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 stone properties of the ingredients. The purpose of sinter are to be used converting iron into steel.
Sintering: A Step Between Mining Iron Ore and …
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.

What Is Iron Ore Sintering? (with pictures)
02.04.2020 · 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.
Ore Sintering - an overview | ScienceDirect Topics
Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation. As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material ...

Iron Ore Sinter - an overview | ScienceDirect Topics
Iron ore sinter /pellets are redirected from the wall of the blast furnace to the center using the bell-less top charging equipment. The top gas utilization (TGU) improves from 47.5 to 49.0% (an increase of 1.5%) due to better contact of the ferrous burden with the CO-rich gas in the furnace center. As this was an unanticipated result and no other process changes were made, what is the ...
