WebFeb 18, 2015 · In the beginning of heat, the slag also contains high FeO level which is carried over from the previous heat thus aids in the removal of P. High slag basicity (CaO/SiO2 ratio) is also beneficial for the removal of P … WebMar 19, 2024 · Slag basicity (mass ratio of CaO to SiO 2 ) is an important index to ensure smooth operation and efficient separation between the metal and slag within the metallurgical industry.
Slag Basicity: What Does It Mean? SpringerLink
WebAug 5, 2024 · When the ω(MgO) and ω(Al 2 O 3) in magnesium slag were kept unchanged, the basicity was adjusted by 1.5–3.5, and ω(Fe 2 O 3) was adjusted to 10–30%, the smelting conditions were still not satisfied. Therefore, the mass fractions of ω ... Therefore, there was an optimal ratio between basicity, ω ... WebIn conclusion, the Shougang BF slag with a quaternary basicity of 1.05 has the optimum composition at the MgO/CaO weight ratio 0.15. If the MgO/CaO weight ratio is increased to 0.25, the quaternary basicity can be further increased, which will decrease the liquidus temperature and increase the desulfurization capacity. cigerci lutfi karakopru

WebThe main compounds in EAF slag are FeO, ranging from 10%–40%; CaO, from 22%–60%; SiO 2, from 6%–34%; Al 2 O 3, from 3%–14%; MgO, from 3%–13%; and some other minor elements (namely, oxidised impurities like MgO, MnO, and SO 3) [17]. WebFeb 15, 2024 · The ratio of the basic oxides and the acidic oxides of the slag is called the basicity of the blast furnace slag ("B" in short), B%= (CaO%+MgO%)/ (SiO%+Al 2 O 3 %). According to basicity, the slag can be divided into three types: Alkaline slag: B>1. Neutral slag: B=1. Acidic slag: B<1. cigerci aziz eskisehir
