Definitions

  • Shaped body inoculation means for introducing a silicide additive into an iron casting melt consisting of grains of said silicide embedded in a metal having a melting point lower than that of iron and shaped in a main body and peg-like projection means extending outward therefrom for positioning said body on a perforated strainer grate core with said projection in a perforation of said core.
