Improvement of Coke Strength by PVA Coating on the Surface of Coke

open access: yesTetsu-to-Hagane, 2010
Due to enlargement, stabilized and efficient operation of blast furnaces (BF), cokes with high strength have been required in BF in recent years. Recently, on the coke reactivity with carbon dioxide, it is reported that high reactive cokes can improve the reduction of iron ore in BF and reduce carbon dioxide emissions from BF.
