A Cells Repair Technology Applied Research In Aluminum Cell Mass Resume Production Construction After Shutdowned

Prebaked anode aluminum cells are the core equipments of modern aluminum production.General electrolyzer equipped with a number of units from 100 to 300 on electrolysis series,the event series power outage,disaster or operational need to shut down part of the cell to stop the large-scale production or stop groove:stop one-half,one-third of the number of slots or all slots stop.Re-engineering of large-scale resumption of production after the stop slot include clear groove,groove repair,technical innovation and start firing like.This paper describes the principles and the background history of the development of production,large-scale pre-baked anode aluminum reduction cells stop groove analysis basis,to an enterprise 330KA prebaked anode aluminum reduction cell for the study,collect literature data analysis this type of electrolytic cell technical characteristics of the structure,and to study the mechanism of some electrolyzers lined damaged,but also to repair the technical evaluation before the large-scale enterprise of a groove after stop as an example,the analysis of some situations cell damage and repair groove and technology strategies measures.Ching discusses the groove before restarting the cell mass after stopping groove conducted,planing,repair and many other slot groove repair technology,innovative applications of the crane pulling ripper waste cathode,not hanging upper tank removal and installation cathode cathode and other technologies,as well as the favorable opportunity to stop the use of large-scale repair groove slot,the popularization and application of Northeastern University professor reduction cells shaped cathode structure of aluminum reduction cell cathode carbon block new energy-saving technology,based on its technical drawing principles,further innovation and development of resistance to mosaic streaming technology to block cell repair and overhaul of small flat cathode cell,and profiled aluminum cell structure technology improvements,innovative applications cross-shaped configuration cathode cathode cell and other energy technology.Through this study,not only to improve the scale proposed for stopping the progress of the groove groove groove repair repair technology,but also for after stopping groove surplus employees of enterprises and more features,the choice can take advantage of the surplus manpower after stopping groove and ordinary workers can repair competent groove technology,namely crane pulling ripper waste cathode,not hanging upper tank removal and installation cathode cathode,but also in the promotion and development of energy-efficient cathode technology.Relying on a combination of these techniques,not only the full and effective use of human and material resources groove repair,as well as through the resumption of production engineering electrolyzer tank after restarting energy production and lay a good foundation.
