20mm-8mm Copper Rod Continuous Rolling Mill
I. major information
Mechanical design uses advanced crafts and high-quality materials,
such as roller; the appearance of the machine adopts German
design,which has higher work efficiency than other similar
II. Advantage of 2 high cold rolling mill
Rollers of each rolling stand are driven by separate inverter
motor. When the shape of the pass and rotating speed of each pass
stand roller are changed at the same time, each stand can operate
asynchronously. Processing rollers can change the shape of the
pass, and the gear ratio of each stand roller can be set on the
touch screen. So on the premise of meeting the stand strength,
2-roller copper rod cold rolling mill can roll different dimensions
of copper rod and also roll other materials.

1 main rolling mill
The main rolling mill is the important part of the continuous cold
rolling mill . It includes base, frame, reducer, motor etc. Each
frame is driven by an independent motor. All the basic rolling
process is finished on the main rolling mill, and the number of the
frames is different according to different rolling size.
2 guide system
each pass has entry and exit guide, odd frame of entry guide glides
to lead in, and even frame rolls to lead in.
guide material : GCr15
guide hardness: HRC55-58
3 pay off
max load capacity :3t
4 Coiling take-up machine
This machine consists of draught gear and take-up device, meets the
characteristics of taking-up enclosure and requirements of constant
5 Oil lubrication system
oil tank capacity: 1m³
6 Emulsion system
In order to improve the surface quality of the cold rolling copper
rod, emulsion cool and lubricate the roller , copper rod and guide
device in the rolling process.
7 electrical system
The electrical system includes the power system and the controlling
8 feeding and straightening device
The feeding and straightening device is in front of the main
rolling mill, and it is used to straighten the rods so that it can
feed the rod easier.
