Abstract The influence mechanism of basicity on the reduction swelling index (RSI) iron ore briquettes was investigated using SEM analysis and Factsage 7.3 thermodynamic calculations based addition pure CaO to Bayan Obo concentrate. results revealed that solid solution Ca 2+ in FeO lattice increased with briquettes, whereas diffusion channels Fe ions during process from resulted formation a gre...

In this work, the melting process and reaction behaviour of cerium ferroalloy in liquid ultra-low carbon interstitial free steel was investigated through a special designed hot crucible experiment using standard metallographic techniques including SEM, EDS, XRF, XRD combination with thermodynamic software FactSage 7.2. The evolution mechanism cerium-containing phases during proposed. stretched ...

The reduction process during the electrochemical production of titanium via electrolysis molten TiO 2 –SiO –Al O 3 –MgO–CaO slags has been investigated. A laboratory scale, electrolytic cell was designed to study effect concentration at ultra-high temperatures. Galvanostatic and potentiostatic experiments were performed results consistent with thermodynamic predictions using FactSage. We demons...

In some applications, deep desulfurization and deoxidation of steels without the use aluminum are required, using Si as a deoxidant instead, with double-saturated slags in CaO-SiO2-CaF2-MgO system. This work studied nonmetallic inclusion evolution for system an induction furnace compared results FactSage kinetic simulations. Steel samples were taken from steel melt analyzed ICP-MS combustion an...

Abstract We investigated the phase relations of SiO 2 -MgO-TiO system in air at 1500°C using high-temperature isothermal equilibration/quenching technique, followed by x-ray diffraction measurements and direct analysis scanning electron microscopy coupled with energy dispersive spectrometry. One single liquid domain, five two-phase domains (liquid-TiO , liquid-cristobalite, liquid-MgO·SiO liqui...

Inductively-coupled thermal plasma processes were used to produce nanosized Li2S. Prior the syntheses, feasibility of forming Li2S was first evaluated using FactSage by considering phase diagrams sulfur and different lithium precursors in reducing atmospheres; Li2O, LiOH·H2O, Li2CO3 Li2SO4·H2O all showed promises producing nanoparticles, as confirmed experiments. Argon hydrogen mixtures gases, ...

In order to achieve the purpose of high-efficiency dephosphorization by single-slag method during combined blown converter steelmaking process, CaO-SiO2-FetO-MgO-MnO-P2O5 slag system was taken as research object, and slag-forming route studied. The effects compositions on liquidus contour map phosphorus distribution ratios (recorded Lp) were calculated thermodynamics software FactSage, then the...

Waelz slag is an iron-containing waste generated during electric arc furnace (EAF) dust processing in a rotary kiln named the process. This study focuses on reduction smelting of to produce iron-based alloy. The thermodynamic simulation using FactSage 8.0 software was carried out predict temperatures metal and obtained as well their compositions. Based results, experiments were performed labora...

The syngas generated during gasification process is used for industrial heat, power generation and chemical feedstock production. Gas composition, H2/CO CO/CO2 ratios are the deciding factors producer gas end-use. In present work, rice husk air simulation carried out by non-stoichiometric equilibrium model using Gibbs free energy minimization FactSage 6.3 software. Influence of reactions effect...

HIsarna reactor is characterized by a high raw materials versatility and therefore attractive for processing secondary iron sources. Among the that can be recycled through HIsarna, zinc-bearing material has drawn special attention. Based on plant data, once dust-containing Zinc was injected into main reactor, final collected dust with zinc content of 16% achieved which opened up possibilities h...
