Aiming at the serious defective material and tearing in rolling process of molybdenum plate, the common roll crown, such as line roll shape, CVC roll shape and SMART Crown were analyzed comparatively in curve design of the roll shape, rolling stress and damage. And an optimal roll shape was designed to solve the above problem. The results show that optimal roll's rolling stress is 1.68 times as much as that of present roll,however, damage value resulted from optimal roll shape is the least among the four rolls shapes.
