The flange forging process typically includes the following steps:
1. Material Preparation for Flange Forging: Select suitable steel ingots or billets as raw materials. These raw materials are usually preheated to an appropriate temperature to improve their plasticity.
Preheating: Heat the raw materials to the forging temperature, usually above the material’s recrystallization temperature, to ensure sufficient plasticity and deformability.
Die Design and Manufacturing: Design and manufacture the forging dies according to the flange design requirements. The forging dies typically include an upper die and a lower die, as well as necessary filling and auxiliary devices.
2. Flange Forging Operation: Place the raw materials heated to the forging temperature between the forging dies, and then apply pressure for forging. This can be done using a mechanical press, a hydraulic press, or hammering.
Primary Forging: In the primary forging stage, the raw materials are deformed and initially shaped in the forging die by applying appropriate pressure.
Intermediate Annealing: After completing the primary forging, the forging is subjected to intermediate annealing to eliminate internal stress and improve its crystalline structure.
Precision Forging: In the precision forging stage, the pre-formed forgings undergo precision machining to achieve the final shape and dimensional requirements. This may require multiple forging and heating cycles.
Final Annealing: After precision forging, the forgings undergo final annealing to further improve their crystalline structure and mechanical properties and enhance their corrosion resistance.
Finishing and Cleaning: The forgings are finished and cleaned, including cutting, deburring, and grinding, to ensure surface smoothness and dimensional accuracy.
3. Quality Inspection of Flange Forgings: Forgings undergo quality inspection, including dimensional measurement, surface quality inspection, and mechanical property testing, to ensure the product meets design requirements and standards.
Surface Treatment: Surface treatments, such as painting, galvanizing, and anti-corrosion treatment, are applied as needed to improve surface hardness and corrosion resistance.
Packaging and Shipping: After all processing and inspection are completed, the forgings are packaged and then shipped to the customer, or proceed to the next production stage.The flange forging process typically includes the following steps:
