A process for online cut out of an aluminum reduction cell (pot) including the steps of leveling of the side beams of the reduction cell to around 150 mm; punching holes on both sides of the pot to ensure that the bath does not get overflow and ensure the dipping of the anodes through these punch holes; blowing air thoroughly all around the insulated shorted joints of all the risers to clean the joints from dust and large chunks of bath; applying lubricating oil to the shorted joint bolts to conform proper movement of nuts; breaking the side crust of all the four corner anodes; tapping the bath with at least one ladle; lowering the anodes such that there is no liquid overflow over the deck plate onto the catwalk; lowering of the beam by around 70 mm to 100 mm until the voltage falls below around 1.0 V-1.5 V at around 320 kA; loosening all riser bolts of the shorted joint of all the five risers using a pneumatic wrench after confirming that the anodes are dipped into the metal; removing insulated insert plates from the shorted anode riser joints and retightening all the five riser bolts using a pneumatic wrench and then taking the pot offline.
