Sinter And Iron Ore

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 properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

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.

Iron Ore Sinter Iron ore sinter or simply called sinter is usually the major component of a blast furnace iron bearing burden material. Sinter normally consists of various mineral phases produced by sintering of iron ore fines with fluxes, metallurgical wastes and a solid fuel.

Lyncis LIBS iron ore online analyzer is a radiation-free technology used for process optimization in achieving cost-effective iron production.. Ironmaking is becoming more and more difficult with growing variations in the chemical composition of raw materials. This leads to lower quality of the final product and significantly increases energy and coke consumption in the production process.

02-04-2010· 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 ...

Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace. Sinter feed composition control is important because the various sinter feed materials are not perfectly characterized and their chemical makeup varies within a batch and between batches.

Iron Ore Sinter. Iron ore sinter – A bulk material for blast-furnace smelting, which is made by sintering ore, limestone, fine coke, screened sinter and blast-furnace dust on special belt sintering machines. Sinter quality is determined by the Fe content of iron ore, strength, destruction during heating and reduction in a blast furnace.

Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. During the iron ore sintering process in iron and steel manufacturing , an online analyzer can be used to determine the elemental composition of the bulk raw materials in sinter feed.

11-05-2020· Sandi Johnson Last Modified Date: August 10, 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.

Fig 1 Iron ore sinter. Types of sinter. Sinters are classified into acid sinter, self-fluxing sinter, and super fluxed sinter. Self-fluxing sinter has sufficient content of CaO (lime) in it which is required to flux its acid components (SiO2, and Al2O3).

There have been studies about the low‐temperature reduction degradation characteristics of pellets, sinter, and lump ore, 2 as well as the softening, shrinking, and melting reduction behavior of all charge materials or just part of them. 3-9 Even though some research has considered all iron‐bearing materials (sinter, iron ore pellets, and lump ore), the authors were not able to find ...

125 Iron And Steel Production. 125 Iron And Steel Production , Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel Iron oxides, coke and fluxes react with the ....

Corresponding to the changes in the availability of iron ore resources, the amount of impurities in iron ore has been slowly increasing. Some of these impurities have been found to have deleterious impacts on sinter quality and sintering performance.
