    Blast furnace layer lining erosion problem based on inverse the heat conduction model

    • 摘要: 基于傳熱反問題,建立了高爐爐襯侵蝕過程的數學模型,確定了模型的邊界條件,并采用共軛梯度法將反問題分解為三個問題:正問題、靈敏度問題和伴隨問題進行求解.通過不同形狀函數的反演結果證明了其可行性,并分別研究初始猜測形狀曲線、測點數等對反演結果的影響.研究結果表明,初始猜測曲線的選取對反演結果影響很小,充分說明該方法不受初始猜測曲線的限制,具有較好的通用性.而測點數的選取對反演結果有一定的影響,測點數越多,曲線特征被捕捉的越好.但在保證得到曲線特征的前提下,較少的測點數也能得到比較滿意的反演結果,平均相對誤差控制在3%以內.
