Feb 16, 2017· ABSTRACTSintering 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). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
Agglomeration has many applications in food processing and major applications include easy flow table salt, dispersible milk powder and soup mix, instant chocolate mix, beverage powder, compacted cubes for nutritional-intervention program, health bars using expanded/puffed cereals, etc.
A sintering machine, or blast roaster, can conduct oxidizing or reducing roasts and then agglomerate the roasted calcines, or it can be used for agglomeration alone. (Agglomeration is the fusing of fine feed material into larger chunks that can be fed into a blast furnace or…

Paul Wurth's design of ignition hoods with a vertical burner arrangement enhances the sintering process. Compared to horizontal type ignition hoods, the vertical burner configuration has numerous advantages with a direct impact on plant productivity. Its compact design increases the effective sintering area and reduces specific fuel consumption.
The range of measured sintering temperatures was 780–1000 °C. For samples that did not show any agglomeration, the sintering temperatures of both laboratory ashes and PFBC ashes were similar. However, PFBC samples that showed agglomeration had a higher sintering temperature than the corresponding lab ashes.

Sintering occurs over a range of temperatures, but is accelerated as the particles approach their melting range. It takes place faster as the particle size decreases, since diffusion distances are shorter and curvature stresses are larger. For solid-state sintering, it is appropriate to think of sintering with respect to the melting temperature.

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...

AGGLOMERATION (Sintering & Pelletising) Common methods of burden preparation related to the performance improvements of iron making (blast furnaces & direct reduction process) Growth of steel industry with depleting resources of high grade ores have led to a very strong demand for both pelletising and sintering of iron ores. 5
Agglomeration, the sticking of particles to one another or to solid surfaces, is a natural phenomenon. For powders and bulk solids, agglomeration can be unwanted, resulting in uncontrolled buildup, caking, bridging, or lumping. It can also be a beneficial process, utilizing the controlled enlargement of particles to improve powder properties and obtain high-quality products.
