Infographic: the Iron and Steel Manufacturing Process

Steel is made primarily in a two-step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.

Changes to Iron Production | History of Western ...

Iron and Industrial Revolution in Britain. 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.

Metal Profile: Iron Properties and Characteristics

The iron is poured into the stacks along with coke (carbon-rich coal) and limestone (calcium carbonate). Nowadays, the iron ore normally goes through a process of sintering before entering the stack. The sintering process forms pieces of ore that are 10-25mm, and these pieces are then mixed with coke and limestone.

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.

Jessica Ellis Iron ore is combined with charcoal in a blast furnace to create pig iron. The process of pig iron production involves the combination of iron ore, charcoal, and an intermediary material known as a flux inside a blast furnace.As the materials combine with intense heat, much of the iron ore melts, creating a superheated, liquid form.
