Metallurgical COKE


Metallurgical Coke: The Backbone of Iron and Steel Production from Khorshid Alyazh

Metallurgical coke, also known as foundry coke, is a high-carbon fuel and reductant essential for iron and steel production. It is produced by heating coal in the absence of air, a process known as carbonization. Met coke plays a crucial role in blast furnaces, providing both the heat and the reducing agent necessary to convert iron ore into molten iron.

Production of Metallurgical Coke at Khorshid Alyazh

Khorshid Alyazh, a leading manufacturer of carbon products in Iran, has established a state-of-the-art facility dedicated to the production of high-quality metallurgical coke. The company utilizes a rigorous process that ensures consistent and reliable performance of its coke products.

The production process involves the following key steps:

  • Coal Selection: Khorshid Alyazh carefully selects high-quality coking coal as the starting material, ensuring optimal properties for coke production.
  • Coal Blending: Different types of coking coal are blended to achieve the desired properties for the final coke product.
  • Carbonization: The coal blend is heated in coke ovens in the absence of air. The temperature and duration of carbonization are carefully controlled to achieve the desired coke properties.
  • Coke Quenching: After carbonization, the hot coke is quenched with water to cool it and stop the carbonization process.
  • Screening and Sizing: The quenched coke is screened and sized to meet the specific requirements of different blast furnace operations.
  • Quality Control: Throughout the production process, Khorshid Alyazh employs stringent quality control measures to ensure the consistent performance of its Met coke products.

Properties and Applications of Metallurgical Coke

Khorshid Alyazh’s metallurgical coke possesses exceptional properties that make it suitable for iron and steel production, including:

  • High Carbon Content: Met coke contains a high fixed carbon content, typically above 85%, which provides the necessary reducing power in blast furnaces.
  • Low Ash Content: Low ash content is crucial to minimize slag formation and ensure efficient iron production.
  • High Strength and Abrasion Resistance: Metallurgical coke must withstand the harsh conditions inside blast furnaces, requiring high strength and abrasion resistance.
  • Uniform Size and Shape: Uniform size and shape are important for proper packing and efficient gas flow in blast furnaces.


Khorshid Alyazh’s Metallurgical Coke is a critical raw material for the iron and steel industry. Through its advanced production process and rigorous quality control, the company delivers high-performance coke products that meet the demanding requirements of blast furnace operations. The high carbon content, low ash content, high strength, and uniform size of Khorshid Alyazh’s metallurgical coke contribute to efficient iron production and the manufacturing of high-quality steel products.
