The 1380mm 6-High Reversing Cold Rolling Mill is a
high-productivity cold rolling mill designed for processing carbon
steel strips. It utilizes a single-stand, reversible configuration
with a hydraulic Automatic Gauge Control (AGC) system. This
reversing cold rolling mill is designed to produce high-quality
cold rolled carbon steel coils with excellent thickness and
flatness tolerances, making it suitable for a wide range of
downstream applications.
- Hydraulic AGC system with functions like constant roll gap
control, constant roll force control, constant thickness control,
and tension/speed control.
- Positive and negative bending of the work rolls, and positive
bending of the intermediate rolls for shape control.
- Intermediate roll shifting mechanism for compensation of strip
width and shape variations.
- Double-station roll changing carriage for quick work roll and
intermediate roll changeovers.
- Air-oil lubrication for the roll system, turning rolls, and oil
removal rolls to improve bearing life and reduce maintenance.
- X-ray thickness gauge for precise thickness measurement and
control.
- Fully integrated digital automation and control system utilizing
PLC, AC drives, and remote I/O.

The 1380mm 6-Hi Hydraulic AGC Reversing Cold Rolling Mill widely used in industries such as steel, aluminum, automotive,
aerospace, and electrical appliances. It enables precise and
efficient metal processing, providing high-quality products with
controlled thickness, improved surface finish, and desired material
properties.
Packaging:
All parts of the 1380mm 6-Hi Hydraulic AGC Reversing Cold Rolling
Mill are fixed inside container by steel wires and special PET
straps, in order to make sure all parts will not move during
transportation and avoid any kinds of damage of machine and
container.
Shipping:
Sea Freight: The 1380mm 6-Hi Hydraulic AGC Reversing Cold Rolling Mill is often shipped via ocean freight, especially for international
transportation. The equipment is securely loaded into shipping
containers or flat racks, which are then loaded onto cargo vessels.
This mode is suitable for long-distance shipping and can
accommodate larger and heavier cold rolling mill.
Air Freight: When there is a need for fast delivery or for shipping smaller or
lighter cold rolling mill, air freight can be used. The equipment
is packed and loaded onto aircraft for transportation. Air freight
is typically more expensive than ocean freight but offers quicker
transit times.
