Numerical simulation was made of molybdenum plate rolling process with sinusoidal profile rolls, and the rolling process parameters were optimized by orthogonal tests. Three-dimensional entity models of both the roll and molybdenum plate were created,and the target function of optimization tests was estab- lished i. e. destruction degree of molybdenum plate. The results from orthogonal simulation rolling tests show that the optimal rolling program for producing 4 mm thick molybdenum plate is as follows.break- down rolling heating temperature of 1 200℃ with deformation degree of 37.5%,heating temperature of 1 150℃ with deformation degree of 24% for 1st rolling after 2nd firing,deformation degree of 23% for 2nd rolling after 2nd firing,heating temperature of 1 100℃ with deformation degree of 20% for 1st roiling af- ter 3rd firing,and final plate thickness of 4 mm for 2nd rolling after 3rd firing. Under the above rolling process conditions, the destruction degree of molybdenum plate may be the minimum.
