stainless steel wire mesh(High-precision and low residual stress,steel hot rolling mill machine)

1. High-precision 2. Low residual stress 3. Automatic threading

This new type of leveler line is developed for high-precision copper strip production. It uses our innovation technology with completely independent intellectual property rights. A prepositive stretch-bend-levelling unit is combined with a 23-roll leveler, in which case 4 segments of tension and 2 segments of elongation could be controlled separately.

• The shape of copper strip could be rectified effectively by reasonable distributing 2 segments of elongation. In addition, 23-roll leveler working with smaller elongation will be beneficial to eliminate residual stress and to extend roll life-span.

•  High-precision and low residual stress, the quality of copper strips rectified by this type of leveler line could meet the needs of electronic industry.Technological parameter:
