by integrated steel plants that produce steel from iron ore.

In

this process, the iron ore is first









Sintering Process is

the technology for agglomeration

of iron ore fines into useful ‘Blast Furnace’ burden material.











• The treated iron from the sintering plant is fed in to the Blast furnace along with coke. The blast furnace basically does the function of











• The hot metal output from the Blast furnace is either directly fed in to the

alternative to the Blast furnace technique.











Smelting Reduction Technologies In

this process, the hot metal (liquid iron) is produced from iron ore in two
