How to eliminate the internal stress of copper strip
Internal stress refers to the stress remaining in an object when the external load is removed. It is caused by uneven volume change in the macro or micro structure of the material.
In order to eliminate the internal stress and increase the flatness of the strip, tension, bending, straightening and low temperature treatment are also necessary. The main process includes: proportioning, smelting, horizontal continuous casting - homogenization annealing, milling - cold roughing and intermediate annealing, rolling, annealing, finished rolling, degreasing, cleaning, passivation treatment, tension leveling, cryogenic treatment and inspection, slicing and packing. Reasonable control of production parameters can produce high-quality copper strip material.
A pair of objects is subjected to heat treatment (only for the properties of the steel)The two is to eliminate under natural conditions.Three is artificial by knocking, vibration and other ways to eliminate.
