Ore Sintering - an overview ScienceDirect Topics

02/04/2010  The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron and steelmaking processes. After being mixed in a rotating drum, water is then added to the mixture ...

Ironsand - Wikipedia

Ironsand is found worldwide. Although the iron mineral composition of the ironsand is mostly magnetite, the sand is usually mixed with other types of sand that washes downriver or ashore from mountainous or underwater deposits. The exact composition of the sand mixture may vary drastically even in the same geographic region. In some areas the sand may contain mostly quartz, while in others the sand may be made primarily from volcanic rock such as basalt, depending on the types of minerals along the water's p

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 ...

L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.5 Conclusions. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.

Sintering in the Powder Metallurgy Process

Transient liquid phase sintering. In a compact that contains only iron powder particles, the solid state sintering process would generate some shrinkage of the compact as the sintering necks grow. However, a common practice with ferrous PM materials is to make an addition of fine copper powder to create a transient liquid phase during sintering.

Technologies for improvement in Sintering Process –

06/08/2013  Sintering of iron ore is a metallurgical process carried out on a sintering machine. It is basically a pre-treatment process step during iron making to produce charge material called sinter for the blast furnace. It is an agglomeration process achieved through combustion. In this process air is sucked at the sinter strand through a bed of raw mixture (also called sinter mix) of iron ore fines ...
