What Is Cold Working or Work Hardening?كسارة الحجر

13/11/· Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed. Examples of coldrolled products include steel sheets, strips, bars, and rods.

Difference between Hot Working and Cold Working

17/05/· The term "cold rolling" can be misleading. The material may start out quite cold, even as low as 32 F (0 C), but when it comes out of the cold mill, it will be far too hot to touch. This is not because heat has been applied by flame or conduction, but simply because of the massive amount of working done in the rolling process.
