STUDY ON EQUILIBRA OF VANADIUM, SILICON AND MAGANESE BETWEEN CARBON-SATURATED MOLTEN IRON AND CaO-SiO_2-CaF_2-Al_2O_3 MULTICOMPONENT SLAG AND THE STEPWISE DESILICANIZATION AND EXTRACTION OF VANADIUM FROM VANADIUM-BEARING HOT METAL-A STUDY ON RECOV
The property and the form of slag in the nickel flash smelting process were also studied. The main content includes: as the slag composition is among MgO 9%~12%, CaO 2%~8%, Fe/SiO2 1.2-1.6, (1) The change regularity of slag viscosity with MgO content;
Australia and V-Ti ore have been used in structures burden of blast furnace, this paper especially has studied the result which Al_2O_3 and TiO_2 affect the slag metallurgy properties, measured the influence about Al_2O_3 and TiO2 content to slag smelting temperature, viscosity, surface tension and liquid slag density. This paper emphasized middle-Ti slag deoxidization and synthetically utilized, provided the theory bases for CSIC blast furnace production.
The penetration has a relationship with the separate distribution of slag on the weld surface.
Then, an observation of scanning electron microscopy (SEM) and an electronic data systems (EDS) analysis of slag were performed respectively.
The separate distribution of slag on the weld pool during welding and the great constriction of arc spots were confirmed by TIG welding with helium shielding gas.
The relationship between slag distribution and weld penetration was studied by adding aluminum powder into flux AF305 to change the distribution of slag.
During welding, the separate distribution of slag on the weld pool results in the great constriction of arc spots, an increase in arc spot force, and an increase in Lorentz force within the arc and weld pool.
In this study, the effect of the fineness on the high temperature and sulphate resistances of concrete mortar specimens, produced with ground granulated blast-furnace slag (GBFS) replacing cement, is investigated.
Mechanisms of phosphate removal from aqueous solution by blast furnace slag and steel furnace slag
We report the adsorption of phosphate and discuss the mechanisms of phosphate removal from aqueous solution by burst furnace slag (BFS) and steel furnace slag (SFS).
A blended cement containing blast furnace slag and phosphorous slag
Blended cement containing blast furnace slag (BFS) and phosphorous slag (PS) is a new kind of cement.
Experimental trial of extraction processing of fluoride cinder
The fractionation of sulfur isotopes, namely, enrichment of the cinder with the heavy isotope 34S in the course of roasting of various sulfide ores and concentrates in neutral and oxidative atmospheres at 773-973 K was studied.
Parageorgbokiite, β-Cu5O2(SeO3)2Cl2, has been found at the second cinder cone of the Great Fissure Tolbachik Eruption, Kamchatka Peninsula, Russia.
Tiny Ti-Fe, Fe, and Cu-Au spherules, particles of quenched glass and cinder, and fragments of the Precambrian and Paleozoic rocks are spatially associated with volkhovites.
Fly ash in combination with small coal cinder adsorbs COD the best, while it takes in NH4+-N and TP the best when working with hollow brick crumbs.
