The research to the method of breakdown diagnosis and prediction in aluminum electrolysis process

The breakdowns in aluminum electrolysis have great effect on the quality and quantity of aluminum and cause great waste of electricity. This paper presents a new method to predict and diagnose the breakdowns, which takes the advantage of discrimination and parameter prediction theory. This new method is easy to realize in the computer control systems; this has great significance in improving the quality and quantity of aluminum and in saving the electricity.
