,and cementation mechanisms,were carried out to make good use of yellow phosphorus slag as well as tackle with environment problems,safety problems,geological hazards,and high-cost issues during mining in Kaiyang... can eliminate the high residual phosphorus to improve the initial strength of backfilling body.The recommended proportions (mass ratio) are 1:1 (yellow phosphorus slag:phosphorous gypsum),1:4:10......
% titanium is in the iron concentrate after mineral processing, after smelting process the blast furnace slag containing 20%-22% TiO2 were produced[1]. The content of TiO2 in the slag is too low to separate titanium dioxide, and it is also too high to produce slag cement[2]. This slag has been already accumulated 50 million tons so far, and it is still increasing with a rate of 3 million tons per......
PRECIPITATION AND GROWTH OF PEROVSKITE PHASE IN TITANIUM BEARING BLAST FURNACE SLAG T.P. Lou1,Z.T. Sui1,L.N. Zhang1,L. Zhang1,Z.Z. Guo1 (1.School of Materials and Metallurgy, Northeastern... slags. With the increase of CaO and Fe2O3 content, VF of perovskite obviously increases. However, high basicity leads to the viscosity of slag, which results in the reduction of the average equivalent......
in poor recovery and high cost. If the molten slag could be treated after it effused from blast furnace, most of the titanium component could be concentrated in only one mineral phase which could grow... is vanadium-titanium bearing magnetite, deposited mostly around the southwestern part. About 53% titanium is in the iron concentrate after mineral processing, after smelting process the blast furnace slag......
the degree of promotion is gradually reduced. As a result of the reaction between fly ash and steel slag at high temperature, some new mineral phases and vitreous bodies with fine grindability promote... the economic efficiency and environmental benefits[1-4]. The main chemical compositions of steel slag are CaO, Fe2O3, SiO2, some MgO and the main phases are C3S, C2S and periclase, etc. Because of its high......
ON A NEW DRYER FOR SLAG OR FLY-ASH姜洪舟,李应开摘 要:<正>Granulated blastfurnace slag or fly-ash, asadmixture of slag cement or pozzolana cement, has to be driedbefore it is ground with clinker, for it contains water. Here, anew dryer for drying slag or fly-ash is recommended,which iscalled suspension dryer.关键词:......
Activity of Reducing Steel Slag of EAF郭金祥Department of Construction Engineering, National Taiwan University of Science and Technology摘 要:Reducing steel slag (RSS) was mainly acquired from five electric-arc furnace (EAF) steelmaking plants (among them, the products of two plants were carbon steel and those of other plants were stainless steel......
