Sintering process. Sintering is the process of compacting and forming a solid mass of object by heat or pressure without melting it to the point of liquefaction [9,10]. Moreover, the sintering occurs naturally or artificially (manufacturing) processes. Sintering process is one of factors of the deactivation process .
Nov 19, 2018· However, when particles tend to the nanoscale, sintering becomes a diffusion process dominated by grain boundary and surface diffusion between particles. As such, this paper presents an approach to model sintering by tracking the diffusion between nanoparticles on a bed scale.
Nov 16, 2018· The objectives of the experiment are to study how the reduced gravity conditions influence the formation of the microstructures in the sintering process of powder materials, and to demonstrate that materials obtained through this process have better characteristics of strength and uniformity as compared to groundbased processes.
Process for manufacturing a sintered moulded part from iron materials which is porefree in individual zones or peripheral zones and is porous in the remaining zones, characterised in that a moulded part reduced to a ca. 10%vol. residual porosity according to the conventional powder compression and sintering processes is reduced, in a further processing stage by the introduction of additional materials .
the dosing subprocess of the sintering ores, as well as the simulation of the iron ores' sintering subprocess [4,11].The subsystem from fig. 2 makes the calculation of the material flow that compose the sintering charge, : the iron ore flow, limestone flow, coke flow and the return flow considering that
This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and the beneficiation. This book focuses on agglomeration, or the size enlargement process, of iron ores.
process of sintering in agglomeration of iron ore. Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slagforming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. Contact Supplier
Briquetting is the simplest agglomeration process. Fine grained iron ore is pressed into two pockets with the addition ofwater orsome other binder agent (molasses, starch, ortar pitch) to form briquettes [8]. A traditional application is the agglomeration of coal [8], other example is

Iron ore sinter is produced by lumping and sintering the iron ore concentrate, sintering ore, coal dust, and flux additives (the agglomeration process). In the iron and steel industry, iron ore sinter is used as the primary iron ore feedstock for ironmaking in blast furnaces.

As we know, the innovative process named composite agglomeration process (CAP) has a series of advantages compared to traditional sintering process (TSP). In CAP, part or all of the ironbearing dusts is made into green pellets with 515mm in diameter, while the rest of ironbearing dusts and all of the other fine ores is granulated after mixing with fuels, fluxes and return fines.
