摘　　要：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。To extend the campaign of hearth in a 1 000 ma blast furnace, IT technology was used to strengthen tracking and monitoring of internal dimensions of blast furnace. A mathematical model was developed to compute the erosion situation of the hearth. With the model, the position of erosion line was calculated from Sep. 2011 to Apr. 2013 to get the trend of 1 150 ℃ erosion line. The results showed that the hearth below the tapping hole level of the blast furnace was eroded, which reached the maximum depth of 324 mm in December 2012. The heart above the top-hole level was covered by slag, and the thickest slag shell of 240 mm was formed in the 7th tuyere in March 2013.
