| Abstract Scope |
Traditional carbon anode quality control fails to detect critical internal defects, relying on destructive sampling and subjective visual inspection that compromise aluminium smelting efficiency. This study presents SERMA (Specific Electrical Resistance Measurement of Anodes), the first industrial system enabling non-destructive, full-body 3D electrical resistivity mapping of carbon anodes (green and baked) at scale.
Validation across 4,215 anodes revealed previously undetectable internal variations and unexpected correlations between green and baked anode properties. SERMA's quantitative mapping uncovered optimization opportunities that challenge conventional processing approaches, leading to novel defect prediction and furnace placement strategies.
The technology transforms quality control from reactive inspection to predictive assessment, demonstrating measurable improvements in material utilization and energy efficiency. SERMA represents a fundamental shift toward data-driven aluminum production, with implications extending beyond quality control to sustainable manufacturing practices. |
