| 200kA prebaked aluminum reduction cell voltage swing of early prevention and treatment
Is bound to break the anode over the anode end of the formation of the palm, it will cause the anode current distribution of disorders, thereby increasing the voltage swing. * 26 * Light Metals 2003 5 200kA Prebaked computer intelligent control technology in the production of aluminum Chen Jinghui (Qingtongxia Aluminum Group III electrolysis plant, Qingtongxia 751603) Abstract: This paper introduces 200KA Prebaked electrolytic production of computer control technology and network information linked to surgery. Focuses on intelligent tank resistance control, concentration of alumina and slot intelligent tracing the status of information technology software application analysis and decision. 'The key tone: Prebaked; alumina concentration; slot resistance; intelligent tracing; computer control; information technology; CLC Kids in aluminum electrolysis: TP273.5 Document code: B Article ID :1002-1752 (2003) 05 O5 a o026 a scientific and technological development with the advanced production technology and pre-baked anode combination of computer technology has become increasingly close. Prebaked control the use of computer and network technology, data warehouse technology support, to achieve a pre-baked anode production process real-time monitoring, mathematical analysis,air jordans, remote control, slot status discrimination, expert reasoning, trend control, form a complete closed-loop system, but also has control of the stability and convergence. Qingtongxia Aluminum Group's third series of electrolysis plant using electrolytic tank 200kA prebaked aluminum craft, launched in 2001 put into operation, the formation of 135,000 t of electrolytic aluminum production scale. Automatic Control System of the cell as Distributed by the distributed control system, is divided into monitoring level, the current distribution level, three levels of intelligent control of slot machine control. Electrolysis assisted analysis system, fuzzy expert system in the management server,air jordan shoes cheap, put into operation, which constitutes a service management level, monitoring level, the functions of three of the electrolytic tank control machine production control system. Later, according to the needs of electrolysis,ugg stivali, relying on plant local area network, station put into operation in the electrolysis,ugg milano, the formation of the integrated control of pre-baked anode electrolysis 200kA computer intelligent control system. 1200kA Prebaked technical overview of computer intelligent control of distributed control with integrated control (Figure 1), by the server level, monitoring and management level, the local control level (intelligent slot control unit) component. Electrolytic production management data transmission via Ethernet,ed hardy, electrolytic production of real-time data transmission via CAN-BUS bus. Computing the control system to the main network switch as the central station, connected electrolytic production management network, production control network topology to the production unit, the working site; system can meet the network services, production management, site is running <electrolytic analysis and decision aid System \conditions, to maintain high economic performance provides a good technical support. 1.1 Management service level by the two servers. Monitoring and management in accordance with the machine the next level of data transfer protocol, real-time data transmission electrolysis and historical data for the electrolytic production management network, fuzzy expert system, electrolysis assisted analysis system, electrolysis furnace Analysis workstation system provides other benchmark to judge the groove state trends in historical data, is the electrolytic production control system data warehouse. 4.3 due to the voltage swing to the tank caused the tank temperature and high voltage swing to add AlF3 a long time, some higher voltage. Inevitably lead to the bath temperature rise - according to statistics, the voltage swing when 500min / day or more. In lOOmV swing around, make the bath temperature rose 8 ~ 12 ��. Do not analyze the reasons for the blind to the tank to add AlF3, the result that a substantial increase in superheat, excess heat will help melt furnace, counter-productive. 4.4 emphasis on operational quality. The neglect of the technical conditions of operational quality is important, mainly in the daily work is strictly act in accordance with the rules. The status of its large impact groove groove Board Received: 2003 a 26 a Ol, and is a strategic factor; and technical conditions with inappropriate trough. Small disturbance can lead trough the disease, even when the quality of re-operation is also difficult to make fine tank conditions to improve. Only with good technical condition. Since the trough of the balance will be enhanced to the greatest degree of patience outside interference, it is a strategic factor. Technical conditions should be placed on the operational quality is more important than status. References: l�� ��Yin Ensheng with.
