Sintering operation ensures that powder particles are bonded strongly and that better alloying is achieved. or otherwise the size of particles will be decreased and they will be hardened. including changes in size. and the density required of the compaction. carbon monoxide. configuration.
The principle of sintering involves the heating of iron ore fines along with flux and coke fines or coal to produce a semi-molten mass that solidifies into porous pieces of
mixed calcium iron silicates are the major mineral phases for fluxed sinter . Sintering is a fast process and it is unlikely that equilibrium will be reached during sintering.

Sintering is a heat treatment applied to a powder compact in order to impart strength and integrity. The temperature used for sintering is below the melting point of the major constituent of the Powder Metallurgy material.
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 ...
