Abstract
Converter steelmaking by using limestone instead of lime is studied in this paper. The theoretical feasibility of using limestone is analyzed. A partition model for carbon dioxide reacting with [C], [Si], [Mn] and [Fe] is established based on thermodynamic analysis. According to the mass and heat balance calculation, materials consumptions under different limestone substituting proportions are obtained. The results show that limestone can be used in converter steelmaking and the largest limestone substitution proportion is about 70%. With the increase of the limestone substitution, hot metal consumption, CO percentage and volume, CO2 output and the converter gas volume increase, while scrap consumption, CO2 percentage and the steelmaking cost decrease.
