STUDY OF SURFACE DEFORMATION DURING ROLLING OF THE BAR CALIBERS

Abstract

Studies of defects distortion during square billets rolling in various forms of bar calibers were held in laboratory conditions. Established are qualitative and quantitative dependences between defects forming during the rolling process and the following factors: the degree of deformation, the location and spatial orientation of the defects on the initial billet. The mechanism of the influence of the shape and the size used in calibers rolling on the intensity of generation of the billet surface defects is disclosed.
