This steel plant with an annual production capacity of 1.3 million tonnes of steel, in addition to

Utilization of micro fines in iron and steel making process

A huge quantity of iron oxides fines (60 % of ore) are generated in mines area and in different units of steel plants. Coarser sizes of these are used in sinter plant. However in sintering, there is some restriction of using micro fines. It is possible to use in pelletization, but pelletization is a cost intensive process due to its high temperature curing.

Production of Low

The use of low-SiO 2 sinter in the Kobe No. 3 Blast Furnace has brought about the increase in overall permeability due to an increase in permeability at the lower part of the furnace, in spite of a decrease in the upper part. This increase has contributed to an appreciable increase in the ore/coke ratio and rate of pulverized coal injection.

iron processing

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze)

SINTERING AND PELLETISATION OF INDIAN IRON ORES

High grade iron ore less than 10% of the total reserves. ROM iron ore with Fe less than 58 – 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1.

Innovative Development on Agglomeration of Iron Ore Fines

sintering routes are followed for using these undersize iron ore. However, sintering has a size limitation. Excessive fineness (0.5 mm) loses its bed permeability. However, a huge quantity of ultra-fines iron oxides is generated both in the mines area and in the steel plant itself. Main source of generation of ultra-fines in mines area is
