Carbon Steel Production Process: From Ironstone to Steel Plate

The speaker, Wubi, introduces himself as an engineer from the special material and devices department and shares his experience in the production of carbon steel. He explains that the process begins with the extraction of ironstone from the earth and its combination with reductive coke. The mixture is then heated to 2000 centigrade in a blast furnace to obtain high carbon content iron. Next, the melting iron is sent to a steel workshop where carbon and other harmful elements are eliminated. The melting metal is then coated into a slab continuously. The hot steel slab is transported to a hot-rolling mill and rolled further, crimped into a coil. After cold rolling and annealing, the steel plate gets a bright surface and the desired mechanical property. The speaker concludes by describing the transformation of ironstone to melting steel liquid, coasted into a thick slab, and ultimately transformed into a shining steel plate.
