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.
