六元熔融还原渣黏度的分析
Analysis on the viscosity of six different compound smelting reduction slag
摘要
Abstract
In combination with Huimin high-phosphorus iron smelted by smelting reduction and HIsmelt ironmaking technology ,w hich have the advantages of high efficient dephosphorization ,CaO-SiO2-Al2 O3-MgO-FeO-P2 O5 slags with basicity R (mass ratio of CaO to SiO2 )ranging from 0 .8 to 1 .4 ,Al2 O3 ranging from 6 .4% to 15 .4% ,P2 O5 ranging from 0 to 3% and the content of MgO and FeO fixed as 4% and 6%respectively ,are studied .The slags are synthesized by reagent grade .The mineral composition and microstructure of the slags are studied with scanning electron microscope and the effects of changes in the composition of smelting reduction slags on its viscosity are studied by RTW-10 melt comprehensive physical properties measuring apparatus .Results show that the mineral structure of slags are mainly composed of melilite(gehlenite and akermanite) ,w hich is characterized by square and thick skeleton form .T he viscosity decreases with the increasing of the slag basicity at fixed P2 O5 or Al2 O3 mass fraction ,increases with the increasing of Al2 O3 mass fraction at fixed slag basicity or P2 O5 mass fraction ,and increases with the increasing of P2 O5 mass fraction at fixed slag basicity or Al2 O3 mass fraction .关键词
