IA STUDY OF SOFTENING INTERVAL FOR REDUCED IRON-ORE MATERIALS
OF DIFFERENT FRACTION IN THE TERMS OF BLAST FURNACE
(1) Zaporozhe state engineering academy
(2) OAJ «Metallurgical combine «Zaporozhstal », Zaporozhe
There are studied causes of nonuniform of composition and qualitative indicators of
iron-ore materials at their sintering on a sinter machine. There are presented the results of
research for different factions softering degree of the recovered iron-ore materials, allowing
to forecast their action in the conditions of blast furnace, with the purpose of improvement
of indicators of its work.
Keywords: blast furnace, iron-ore material, renewal, faction, softering degree
