Detailed Product Description

Copper Bronze Brass Sheet Strip Cold Rolling Mills

 

Copper (Bronze, Brass) Strip Rolling Process:

  • From hot rolling and cold rolling, hot rolling from billet down to around 17mm thickness by 2hi mill
  • the copper cold rolling mill will be first rough rolling mill to get around 3mm sheet by 4hi roughing mill
  • from 3mm go to around 1mm thickness by 4hi reverse mill
  • then fine rolling mill makes copper strip and even copper foils by 4hi or 6hi hydraulic AGC reversible mill.

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 1.5mm as example:
16mm-10mm-7mm-5mm-4mm-3.6mm(annealing)
4mm-2.4mm-1.7mm-1.5mm, total 8passes rolling

Copper(bronze, Brass) and copper alloy Strip plates are widely used in industries of electronics, automobiles, electricity, home appliances, etc.to make parts like electric elements, light holder, battery cap, buttons, seals, li-ion battery, etc.

 

 

Hydraulic AGC press down system to press copper thickness down to min. 0.03mm, high precision high precision reaction of the hydraulic AGC automatic control system plays critical role:

Composed of 2 hydraulic cylinders for press-down, servo hydraulic system, PLC system, thickness gauge, industrial computer, etc. The PC also shows the drivers PLC parameters for operation and saving.

 

Functions:

① Manually press-down or come up

② Roller gap position control

③ Monitor closed control

④ Pre-feedback closed control

⑤ Pressure closed loop control

⑥ Two hydraulic cylinders in synchronization

⑦ Two hydraulic cylinders in inclination control

⑧ Roller gap zero control

⑨ Mill rigidity measuring control

⑩ Nonlinear compensation control of Servo valve flow and press-down margin control of hydraulic cylinder press-down. 

⑪ Acceleration, deceleration compensation control加,

⑫ Roller gap and thickness manually adjust

⑬ Overload protection control of pressure and pressure difference.

⑭ Overload protection control of Roller gap difference overrun

⑮ Fast open/close control
