Iron Making | Boundless World History

Early iron smelting used charcoal as both the heat source and the reducing agent. By the 18th century, the availability of wood for making charcoal had limited the expansion of iron production, so England became increasingly dependent on Sweden (from the mid-17th century) and then from about 1725 on Russia for the iron required for industry.

Steel Production

The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process.
