FIELD: metallurgy.
SUBSTANCE: according to the first version the charge contains iron ore concentrate and manganese limestone as a binding agent and flux, at that the ratio of charge components is as follows, wt %: manganese-containing limestone, 1.0-5.0; iron ore concentrate is the rest. According to the second version, the charge contains iron ore concentrate, bauxite as a modifying additive and manganese limestone as a binding agent and flux, at that the ratio of the charge components is as follows, wt %: manganese-containing limestone, 1.0-3.5; modifying additive, 1.2-1.5; iron ore concentrate is the rest.
EFFECT: increased strength of green and roasted pellets while maintaining high iron content, reduced weakening-melting range of the pellets in the blast furnace, simplified production of iron-ore pellets.
