Rolling Process: Definition, Working Principle

Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.

How Tea is Produced? Tea Processing and Production Steps

During the process, tea manufacturers shake the leaves in a bamboo basket or using machinery to kneed and slightly tear the. 2. Rolling-shaping During this stage, tea leaves are shaped to decent tea leaf shapes. Re-rolling lightly breaks the cell structure and instigate enzymes that promote the oxidation process.

Rolling

Rolling, in technology, the principal method of forming molten metals, glass, or other substances into shapes that are small in cross-section in comparison with their length, such as bars, sheets, rods, rails, girders, and wires. Rolling is the most widely used method of shaping metals and is particularly important in the manufacture of steel for use in construction and other industries.

Thread Rolling: What Is It? How Does It Work? Process, Types

Rolling: As mentioned earlier, thread rolling is an external threading process that shapes the stock by passing it through roller dies. The roller dies have external thread-like rollers which contact and deform the surface of the stock. Thread rolling is generally faster than thread cutting since the shaping process only requires few passes.
