Unasylva - No. 72 - Use of charcoal in blast furnace …

Pig-iron production with charcoal in blast furnaces requires approximately the same amount as coke, 0.7 tons per ton. This corresponds to about 2 tons of dry wood per ton of iron. In view of the fact that pig iron production generally is conducted in comparatively large units, it follows that forestry operations to supply charcoal for blast furnaces must normally be of a size comparable to

1. Coke for the blast furnace Metallurgical coke is a macroporous carbon mate-rial of high strength produced by carbonization of coals of specific rank or of coal blends at temperatures up to 1400 K. About 90% of the coke produced from blends of coking coals is

How is Iron Refined from Ore? (with pictures)

29/7/2020· To create an even purer form of iron, known as pig iron, limestone must be added to the mix and the heat increased. This is done contemporarily in the silo-like structure known as a blast furnace. The calcium in limestone bonds with the silies in the ore, creating a material called slag, which floats on top of the pure liquid iron.
