Because the cupola does not require a reducing agent, CO2 generation can be greatly reduced in comparison with the blast furnace process. Moreover, because the latent heat of the cupola off-gas can be utilized effectively in steel plants by blast furnace gas recovery equipment, the cupola was introduced in JFE Steel East Japan Works. In this report, the effects of coke diameter and oxygen concentration of blast on the reaction rates of coke combustion, coke gasification and carburization in the cupola were studied. Operation was simulated from the viewpoints of these reactions and heat transfer between coke/scrap and shaft gas. In addition, the changes in the off-gas composition, coke rate, hot metal composition, were observed in an operating small cupola under several conditions of coke diameter and oxygen concentration of blast.
