【Abstract】 In different coefficient of thermal conductivity, two kinds of finite element model were used to simulate and solve for the annealing process. The results show that gaps and tension of degrease in sheet steel to coil can lead to biggish thermal stress. In addition, gaps in coiled sheet steel make more influence on bonding.更多还原
