According to the dealkalization capacity of blast furnace(BF) slag with low titanium content in an integrated iron and steel company were tested and analyzed, the effects of wCaO/wSiO2,wMgO,wAl2O3,wTiO2 and initial alkali content on dealkalization capacity of BF slag were studied.The results show that:with the increase of wCaO/wSiO2,wMgO and initial alkali content,the dealkalization capacity of BF slag decreases gradually.With the increase of wAl2O3,the dealkalization capacity of BF slag increa-ses.The dealkalization capacity increases slowly with the increase of wTiO2.wCaO/wSiO2 and wMgOshould be properly reduced in BF production,wCaO/wSiO2 and wMgOshould be kept at 1.05~1.10 and 7%~8%.wAl2O3can be appropriately increased,wTiO2can be decreased appropriately.The amount of alkali entering into the BF should be reduced,in order to reduce the degree of harmness to the BF.
