System synopsis

　　The system is mainly used for electrolytic groove shell temperature automatic detection and primary crystal temperature detection. Realizing accurate judgement about relationship between electrolytic temperature, groove shell temperature changes, side of the groove shell formation, electrolysis temperature, molecular ratio, voltage, series current and other parameters with the thickness of groove shell side．Predicting the development trend of aluminium cell. In the cell's life cycle, Understanding the formation and rate of each side of the groove shell during different time, the relationship between the technical conditions and indicators with the thickness of groove shell side during normal production.
　　The system is be beneficial to the stability of electrolytic technology control．Ensuring the smooth operation of electrolytic production, and Realizing the maximum current rate. It will be a very important action to improve the technical and economic indicators of aluminium electrolytic production.

Function Features

1. The system uses third class computer-controlled topology, realizes real-time, online, automatic detection the both sides of aluminium cell tank shell the both ends of groove shell, the anode steel bars and other parts temperature changes.
2. The system has strong anti-electromagnetic interference ability and strong environmental adaptability, adapting to continuous work under industrial environment.
3. High temperature endurance of measuring temperature components, firm paste.
4. The system is open and temperature gauge alarming functions, when the electrolytic cell shell temperature anomalies will be issued tips, take corresponding protection measures.
5. The system PC software has a simple man-machine interface, facilitate information-processing and database management.
