Thermal deformation of HVC work roll in hot strip rolling
-
摘要: 以HVC工作輥為研究對象,采用二維交替方向差分法建立了工作輥溫度場模型,可對任意時刻工作輥溫度場分布和熱輥形進行仿真,計算時間能夠滿足在線應用且具有絕對穩定性.通過現場實測數據與模型計算值比較,吻合較好,驗證了模型的準確性.Abstract: A temperature field model of work rolls is established with an HVC work roll as the object of study by a method of two-dimensional alternating direction finite difference. The model can be used to simulate the temperature field and thermal contour of work rolls at any time, and its computing time meets the online requirement, with absolute stability. The calculated values are in good agreement with online measured data, indicating the accuracy of the model.
