The sintering operation is the most important step to produce parts with powder metallurgy techniques. Sintering is heat treatment of the produced compacted part, which created solid-state bonding between compacted pores. With these solid-state bonds, more rigid and strong structures were obtained.

May 18, 2012 Discrete element method (DEM) is used to study the factors affecting agglomeration in three-dimensional copper particle systems during solid-state sintering. A new parameter is proposed to characterize agglomeration. The effects of a series of factors are studied, including particle size, size distribution, inter-particle tangential viscosity, temperature, initial density and initial ...

Apr 01, 2020 Sintering is a physical process due to crystallite growth, and agglomeration is the cohesion of neighboring particles. Two factors may be associated with this improvement: the higher specific surface areas of oxygen carriers with low ratio of Fe 2 O 3 and higher Tamman temperature of the spinel than iron oxides.

The sintering process is particularly suited to treat ore fines, and has the advantage that it is quite practicable to add flue dust and flux to the sinter mix. Coke breeze, which is a by product of the blast-furnace coke manufacturer, is a very suitable fuel. The sintering process is not suitable for agglomerating fine

Dec 28, 2015 The origin of sintering process goes back to 1887 when F. Haberlein and T. Huntington of England invented the process of agglomeration for sintering of sulphide ores. In this process, the sintering was carried with the sintering bed being blown with air from bottom upwards. The process was also known as up-draft sintering process.

Sintering converts fine sized raw materials (e.g., iron ore, coke breeze, limestone, mill scale, and flue dusts) into an agglomerated product, sinter of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix, and then placed on a continuous, traveling grate called the sinter strand.
