Rolling Mills are used to improve quality and thinning the metal strip. We offer Cold Rolling Mills suitable for SECONDARY and FINISH ROLLING of strips of carbon steel, stainless steel, alloy steel, aluminium and copper.

* Stable driven, high rolling speed, big rolling force and high precision.

4-High Cold Rolling Mill uses working rolls and 2-back-up rolls to support action. It allows for input material to be <5mm and finished product to be e.g. 0.15mm thickness.

6-High Cold Rolling Mill uses working rols, intermediate rolls and back rolls, resulting in high precision and good shape of material. It allows for input material to be <5mm and finished product can be e.g. 0.1mm thickness.

* Small tension in horizontal and vertical directions can produce high-precision steel strip, level, stable,

controllable shape, highly-smooth steel strip

* Increased pushing volume and decreased quantity of stands

* Smaller diameter of working-rolls and less milling, smaller milling strength required

* Saved rolling cost: reduced energy consumption, improved rolling efficiency, yield and qualified products rate

* Reduced intermediate annealing or increased belt blank thickness, extended width and thickness of belt

* Adopting horizontal-roll can decreases consumption of spare parts for rolls

* Reduced cutting volume, broke phenomenon, and rate of waste products

Multi-Machine set Cold Rolling Mills are well designed and have configuration, allowing for easy operation and resulting in higher output production quantity than 4-Hi-reversing mill, or 6-Hi-reversing roller mill. The Set consists of many components, such as 2-5 units with rolls, including 4-rollers, 6-rollers, transmission of the working rolls, transmission of the supporting rolls, in 4-roller or 6-roller combinations.

Other Multi-Roll Cold Rolling Mills could be offered, depending on requirements of the Customers.

We offer also other New & Used machines

for: EPS / PU / Mineral Wool Sandwich Panel, Roll-Forming, Slitting,

Cut-to-Length, Tube, Pipe Lines, Rolling Mills, Descalers

for Steel Industry, Foundry and Sandwich Panel Industry
