对马钢A高炉(4000m~3)炉型管理经验进行了总结,分析了2014年初炉况失常过程中炉型管理的问题。A高炉炉型的管理主要是对炉体上部区域、下部区域和炉缸区域进行监控管理,主要经验:一是,强化原燃料质量管理、筛分管理,减少粉末入炉是保证合理操作炉型的基础;二是,日常操作中,炉型管理应作为重要的高炉生产管理制度;三是,炉型管理最终是实现煤气流较稳定,炉况顺行指标好的目标,而达到煤气流分布合理又反过来促进炉型的稳定。
The experience of furnace management of Masteel A blast furnace (4000m ~ 3) was summarized, and the furnace type management problems during the furnace failure in early 2014 were analyzed. A blast furnace furnace management is mainly the upper furnace area, the lower area and the hearth area monitoring and management, the main experience: First, to strengthen the quality of raw fuel management, screening management, reduce the powder into the furnace is to ensure that the operation of a reasonable furnace The second is that in the daily operation, the furnace management should be regarded as an important blast furnace production management system. The third is that the furnace management finally achieves the goal of a relatively stable gas flow and a good furnace forward index, Conversely, to promote the stability of the furnace.
