Bluing packaged with broken belt

Bluing packaged with broken: (with reason 1) Rolling steel strip material. Breakdown or strip tend to be more soft, back in the same pressure, reduction increases, nip Angle increases. The friction between steel strip and roll increased, so as to make the deformation instability. ( 2) Tension is too big, not with the strip material, and adjust accordingly. Tension is too large, will cause broken belt already, also can reduce rolling pressure, when pressure under the same, its reduction will inevitably increase. ( 3) Bad lubrication. Bad lubrication rolling, will increase the friction force of roller and strip, nip Angle increases, increase the instability of strip.
