230kA铝电解槽物理场测试分析与技术条件优化

Test and analysis of the physical fields and optimization of the technical conditions of the 230 kA aluminium pots

通过铝电解槽物理场的综合测试,系统地给出电解槽的各区域能量损失、槽内磁感应强度的分布及流速分布,对铝电解槽的工艺技术条件合理性以及运行工况进行定量分析和科学评价,为提高铝电解主要技术经济指标,采取有针对性的技改措施提供科学依据。经过工艺技术条件的优化,实现最佳操作路线,有效提升了电解槽技术经济指标及综合效益。

The energy loss at various areas of the aluminium pots, the distribution of the magnetic flux density and the velocity of flow within the pots were systematically giveen by the comprehensive testing of the physi- cal fields of the pots. The paper made quantitative analysis and scientific evaluation on the rationality of the technical conditions and the running performance of the pots, which provided scientific foundation for having technical innovation and improving the main technical and economic indexes of the aluminium electrolysis. The general benefits and the technical and economic indexes of the pots were effectively improved by the optimization of the technical conditions and the realization of the best operation.
