Q: How are steel billets manufactured?: Steel billets, which are essential raw materials for steel products like bars, rods, and wire rods, are produced using a widely used method in the steel industry called continuous casting. This process entails pouring molten steel into a mold that is cooled by water, causing it to solidify into a rectangular or square shape. The molten steel typically originates from a steelmaking furnace like a basic oxygen furnace or an electric arc furnace. Before the casting begins, the mold is heated beforehand to prevent premature solidification of the molten steel. Once prepared, the molten steel is poured into the mold using a ladle or a tundish to regulate the flow and eliminate impurities. When the molten steel enters the mold, it cools rapidly due to the water-cooled mold walls. This rapid cooling results in the outer layer of the steel solidifying and forming a solid shell. The cooling process continues as the steel progresses through the mold, and water is sprayed on it to expedite solidification. Once the solidified steel reaches the end of the mold, it is cut into desired lengths using a cutting torch or a mechanical shear. These solidified steel pieces, known as billets, are then transferred to a cooling bed or a roller table to continue cooling and solidifying. After sufficient cooling, the billets undergo inspection to identify any surface defects or irregularities. Depending on quality requirements, the billets may undergo additional processing, such as heat treatment or surface conditioning, to enhance their mechanical properties and surface finish. In summary, continuous casting enables the efficient and cost-effective production of steel billets, which are crucial raw materials for various downstream steel products.
