Energy survey of the coal based sponge iron industry

Sponge iron containing 92.5% total iron could be produced with FC/Fe(T) ratio of 0.381. It is the fact that the coal consumption per ton sponge iron produced increases when the retention time decreases, since the loss of waste gas increases. The increase of exhaust losses is due to the shortened preheating zone and resulting …

Pig Iron vs. Sponge Iron

Pig iron is produced through the smelting of iron ore in a blast furnace, while sponge iron is produced through the direct reduction of iron ore in a rotary kiln. Pig iron has a higher carbon content, making it brittle and heavy, while sponge iron has a lower carbon content, making it more ductile and lightweight.
