Definitions

  • the coal must be introduced at a location so high above the level of the molten metal accumulating in the bottom of the reaction vessel that, on the one hand, the metal reaches the molten metal bath with as little carbon as possible and, on the other hand, no carbon is introduced into the molten metal. This avoids or reduces the effort for additional fresh treatment.
  • the choice of the height of the liquid ore column is the choice of the height of the liquid ore column. According to the invention, this must be dimensioned such that the CO formed completely reacts to form CO 2 as it rises through the liquid ore column in the reaction vessel.
