The diagram illustrates the procedures for manufacturing wire.
Overall, there are nine main stages in the process of making wire, starting with coking coal and iron ore, and ending with cooling the wire.
In the first phase, coking coal and iron ore are introduced into a blast furnace with heating to 1300 degrees for smelting before transferring to an arc furnace to heat to 1800 degrees which will make iron more pure and reduce impurities. Once this has been completed, the molten iron is put into a furnace to remain the temperature at 1800 degrees. In this step, the molten iron is removed from toxic gases that impact on the quality of iron.
In the next phase, the liquid metal is contained in a holding vat before pouring into the moulds to form a stick. This stick undergoes pressing and shaping to create a long bar in the furnace at 150 degrees. Finally, the metal pipes pass through a cooling step, resulting in the finishing wire product.
