Rolling is the process by which steel strips are shaped and formed. To achieve this, large steel billets or slabs are passed through a series of rolling mills. These mills apply pressure and force to the metal, transforming it into thin, flat strips. The rolling mills are equipped with rollers that gradually reduce the thickness of the steel strip at each stage.
The process begins with heating the steel billet to a high temperature, making it more malleable. The hot billet is then fed into the first rolling mill, where it passes through a set of rollers that progressively decrease the strip's thickness. Afterward, the strip is cooled and transferred to the next rolling mill, where the process is repeated.
Each rolling mill has a specific roll configuration designed to give the steel strip the desired shape and dimensions. This can include flat rolls, which evenly compress the strip to reduce thickness, or shaped rolls, which create specific cross-sectional profiles like round, square, or rectangular shapes.
Once the desired shape is achieved, the steel strip may undergo additional processing to enhance its mechanical properties. Annealing or tempering can be employed, involving heating and cooling the strip to alter its microstructure and improve strength, ductility, and hardness.
Aside from rolling, steel strips can also be formed using cold forming or stamping techniques. Cold forming shapes the steel strip at room temperature using dies or molds, commonly used for creating complex shapes and precise dimensions. On the other hand, stamping involves cutting or shaping the steel strip using a press with a die specifically designed for the desired shape.
In summary, the shaping and forming of steel strips combine heating, rolling, and other forming techniques to achieve the desired shape, dimensions, and mechanical properties. These processes play a crucial role in the manufacturing of various steel products, including automotive parts, construction materials, and household appliances.

Each rolling mill has a specific roll configuration designed to impart the desired shape and dimensions to the steel strip. This can include flat rolls, which compress the strip to reduce thickness evenly, or shaped rolls, which create specific cross-sectional profiles such as round, square, or rectangular shapes.
Once the desired shape is achieved, the steel strip may undergo further processing such as annealing or tempering to enhance its mechanical properties. These processes involve heating and cooling the strip to alter its microstructure and improve its strength, ductility, and hardness.
In addition to rolling, steel strips can also be formed through other techniques such as cold forming or stamping.
