| Abstract Scope |
PT Indonesia Asahan Aluminium (INALUM) operates a carbon plant that produces baked anodes for aluminum electrolysis. During 2025, the plant experienced an increase in baked anode crack rate. Statistical analysis identified Green Anode Density (GAD) variation as a key factor contributing to crack formation. Improvement efforts focused on reducing GAD variability through process optimization. Two approaches were evaluated, increasing mixing energy through kneader modification and adjusting the Eccentric Counterweight (EC) angle of the vibroformer. Industrial trials were conducted using several EC angle configurations. The results showed that increased mixing energy improved density uniformity, while optimization of vibration force reduced GAD variability and baked anode crack. Among the tested configurations, an EC angle of 130° produced the most stable GAD distribution and the lowest baked anode crack rate. These findings demonstrate that optimizing mixing energy and vibroforming parameters is an effective strategy for improving anode quality and reducing baked anode crack. |
