How iron is made - Forestry and Land Scotland

The iron-making process develops. Iron-making reached Britain from Europe and the Middle East around 450 BC. At this time the process only needed iron ore, charcoal and clay. Water power was used to power bellows and hammers from the 13th century, and the blast furnace was introduced in the 15th century in Belgium. Charcoal was used where there was timber in ready supply but for the areas ...

Iron processing - Iron making Britannica

A third group of iron-making techniques classed as smelting-reduction is still in its infancy. The blast furnace Basically, the blast furnace is a countercurrent heat and oxygen exchanger in which rising combustion gas loses most of its heat on the way up, leaving the furnace at a temperature of about 200° C (390° F), while descending iron oxides are wholly converted to metallic iron.

Iron processing Britannica

The applications of this cast iron were limited because of its brittleness, and in the early Iron Age only the Chinese seem to have exploited it. Elsewhere, wrought iron was the preferred material. Although the Romans built furnaces with a pit into which slag could be run off, little change in iron-making methods occurred until medieval times.

Steelmaking - Wikipedia

To make pure steel, iron and carbon are needed. On its own, iron is not very strong, but a low concentration of carbon - less than 1 percent, depending on the kind of steel, gives the steel its important properties. The carbon in steel is obtained from coal and the iron from iron ore. However, iron ore is a mixture of iron and oxygen, and other ...
