The coke preheating start-up of an aluminum electrolytic cell after overhaul was optimized from aspects of material filling,coke spreading electrode hanging,installation of soft links,installation of distribution tab,operation management in the roasting period,start-up of aluminum filling,and so on,then the anode conducts electricity evenly in a whole roasting period of electrolytic cell,the current distribution is 2.0～3.0 mV,three-steel temperature is lower than the set standards by 20 ℃,30℃,20 ℃ separately.
