What are the common quality defects of aluminum rolls for sale?

What are the common quality defects of aluminum rolls for sale? To make all of our clients understand the quality of the aluminum roll they buy, we Haomei as a professional aluminum product manufacturer and supplier feel obliged to give some detailed info on this question!

  1, composite layer off: composite material cladding aluminum layer left the matrix and off the formation of irregular defects.

  2, embossing: due to strip wrinkling, broken strip and other reasons leading to irregular colour difference of the roll surface in the rolling process periodically printed on the surface of the strip colour difference phenomenon.

  3, wave: plate, strip due to uneven deformation and the formation of a variety of different uneven phenomenon of the general term. Plate, strip edge of the wave called the edge of the wave, the middle of the wave called the middle of the wave, in the middle and the edge between neither in the middle nor in the two sides of the wave called the two-rib wave, the size is smaller and usually rounded wave called broken wave.

  4, warped edge: after rolling or shearing, the edge of the strip warped.

  5, side bending: the longitudinal side of the plate, strip showing to a certain side of the bending of the non-straight state.

  Aluminium coil

  6, collapse volume: volume core serious deformation, volume shape is not round.

  7, wrong layer: strip end face layer and layer between irregular misalignment, resulting in uneven end face.

  8, tower shape: strip volume layer and layer between the layer to the side of the tampering formation tower offset.

  9, loose volume: rolled, unrolled layer and layer between the loose, serious when the wave and the whole volume.

  10, swallow's nest: with the end of the volume surface produced local "V" type defects. This defect is produced in the process of rolling or after unrolling, some to be placed after a period of time to produce.

  Through the above Haomei aluminum introduction we understand the quality of aluminum rolls related content, we only have a full understanding of the quality of aluminum rolls and understanding, in order to ensure that its products are more effective.
