Factors that cause the surface of 5052 aluminum plate to be scratched

The factors that cause the surface of the 5052 aluminum plate to be scratched, the surface of the 5052 aluminum plate is attached with debris or the segregation of ingot components. When there are a large number of segregated floating objects on the surface of the 5052 aluminum plate and the 5052 aluminum plate has not undergone homogenization treatment or the homogenization treatment effect is not good, there are a certain number of hard metal particles in the 5052 aluminum plate. When the metal flows through the working belt during the extrusion process , these segregation floats or hard metal particles adhere to the surface of the working belt or cause damage to the working belt, and eventually scratch the surface of the 5052 aluminum plate;

  There are debris on the mold cavity or working belt, and the hardness of the working belt of the mold is low, so that the surface of the working belt is injured during extrusion and the profile is scratched;

  There are exposed metal or hard inclusions in the graphite strip on the discharge rail or swing bed, which will scratch the surface of the profile when it contacts with the 5052 aluminum plate;

  When the fork bar sends the profile from the discharge track to the swing bed, the 5052 aluminum plate is bruised due to the excessive speed;

  Artificially dragging the 5052 aluminum plate on the swing bed caused scratches;

  During transportation, the 5052 aluminum plates are damaged by friction or extrusion. In addition, during the transportation process, if the 5052 aluminum plate is not well packaged, it will also damage its surface.
