摘要
控制冷却在轧制生产中很大程度上决定了最终产品的力学性能。介绍一个采用有限差分法开发的温度模型:该模型可耦合实测的物理参数,为一维非对称非线性热传导方程;考虑了钢板在空气中,高压水及平流层水中不同热交换;其独特之处就在于可直接输入材料的物理参数。实测结果证实,该温度模型的精度较高,有广泛的应用前景。
An asymmetric 1D thermal model developed by the means of a finite difference method has been adopted to predict the temperature distribution across the thickness of steel in the run-out table. This model has considered the heat transfer of the hot plate when it is in air, high pressure water and still water. Due to its unique ability of reading physical parameters directly, compared with production data, it is proved that this model can give reasonable agreement.
