Socket flanges forging can be divided into free forging

  Socket flanges forging can be divided into free forging, upsetting, extrusion, forging, closed die forging, closed upsetting. For closed and closed upsetting, the utilization of materials is high because of no flfei. It is possible to finish the finishing of complex forgings with one process or several processes.  the force area of the forgings is reduced, and the required load is reduced. However, attention should not be paid to the restriction of billets. Therefore, we must strictly control the volume of billets, control the relative position of forging dies and measure the forgings, and try to reduce the wear of forging dies. Socket flanges in cold forging, the forging of the size changed little. It is forged under 700 centigrade, and the oxide skin is formed less, and the surface is not decarburization.

  As long as the deformation can be within the range of forming energy, the cold forging is easy to get good dimensional precision and surface finish. As long as the temperature and lubrication are controlled well. In hot forging, because the deformation energy and the deformation resistance are very small, Stainless Steel Forged Socket Flanges of complex shape can be forged. To obtain high dimensional precision forgings, it can be heated by hot forging in the temperature range of 900-1000 degrees. In addition, we should pay attention to improving the working environment of hot forging. Forging die life (2-5 1000 hot forging, temperature forging of 1-2 million, cold forging 2-5 million) compared with other temperature fields forging is shorter, but it has a large degree of freedom and low cost.
