Common Desulphurizers during Hot Metal Pretreatment and Application of Magnesium-based Desulphurizer in Baotou Steel Co.

WANG Hong~1,ZHANG Huai-jun~2(1.Design & Research Institute of Baotou Steel(Group) Co.,Baotou 014010,Nei Monggol,China;2.Steel-making Plant of Baotou Steel(Group) Co.,Baotou 014010,Nei Monggol,China)  
The article introduces desulphurizing technology and characteristics of common hot-metal desulphurizers such as calcium carbide-based,soda powder-based,lime based and magnesium-based ones,mainly states technology of magnesium-based desulphurizer and its application in Steel-making Plant of Baotou Steel Co..The Steel-making Plant adopts injecting combination of magnesium and lime in desulphurizing technology.Under the conditions of consumptions of Mg and lime respectively as 0.40 kg/t and 1.60 kg/t,the contents of desulphur in hot metal can be reduced to between 0.012% to 0.013%.The desulphurizing rate is above 90%.
