In this work, we studied the effect of microwave treatment red mud briquettes containting more than 48% Fe on process iron reduction under various conditions heat treatment. Research samples were collected from formed during production alumina bauxite at Ural Aluminum Smelter. The chemical composition was examined by X-ray fluorescence analysis. initial and that agglomerates obtained after in m...
In the current work, fine-grained dual-phase, high-entropy ceramics (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)B2-(Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)C with different phase ratios were prepared from powders synthesized via a boro/carbothermal reduction approach, by adjusting content of B4C and C in precursor powders. Phase compositions, densification, microstructure, mechanical properties investigated correlated. Due t...
Abstract A billet is a bar made from crude steel which surface contains scales are rich in iron oxides. This study presents the carbothermal reduction of formed billets. The process included reaction oxides contents with carbon (in ratio 5:1) and annealing tubular furnace under argon atmosphere. occurred reactions discussed using thermodynamic calculations thermal analysis indicate three-stage ...
Titanium-containing carbide slag (TCS) is the product obtained by high-temperature carbothermal reduction in Titanium-bearing blast furnace (TBFS), which contains a large amount of TiC phase with excellent electrical conductivity. In this paper, conductive cement mortar was prepared TCS as an aggregate and graphite phase. The content on compressive strength resistivity investigated. results sho...
Abstract The primary process in an electrical arc furnace (EAF) during industrial steelmaking results tons of black slags which cause pollution to the environment. In this work, iron oxides generated EAF from SIDERPERU plant, Peru was reduced via carbothermal reaction. reduction slag α-Fe is demonstrated by X-ray diffraction, Mӧssbauer spectroscopy and magnetometry. However, phases with calcium...
