Customized centrifugal cast steel sleeve for aluminum foil rolling mill
Typical operating conditions for GW precision products:
High speed precision rolling: Suitable for aluminum foil mills with rolling speeds of 1000-2500m/min (6-30 μ m foil), with a dynamic unbalance requirement of ≤ 0.2g · cm/kg.
Thermal mechanical coupling load: The instantaneous temperature in the rolling zone is 150-300 ° C, and it needs to withstand alternating thermal stress (with more than 10 cycles).
Micro level vibration control: suppresses high-frequency vibration (amplitude ≤ 0.5 μ m) during rolling of thin foil.
Adapt to device types
Sengemir 20 roll rolling mill: Production of ultra-thin aluminum foil (battery foil/capacitor foil).
Four roll high-speed aluminum foil finishing mill: Rolling of finished double zero foil (≤ 6 μ m).

Application scenarios of CrMoV centrifugal cast steel sleeve customized for aluminum foil rolling mill
CrMoV (such as 35CrMoV, 42CrMoV) centrifugal cast steel sleeves are designed for extreme working conditions of aluminum foil rolling mills due to their high strength, high temperature resistance, and fatigue resistance. They are mainly used for:
High speed precision rolling
Used for aluminum foil rolling mills (such as four roll and six roll mills), supporting the work roll/intermediate roll journal, suitable for rolling speeds of 1000~2000m/min.
Ensure that the thickness tolerance of ultra-thin aluminum foil (0.006-0.2mm) is ≤± 1%.
High temperature and heavy load environment
During rolling, the roller surface temperature should reach 150-250 ℃, and the sleeve should be resistant to thermal deformation.
Capable of withstanding rolling forces ranging from 3000 to 8000 kN and withstanding alternating impact loads.
Corrosion resistance requirements
Resist chemical corrosion of aluminum powder and rolling oil emulsion.
