为了延长高炉炉缸的工作寿命,某钢厂高炉(有效容积1 000m3)应用IT技术加强对高炉工作内型的跟踪与监测。通过建立计算炉缸侵蚀状况的数学模型,并利用该模型计算了高炉从2011年9月至2013年4月19个月的侵蚀状况,以此指导高炉操作。计算得到1 150℃侵蚀线的变化趋势。结果表明:该高炉的炉缸靠近死铁层平面的炉衬受到了侵蚀,在2012年12月达到了最大的侵入深度324mm;而铁口平面以上则处于较稳定的挂渣状态,其中7号风口在2013年3月形成最厚约240mm的渣壳。
In order to extend the working life of the blast furnace hearth, a steel mill blast furnace (effective volume 1000m3) application of IT technology to enhance the tracking and monitoring of blast furnace work. By establishing a mathematical model to calculate the erosion condition of the hearth and using the model to calculate the erosion status of the blast furnace from September 2011 to April 2013, it can guide the blast furnace operation. The trend of erosion line at 1 150 ℃ was calculated. The results show that the lining of the hearth of the blast furnace near the surface of the dead-iron layer has been eroded, reaching the maximum invasion depth of 324mm in December 2012, while the slag above the level of the iron mouth is in a more stable dross condition, in which the No. 7 outlet In March 2013 to form the most about 240mm slag skull.
