Effect of White Mud Addition on Desulfurization Rate of Molten Steel

Abstract: Fluorspar (CaF2) is commonly used to control the fluidity of slag in ladle-refining of steel. However, because it is desirable to reduce CaF2 consumption because of its environmental impacts, the industrial waste material such as white mud (WM) was investigated as a potential substitute for fluorspar. Steel sample (Fe-0.3C-0.9Mn-0.3Si-0.03Al-0.05S, mass pct) was melted in a high-frequency induction furnace, followed by additions of ladle slag (CaO-Al2O3-SiO2-5MgO-xCaF2, CaO/Al2O3=3, x = 0 to 10 mass pct) and f… Show more

“…To decrease the melting point of lime and enhance its solubility, calcium fluoride (CaF 2 ) is commonly added [7,8]. However, this poses environmental, refractory, and health hazards [9,10], leading to strict regulations on its use [11]. Therefore, it is critical to seek alternative cosolvents to replace CaF 2 .…”
