PT. Indonesia Asahan AluminiumAluminium, commonly known as Inalum SmelterInalum smelter, is a state-owned Indonesian company specializing in the production of aluminiumAluminium ingots, alloys, and billets. Ingots are classified into two categories, with those exhibiting lower Fe concentration (HPM) have a higher market price. Additionally, HPM potsHPM pots can be utilized to produce alloys. Some strategies are being implemented to increase the number of HPM potsHPM pots. These include, analysing key parameters such as metalMetals height, bath height, bath temperature, acidity, anodeAnode condition, Fe content in aluminaAlumina, and recycled material. The methods used include modifying the bar breaker teeth blade, reducing the anode change cycleAnode change cycle day, intensively monitoring bath height, establishing a localized HPM central section that focuses on achieving HPM potsHPM pots in certain potline, and standardizing the metalMetals height and pot acidity. This approach increased the HPM potHPM pots ratio fromFe 14% in 2017 to 20% in 2021.
