摘要

The present invention relates to a molting agent for molten iron; The purpose of the present invention is to provide a molten metal dephosphorization agent having a more economical and higher dephosphorization efficiency by using a bag filter dry dust generated on the blast furnace.;The present invention for achieving the above object is a blast furnace filter dust containing 60-70% by weight of the total iron (Total, Fe) and 24-30% oxygen content: 55-70% by weight as the main component Here, it relates to a molten iron dephosphorizing agent composed of 5 to 10% by weight of quicklime (CaO): 25 to 35% by weight and a fluorite (CaF ₂ ) of at least 80% purity added as a solvent. It is to the technical point.
