The diagram illustrates the way in which wire is produced for commercial purposes.
Looking at the illustration, it is immediately evident that wire production is a man-made linear process that is mostly done by machinery rather than by hand. Additionally, there are nine stages involved in that process, beginning with the extraction of iron from iron ore and culminating in the production of finished wire products.
In the first step, iron ore is mixed with coking coal and heated in a blast furnace, after which liquid iron is produced so that impurities can be removed. Then, the molten metal is transferred into moulds before being allowed to cool and solidify. Once this has been completed, the solid metal is drawn into thin wires, followed by the coiling of the finished products.
At the fifth stage, the metal is drawn through a series of rollers, where it is gradually reduced in thickness and shaped into wire. Next, the wire is cooled and treated to improve its strength. Having been fully processed, the wire is ready to be coiled and packaged. The process ends when the finished products are sold for commercial use.
