摘要
对马钢A高炉如何稳定操作炉型的生产管理进行了阐述。在原燃料质量波动大的情况下,A高炉的操作炉型不断变化,相对稳定性较差,通过对炉料结构、送风制度、煤气流分布、热制度与造渣制度、冷却壁与漏水和炉前出铁的调整与优化,操作炉型逐步合理,实现了炉况的稳定和生产指标的逐步改善。燃料比由最高的511 kg/t降至最低的492kg/t,煤比由最低的117kg/t提高至159kg/t,利用系数由最低的1.953提至最高的2.3。
The paper expounds the production management in stabilizing operating furnace profile in Masteel＇s BF A. The profile always changes along with great fluctuation of raw material and fuel quality. Thanks to reasonable adjustment and optimization in burden structure, blasting system, gas distribution, thermal system and slagging system, cooling stave and hot metal tapping operation, the operating furnace profile becomes stable gradually, resulting in stable fumaee status and gradual improvement of production index. The fuel rate drops from the highest 511 kg/t to the lowest 492kg/t, the coal rate increases from min. 117 kg/t to max. 159 kg/t and the productivity goes up from min. 1. 953 to max. 2.3.
