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.

铁矿石球团燃烧过程中形成的炉渣粘结剂

摘要研究了确保铁矿球团在还原过程中强度特性的矿渣粘结剂的形成。研究发现了未被还原的铁酸二钙的形成。此外，还发现了一种不可还原的粘结剂，即硅酸二钙（贝利特）。然而，这种化合物的特点是强度低，无法为球团提供高冶金性能。我们决定继续寻找在还原过程中能使球团具有高强度特性的粘结剂。

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.
