A method for inoculating molten iron. The method comprises passing the
molten iron through a filter assembly at an approach velocity of about 1
to about 60 cm/sec. The filter assembly comprises a filter element and an
inoculation pellet in contact with the filter element. The pellet has an
inoculant dissolution rate of at least 1 mg/sec. to no more than 320
mg/sec. and comprises about 40-99.9%, by weight, carrier comprising
ferrosilicon. The pellet further comprises about 0.1-60%, by weight, at
least one inoculating agent selected from a group consisting of cerium,
strontium, zirconium, calcium, manganese, barium, bismuth, magnesium,
titanium and aluminum or from rare earths.
