Band 6+: The diagram below shows the process by which wire is made. Provide an overview of the information by identifying and describing the key details, and include comparisons where appropriate.

The illustration demonstrates the sequence of manufacturing wire.

Overall, there are two primary stages are employed in the process, thermal phase and mechanical phase. The process starts with combining coal and iron ore and moulds into shape, concluding with the cooling to have the final product.

Regarding the first main stages, the first two main stages aim to produce coarse pipes and liquid metal. Initially, coking coal and iron ore are being stirred together in a blast furnace, with the temperature of 1300 degree celsius. Then, the mixture goes through the pipeline into the arc furnace, with high temperature and reduced coal inside. Next, the compound goes into the dual-purpose furnace, which removes gas from the mixture and also adds lime into it.

Concerning the remaining stage, the liquid metal is being poured to the moulds machine by the vat, before shaping into pipes. The material passes through a series of tensioners and rollers that progressively thin the material into wire strands. The wire undergoes two main cooling stages, cooling down to 150 degree celsius before cooling again to stabilize the metal for the final product.
