Research and Simulation for Liquid Steel Temperature Distribution in Pattern Recognition Method

研究钢包内钢液温度分布准确辨识的方法。在冶金过程中,钢包内的钢液温度具有较强的流动性和随机性。利用传统算法进行钢包内钢液温度分布辨识,将造成钢液流动时的温度差异较大,最终影响了钢包内钢液温度分布辨识的准确性。为了避免传统算法的缺陷,提出了一种基于单元内部场差值算法的钢包内钢液温度分布辨识方法。建立热传导微分方程,用来描述钢包内部钢液热传导的情况,从而为钢包内钢液温度分布辨识提供基础数据。利用单元内部场差值算法,建立温度分布辨识方程,从而实现钢包内钢液温度分布辨识。实验结果表明,利用本文算法进行钢包内钢液温度分布辨识,能够极大的提高辨识的准确性,从而满足实际冶金作业的需求。

The paper proposed a difference algorithm based on the unit internal field of temperature distribution of mohen steel in ladle identification method. Heat conduction differential equation was used to describe the internal liq- uid steel ladle heat conduction, thus provided the foundation for the temperature distribution of molten steel in ladle i- dentification data. Unit internal difference algorithm was used to establish the identification equation of temperature distribution, so as to realize the temperature distribution of molten steel in ladle. The experimental results show that the algorithm presented in this paper can identify the object temperature distribution of molten steel in ladle, which greatly improves the accuracy of recognition and meets the needs of actual metallurgical operations.
