The hightemperature characteristics of iron ores play important roles in optimizing ore proportion of sintering, which are tested by using ironore fines and analytical reagent CaO as raw materials. Two calculation methods of CaO addition amount based on binary basicity (basicity method) and n(Fe2O3)/n(CaO) (mole ratio method), respectively, were employed to evaluate the liquid phase fluidity ...
The main criterion of the sintering process is the quality ... The evaluation of the properties of iron ores shows that the best ores are from Brazil, Australia and Venezuela, Table 2 [3]. They have a suitable particle size ... Sinter grade ores and concentrates are characterized as iron ore raw materials with the required granulometry ...
Sintering is a process where a mixture of ore, flux and coke is agglomerated (agglomerated) in the sinter plant to produce suitable sintered products in terms of composition, quality and ...
Sinter Plants, that produce iron ore sinter, are important units in an integrated steel plant. They face several operational challenges due to frequent changes in input raw materials, the inability to instrument key equipment in the plant, and the absence of realtime sinter quality measurement. To address these challenges, Virtual Sinter®, a digital twin of the integrated sinter plant is ...
Iron ore sintering was a hightemperature process that preparing lump burden for further ironmaking. During this process, iron ore fines, recycled ironbearing materials, fluxes, and solid fuel including coke breeze, anthracite, etc., were thoroughly mixed and then agglomerated into finished sinter under 1300 °C provided by the combustion of ...
The sintering process can be defined as a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents, and solid fuel (coke) with the objective of obtaining a product with the suitable characteristics (thermal, mechanical, physical, and chemical) to be fed to the blast furnace.
Sinter is the primary feed material for making iron in a blast furnace. 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 beltfed furnace. Sinter feed composition control is important because the various sinter feed ...
The iron and steel industry has made an important contribution to China's economic development, and sinter accounts for 7080% of the blast furnace feed charge. However, the average grade of domestic iron ore is low, and imported iron ore is easily affected by transportation and price. The intelligent ore blending model with an intelligent algorithm as the core is studied.
The sintering process converts finesized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.

Numerical Simulation Model of the Iron Ore Sintering Process Directly Describing the Agglomeration Phenomenon of Granules in the Packed Bed.
Iron ore granulation has been introduced into the steel production process since iron ore agglomeration was proven to have better metallurgical properties and more efficient iron production than natural iron ore 6,7). Both sintering and pelletizing contain iron ore granulation process, with the former preparing iron ore, fuel, flux, water and ...
The iron ore powder used in the experiments was obtained from the raw material site of a steel company in southwest China. For B 2 O 3 an analytical reagent (≥98%) was used. The chemical composition of the raw materials is reported in Table 1 and Table 2. The raw materials are mixed powder (HVTM) composed of hematite powder and vanadium ...
The typical iron ore sintering process supplies the main ferrous charge for blast furnaces in most steel mills. During sintering, first the sinter raw materials are intimately mixed and granulated to produce granules with a narrow size distribution, large mean size and sufficient strength. ... while sinter is the best candidate material for ...
2 Citations Abstract The raw materials for an integrated steelworks can be classified into four categories, which are iron ores, fluxes, fuels, and reverts. The characteristics of these raw materials strongly affect the metallurgical properties of iron ore sinter and sinter plant performance.
Sintering is a process that consists in the thermal agglomeration of a mixture of fines that comprise iron ore, recycled iron and steelmaking products, slagforming ... Iron ore sintering: Raw materials and granulation, where the concentration techniques used in the case of the iron minerals are described, as well as the current demand of iron ...
To reduce the raw material cost of the blast furnace ironmaking system and realize the collaborative optimization of the whole process from iron ore procurement to blast furnace ironmaking, He et al. [15] developed a whole system and whole process optimized sintering batching platform for blast furnace ironmaking.
During sintering process, iron ore fines, recycled ironbearing materials (dusts and slags), fluxes (dolomite, limestone, etc.), and fossil fuels, such as coke breeze and anthracite, are thoroughly mixed and agglomerated into lumplike sinter under about 1300 °C provided by the combustion of fossil fuels [10].
