Metallurgical Coke – High-Carbon Fuel for Industrial Applications

Metallurgical Coke (Met Coke) is a high-carbon, low-ash solid fuel produced by heating premium-grade coking coal in the absence of air. Known for its exceptional strength, high calorific value, and consistent performance, metallurgical coke is an essential raw material used across steel, ferroalloy, foundry, chemical, and metallurgical industries.

At SparkGuys, we supply high-quality metallurgical coke with strict quality control, consistent sizing, and reliable delivery for bulk industrial consumers.

Why Choose SparkGuys Metallurgical Coke?

Metallurgical coke is produced through the carbonization of coking coal in coke ovens at temperatures between 1,100°C – 1,300°C. During the coking process, volatile matter is removed, leaving behind a dense and porous carbon structure ideal for high-temperature industrial operations.

This material acts as:
  • A fuel (providing intense heat)
  • A reducing agent (removing oxygen from ore)
  • A structural support inside furnaces due to its strength

We ensure consistent quality and reliable supply across India.

  • ✔ Stable Sizing & Grading : Accurate size segregation for different furnace requirements (Blast Furnace, Cupola, Ferroalloy units).
  • ✔ High Fixed Carbon : Guarantees better energy performance and reduced consumption.
  • ✔ Low Ash & Low Sulfur Grades : Improves furnace efficiency and minimizes impurities.
  • ✔ Bulk & Container Supply : Suitable for large industries, continuous production units, and export requirements.
  • ✔ Technical Support : We guide customers in selecting the right coke grade for their process.

Metallurgical Coke – Size Handling & Application-Based Supply

We supply high-quality Metallurgical Coke (Met Coke) in multiple calibrated size ranges to meet the specific needs of various industrial applications. Our material is carefully screened, segregated, and packed to ensure consistent quality, uniform size distribution, and optimal performance in high-temperature metallurgical operations.

Available Size Grades

  • 5–10 mm – Ideal for smaller furnace operations, sinter plants, and chemical processes that require controlled combustion and faster reactivity.
  • 10–20 mm – Commonly used in cupola furnaces, foundries, and alloy manufacturing units where uniform heat release and stable burn rate are essential.
  • 20–40 mm – Suitable for blast furnaces, metal smelters, and steel plants, offering strong mechanical strength and efficient reduction properties.
  • 40+ mm (Lumps) – Preferred by large blast furnace operations, where high strength, low ash, and consistent structure support better permeability and furnace stability.

Each size category is processed based on end-use requirements, ensuring optimum furnace efficiency, lower slag formation, and improved energy output.

Metallurgical Coke remains a critical carbon material for the iron, steel, and foundry industries, providing the high calorific value, strong carbon structure, and stable burn characteristics required for efficient metallurgical operations. By offering Met Coke in precisely graded size ranges, we ensure that every customer receives the right specification for their application—whether it’s sintering, smelting, reduction, or high-temperature furnace work.
