| Abstract Scope |
Traditional carbon anode quality control relies on destructive sampling and subjective visual inspection, failing to detect critical internal defects that impact aluminum smelting efficiency. This study presents the first comprehensive industrial validation of SERMA (Specific Electrical Resistance Measurement of Anodes), a mobile non-destructive testing system generating detailed 3D electrical resistivity maps of both green and baked anodes. A one-year campaign at Emirates Global Aluminium tested 4,491 anodes, demonstrating robust measurement system capability and revealing internal defects invisible to conventional surface inspection. Analysis of over 2,000 green anodes identified distinct spatial resistivity linked to upstream process parameters, including vibrating time and kneader energy. Preliminary green-to-baked correlation studies showed promising relationships between green anode resistivity and final baked quality, with potential applications in predictive quality control and strategic baking pit placement. This work demonstrates SERMA's capability to transform anode manufacturing from reactive inspection to proactive, data-driven process optimisation. |
