Product Features
High Carbon and High Purity: Fixed carbon ≥95%, a pure and stable carbon source, effectively increasing the carbon content of the metallurgical process.
Low Sulfur and Low Ash: Sulfur content ≤0.3%, ash ≤3.5%, effectively reducing porosity, slag inclusions, and cracks, ensuring dense casting structure.
High Absorption Efficiency: The calcined anthracite carbon additive has a uniform particle size and is fully reactive, achieving an absorption rate of 95%, increasing carbon addition efficiency by 20%.
High-Temperature-Resistant Structure: The dense carbon crystal structure can withstand temperatures of 2000°C, extending service life by approximately 30%.

FAQ
Q: What is Calcinated Anthracite Carbon Additive (CAC)?
A: It is high-carbon anthracite calcined at high temperatures and used to increase the carbon content in steel and castings.
Q: What industries are CAC suitable for?
A: It is primarily used in steel smelting, casting, alloy production, and non-ferrous metal smelting.
Q: When should it be added?
A: It is recommended to add it in the later stages of molten iron melting for optimal carbon absorption.
Q: How should CAC be stored?
A: Store in a dry, ventilated place, protected from moisture and pressure. It is stable for 12 months.
Q: Can it be mixed with other carbon sources?
A: Yes, mixing with petroleum coke or graphite powder can optimize costs.
