The rate of nitrogen transport from molten iron to the gas phase through a CaO-Al2O3 melt was investigated and we propose a mixed rate determining equation. We found that it is important to keep the oxygen partial pressure in the gas phase high and the oxygen potential at the oxide melt/metal interface low for efficient nitrogen transport. From the derived equation, we also considered that nitrogen transports from the oxide melt to the gas phase even at a high nitrogen partial pressure in the gas phase.
