SERMA - Full Volume Anode Internal Scanning System Patented

Specific Electrical Resistivity Measurement of Anodes

This patented technology offers 100% 3D scanning and mapping of green anodes and baked anodes for complete anode quality characterization. Fully developed by Dynamic Concept, this advanced solution enables comprehensive anode characterization and precise analysis of internal properties, including anode resistivity, to optimize anode performance and process reliability.

Challenges

Internal Anode Defects (Porosity, Cracks, Pitch Segregation)

When undetected, these defects can lead to higher scrap rates, less consistent cell performance, increased operating costs, and greater environmental impact.

Solution

Measure Electrical Resistivity Across 100% of the Anode Volume

Through measurements performed across multiple perpendicular planes, this comprehensive analysis accurately detects and locates internal variations that may impact anode quality and performance during electrolysis

Electrical resistivity measurement from top to bottom and left to right
Precise mapping of areas with high resistivity
Identification of internal defects that may affect electrolysis performance and overall anode reliability

Measurable Benefits

Advanced internal defect detection: Identification of resistivity variations and anomalies that are invisible through traditional visual inspection of anodes used in aluminum production.

Enhanced process understanding: 3D resistivity mapping provides a clear view of the spatial distribution of process variations, enabling optimization of production parameters upstream.

Stronger anode quality control: Precise characterization of green and baked anodes improves quality monitoring and enables faster, data-driven decision-making.

Improved baking process: Better control of process parameters helps produce more consistent and higher-performing baked anodes.

Reduced scrap rates: Early detection of defects helps minimize the rejection of conforming anodes and improves production yield.

Improved electrolysis performance: Greater anode consistency contributes to more stable cell performance during electrolysis.

Reduced operational and energy costs: Process optimization and reduced losses help lower energy consumption and associated operating costs.
