    • In the temperature of the CaF2 and equivalent or less than, it is done by purpose to build up the melting point of the slag and can improve the mobility. A low temperature solvent formation for the steel manufacture refining using the quenched blast furnace slag contains calcium aluminate based minimill refining slag 60~84 weight, the metal aluminum 8~16 weight%, and the fly ash 4~16 weight% and quenched blast furnace slag 4~12 weight%, and performs the followings: a process where it transports the minimill refining slag generating during the minimill steelmaking process and the minimill refining slag separately cools; a process of smashing the cooled minimill refining slag to the size less than 50mm; a process of pulverizing the crushed minimill refining slag as described above to the size less than 3mm; a process of selecting to the minimill refining slag exceeding with 3mm; and a process of removing the ferric oxide from the minimill refining slag less than 3mm selected in the screening process.
