Abstract
Kinetic models of elements oxidation during vanadium extraction from hot metal by converter were established according to the theory of the metallurgical thermodynamics and reaction engineering. The results showed that silicon and titanium in hot metal were oxidized rapidly during the initial blowing stage (0 to 2min), and then vanadium began to be quickly oxidized after blowing 2 min. With temperature increasing, the oxidation rate of vanadium and carbon was transferred and carbon began to be oxidized quickly after 4.5 min blowing. In addition, the oxidation of manganese and chromium happened throughout the blowing process. It was found that the calculated values according to the kinetic models were well consistent with the practical data.
