In the iron and steel industry, iron ore sinter is used as the primary iron ore feedstock for ironmaking in blast furnaces. The sinter product mix comprises the products of YuGOK, such as non-fluxed sinter 62% Fe and fluxed sinter 50-57% Fe. The sinter is non-toxic, non-flammable and non-explosive.
H-VTM and CaO are made into a mixed ore powder sample at 6000 N pressure, with a diameter of 8 mm and CaO sample with a diameter of 15 mm. The mixed ore powder sample was placed on top of …
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify...
Iron ore processing Sinter evaluation Cluster analysis 3.1. Introduction The iron and steel industry is confronted by decreasing Fe grade and increasing impurity levels of its raw materials, as well as a stockpile of lower grade waste materials that need to …
The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size …
In this review, the sintering process is first described and analyzed to identify the key factors affecting the structure and quality of iron ore sinter. Under fixed …
The cooled sinter is crushed and screened for a final time, then the fines are recycled, and the product is sent to be charged to the blast furnaces. Generally, 2.3 Mg (2.5 tons) of raw materials, including water and fuel, are …
The sintering basic characteristics of iron ore play a key role in the process of sintering. In this study, the effects of B2O3 on the assimilation characteristics, softening temperature, fluidity of liquid phase, compressive strength of bonding phase, and microstructure of the mixed fine powder of hematite and …
Low-grade iron ores contain more impurities which need to be removed through beneficiation and sintering processes before the ores can be utilized in the blast furnaces [[2], [3], [4]]. Before sintering, iron ore fines are mixed with cokes and fluxes and granulated to form large size granules to improve bed permeability and sintering speed …

Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast ...
- 30 mm and sinter fines with a maximum grain size of 6 - 10 mm. The prices of direct shipping ores are often related to the historical Mesabi standard of 51.5 percent iron.
The iron ore fines with less than 10 mm size are usually fed to the sintering process, and only limited fraction (less than 20%) of − 150 micron size of iron ore fines …

It was observed from the feed analysis that 80% passing of the particles is of sizes below 2.5 mm, 2.4 mm, and 2.7 mm for the HSHA, LSHA, and LSLA iron ore samples, respectively. The density of all the three feed samples was determined using the Pycnometer. The particle density of the three feed samples varied from one another.
In the last two decades, the best potential available technologies for the sustainable and energy-efficient production of iron ore sinter comprise substitution with alternative fuels [22–60], modifying the properties of the solid fuel and reactant gas [61–107], implementing process control [108–126], and waste heat recovery and ...
