对武钢1号高炉炉墙结厚的原因进行分析,发现冷却设备严重漏水、入炉原料质量差以及调剂措施不到位是导致高炉炉墙结厚的主要原因。采用发展边缘煤气流、提高炉温水平、降低炉渣碱度、控制冷却强度、改善入炉原料质量、加净焦和锰矿洗炉等综合措施消除结厚,取得了较好的效果。
Analysis of the causes of the thick wall of WISCO No. 1 blast furnace found that the serious leakage of cooling equipment, the poor quality of raw materials into the furnace and the incomplete adjustment measures are the main reasons leading to the thick wall of blast furnace. Adopting the comprehensive measures of developing edge gas flow, raising the temperature level, lowering the basicity of slag, controlling the cooling intensity, improving the quality of raw materials into the furnace, adding net coke and manganese ore to wash the furnace, the knotting effect was achieved.
