Resumo
Coke quality is an important factor for the stable operation of the blast furnace. In the past, coke production has been mainly controlled according to cold strength. Dissections of quenched blast furnaces in recent years have emphasized the importance of the hot properties of coke. Nippon Steel has adopted coke strength after reaction with carbon dioxide or CO2 (CSR) as an important coke quality control item. This CSR cannot be fully explained by the behavior of coke in the blast furnace alone. Here are reported the study results of the behavior of coke at high temperatures in the blast furnace and the quality required of coke for use in the blast furnace.
