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, slag-forming 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.
Get uniform pellets with excellent metallurgical and physical properties. 's traveling grate pelletizing plant is the industry's leading induration technology for iron ore pellet production for a wide range of plant capacities.
In the iron ore sintering process, it is desirable to maximize the productivity and quality of sinter while minimizing the fuel consumption for any given raw material (iron ore, flux and solid fuel) quality. However, given the complexity of the sintering process and the large number of manipulated variables, it is not practical for operators to identify appropriate set …
The agglomeration process begins with the preparation of the burden mix for iron ore sintering and includes the following stages: material sizing, burden components dosing, mixing, moistening and pelletizing of the burden. Fine iron ore concentrate (<0.074 mm) and sinter ore fines (<10 mm) do not need crushing. ... is laid in a layer on the ...
Agglomeration of iron ores is the iron ore pretreatment process in which the powdery iron ore that cannot be directly fed into a blast furnace experiences high-temperature solidification by sintering process and pelletizing process or low-temperature solidification by pelletizing process and briquetting process to generate the rich ore material that meets the …
The process consists in: part of fine grained iron ore is transformed into 8–16 mm green pellets, while the rest and the coarse fine ores are mixed with fluxes, fuels and return fines, and then granulated (primary mixture); green pellets and primary mixture are blended (secondary mixture) and then fed to the sintering machine; the mixture is ...
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 the key ...
The Sintering Process of Iron Ore Fines. Sintering plants are normally associated with the production of hot metal in blast furnaces in integrated steel pants. ... Fig 2 Dwight Lloyd machine. A second layer of micro pellets is charged over the hearth layer and leveled. Then, the pallet car passes below an initializing furnace, where the ...

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).
High grade iron ore less than 10% of the total reserves. ROM iron ore with Fe less than 58 – 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1.
Intensification of the iron ore sintering process is approached with a four-way framework covering granulation improvement, waste gas recycling, fuel gas injection into the sinter bed, and reduction of stack emissions. Various metallurgical wastes are granulated to form micro pellets and are dosed along with the feed to cut down the cost.
The remaining 2% of domestic iron ore was produced for non-steel end uses. Seven open-pit iron ore mines (each with associated concentration and pelletizing plants), and three iron metallic plants—one direct-reduced iron (DRI) plant and two hot-briquetted iron (HBI) plants— operated during the year to supply steelmaking raw materials.
Iron ore pelletizing is an essential industrial process that transforms powdery iron ore into uniform, robust pellets, serving as a premium feedstock for blast furnaces and direct reduction reactors.
The sintering process is an intricate system with a protracted process flow. The steps in the manufacturing line are primarily composed of the ingredients and mixing process, the sintering operation process, and the treatment of the sintered ore [39, 40].2.2 Important parameters and characteristics of sintering process. As shown in Fig. 2, all variables affecting …
