20mm-8mm Two-roller cold rolling mill for oxygen free copper rod
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
products；
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.
