Abstract:
     The production process of carbon steel and spring steel wire includes the following steps: 1. lead patenting treatment of steel wire material; 2. surface treating steel wire borax surfacing agent to form lubricating powder carrier for the stretching process; 3. performing 11-13 gates of continuous drawing of the steel wire in a turned cone pulley combination while using calcium-base lubricating powder in the first three gates and sodium-base lubricating powder in the rest gates and making the steel wire move in the speed lower than that of the cone pulley linear speed; and 4. regulating the turn height and diameter of the spring wire in an angle regulator to obtain the carbon steel and spring steel wire product. The present invention has the advantages of no need of phosphorizing the steel wire before stretching and easy electroplating of the spring steel wire.
