Subsolidus Phase Equilibria of Fe-Ni-X-O (X = Mg, Al) Systems in Air
TL;DR: In this paper, the phase equilibria of Fe-Ni-X-O (X = Mg, Al) systems, including their lower-order systems, at temperatures between 1200°C and 1600°C in air in the subsolidus region, have been experimentally studied.
Journal ArticleDOI
Phase Equilibria in Ferrous Calcium Silicate Slags: Part II. Evaluation of Experimental Data and Computer Thermodynamic Models
TL;DR: In this paper, the phase equilibria of the FeO-Fe2O3-CaO-SiO2 system at controlled oxygen partial pressures in the temperature range between 1200 °C and 1350 °C are discussed, differences between various data sources are analyzed, and discrepancies are resolved.
Journal ArticleDOI
Experimental study of phase equilibria in the PbO-ZnO-“Fe2O3”-(CaO + SiO2) system in air for the lead and zinc blast furnace sinters (CaO/SiO2 weight ratio of 0.933 and PbO/(CaO + SiO2) ratios of 2.0 and 3.2)
TL;DR: In this article, phase equilibria and liquidus in the multicomponent system PbO-ZnO-CaO-SiO2-FeO-Fe2O3 in air have been conducted over the temperature range between 1323 K (1050 °C) and 1623 k (1350 °c) to characterize the phase relations of the complex slag systems encountered in lead and zinc blast furnace sinters.
Aspects of SAF smelting of ferrochrome
TL;DR: In this paper, a review of the chemical reactions occurring in the submerged arc processing of chromite ores is provided, where phase equilibria, reaction steps and mechanisms occurring as the charge progresses through the furnace are examined, and the potential influences of these factors on the process outcomes are discussed.
Journal ArticleDOI
Investigation of Freeze Linings in Copper-Containing Slag Systems: Part II. Mechanism of the Deposit Stabilization
TL;DR: In this paper, it was shown that the steady-state thickness of freeze linings is not the result of equilibrium freezing but rather represents a state of dynamic equilibrium that is critically dependent on the relative rates of crystallization, mass, and heat transfer processes, occurring close to and at the deposit interface.
