In the molding foundry industry, carbon raisers are commonly used as an additive to improve the quality and properties of the final product. Carbon raisers are carbon-based materials that are added to molten metal to increase its carbon content. The addition of carbon raisers can improve the strength, hardness, and other mechanical properties of the final product.

Carbon raisers serve several functions in the molding foundry industry. Firstly, they increase the carbon content of the molten metal, which improves its mechanical properties. Secondly, they reduce the amount of oxygen and other impurities in the molten metal, which improves its quality. Finally, they improve the flowability and castability of the molten metal, making it easier to pour and mold.

Carbon raisers are available in different forms, including calcined petroleum coke (CPC), graphite, anthracite coal, and metallurgical coke. They have different features depending on their specific composition. Generally, carbon raisers have a high carbon content and low ash and sulfur content. They are also available in different particle sizes, which can affect their performance in different applications.

The addition of carbon raisers to molten metal has several advantages in the molding foundry industry. Firstly, it improves the mechanical properties of the final product, including its strength, hardness, and ductility. Secondly, it reduces the amount of impurities in the molten metal, which improves its quality and reduces defects in the final product. Finally, it improves the flowability and castability of the molten metal, making it easier to pour and mold.

One disadvantage of carbon raisers is that they can increase the cost of production. Additionally, excessive use of carbon raisers can lead to brittleness in the final product.

Influence of Carbon Raisers on Molding Foundry Products:
The addition of carbon raisers to molten metal has a significant influence on the properties of the final product. It improves the mechanical properties of the final product, including its strength, hardness, and ductility. Additionally, it improves the quality of the final product by reducing impurities and defects.

Carbon raisers play a crucial role in the molding foundry industry. The addition of carbon raisers to molten metal improves its mechanical properties, quality, flowability, and castability. While carbon raisers have several advantages, they can increase the cost of production and lead to brittleness if used excessively. Therefore, manufacturers must carefully balance the benefits and drawbacks when adding carbon raisers to molten metal during the production process.
