What Is Iron Ore Sintering? (with pictures

Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical

Modification of Wet Granulation Process During Iron Ore

Sintering is the most extensively used and economic agglomeration process to prepare iron ore fines for blast furnace use. Granulation is the most critical factor controlling iron ore sintering process, as it improves sinter mix permeability. Currently, sinter plants are receiving significant proportion (up to 40%) of − 150 μm micro-fines in iron ore fines, which makes sintering difficult.

Utilization of Iron-Bearing Dusts in Iron Ore Sintering by

Iron-bearing dusts, containing valuable constituents such as Fe, CaO, MgO, C, etc., are generally utilized as raw material in iron ore sintering. However, the dusts characterized by low granulating and refractory performances always lead to negative effects on sintering indexes. As we know, the innovative process named composite agglomeration process (CAP) has a series of advantages compared
