Best answer
Metal rolling is a metalworking process that involves passing metal through pairs of rolls to reduce thickness, alter the shape, or impart specific properties. Here's a simple explanation:

Rolling Mill Setup:

Metal is passed through pairs of rolls in a rolling mill, which can be vertical or horizontal.

Rolling Process:

The metal workpiece is placed between the rolls, and pressure is applied to deform and shape it.

Reduction in Thickness:

Rolling reduces the thickness of the metal as it passes through the rolls.

Types of Rolling:

Hot Rolling: Metal is rolled at elevated temperatures, making it easier to deform.

Cold Rolling: Metal is rolled at room temperature or slightly above, producing a smoother surface finish.

Shape Modification:

Rolling can be used to change the cross-sectional shape of the metal, such as converting a round billet into a flat sheet.

Rolling Mills:

Different rolling mills are used for specific applications, including flat rolling mills for sheets and plates, and profile rolling mills for shaping bars and sections.

Applications:

Widely used in the production of sheets, plates, bars, and various metal products for industries like construction, automotive, and manufacturing.

Advantages:

Efficient for mass production, providing consistent and precise results.

In simple terms, metal rolling is a process of passing metal through rolls to reduce thickness, alter shape, or achieve specific properties, commonly used in the production of sheets, plates, and bars.
