The term peeling refers to the removal of the surface layer (called chips) of the round bars through a cold working process.
The operation takes place mechanically, using machines equipped with cutting tools, which remove a surface layer of material, rotating and advancing on the circumference of the profile.
Peeling the external part of a round profile allows you to calibrate the diameter and to remove the area, which is most affected by the surface defects, that can arise during the hot manufacturing phases of the steel (oxidation, surface decarburization, porosity, surface discontinuities, etc.).
The peeled bars then undergo a rolling and straightening process, which further improve the straightness and roughness of the product, thus obtaining a smooth and shiny product.
The advantage of the peeling process is that it leaves the physical and mechanical properties of the used hot rolled product unaltered.
The peeling processes are suitable on all types of steel.
