The Φ130/Φ350×350 4-Hi Reversing AGC Cold Rolling Mill is 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 Φ130/Φ350×350 4-Hi Reversing AGC 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 Φ130/Φ350×350 4-Hi Reversing AGC 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.

Q1: What types of materials can the mill process?
Hot rolled low carbon steel strips.
Q2: What is the thickness range for input materials?
The mill can handle input material thicknesses up to 2.0mm and produce finished products as thin as 0.5-1.4mm.
Q3: What kind of automation features does the mill have?
The mill is equipped with an Automatic Gauge Control (AGC) system for precise control of the rolling process, including hydraulic control of the press-down system and thickness gauge pre-control.
Q4: How does the AGC system enhance performance?
The AGC system allows for tight thickness tolerances, achieving stable rolling within ±4.5μm for 0.3mm thickness and ±7μm for 0.5-0.8mm thickness.
Q5: What safety features are included in the design?
The mill incorporates various safety features, including overload protection and emergency stop mechanisms to ensure operator safety during operation.
