The 700mm 4-Hi 2-Stand 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 700mm 4-Hi 2-Stand Continuous 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 700mm 4-Hi 2-Stand 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.
