In order to study in depth the differences in basic characteristics between iron ore fines commonly used by a steel company, and guide the sintering performance plant to choose the best ore allocation method, experimental studies on the basic characteristics of seven iron ore powders of three sizes were carried out using micro-sintering Coarsening Condition of Iron Ore Fines. As the main iron ore fines, ore A from Brazil and ore B from Australia were applied in Jingtang sintering process. In 2009, for the measured particle size of ore A, proportion of < 0.15 mm particles was 36%, proportion of > 5 mm particles was 26%, and the average particle size was 3.60 mm.Particle Size Matching Mechanism of Blending Ore and Solid

The <15 mm under size portion (~15 % of coke production) is screened out in the coke oven screening station, and then crushed to <5 mm as the fuel for the iron ore sintering process. The combustion heat from coke breeze provides the necessary energy for partial melting of the iron ore ultra-fines and fluxes to generate the bonding melt.So, the sintering process main objectives are to increase the size of ore additives to a level acceptable to the blast furnace for improving permeability of burden inside the BF; to form a strong agglomerate with high bulk reducibility; to remove volatile matter like CO 2 from carbonates, H 2 O from hydroxides, and sulfur from sulfide type of Sintering: Most Efficient Technologies for Greenhouse

The Relationship Between Mining and Sintering Thermo

The Relationship Between Mining and Sintering. Sinter is the primary feed material for making iron in a blast furnace, and we have previously written about sintering and how it is a step between mining ore and steelmaking. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through theThe present work proposes a novel process to sinter porous iron ore (porosity ~23–24%) with enhanced productivity and quality. The iron ore is pre-processed in the presence of calcined lime for the temporary closure of pores, which further prevents water absorption during the granulation process in drum in the presence of water.
