Ring forging forging process is composed of several different processes, namely blanking, heating, forming, cooling after forging, pickling and heat treatment after forging. The principle and purpose of each procedure are different, forging process if the process is not the same can lead to a series of defects, if the raw materials in the presence of shrinkage pipe residue, subcutaneous foaming, serious carbide segregation, coarse non-metallic inclusions and other defects, in the forging if not adopted a certain measure, easy to make forging products inside cracks, affect the use. If the raw materials of dendritic crystals, serious loose, non-metallic inclusions, white spots, oxide film, segregation and dissimilar metal mixed with the defects, easy to cause the performance of the forging. If the surface cracks of the raw materials such as surface crack, folding, coarse crystal ring etc, shorten the service life of the products.
Forging processing is a method of processing metal, the greatest advantage of this method is that while forging can increase the properties of the metal itself, because in the process of forging will be the metal billet inside the fault and the gap to clear away, in fact, in the process of forging to increase the metal interior metal particles in the degree of bonding, so that the metal in the forging time to clear out the excess impurities.
Under the modern technical level, any kind of metal material can be made into forgings or parts by casting, but it is difficult to be different. Today, forging precision is increasing, and can reach even exceeding the usual precision level of machining.
