Abstract
A process for treating molten cast iron with pure magnesium wherein a granular mixture of magnesium granules admixed with granules of refractory material is flooded with molten iron. By employing granular refractory material of controlled size in the granular mixture, the rate of absorption of magnesium into the iron melt may be effectively controlled so as to optimize magnesium introduction at minimal costs.
