Simultaneous reduction of chromium, iron and vanadium oxides by carbon has
been studied by conducting experiments on typical stainless steelmaking sla
gs in the temperature range of 1823 to 1923 K. In-situ gas generated due to
the reduction led to several phenomena such as foam/emulsion formation, ch
ange in foam height, size of gas bubbles and rate of gas generation. The ki
netics of vanadium oxide reduction by carbon are studied under the influenc
e of the above mentioned phenomena and the presence of chromium and iron br
ides.
