This listing offers a second-hand Fröhling 4-Hi cold rolling mill, model 4-HI, originally manufactured in 1969. The machine is currently dismantled and in storage as of 2018. It is designed for rolling alloy materials such as AA5050 and AlMg3 from series 3000 and 5000. The maximum strip thickness capacity is 20.0 mm, with an output thickness range from 0.25 mm to 1.20 mm. The mill supports a maximum rolling speed of 400 meters per minute.
The rolling mill features four rolling stands equipped with work rolls and backup rolls. The backup rolls have a diameter of 390 mm and width of 335 mm, while the work rolls measure 130 mm in diameter and 340 mm in width. The coil size accommodated by the mill ranges from an inner diameter of 400 mm to an outer diameter of 1500 mm.
The drive system includes DC motors with ABB converters installed in 2004, providing 200 kW power to drive the work rolls. Cooling is managed by an emulsion filtration system provided by Laval. Control systems include an ABB SCADA PLC system, with flatness control and hydraulic automatic gap control (AGC) on stand #4. Stands #1 to #3 have mechanical manual thickness control.
Utilities required for operation include electrical voltage, 5 bar compressed air, and cooling water. The machine has a total of 39 work rolls and backup rolls combined.
Visually, the machine includes a large control panel with multiple buttons, switches, and displays. Four rolling units are positioned behind the control panel. A red and white striped safety barrier is installed in front of the control panel. The overall condition of the machine and control panel appears used but maintained.
