The manufacturing process of our spheroidized annealing wire is using cold heading quality or low alloy steel wire rod as the base material through four steps as intermediate drawing, spheroidized , pickling and coating, and skinpass. Intermediate drawing is the wire rod has been rust-removed and drawn as small diameter wire through the drawing dies. Spheroidized treatment is to spheroidized the Intermediate drawn wire by spheroidizing annealing furnace.
