The 750 MM 6 Stand Continuous Cold Rolling Mill is a highly capable and versatile cold rolling solution designed
for producing low alloy steel strips with a thickness range of
2-3mm. This mill features a 6-stand configuration, allowing for
progressive and effective thickness reduction in a single pass.
The mill is equipped with advanced features that enable
high-quality, high-efficiency production:
Customizable Design: The mill can be tailored to meet specific customer requirements,
ensuring optimal performance for the desired application.
Powerful Drives: The mill utilizes high-power DC motors, with 1000 kW for the main
machinery and 750 kW for the coiler, providing ample power for the
rolling process.
Precise Thickness Control: The mill incorporates a hydraulic Automatic Gauge Control (AGC)
system, which enables precise control of strip thickness, roll
force, and tension/speed, ensuring tight tolerances and consistent
product quality.
Advanced Automation: The mill's control system integrates PLC-based process control,
remote communication, and advanced functions such as strip tail
automatic deceleration, accurate stopping, and multi-point
stopping, enhancing operational efficiency and safety.
Versatile Rolling Capabilities: The mill can handle a wide range of low alloy steel grades, with a
yield strength up to 360 MPa, making it suitable for a diverse
range of applications.
Robust Construction: The mill's sturdy design, with a housing weight of around 70 tons,
ensures reliable and long-lasting performance, even under demanding
operating conditions.

The 750mm 4-High 6-Tandem Continuous Cold Rolling Mill is suitable for processing a wide range of materials, including
steel, aluminum, copper and copper alloys, nickel and nickel
alloys, titanium, and other non-ferrous metals. These materials are
used in various industries such as automotive, aerospace,
construction, electronics, and manufacturing.
Packaging:
All parts of the 650mm Four-High Five-Tandem 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 750mm 4-High 6-Tandem Continuous 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 continuous 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 is a continuous rolling mill?
A continuous rolling mill is a type of metal rolling mill that is
designed for high-volume production and continuous processing of
metal strips or coils.
Q2. What materials can be processed on a continuous rolling mill?
Continuous rolling mills can process a wide range of materials,
including steel, aluminum, copper, nickel, titanium, and other
non-ferrous metals.
Q3. How does a continuous rolling mill work?
Continuous rolling mills consist of multiple stands arranged in a
tandem configuration. Metal strips or coils are fed into the first
stand, and as they pass through each stand, the rolls progressively
reduce the thickness and increase the length of the metal.
Q4. What control systems are used in continuous rolling mills?
Continuous rolling mills are equipped with advanced automation and
control systems that monitor and adjust parameters such as roll
gap, rolling speed, temperature, and tension, ensuring precise
rolling specifications and maintaining product quality.
Q5. Can continuous rolling mills produce different sizes and shapes?
Yes, continuous rolling mills can be adjusted to produce different
thicknesses, widths, and shapes of metal strips or coils by
changing the rolling parameters and adjusting the mill
configuration.
