The Effect of Addition of ALF3 on Bath and Molten Temperature at PT. Inalum Kuala Tanjung

Introduction

PT. Inalum Kuala Tanjung is a leading aluminum production company that plays a crucial role in the global aluminum industry. The company's primary goal is to produce high-quality aluminum products while maintaining efficiency and cost-effectiveness. However, the production process is not without its challenges, particularly when it comes to maintaining the optimal levels of ALF3 (aluminum fluoride) in the bath. In this article, we will discuss the effect of adding ALF3 on the temperature of the bath and molten produced at PT. Inalum Kuala Tanjung.

Analysis of the Effect of ALF3 on Bath Temperature

The importance of maintaining ALF3 levels within the specified limits is very crucial in the aluminum production process. Aluminum fluoride functions to reduce alumina melting points and increase the efficiency of the electrolysis process. When ALF3 levels are too low, bath temperature can increase, which has the potential to cause an increase in energy consumption and reduce the efficiency of aluminum separation from alumina. Conversely, if the ALF3 level is too high, the temperature of the bath can decrease, causing inefficient reactions and more slag formation.

This temperature fluctuation not only affects the quality of the aluminum produced, but can also impact the reliability and safety of operational pots of reduction. Unstable electrolysis processes can cause damage to the equipment and increase operational costs. Therefore, ALF3 proportion settings are very important to maintain the stability of the process, which in turn will increase productivity and cost efficiency at PT. Inalum Kuala Tanjung.

Observations and Analysis Conducted at PT. Inalum Kuala Tanjung

In observations and analysis conducted at PT. Inalum Kuala Tanjung, it was found that there is a percentage of excess ALF3 (aluminum fluoride) that is not in accordance with the standard, which is 9.9% ± 1.5%. In Pot R-111, R-117, and R-121, each of the excess percentage is 7.1%, 13.1%, and 15.1%. This incompatibility affects the fluctuations of bath temperature that is not in accordance with the expected standards. This increase or decrease in temperature is caused by ALF3 content in a bath that is too low or too high. Therefore, it is necessary to set the ALF3 income into the reduction pot so that the aluminum reverse reaction becomes alumina or slag formed at the bottom of the pot does not occur.

The Importance of Maintaining ALF3 Levels

Maintaining ALF3 levels within the specified limits is crucial in the aluminum production process. The optimal level of ALF3 is essential to ensure that the electrolysis process takes place efficiently and that the quality of the aluminum produced is high. If the ALF3 level is too low, the bath temperature can increase, causing inefficient reactions and more slag formation. Conversely, if the ALF3 level is too high, the temperature of the bath can decrease, causing inefficient reactions and more slag formation.

The Impact of Temperature Fluctuations on Aluminum Production

Temperature fluctuations can have a significant impact on aluminum production. Unstable electrolysis processes can cause damage to the equipment and increase operational costs. Therefore, it is essential to maintain the stability of the process by setting the ALF3 proportion correctly. This will increase productivity and cost efficiency at PT. Inalum Kuala Tanjung.

Conclusion

In order to improve the performance of aluminum production, it is necessary to carry out tighter supervision of ALF3 levels in the bath. Accurate monitoring and regulation can reduce the risk of temperature fluctuations and ensure that the reaction in reduction pots takes place optimally. Thus, PT. Inalum Kuala Tanjung can achieve better product quality and higher efficiency, supporting the company's goal to become one of the main players in the global aluminum industry.
