Method for diagnosis of damage of aluminum electrolytic tank

Abstract

The invention provides a method for diagnosis of damage of an aluminum electrolytic tank, wherein the method includes the following steps: establishing normal data of a normal production period of the aluminum electrolytic tank; measuring diagnosis data whether the aluminum electrolytic tank is diagnosed to be damaged or not; utilizing the data measured in the former two steps, and calculating correction data; and analyzing the correction data, and determining whether the aluminum electrolytic tank is damaged and determining a specific damaged position. Compared with the related technology, the method for diagnosis of the damage of the aluminum electrolytic tank is easy to realize, can accurately determine the damage position of the aluminum electrolytic tank, ensures the electrolytic safety, and achieves energy saving and efficiency increasing.

Description

【Technical field】 [0001] The invention relates to the technical field of aluminum electrolytic cells, in particular to a method for diagnosing the damage of aluminum electrolytic cells. 【Background technique】 [0002] In order to ensure the safety of the electrolytic series and achieve energy saving and efficiency enhancement, the electrolytic aluminum industry urgently needs to accurately judge the location of the damaged point of the electrolytic cell, so that it can be effectively repaired after the damage and stable operation and maintenance after repair, so as to prolong the life of the cell. [0003] The traditional damage groove location measurement is a late monitoring method. When it is found that the content of iron and silicon in the aluminum liquid has increased, the temperature of the steel rod is measured by the temperature difference method to initially judge the damaged part, and then the bottom of the furnace is manually probed to finally determine the size ...

AI Technical Summary

Problems solved by technology

There are many deficiencies in this diagnostic method: first, there are many factors that cause the increase of iron and silicon content, it is difficult to accurately diagnose whether the increase is caused by the damage of the electrolytic cell, and it is also impossible to find the specific damage location; second, in the early stage of damage, The local temperature difference is not obvious, and it is difficult to find the damage point; the third is that manual exploration of the furnace bottom is greatly affected by human factors such as experience, and the success rate is low

If the electrolytic cell is damaged but is not detected in time, there will be major safety hazards such as furnace leaks; if the electrolytic cell is controlled or stopped once the iron and silicon content rises, it will waste huge manpower and material resources, causing unnecessary necessary economic loss
