Wire Breaks and Surface Damage

Presenter: Horace Pops

11:30 am - 12:45 pm

Fundamentals - General (Combined Track)

This course presents a classification of wire breaks from a perspective that compares material defects to process-related problems. Rod defects will include both casting and rolling issues such as internal voids, foreign contaminants, rolled-in scale, hot cracks, and surface porosity. The effects of wiredrawing speed and lubrication will be discussed with respect to generation of fines, shaving, galling, and other surface defects.
