RESEARCH AND DEVELOPMENT OF TECHNOLOGY FOR ROLLING OF HIGH-QUALITY PLATES OF NON-FERROUS METALS AND ALLOYS IN RELIEF ROLLS.
Naizabekov, Abdrakhman; Lezhnev, Sergey; Koinov, Toncho; Mazur, Igor; Panin, Evgeniy
Studies on deformation of a plate workpiece in rolls with a surface relief in the form of annular grooves forming a trapezoidal ledges and cavities alternating each other along the entire length of the barrel (the first pair with unequal ratio of the ledge to the cavity and the second pair with equal ratio of the ledge to the cavity) have been carried out. Computer simulation of the rolling process in the rolls with unequal and equal treatment of the ledge to the depression showed the advantage of the first scheme, because in this case is implemented pure shear without compression, which is beneficial to the uniformity of distribution of accumulated plastic deformation, which, in turn, affects the forming of the workpiece. Laboratory studies have confirmed the simulation results. The analysis of the intensity of shear strain proved the superiority of the first scheme and the analysis of rolling load showed the advantage of using the relief rolls instead of smooth.
