料面规整、调整中心焦量和料段排料顺序、优化风口参数和进风面积、增加炉缸热量储备、调整和控制炉渣的碱度,在操作上主动应对球团矿配比增加后炉况出现的各种变化,高炉炉况稳定顺行。包钢大比例球团矿的炉料结构在1500 m^(3)级高炉上成功实现了冶炼生产,球团矿使用比例达到了52%,燃料比稳中有降。With the environmental protection and production limitation,the output of sinter is becoming increasingly tense after 1^(#)and 2^(#)sintering machines in 1^(#)sintering workshop are not in the production sequence as well as the addition of large proportion of pellets into blast furnace has become new development trend of iron-making.During this test,5^(#)blast furnace is with trouble free operations through regulating charge level,adjusting central coke quantity and discharging sequence of feed zone,optimizing parameters of tuyere and area of inlet air,increasing heat reserve of hearth,adjusting and controlling basicity of slags as well as actively coping with various changes of furnace conditions after increase the proportion of pellets.The smelting production is successfully realized in the 1500 m^(3)blast furnace of Baotou Steel with structure of furnace charge of large proportion of pellets and use ratio of pellets reaches 52%,so the fuel ratio is stable with a slight decline.
