During the production of aluminium from conventional prebaked Hall Héroult electrolysis cells, anodes have to be replaced on a regular basis. The anode rod assemblies, submitted to multiple heating/cooling cycles, tend to deform over time. Moreover, attacks from HF gas and liquid bath erode the stubs to a different extent at each cycle. The stubs thus require regular inspection to determine if they need to be repaired. Repair costs are often very expensive and difficult to follow and forecast. In 2016, STAS commissionned its new ASIS3D for the 3D analysis of stubs in any configuration (like hexapods). All anode rods in the rodding shop are automatically inspected in less than 30 seconds. A work order is automatically generated for each anode rod that needs to be repaired, after which it is registered in the database and printed on the anode rod. This paper describes the industrial performances of the ASIS3D.
