Abstract
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. The natural silicate is a feldspar, a nepheline or nepheline-syenite. The composition is intended for use in continuous steel casting processes.
