| Abstract Scope |
The pot relining method at INALUM is divided into 2 methods, namely the full repair and partial repair. The partial repair method has a weakness, when a cracked cathode block is found, this method cannot be implemented and continue with full repair method. Improvement was made in 2021 to replace several damaged cathode blocks with new cathode blocks, combine the new cathode blocks with the old ones and continue the partial repair work instead of having to switch to full repair work. The application test of the new partial repair method was carried out on pot R-117. The average operational parameter from the test pot shows a fairly similar performance to the reference pot. The pot managed to get an additional 2 years of age and get a cost saving of 109,725 USD per pot. Moreover, the application of new partial repair reduces potential spent pot lining until ±50 ton/pot. |
