Product Features
High Carbon, Low Sulfur
Low-sulfur calcined anthracite coal has a carbon content of up to 95% and a sulfur content of less than 0.25%, effectively reducing impurities in molten steel and improving metal purity and conductivity.
High High-Temperature Stability
Calcination at 2200°C forms a dense carbon crystal structure with thermal stability that can withstand temperatures exceeding 1600°C without pulverization.
High Reaction Efficiency
The high reactivity of carbon in ferroalloy smelting can increase metal recovery by 5–8%.
Product Application
Steelmaking
Low-sulfur calcined anthracite coal is used to increase carbon content in steelmaking, effectively controlling sulfur content and improving steel purity and strength. It is suitable for the production of high-quality alloy steel.
Foundry Production
It is used as a recarburizer in cast iron, improving graphite morphology and fluidity, reducing impurity formation, and achieving a denser casting structure and smoother surface.
Non-ferrous Metal Smelting
It is used as a reducing agent and thermal insulation coating in copper, aluminum, and magnesium smelting, promoting reduction reactions, reducing heat loss, and increasing metal yield.

5. What is the main working principle of low-sulfur calcined anthracite coal?
It releases fixed carbon through high-temperature calcination, providing a carbon source in steelmaking and smelting processes. Its low sulfur content also reduces impurities in the product.
6. What metallurgies is it suitable for?
It is primarily used in the smelting of steel and non-ferrous metals such as copper, aluminum, and magnesium as a recarburizer or reducing agent to optimize smelting reaction efficiency.
7. How should this coal be stored?
It should be stored in a dry, well-ventilated warehouse to prevent moisture and spontaneous combustion, and avoid mixing with flammable materials.
8. Which furnace types is it suitable for?
It is suitable for a variety of furnace types, including converters, electric arc furnaces, and open-hearth furnaces, and can be used as a recarburizer or high-temperature carbon source.
9. What are its transportation requirements?
It should be protected from moisture, compaction, and damage. Sealed vehicles are recommended to maintain consistent quality.
