The diagram illustrates the way in which wire is produced for industrial and commercial purposes.
Looking at the illustration, it is immediately evident that wire production is a man-made linear process that is carried out using a combination of machinery and high temperatures, rather than by hand.
Additionally, the process consists of nine main stages, beginning with the extraction of raw materials and culminating in the production of finished wire products.
In the first step, iron ore and coking coal are fed into a blast furnace, where they are heated to approximately 1300°C in order to produce molten iron. Following this, the liquid metal is transferred to an arc furnace, in which it is heated further to around 1800°C. Once this stage has been completed, lime is added during the combining process so that impurities can be removed, resulting in refined liquid metal.
At the next stage, the molten metal is poured into moulds to form solid metal bars. Afterwards, these bars undergo pressing and shaping, before being cooled at about 500°C. Having been cooled, the material is processed into pipes or wire, and the process ends when the finished products are ready for industrial use, thereby completing the production cycle.
