Problems solved by technology

Each pass requires heating of the billet and manual replacement of the rotary forging aperture die. The production process requires a lot of manpower, which prolongs the production cycle, low production efficiency, and low product yield.
Moreover, in the process of manual operation, it is unavoidable that the heated blank is oxidized in contact with air, and the MoO formed by oxidation 3 Dissipated in the form of smoke and dust, resulting in the loss of raw materials, and the heating furnace dissipates heat to the environment, causing part of the heat loss
The production site is seriously polluted by noise and smoke and dust, and the environmental conditions are bad
