Abstract
Stable pig iron production by blast furnaces is linked to the chemical, physical and metallurgical properties of raw materials, especially of the metallurgical coke. The challenge of coke production is to produce coke at low cost and high quality. In this context, this work evaluated the charcoal fines use in the coals mixture for cokemaking, reducing the use of expensive mineral coals, maintaining the required quality for the pig iron production by blast furnaces, as well proposed a route to minimize the CO2 emission from the steelmaking process. Pilot scale tests were performed with up to 20% of charcoal fines in the blend. The metallurgical coke analyzes showed the technical and commercial viability for use in up to 2% of charcoal fines in the blend of mineral coals.
