In aluminum electrolytic process, the performance evaluation of aluminum production management play an important role in improving the economy and objectivity of management. It's very necessary to construct an assessment system. In this paper, a performance evaluation methodology for aluminum electrolysis is proposed. An optimization model based on multiple weights combination and interval weights...
The concentration of alumina in the electrolyte is of great significance during the production of aluminum; it may affect the stability of aluminum reduction cell and the current efficiency. However, the concentration of alumina is hard to be detected online because of the special circumstance in the aluminum reduction cell. At present, there is lack of fast and accurate soft sensing methods for alumina...
An online detecting system of aluminum electrolytic anode current is designed. This system adopts the architecture of state machine based on queue to solve a problem of real time response between data communication and human-computer interaction by using multithreading. It can detect real-time current distribution of anode rod and to deal with abnormal alarm. Under each work condition of aluminum...
The anode current is a very important parameter in the aluminum electrolysis production. However at present, manual measurement is still being used in the aluminum industrial. There are some shortcomings, such as low measurement precision, data lag, etc. This approach can't meet the requirements of the modern management and production for aluminum electrolysis. Based on the principle of anode rod...
