  • Kinetic Study on Desulfurization of Hot Metal Using CaO

     · The kinetics and reaction mechanisms of hot metal desulfurization using CaO and CaC 2 were studied in a well-controlled atmosphere with a lab scale high temperature furnace. The growths of CaS around CaO and CaC 2 were measured and compared at 1773 K (1500 °C). The parabolic rate constant was evaluated to be 5 10 −7 (cm s −1) on CaO particles and 2.4 10 −7 (cm s −1) on CaC 2.
