The location and shape of hearth and bottom erosion line of blast furnace can be calculated by a two-dimensional model set up with the boundary element method,and the erosion station of the furnace lining is known in time.
采用边界元方法建立某一大型高炉炉缸炉底的侵蚀推测二维模型,能够推定高炉炉缸炉底侵蚀线的位置和形状,及时了解炉衬侵蚀状态。
It is indicated through the calculated erosion graph that erosion line at 1 150 ℃ is located in the fifth layer of carbon brick,that there is not big shape of "elephant foot",and that the erosion is quite normal.
通过对模型的计算,得到了炉缸炉底的温度场分布,从计算所得到的侵蚀图来看,1150℃侵蚀线位于第5层碳砖的位置,无明显的"象脚状"侵蚀,6号高炉炉缸炉底的侵蚀状况基本正常。
