中文摘要 |
讨论了钢铁工业连铸过程中结晶器内连铸坯凝壳形状的确定方法. 通过建立稳定温度场模型, 在现有观测条件下, 用边界变分方法给出了确定铸坯凝壳形状的辨识算法. 实验数据显示此方法是有效的. |
英文摘要 |
The method to determine the shape of solidification shell in the process of continuous casting of steel is studied.By establishing the model of stable temperature field,with the observation of first and second boundary value on the exterior of the ingot,the algorithm method to identify the shape of solidification shell is given with boundary variation in existing observation condition.Numerical test shows that the method is valid. |
