The picture highlights the steps involved in how wire is made. Overall, commencing with mixing cocking coal and iron ore and culminating in cooling wire.
The multi-stage process begins when cocking coal and iron ore are introduced into blast furnace heated to approximately 1300 degree celcius, where they can undergo the smelting time to reduce coal. After that, they are constantly melt around 1800 degree celcius by arc furnace, which can achieve full reduction of cocking coal before, at the same temperature, they are transferred into the secondary furnace. This can ensure that the metal can be favourably formed into the purified liquid.
In the next stage, the liquid metal is transferred to a vat, followed by being poured into moulds to form billets after. Subsequently, they experience the pressing and shaping needed in order to create long rods. This is the most important period to produce the wave because of relying on the attention to detail to avoid breaking the desired structure. Finally, they are reheated by blast furnace at 150 degree celcius before they are finished by cooling machine.
