Research of Fluoride-Free Protective Slag Used in Low C Steel
Abstract:
In order to eliminate the hazards of fluoride, the low melting point and boosting substances of Li2O, BaO, B2O3 were added into the low C peritectic steel mold powder replaced fluoride. It makes fluorine-free protection slag successfully developed. The crystalline ore phase of Fluorine-free mould slag is melilite. By adjustment crystallization ratio of melilite in slag film, the heat flow through the mold can be controlled.
