| Abstract Scope |
The anodes used for aluminium production are baked in order to reach the resistivity, mechanical resistance and reactivity adequate for the electrolysis process. The anodes are baked in pits that are usually separated from each other by fluewalls and headwalls made of dense refractory material. In 2017, an industrial prototype of the new generation anode baking technology was installed at the Bell Bay smelter with 6 sections converted to this patented technology. The headwalls were partially removed to allow a productivity increase by 15 % and gas consumption reduction by 30 %.
After the success of this first trial, the conversion of five additional 6-sections zones by the end of 2025 has been decided for Bell-Bay’s furnace. The use of prefabrication has been developed and implemented for the installation of the second generation of walls to:
1. shorten the construction duration and limit the production loss,
2. improve the ergonomics and safety for the construction workers and,
3. improve the overall brick assembly quality.
This paper reviews the process that led to an optimized second NG zone construction through prefabrication. |
