Blast Furnace Coke
Blast Furnace Coke is a high-carbon fuel and structural material produced from the carbonization of selected coking coal at high temperatures in coke ovens. It is primarily used in blast furnaces for ironmaking, where it performs multiple essential roles including acting as a fuel, a reducing agent, and a support structure for the burden materials inside the furnace.

IndustryDuring the ironmaking process, coke reacts with oxygen to generate heat and carbon monoxide. This heat is required to melt iron ore, while carbon monoxide helps remove oxygen from the iron ore, converting it into molten iron. Because of its high strength and porous structure, blast furnace coke also maintains the permeability of the furnace, allowing gases to flow efficiently through the burden.
- High carbon content for efficient combustion
- Low ash and sulphur levels to maintain metal quality
- High CSR (Coke Strength after Reaction) for structural stability
- Controlled size distribution for better furnace permeability
