Sandi johnson last modified date 01 july 2020 . iron ore sintering is a type of powder metallurgy used to pretreat iron before using it in manufacturing applications. sintering involves heating iron powder to partially, but not completely, melt the iron particles. the exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.

Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and co 2 emissions. adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. sinter strength plays an important role in deciding pci rate in the blast furnaces.

The very fine iron ore product is obtained after the flotation process. in order to be used in the steelmaking process, it should be pelletized. at smaller percentages, it can also be blended into sinter feed and used at sintering units. the iron content of the csn mining pellet feed usually exceeds 66.

Iron sand sintering process najamariedomsel.de. optimum mean size of iron ore fines for good sintering process will vary from sinter plant to sinter plant since it is dependent on several factors but as a general rule higher mean size is better for permeability and hence helps in sintering productivity.

The demand for iron ore has increased significantly in recent years, with new iron ore sources being mined to meet this demand. as the composition of sinter blends changes with the availability and cost of iron ore, so too does interest in the impact of new ore types on

Size distribution of the sinter mix has not yet been optimized. therefore, the main purpose of this study was to optimize the particle size distribution of the iron ore in the raw material mixture in order to produce a desired sinter.

Iron ore fines are less desirable and of lower value as they need to be sintered before they can be utilised, otherwise it will effectively smother the air flow in the blast furnace. the reason lump is preferred is that when it is fed into a blast furnace for steel making, its particle size allows oxygen or air to circulate around the raw ...
