    Defects in forgings when heated

    1. Beryllium oxide: beryllium oxide not only loses a lot of steel, but also reduces the surface quality of the forgings and the service life of the forging die. If pressed into the metal, the forgings will be scrapped. Failure to remove beryllium oxide will affect the turning process. 2. Decarbur...

    What is forging oxidation? How to prevent oxidation?

    When the forgings are heated, the residence time is too long at high temperature, the oxygen in the furnace and the oxygen in the water vapor combine with the iron atoms of the forgings and the phenomenon of oxidation is called oxidation. Fusible formed by iron oxide adhesion on the surface of th...

  • What is the difference between hot forging and cold forging?

    What is the difference between hot forging and cold forging?

    Hot forging is the forging of metal above the temperature of recrystallization. Increasing the temperature can improve the plasticity of the metal, is conducive to improving the internal quality of the workpiece, so that it is not easy to crack. High temperature can also reduce the metal deformat...
