Once the desired composition is achieved, the molten iron is poured into a continuous casting machine. This machine contains a copper mold that is cooled by water, which shapes the molten iron into a solid billet. As the molten iron is poured into the mold, it cools rapidly and solidifies, creating a continuous length of solid steel. The billet is then cut to the desired length and moved to a storage area to cool down even more before undergoing further processing. The cooling process is vital as it helps improve the internal structure and overall quality of the billet. After cooling, the steel billets can undergo various treatments, such as heat treatment or surface conditioning, to enhance their mechanical properties and surface finish. They can also be processed further into different shapes and sizes through methods like rolling, forging, or extrusion to meet specific requirements of customers. In summary, the production of steel billets involves melting the raw materials, purifying the molten iron, casting it into a continuous mold, and subsequently cooling and processing the solid billets. This process guarantees the production of high-quality steel billets that are essential components for industries such as construction, automotive, and manufacturing.
