The Sintering Process of Iron Ore Fines | ispatguruMar 9, 2013 . 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 sinter with the size and strength characteristics necessary for feeding into the blast furnace. It is basically an agglomeration process.iron ore size required for sintering,How can I calculate the heat required to sinter iron ore with.Fuel requirement for sinter depends on many factors some are required basicity of sinter, Iron ore characteristics and types of metallurgical waste. Generally for high basicity if content of lime stone or dolomite is high you require more fuel to be added. Fuel content is largely dependent on Iron ore characteristics like.

The blast furnace demands sinter with high strength, a low RDI, high RI, low fines content, good average calibrated sinter size and little variation in chemical.

Fundamental study of pore formation in iron ore sinter and pellets

constituents of the raw mix, i.e. the amount of gangue components. The induration temperature and time also depend on the constituents of raw mix and the required strength. 1.2 Improvement of the quality of iron ore sinter and pellets. 1.2.1 Quality requirements.

A finite difference model of the iron ore sinter process

A model of the iron ore sintering process has been developed with the objective of being representative of the sinter pot test, the standard laboratory process in which the . The model uses the finite difference method (FDM) to solve heat and mass distributions within the sinter pot over the height and time dimensions.

Prediction of the granule size distribution of iron ore sinter feeds that .

There is considerable interest in including fine iron ore concentrate and micropellets into sinter mixes. These materials need to be accommodated in the sinter mix without adversely affecting the permeability of the sinter bed. Addition of fine concentrate and micropellets to a sinter mix will significantly affect the particle size.

For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick to larger ones, and then the appropriate amount of coke is added.
