宣钢2 500 m3高炉,上料为皮带上料,炉顶为并罐无料钟炉顶,其自动控制系统采用ABB公司的AC800F系统,该系统控制稳定且故障率低。其炉顶自控系统在投产初期,基本能满足生产的需要,但随着高炉生铁产量、质量的提高,炉顶原有的控制方式已无法满足正常的生产需要,为此对2 500 m3高炉炉顶自控系统进行了优化与创新,为高炉的稳产和高产奠定了基础。 Xuanhua 2 500 m3 blast furnace, feeding the material for the belt, the top of the furnace and bell-free top of the bell, the automatic control system uses ABB’s AC800F system, the system control and low failure rate. The furnace roof control system in the initial production, the basic can meet the production needs, but with the blast furnace pig iron production, quality improvement, the original roof control methods have been unable to meet the normal production needs, for this 2 500 m3 blast furnace Top automatic control system was optimized and innovative, laid the foundation for the stable and high yield of the blast furnace.
