Using roll forging process to produce long shaft and plate forgings, the production efficiency is more than doubled, the investment is saved by 50%, the material utilization rate is increased by 15 ~ 20%, the energy consumption is saved by 20 ~ 30%, and there is no vibration, noise and other pollution. The production lines of automobile connecting rod, front axle, variable cross-section leaf spring, turbine blade, machine guide plowshare, forklift fork, harvester blade protector and garden spade have been built, and good economic benefits have been achieved. |
