Definition of rolling mill

The phrase "rolling mill" originated during the Industrial Revolution in the mid-19th century, as it became necessary to mass-produce metal products like iron and steel. A rolling mill is a factory or machine that uses mechanical power to flatten and shape metal into various forms. The process of forming metal into desired shapes by mechanical means is called rolling. In a rolling mill, hot metal is pressed and squeezed between a series of rotating rollers, which roll and flatten it into flat sheets, bars, plates, or other desired shapes. The sheets and bars can then be further processed into finished products like construction materials, appliances, and automotive parts. The term "rolling mill" is derived from the action of the rollers in the mill, which roll or move the metal as it passes through the machine. The name reflects the efficiency and speed of the process, as large volumes of metal can be rolled and formed at once, making it a crucial component of modern mass production. Overall, the rolling mill is an essential part of metalworking and manufacturing industries, and its origins can be traced back to the Industrial Revolution, where advances in technology and innovation allowed for its widespread use.
