Electrolytic Copper Brass Sheet Strip Cold Rolling Mill Lines From 16 To 3 To 1 To 0.03mm

Copper Bronze Brass Sheet Strip Cold Rolling Mills

Copper (Bronze, Brass) Strip Rolling Process:

• Hot rolling from billet down to around 15-20mm thickness,
• copper cold rolling mill will be first rough rolling mill to get around 3mm sheet,
• Intermediate rolling mill from 3mm to 1mm
• then fine rolling mill makes copper strip 0.2-0.3mm and even copper foils 0.03-0.05mm

Hot rolling and rough cold rolling steps usually 2Hi two rollers mill, reverse reduce thickness.

Copper strip Reversible Cold rolling Mill can be 4-Hi or 6-Hi to realize rough rolling, fine rolling and foil rolling copper strips.

Take 16mm input reducing down to 0.5mm as example:
16mm-10mm-7mm-5mm-4mm-3.6mm(annealing)
4mm-2.4mm-1.7mm-1.5mm(annealing),

1.5mm - 0.9mm- 0.65mm - 0.5mm

total 11passes rolling
