A temperature model for hot rolled plates during accelerated cooling

摘要: 介紹了一個采用有限差分法開發的溫度模型.該模型可預測熱軋鋼板在冷床加速冷卻時橫斷面的溫度變化,算法的精確性得到商業有限元軟件包的驗證.模型中考慮了實際生產中鋼板在空氣中、水平流區、水紊流區的溫度演變,同時還可耦合實測的熱物理參數進行計算,這有助于提高模型的精確度.Abstract: A thermal model developed by means of the finite difference method was adopted to predict the temperature distribution across the thickness of steel plates. The accuracy of this model was validated by the commercial finite element package FEMLAB. The heat transfer of hot plates was considered in this model when cooled in air, laminar water flow, and turbulent water flow. Furthermore, this model coupled the measured thermal physical parameters so as to improve its accuracy.
