宝钢1号高炉炉缸侧壁温度最高超过500℃,并有3处残厚处于500~700 mm的危险区域。重点分析了炉缸侵蚀的原因,认为主要是焦炭质量下降、高炉顺行状况不稳定、炉缸局部传热不畅等。提出了延缓1号高炉炉缸侵蚀、实现长寿的对策:一是,改善入炉焦炭质量;二是,减小并罐布料偏析,改善高炉顺行;三是,定期压浆维护,增强炉缸冷却强度。
Baosteel No. 1 blast furnace side wall temperature of the highest over 500 ℃, and 3 residual thickness in the 500 ~ 700 mm of the danger zone. Focusing on the analysis of the reason of the erosion of the hearth, the main reason is that the quality of coke is declining, the condition of the blast furnace is not steady and the local heat transfer of the hearth is poor. Proposed to delay the blast furnace hearth erosion, to achieve long-life countermeasures: First, to improve the quality of coke into the furnace; the second is to reduce and tank fabric segregation to improve the smooth blast furnace; Third, the regular grouting maintenance, enhanced hearth Cooling intensity.
