The process of forging flange generally includes the following steps: Raw material preparation: according to the design requirements, select the appropriate metal material and cut or cut to get the appropriate size of the raw material block. Preheating: The raw material block is heated to the appropriate temperature, usually using a fire or electric heating furnace to preheat, in order to improve the plasticity and forging performance of the material. Forging forming: The preheated raw material block is placed on the forging machine and processed into the desired shape by forging pressure. Forging can be divided into free forging, die forging and closed forging and other different ways, the specific method according to the shape and size of the flange. Finishing processing: After forging, the flange needs to be blanked, deburring, grinding and other finishing processing steps to improve the surface quality and dimensional accuracy. Annealing treatment: annealing treatment of the forged flange, that is, under the appropriate temperature and time conditions, make it slowly cool to eliminate the internal stress and improve the plasticity and toughness of the material. Inspection and testing: The forged flange appearance quality, dimensional accuracy, mechanical properties and other aspects of inspection and testing to ensure that the product meets the design requirements and related standards. Surface treatment: According to the need, the surface treatment of the forged flange, such as anti-corrosion coating, sandblasting, galvanized, etc., to improve its corrosion resistance and beauty. Packaging and delivery: the forged flanges that have passed the inspection are packaged, marked and packaged according to the transportation requirements, and finally delivered to the customer or stored in the warehouse.
