ABSTRACT:
The present invention is a process for drawing and forming a bright wire of a predetermined diameter and cross-section, from stock of a greater diameter. It includes the steps of (a) chemically removing scale from said stock; (b) applying a coating of lubricant carrier to the descaled stock; (c) applying drying air to the stock with the lubricant carrier thereon; (d) applying a lubricant to the carrier-coated stock; (e) drawing the lubricated stock through one or more pressure dies to decrease the diameter of the stock down to the desired predetermined diameter, including lubricating before each die; (f) buffing the drawn stock with a plurality of buffing wheels, said buffing wheels being applied to the drawn stock at a plurality of angles to the direction of travel of the stock to produce bright wire; and, (g) coiling the resulting bright wire into coils for subsequent use. The chemical descaling may be continuous or batch and the remainder of the process is continuous. The speed of the stock is maintained by conventional drive mechanisms to feed into the process and to coil off the process at predetermined speeds. The present invention also includes the apparatus for the process.
