The Novel Continuous Large Deformation Technology Integrating Conventional Rolling with Equal-Channel Angular Technology

Abstract:

A new continuous severe plastic deformation (SPD) procedure integrating conventional rolling with equal-channel angular deformation (designated CR-ECA deformation procedure) was investigated. Experimental results show that the SPD procedure has the capacity of realizing continuous SPD processing of long-size work-pieces with good surface qualities. Numerical simulations by using finite element code DEFORM-3D show that the number of roller pairs had significant influences on the the CR-ECA deformation procedure. As the number of roller pairs changed from 1 to 2, 3 and 4, the effective strain increased by 10.1 %, 10.1 % and 16.1 %; the output velocity increased by 10.8 %, 15.9 % and 14.4 %; the torque of the primary feeding roller decreased by 19.0 %, 34.7 % and 45.6 %; the total torque increased by 7.0 %, 11.8 % and 13.4 %; and the energy consumption used for making unit volume work-piece subjected to unit effective straining decreased by 12.2 %, 15.0 % and 19.4 %.
