The production of aluminium from alumina through the Hall-Héroult process requires carbon anodes as a key input. These anodes are made of calcined petroleum coke, coal tar pitch, and reusable anode butts. Anode production involves three critical stages: green anode manufacturing, anode baking, and anode rodding. Anode baking takes place in Anode Baking Furnace made of high Alumina Refractory Bricks inside a Concrete casing. This paper investigates the challenges and solutions associated with improving the performance of aging baking furnaces. As Anode Baking furnaces age, their efficiency tends to decline, leading to increased energy consumption, higher operating costs, and inconsistent product quality. This study identifies key factors contributing to the degradation of furnace performance, such as wear and tear of components, unstable control systems, and suboptimal maintenance practices. To address these issues, this paper proposes a comprehensive approach that integrates advanced diagnostic techniques, modern control technologies, and predictive maintenance strategies. |
