The illustration demonstrates the sequence of producing wire. Overall, there are 9 stages in the process, beginning with mixing coking coal with iron ore, followed by manufacturing liquid metal, then shaping them into wire.
By the first 5 stages, it aims to make liquid metal. Firstly, the coking coal with iron ore mixture is added into the blast furnace and heated up at 1300 degrees. Then, the mixture will be transferred through a pipe to the arc furnace, the heat will increase to 1800 degrees, a little amount of coal will be taken out of the mixture, the left over will be combined with the iron. After the combining section, again they come through the pipe to the furnace, keeping the temperature, the gas will be removed from this section and lime will be added to the liquid metal. The boiled liquid will be moved to a vat waiting for the next stage.
From the vat, liquid metal will be poured into moulds, shaping and pressing the liquid into wires. The wires will be cooled down at 150 degrees, making it solid. Ultimately, the wires go through another cooling section at room temperature, rolling into rolls, now the wire is ready for consumption.
