EXPERIMENTAL STUDY ON REFINING ABILITY OF LF FOAMING SLAG

Experimental study on refining ability of LF foaming slag was carried.There is some conflict between slag refining ability and foaming ability.The foaming refining slag component,%: CaO 45～60, Al_2O_3 30～40,SiO_2 10～15,MgO 5～10 was obtained. The Mannesmann Index of slag is about 0.15.
