Frequently Asked Questions
Metal rolling is a manufacturing process that involves passing metal through one or more pairs of rolls to reduce its thickness, even it out, and achieve desired mechanical properties. This process is essential for shaping metal into various forms and sizes.
In metal rolling, a piece of metal is passed through two rolls that rotate in opposite directions. The gap between the rolls is smaller than the thickness of the metal, causing it to deform and become thinner as it passes through. The process can be adjusted to produce the desired thickness and shape of metal.
The two main types of metal rolling are hot rolling and cold rolling. Hot rolling is performed above the metal's recrystallization temperature, making it easier to shape. Cold rolling is done below the recrystallization temperature, resulting in a smoother surface finish and increased strength.
Metal rolling produces a wide range of products, including steel beams for construction, automotive panels, railway tracks, ship hulls, pipelines, sheet metal for appliances, and aluminium foil for packaging.
