Agglomeration of Return Fines of Sinter for Blast Furnace

and used as raw materials for the blast furnace, the perme-ability in blast furnace is not deteriorated. Thus, an agglom-eration method for return fines of sinter by a cold process should be studied. Various non-fired agglomeration methods for use of these agglomerates as a raw material for the blast furnace have been studied since the 1970s.

Reduction of Iron Ore Pellets, Sinter, and Lump Ore under

Mar 23, 2020· A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and iron‐bearing materials separately, which leads to a layered structure. The iron‐bearing materials consist of iron ore pellets, lump ore, and sinter. Sinter, lump ore, and iron ore pellets were used in
