Abstract

PURPOSE: To suppress the sulphurizing phenomenon of molten metal and casting surface layer portions by sulphurizable material by adding one or more kinds of oxides of Ni, Fe, Cu, Co, Mn or Cr in the organic self-hardening mold containing the materials which produce sulphurizable materials such as S at the casting.
CONSTITUTION: One or more kinds of oxides of Ni, Fe, Cu, Co, Mn, or Cr are added in the mold containing the materials which produce sulphurizable materials such as S at the casting, such as the organic self-hardening mold obtainable from organic binders of acid-hardening type and sulfonic acid base hardening catalysts, generally at a rate of 1% or more, in the entire part of the mold or in the desired portions of the mold inside, or are let to exist in coat, etc.
