| Abstract: | The hearth accumulation reason for 2 500 m3blast furnace in Shuigang was analyzed, and the treatment process of hearth accumulation was summarized. Based on optimizing the charging system, blast furnace production gradually restored stability, technical and economic indicators were improved, with measures such as opening up the central gas flow and stabilizing edge gas flow, increasing the proportion of central coke, reducing the central coke angle, adding coke group, improving the blast furnace temperature, blocking the tuyere, switching long tuyere, and washing the blast furnace with the manganese ore and fluorite. |
