Calculating Model of Fe_tO Activity in Alkali-containing BF Slag

摘要

The Fe_tO activity calculating model of alkali-containing BF slag was built according to the coexistence theory of slag structure at 1773K. The results reveal: it is correspond to reality and embody the structural characteristics of BF slag. The Fe_tO activity of slag increases obviously with the w(CaO)/w(SiO_2) increasing, decreases with the Al_2O_3 and MgO contents increasing.
