Abstract
In a bending type mechanical descaling method, streak-like scales remain, which cause a die seizure in the subsequent drawing process. In the present invention, there is provided a quite new mechanical descaling technique capable of eliminating such streak-like scales. The new mechanical descaling method includes the step of passing a metal wire through a torsion generating portion for forcibly turning the metal wire around the axial center thereof while running the metal wire, thereby removing scales due to a difference in toughness between the metal wire and scales.
