Sintering: A Step Between Mining Iron Ore and Steelmaking

Jun 11, 2019· World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Iron Ore Sinter an overview ScienceDirect Topics

The effect of iron ore characteristics on sintering is mainly through their impact on the granulation and densification processes. With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to their sinter plants more frequently than ever before. Hence, different scales of test

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

Mar 23, 2020· The BF is charged with metallurgical coke and iron burden materials including iron ore pellets, sinter, and lump ore. While descending in the BF the charge materials reduce. The iron‐bearing materials should reduce fast and remain in the solid form until as high a temperature as possible to ensure reaction contact with reducing gas and iron

dustrial sintering. The iron ore, flux, coke and sinter return fine were mixed for 3min and then watered to provide the sinter mix. The moisture in the mix was controlled at a suit-able level and made the mix look slightly wet. Before being charged into the sinter pot, the mix was granulated for 1 min in a 720mm long 440mm diameter drum, with
