The diagram given illustrates the way in which wire is made for construction purpose.
looking at the illustration, it is immediately evident that wire is a manmade linear process that requires various machinery and equipment. Additionally, there are 9 stages involved in that process, beginning with coking coal and iron ore and culminating with cooling.
in the first step, the coking coal and the raw iron ore melt at 1300oC in the blast furnace to produce a semi-refined iron. Then they are transferred to an arc furnace to heat to 1800oc. It will make the iron more pure and reduce impurities. Once this has been completed the molten iron is removed to the furnace to keep the temperature at 1800oc. This step will help the molten iron remove the toxic gas that affects the quality of iron.
In the fifth stage, the liquid metal is contained in a vat to assist in pouring it into the mold. After the metal is poured into the mold to form a stick, this iron ingot is pressed and shaped in a shaping machine to create a long rod. Then it is heated at 150oc to enhance flexibility and strength. The liquid metal pipes are ready to cool. resulting in the finished wire product.
