      When we blow oxygen in BOF Steel Making furnace the first element which get oxidized is SILICON(Si) because of its higher affinity towards oxygen i.e. higher stability of its oxide SiO2(from Ellingham diagram lower the oxide in Ellingham diagram higher its stability) DECREASING ORDER of elements basRead more

      When we blow oxygen in BOF Steel Making furnace the first element which get oxidized is SILICON(Si) because of its higher affinity towards oxygen i.e. higher stability of its oxide SiO2(from Ellingham diagram lower the oxide in Ellingham diagram higher its stability)

      DECREASING ORDER of elements based on their tendency of getting oxidized during oxygen blowing in BOF.

      Si > Mn > C > P
