THE MOLD FLUX SYSTEM OF CONTROLLED CRYSTAL PHASES AND METHOD OF CONTINUOUS CASTING OF STEEL USING THE SAME

摘要

The present invention relates to a mold flux used in a continuous casting process of a steel and, more specifically, relates to a continuous casting method using a mold flux composition which enables to efficiently control a type and number of crystalline phases in a slag film during continuous casting. The present invention relates to a mold flux which is a main subsidiary material to lubricate and control heat transfer when continuous casting of metal or of steel, and the purpose of the present invention is to provide a mold flux composition and a method thereof, which a main crystal phase exists only on a solid state slag film and efficiently blocks a formation of other secondary crystal phase.
