Model for Prediction of Erosion Profile of Hearth and Bottom of Blast Furnace
-
摘要: 基于對爐缸爐底襯磚破損機理的分析,采用有限元法建立了爐缸爐底侵蝕判斷數學模型。該模型用于推定爐缸爐底的1150℃等溫線(侵蝕參考線),并結合知識庫中的操作知識對護爐操作進行指導,以維護合理的操作爐型.Abstract: A model for prediction of erosion profile of the hearth and botlom of a blast furnace is established based on the analysis of the erosion mechanism of the hearth and bottom of the blast furnaces. The 1150℃ isotherm as a reference profile of the erosion of the hearth and bottom was calculated with the finite element method. The optimal working profile of the hearth canbe made by the model combined with the operative indication by the knowledge bases.
