The 850 MM 6 Stand Carbon Steel Continuous Cold Rolling Mill is a multi-stand cold rolling mill designed for the production of
cold-rolled steel coils. It has a rolling width of 850 mm and
consists of 6 rolling stands. The mill uses a mechanical screwdown
system to adjust the roll gap and control the thickness of the
final product.
- Four-high rolling configuration for precise thickness control;
- 6-stand continuous rolling process for enhanced productivity;
- Robust construction with heavy-duty work rollers and backup
rollers;
- Intelligent automation and process control for consistent
quality;
- Capable of handling materials from 2.0mm to 0.18mm thickness;
- Maximum rolling speed up to 480 m/min for high throughput.
- Capability to handle a wide range of carbon steel grades, including
Q195, Q235, SPCC, SPCD, and SPCE.

The 850mm 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 850mm 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 850mm 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.
