Blast Furnace Coke

Blast furnace coke is a premium grade of metallurgical coke produced from select coking coals through carbonization at high temperatures in coke ovens. It is recognized for its high carbon content, low ash and sulfur levels, and exceptional mechanical strength. In the blast furnace, coke plays a vital role by providing the heat required for smelting iron ore, acting as a reducing agent to remove oxygen from the ore, and maintaining the permeability of the furnace burden so that gases can circulate efficiently. Its strong and porous structure ensures stable furnace operation, efficient gas flow, and consistent production of high-quality molten iron. Because of these unique properties, blast furnace coke remains an indispensable material in integrated steelmaking worldwide.
