The basic principle of straightening steel wire:
The straightening method is used to eliminate the residual stress of steel wire. The straightening can be divided into two types: rotary straightening and roller straightening. In practical application, according to the different requirements of the products, different straightening methods are adopted, such as straightening and tempering of prestressed steel wire by rotary straightening.
Roll straightening process and the basic principle is to make the finished product after pulling with a song from the original rate of the wire through the installation in a plane (called standard straightening) or two vertical plane (called fully straightening) two rows of mutually staggered pulleys that roll a curved shape or wire, through the straightener, withstand repeated bending deformation, curvature change from big to small, the wire residual internal stress eliminated gradually, and ultimately achieve straight and achieve the purpose of straightening.
