Production and forging method of flange

As a pipeline system software used to complete power switch and flow monitoring components, flange has been widely used in many industries, chemical plants, metallurgical industry and hydropower projects. In the already well-known flange technology, the sealing mode is closed structure, and the rubber seals are vulcanized rubber, polytetrafluoroethylene, etc. Due to the limitation of structure type, it is applicable to high temperature, high pressure, corrosion resistance, wear resistance and other industries.

The casting process of flange includes free forging, free forging and forging. During production, different forging methods are selected according to the size and quality of steel castings.

It is easy to forge common special tools and machines at will, with good practicability and low cost. Compared with the forged wool embryo, the free forging not only fills the defects of shrinkage porosity and air outlet holes, but also makes the wool embryo have higher structural and mechanical properties.

Therefore, it has a key practical significance in the forging of flange. The free forging machines and equipment include air hammer, steam air hammer and hydraulic press, which are suitable for the production of small, medium and large-sized flanges. Free forging has high productivity, simple operation, and it is very easy to complete mechanical automation and automation technology. The specification of die forgings is high-precision, the surplus of mechanical equipment processing is small, and the connective tissue of steel castings is more effective, which greatly increases the service life of flanges.
