  • The drawing process of waste product drawing process has a great influence on product function. Generally, large total surface reduction rate (see area reduction rate) and small pass surface reduction rate (about ≤23%) are selected to ensure the tolerance of products. About high strength spring steel wire, the exit temperature of each pass steel wire should be controlled when drawing below 150℃, to prevent the steel wire from changing cracks due to strain aging, which is the main disadvantage of steel wire obsoletion.
