The diagram illustrates the nine‐step procedure for manufacturing wire.
Looking at the illustration, it is immediately evident that the wire-making process is a man-made linear process that requires a combination of both human labor and machinery. Additionally, there are nine main stages involved in that process beginning with coking coal and iron ore and culminating in cooled wire.
In the first step, coking coal and iron ore are introduced into a blast furnace heated to approximately 1,300 °C, where they undergo smelting. This metal, together with additional coke, is then transferred to an arc furnace operating at around 1,800 °C to achieve full reduction. The molten iron is held at this temperature in a secondary furnace to remove gases, creating purified liquid metal.
In the second phase, the liquid metal is transferred to a holding vat before being poured into moulds to make form. These forms undergo pressing and shaping to create long rods, which are reheated at 150 °C. Finally, the rods pass through a controlled cooling stage, resulting in the finished wire product.
