This paper summarizes the low fuel consumption production of 3#blast furnace of Qingsteel under the condition of low quality charge.By controlling the powder in the furnace,optimizing the mixing of the upper and lower parts of the blast furnace,controlling the reasonable temperature field distribution,controlling the slag composition and the furnace temperature,optimizing the operation in front of the furnace and so on,the long-term stable running of the furnace is real-ized under the condition of using low quality charge,and the purpose of cost reduction and efficiency increase is achieved.
