1, the composite layer shedding: irregular defects of composite cladding layer and the substrate to leave off the formation.

2, embossing: the irregular chromatic aberration of the roll surface due to the wrinkle and broken band of the strip, which is periodically printed on the surface of the strip during the rolling process.

3, wave: the general name of various unevenness of the plate and strip due to the uneven deformation. The waves generated by plates and edges are called edge waves. The waves generated in the middle are called intermediate waves. The waves between the middle and the sides, which are neither in the middle nor on the sides, are called the two rib waves, and the smaller and generally round waves are called breaking waves.

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

5, side side bending: the longitudinal side of the plate and belt presents a non flat state bending to one side.

6, roll down: the core is seriously deformed and the roll is not round.

7, Cuoceng: strip between the layers and irregular surface dislocation caused by surface roughness.

8, tower: roll belt between layer and layer to the side moving form tower offset.

9, loosening: the loosening between the layer and the layer when the coiling and opening, when it is seriously affected by the whole volume.

10, bird's Nest: a local "V" defect on the end of the roll. The defect in the belt coiling process or after unloading, some to be produced only after a period of time.
