The more severe service conditions of ladle refractories makes necessary the use of refractories with increased resistance, particularly magnesia-type.The use of magnesia refractories also provides better desulfurization and dephosphorization of metal. Their increased effectiveness has been noted in the materials of the discussion on ladle refractories [i-4] but the shortage of periclase powder is retarding development of production of periclase (pure and with additions) refractories and compounds.The use of forsteritecontaining refractories is of interest.Wide use of them would make it possible to provide ladle treatment of steel in ladles with use of inexpensive, readily available, and ecologically clean raw material.Laboratory investigations of the interaction of refractories with slags from ladles with ladle treatment of steel have shown that the wear resistance of forsterite-containing refractories approaches that of periclase-chromite.
