This process is studied and researched in the steelmaking industry in general, and in sinter plants in particular, as well as in universities and metallurgical research centres throughout the world. As a result of this research, and the experience accumulated over many years, the sintering process is well understood.
layer charging brought about marked increases in sinter production, which led to study of the effect of different factors on the performance of the sintering machines at the NLMK with the use of two-layer and one-layer charging [1, 2]. This was the first such study for sinter plants that operate on iron-ore concentrates.

In steel manufacturing, the sintering process is the main emission source of PCDD/Fs followed by the electric arc furnace process (Zhu et al. 2016). Studies performed on iron ore sintering plants have indicated that PCDD/Fs are formed through a de novo synthesis, taking place in the sinter bed in regions where the temperature is 250–450 °C.
Process Intensification (PI) is a rapidly growing field of research aiming to improve productivity, accelerate the process with higher reaction rates innovatively, improve efficiency, safety, and reduce emissions to fulfill Environmental Social, and Governance (ESG) commitments. The PI approach is also a pathfinding tool to achieve …
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 steps of the process, that is, granulation and thermal densification. Discussion is then focused on the effect of the chemical, physical, and ...
sintering process, sinter cake will be crushed and screened after discharge from the machine. Sinter having size > 5 mm will go to the cooler and then it will go to BF. Sinter with size (<150 – 200 mm) will be fed to the sinter cooler from sinter strand. Emergency water spray system shall be there at the end of sinter strand for emergency ...
The continuous sintering process was invented more than 60 years ago by two metallurgists, Arthur S. Dwight and Richard L. Lloyd, who saw a need for automation in mineral processing. Their specific objective was to beneficiate copper ore by desulfurizing and agglomerating it for copper blast furnace smelting at the Cananea plant in Mexico.
Cleaning operations will create the highest exposures due to the manual disturbance of the dust using brushes and shovels, bobcats and suction (vacuum removal). Due to the sinter process being semi automatic there is generally minimal numbers of employees on the plant during operation and when this does occur it is for only short periods of time.
The challenge of describing the general sintering process is its complexity, since every aspect of iron ore sintering is interconnected. To predict sinter plant behaviour accurately, a universal balancing model is an option to obtain useful information about the process and the plant design.
Sintering Plant The purpose of sintering process is to prepare high-quality feedstock for the Blast furnace from Itakpe Iron ore concentrate, manganese ore, Blast furnace flue dust, mill scale and other Iron bearing materials by sintering them with the corresponding amount of limestone and dolomite with coke breeze used as solid fuel.
Download PDF. Dyna (Medellin, Colombia) Luis Verdeja. Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is studied and researched in the ...
to 5.0 million tons. With respect to the sinter plant, in January 2009, the production capacity of the existing No. 5 sinter plant was ex-panded together with the installation of a new sinter machine to cover the production amount required by the new and the new No.2 blast furnaces, and a new type sinter cooler, and an exhaust
The use of sinter influences hot metal production substantially and significantly affects an integrated steel mill's total emissions. Sintering of iron ores is an enormous energy-intensive and resources consuming process. Introducing a selective waste gas recirculation (SWGR) to the sintering process reduces the energy …

Iron ore sintering is the iron ore powder agglomeration process that changes fine iron ore powder into the lumpy iron-bearing raw material used for blast furnace ironmaking. High-temperature process and addition of alkaline flux will improve metallurgical performance of iron-bearing raw material. Besides, the sintering process …
Sinter having size > 5 mm will go to the cooler and then it will go to BF. Sinter with size < 5 mm size fines will be re-cycled in the process.
