Slag Binders Formation during Iron Ore Pellets Burning
Abstract—The formation of slag binders, which ensure the strength properties of iron ore pellets during reduction, is studied. The formation of dicalcium ferrite, which is not reduced, has been found. The formation of an irreducible binder, namely, dicalcium silicate (belite) is also discovered. However, this compound is characterized by low strength properties and cannot provide high metallurgical properties of the pellets. We decided to continue the search for the binders that provide high strength properties of pellets during reduction.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
