Sinter Quality and Process of Sintering Iron Ores – IspatGuru

Nov 21, 2014 ·   Normally sinter is composed of by volume 40 % to 70 % of iron oxides, 20 % to 50 % of ferrites mostly SFCA, around 10 % of dicalcium silicates, and around 10 % of glassy phase. It can also contain sulphides (FeS), pyroxenes [(Mg,Fe)SiO3], quartz and lime in small proportion.

Iron Ore Sinter - an overview | ScienceDirect Topics

Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process.

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines 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 …
