摘要 |
A composition for forming a protective layer or slag at the surface of molten steel in the mold during a continuous casting process. The composition is constituted by a mixture of a natural silicate of low melting point and an elevated contents of alkaline oxides, a basic compound, a flux and pulverulent carbon.
