Determination of the Cast Iron Carbon Equivalent (CE) Value in the Anode Division Process at PT Inalum Kuala Tanjung Batu Bara Rodding Plant

In the industrial world, especially in the field of metal smelting, material quality is largely determined by the right chemical composition. One important parameter that affects the quality of cast iron is the carbon equivalent (CE) value. This value functions as an indicator that measures the amount of carbon in cast iron, which in turn affects the material resistance when through the process of handling rodding between the rod and anode that has been roasted. According to applicable standards, the ideal value of Carbon Equivalen (CE) ranges from 4.7 to 4.9. If this value is below that range, the cast iron will be more vulnerable to cracks, which can cause the release of anode baked from rod anode, thus affecting the efficiency of its use.

The importance of maintaining the right carbon equivalent (CE) value cannot be overstated. Inappropriate processing can cause final products that are not in accordance with specifications. In the context of PT Inalum, failure to maintain this value can result in financial losses and decreased operational efficiency. Therefore, strict quality controls need to be done during the production process. The quality of cast iron produced directly affects the efficiency of the rodding process, making it crucial to determine the carbon equivalent (CE) value accurately.

Analysis of Carbon Equivalen Value

The carbon equivalent (CE) value is the result of calculations involving various other elements besides carbon, such as silicon, manganese, and phosphorus. Each of these elements contributes to the mechanical and physical properties of cast iron. Imbalance in composition can be fatal. For example, if the carbon content is too low, then the strength and endurance of cast iron in the face of mechanical stress is reduced, thus triggering the risk of cracks. The presence of other elements in cast iron can either enhance or detract from its quality, making it essential to monitor their levels carefully.

The carbon equivalent (CE) value obtained for cast iron of 3.52 and 4.73 indicates that although one value, which is 4.73, meets the specified standards, the value of 3.52 is far below the minimum limit required. This condition raises concerns about the quality of cast iron produced, especially in the context of the rodding handling process. The discrepancy in carbon equivalent (CE) values highlights the need for quality control measures to be implemented during the production process.

Quality Improvement Strategy

To ensure that the carbon equivalent (CE) value is always within the desired limit, several strategies can be applied:

Control of raw materials: Ensuring that the raw materials used have carbon content and other elements as needed. The quality of raw materials directly affects the quality of the final product, making it essential to source materials from reputable suppliers.
Routine testing: Perform periodic testing of cast iron produced to evaluate the consistency of carbon equivalent (CE). Regular testing helps to identify any deviations from the desired carbon equivalent (CE) value, allowing for corrective action to be taken.
Operator Training: Providing training to operators and technicians regarding the importance of chemical composition control and its impact on product quality. Well-trained operators and technicians are better equipped to identify and address any quality control issues that may arise during the production process.
Implementation of quality control measures: Establishing a quality control system that includes regular monitoring of raw materials, production processes, and final products. A robust quality control system helps to ensure that the carbon equivalent (CE) value remains within the desired limit, thereby improving the overall quality of the cast iron produced.

By applying the steps above, PT Inalum can improve the quality of the cast iron produced and ensure the value of Carbon Equivalen (CE) remains within the established standards, thereby increasing the competitiveness of the company in the market. The implementation of quality control measures is crucial to ensuring the quality of cast iron produced, which in turn affects the efficiency of the rodding process.
