| Abstract Scope |
PT Indonesia Asahan Aluminum (INALUM) operates a closed-type anode baking furnace to produce carbon anodes for aluminum electrolysis. To improve baking performance, a process improvement program was implemented by measuring the actual anode temperature using thermocouples installed in different layers of pits #4 and #5. Results showed temperature distributions of 21°C in pit #5 and 30°C in pit #4, with average final temperatures meeting or exceeding the minimum 1150°C standard. Temperature gradients varied significantly—12–16°C/h in pit #5 and 17–20°C/h in pit #4—indicating uneven heat transfer. To address this, offset adjustments were applied to burners 2, 3, and 4, leading to improved thermal homogeneity. This initiative not only enhanced anode quality consistency but also contributed to optimized energy usage. The study demonstrates the importance of actual temperature monitoring in closed baking furnaces to ensure process control, product quality, and operational efficiency. |
