Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace.
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.
Dioxins are identified as one of the most toxic pollutants emitted during ironmaking, specifically during the sintering process. This study applied four types of iron ores and analyzed their...
Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. Sinter strength plays an important role in deciding PCI rate in the blast furnaces.
The cheapest supply of iron ore to a steelmaker's furnace is most often the sintered iron ore fines produced from their own or others sinter plants. Sintering takes the iron ore fines and agglomerates them into strong lumps capable of being used in the furnace. It also concentrates the iron percentage being supplied to the furnace.
Iron ore sintering is a crucial stage in the whole steelmaking flow, the function of which is to process iron ores (< 8 mm) into lumpy sinter, thereby providing raw materials for ironmaking [ 1, 2, 3, 4, 5 ]. The sintering heat originates from fuel combustion, either complete combustion or incomplete combustion.

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 …
The main raw material of blast furnace iron making is sinter, and the quality of the sinter has an important impact on blast furnace iron making. A good sintering raw material structure also requires a reasonable mix of iron ore, flux, and fuel . The research on the optimization of sinter ore blending is mainly reflected in two aspects: normal-temperature …
Iron ore is typically characterized chemically, physically, and mineralogically. The effect of iron ore characteristics on sintering is mainly through their impact on the granulation and densification processes. With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to their sinter plants more frequently than ever before.
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 …
it is reported 10, 11 that the cap has the following advantages: (1) it can solve the problem of acid and alkali charge segregation of a blast furnace; (2) it can be used for recycling ultrafine fine ores, ash and other ore resources that are hard to process and utilize; and (3) it can increase productivity by more than 20% and save more than 10% …
Sinter is the primary feed material for making iron in a blast furnace. The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter quality begins with the proper selection and mixing of the raw materials.
Emission Optimized Sintering (EOS®) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:
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.
