Hot Cold Aluminum Rolling Mills For Aluminum Coil Sheets From Aluminum Slabs
Aluminum Hot Cold Rolling Mills for Aluminum Coil Sheets from Aluminum Slabs
Aluminum Sheet Rolling Process:
- Aluminum slab casting from aluminum ingots.
- First make Hot rolled aluminum coils from 2Hi Reversible Hot Rolling Mill
- aluminum sheet cold rolling mill is one way rolling mill, including uncoiler, entry processing table, 4hi mill, exit processing table, recoiler, oil coolant supply system, fire fighting system, etc.
As per finished aluminum sheet properties and quantity, can calculate out thickness reduction degree, number of rolling passes, raw slabs dimensions, production capacity, etc.
- 2-Hi hot Rolling: from 200-300mm thickness to 10mm
- 4Hi One way mill: from 7-10mm to 0.5-3mm
- 4Hi One way mill: to make aluminum foil.

Configuration:
- Mechanical press down, with displacement sensor, to achieve the opening degree input automatically adjusted.
- Hydraulic cushions can be single side or both sides adjusted to press down.
- Emulsified liquid to cool rollers can be controlled.
- Hydraulic balance control of work rollers
- Hydraulic rollers changing
- Four row short cylindrical roller bearings for work rollers
- To adapt big torque rolling,the main mill gears and recoiler gears are hard teeth face gears.
- The gearbox can bear heavy load and provide high precision transmission, stable working with little noises.
- Electric control system has complete fault alarms and breakdown diagnosis functions.
- DC drive is all digital SCR rectifying device.
