The diagram given illustrates the way in with wire is made for construction purposes.
Looking at the illustration, it is immediately evident that wire production is a manmade linear process that requires various machinery and equipment. Additionally, there are nine stages involved in that process beginning with coking coal and iron ore and culminating in cooling.
In the first step, coking coal and iron ore are fed into a blast furnace heated to 1300°C in order to extract metal components from raw materials. After which, reduced coal is obtained and directed to a combining stage involving an arc furnace at a temperature of 1800°C so that impurities can be removed at high temperatures. Then, lime is added before proceeding to another combining furnace, which also operates at 1800°C, to enhance the quality and consistency of the molten mixture. Once this has been completed, the resulting liquid metal is transferred to a vat for temporary storage, before being poured into molds in preparation for shaping in the next stages.
In the fifth stage, the solidified metal from the molds is pressed and shaped in order to form it into a usable structure for final products. Next, it is transferred to a blast furnace at 150°C so that it can be reheated slightly to improve malleability. Having been reheated, the material is ready to be drawn into wire, with the purpose of producing long, thin strands of metal suitable for various applications. The process ends when, the finished wire products are cooled down to stabilize their final shape, and then packaged and sold for commercial use.
