read moreThe reasons for insufficient hardness of forgings caused by improper post forging heat treatment process are: Quenching temperature is too low; Quenching heating time is too short; Tempering temperature is too high; Severe decarburization of forging surface caused by repeated heating; Unqualified chemical composition of steel, etc. Forging the reasons for the high hardness of forgings caused by im...
Defects caused by improper cooling after forging Cooling crack of forging parts: during the cooling process after forging, large thermal stress will be generated in the forging due to too fast cooling speed, or large structural stress may be caused by structural transformation. If these stresses exceed the strength limit of the forging, the forging will produce smooth and slender cooling cracks. N...
Forging is widely used in automobile manufacturing. With the progress of science and technology and the continuous improvement of workpiece accuracy requirements, precision forging technology with the advantages of high efficiency, low cost, low energy consumption and high quality has been more and more widely used. According to the different deformation temperatures during metal plastic forming, ...
Forging production is one of the main processing methods to provide the blank of mechanical parts in the machinery manufacturing industry. Forging can not only obtain the shape of mechanical parts, but also improve the internal structure of metal and improve the mechanical and physical properties of metal. Generally, important mechanical parts with large stress and high requirements are mostly man...
