| Abstract: | In this experiment, kinetics of vanadium oxidation with sodium carbonate injection treatment on liquid pig iron was investigated. The following kinetic equation is givenThe rate of vanadium oxidation increases with the increase in sodium carbonate injection. The addition of Fe2O3 or Na2SO4 in Na2CO3 increases the rate of vanadium oxidation. The effect of temperature on the rate of vanadiumoxidation is not very much. The relation k=5.692 exp {(8313)/(RT)} is given. |
