Finite Element Simulation and Experiments of Laminated Cu Cladding Fe Sheet During Cold Rolling Bonding

Abstract

ABAQUS was used to simulate the laminated Cu cladding Fe sheet during cold rolling, combining theoretical calculations, and the orthogonal test method was adopted. Meanwhiles, the rolling stress was taken as a consideration index to investigate the cold rolling processing rate, rolling speed, friction factor (upper roller), and friction factor (lower roller) 4, the best process parameters of layered metal copper/steel cold-rolled composite are selected. The results show that the cold-rolling processing rate is 52%, the rolling speed is 75 m/min, and the roller friction factor is 0.2 is the best process parameter. At this time, the rolling stress is small, and the bonding quality is the best. Cu cladding Fe sheet of the above-mentioned production process was taken into annealing experiments, SEM and an energy spectrometer were applied to photograph the surface morphology and the element distribution. The interface thickness was calculated by the diffusion distance of Fe and Cu elements, and the interface morphology and mechanical properties were combined for judgment. The results show that the annealing temperature is [Formula: see text]C and the bonding condition is the best under the condition of 4[Formula: see text]h heat preservation.
