In the process of launching the electromagnetic rail guns (EMRGs), the erosion damage to the rail surface is mainly caused by the joule heat generated by the rail body resistance and armature-rail contact resistance as the current runs through the rail. According to the joule heat and the law of conservation of energy, this paper develops a formula to calculate the temperature rise of rail surface,...
Aimed to improve accuracy rate and time advance of the Anode Effect (AE) prediction in aluminum electrolysis cell, a new prediction method by means of the Generalized Regression Neural Network (GRNN) is proposed. The structure and advantages of the GRNN are introduced, then modeling the anode effect system of aluminum electrolysis cell by means of system identification based on the GRNN. The structure...
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...
