ABSTRACT:
A melt of magnesium-containing nodular iron partially fills an enclosure forming a space above the melt which fills with the vapor of magnesium evaporated from the melt. Magnesium is fed into the space where the magnesium vaporizes and increases the vapor pressure so as to drive magnesium into the melt and increase its magnesium content.
