| Abstract Scope |
PT Indonesia Asahan Aluminum (INALUM) operates a closed-type anode baking furnace to produce carbon anodes for aluminum electrolysis. This study aims to optimize the anode baking curve by using actual anode temperature measurement data as the basis for fine tuning. Measurements were conducted in selected pits using thermocouples with data loggers to obtain the actual temperature distribution at each layer. The results showed temperature variations, including cases of underbaking in each layer, which affected the quality of RRO2, RRCO2, and anode thermal conductivity. Optimization was carried out by increasing the final baking temperature, extending the soaking duration, and adjusting other operational parameters such as fire progression. The implementation results showed an average improvement in RRO2 by 2.4%, a reduction in standard deviation by 1.21%, and an increase in Process Capability (Cp) value by 0.16. This optimization resulted in annual cost savings through the reduction of Net Anode Consumption (NAC). |
