Fatigue damage behaviors of tin in hot rolling process were investigated based on the plastic forming CAE technology, and fatigue damage distribution of tin foil during first pass of rough rolling was analyzed. Tin foil rolling process was simulated by the finite element analysis software DEFORM-3D, and the optimized experiment scheme was presented through orthogonal experiment. The results show that fatigue damage is accumulated mainly in the slab of tin during first pass of rough rolling. Reduction and rolling velocity are mainly responsible for the fatigue damage. Fatigue damage factor is increased with increasing in rolling reduction and rolling speed. The optimized technological parameters of tin foil during first pass of rough rolling are presented as follows: the reduction of 3.5 mm, roller temperature of 60℃, rolling temperature of 100℃ and rolling speed of 60 m/min. Fatigue damage is gradually increased with tin foil rolling and reaches a maximum value at 0.06 s, then no longer changes. ©, 2014, Journal Office of Special Casting and Nonferrous Alloys.
