Taking silica as an exemplary material system, we studied water-assisted densification behaviors of different crystallinities (quartz, glass, and vitreous silica). To avoid the complexity in data interpretation, …
The sintering process, as shown in Fig. 1, begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel, and return fines from the sintering process. These materials are mixed in a rotating drum, and water is added in order to reach the desired agglomeration of the raw ...
Sintering is an important process in an integrated steel plant. Researchers and steel plant engineers make relentless efforts to improve sinter machine productivity because substantial techno economic benefits are associated with it. ...

Abstract. In integrated steel mills, the sinter plant is one of the major sources of emissions to the atmosphere, whereas the emissions of waste water and solid residues from the sinter plant are ...
Sintering is a heat treatment process where loose material is subjected to high temperature and pressure in order to compact it into a solid piece. This is similar to when ice cubes adhere together in a glass of water due to the temperature difference between the ice and the water, or when you push snow together to form a compact snowball. The ...
Spark plasma sintering (SPS) is a rapid technique. Its processing parameters are usually low-voltage and low-pressure acting, using a uniaxial force and pulsed direct current (DC) to carry out high efficiency consolidation of the powder. This technique has been widely applied for various materials processing in the recent years.
The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron and steelmaking processes.

It has carried out reviews of previous literatures and data, several plant measurements and tests, experiments using process simulators (sinter-pots) and fun-damental researches.
The document discusses the sintering process at a steel plant. Key points include: 1) Sintering agglomerates iron ore fines, coke fines, limestone and dolomite and heats them below the melting point to form porous, lumpy masses for use in blast furnaces. 2) Raw materials are crushed, screened and conveyed to a mixing drum then balling drum …
sintering, the welding together of small particles of metal by applying heat below the melting point. The process may be used in steel manufacturing—to form complex shapes, to produce alloys, or to work in metals with very high melting points. In a steel-sintering plant a bed of powdered iron ore, mixed with coke or anthracite, is ignited by ...
