ABSTRACT:
Herein disclosed are dry type continuous wire drawing process and machine which can enhance the productivity by conducting in-line a wire drawing operation including the steps of flaw detection and wire repair. The wire to be drawn is mechanically descaled and is then coated with a lubricant. The wire thus coated is drawn through a drawing die. At the coating step, the wire is first coated with lime powder and then with metallic soap. Thus, the wire is drawn under dry and continuous conditions. After the drawing operation, a flaw in surface of the wire is detected. The surface flaw is located from the running speed or distance of the wire and the detecting instant. The surface flaw located is removed. The resultant wire is wound up. The surface flaw which cannot be removed is marked. An internal defect in the drawn wire is also detected with ultrasonic waves. The internally detected portion is also marked. All of the steps thus far recited and others are conducted in-line.
