flux having low melting points for BOF refining using low Manganese hot metal and the BOF refining method

摘要

The present invention provides a composition for the low melting point maeyongje converter operating with low manganese chartered by weight less than 0.23 % characterized in that the component having a low melting point , but maeyongje composition is composed of MnO-FeO-SiO ₂ complex oxide , its component ratio is in the 10 to 30% by weight MnO %, SiO2 30 % by weight in the ~ 40%, FeO is about the melting point- maeyongje compositions and methods that work for 40 to 50% by weight percent of the low manganese hot metal converter operation , characterized in that consisting of a ..
