It is an advantage of the invention that on a kind of 1600mm forging roll large-scale blade roll forging die enabling design method, in roll forging process
In make roll forging part close to blade final shape, the cross-sectional width size of same position is kept not during the roll forging of three passages
Become, and thickness is reduced, and reaches final blade dimensions, and whole process so that length direction be made to increase with this roll forging technology
There is not overlap.This net finish roll forging technology not only improves stock utilization, but also improves the grain size of material, energy
Forming better metal streamline makes the performance of blade be greatly improved.
