The process of making steel billets is known as casting. It begins by melting raw materials like iron ore, coal, and limestone in a blast furnace until they become molten iron. This molten iron is then further purified in either a basic oxygen furnace or an electric arc furnace to adjust its composition and remove impurities.
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.
Steel billets are made through a process called casting. It starts with raw materials such as iron ore, coal, and limestone being melted in a blast furnace to produce molten iron. This molten iron is then further refined in a basic oxygen furnace or an electric arc furnace to adjust its composition and remove impurities.
Once the desired composition is achieved, the molten iron is poured into a continuous casting machine. This machine consists of a water-cooled copper mold that shapes the molten iron into a solid billet. As the molten iron is poured into the mold, it rapidly cools and solidifies, forming a continuous length of solid steel.
The billet is then cut to the desired length and transferred to a storage area to cool down further before further processing. The cooling process is crucial as it helps in improving the billet's internal structure and overall quality.

Overall, the production of steel billets involves melting the raw materials, refining the molten iron, casting it into a continuous mold, and subsequently cooling and processing the solid billets. This process ensures the production of high-quality steel billets that serve as crucial building blocks for various industries such as construction, automotive, and manufacturing.
Steel billets are made through a process called continuous casting, where liquid steel is poured into a water-cooled mold to form a solid rectangular shape. The mold is then gradually withdrawn, allowing the steel to solidify and form a billet.
