Multifunctional 2 Roller Cold Metal Rolling Mill For 20mm - 8mm
Metal Wire
Feature
1. The machine is for rolling. The rod after rolling can greatly
improve mechanical property and remedy defect from casting. This
speed can reach to 5m/s for this series.
2. The most important thing of mental process craft is forming
system technology. It plays a more and more remarkable role in
modern manufacture process, at the present, the rolling machine
usually use big motor or huge and bulky multistage mechanical
transmission mechanism. The mechanism depends on fixed gear and
belt for transmission and limit the speed of rolling for process
unit and transmission mechanism. This system can only make single
material. For example, copper rod mill can not roll aluminum rod.
Different section need special machine to make, present system can
not process special ally machine and so on, meanwhile,big
transmission cases drive some frames to work but excessive current
will waste more resources. Transmission system in cases will happen
to abrasion when it has ling time to work, in the process, it may
have some problems for instability, push and pull to influence
product quality. Besides, process device and mechanism are setting
not reasonably. It may take a lot of time and increase worker’s
diffculties to change the roller. We need to reform and innovate
available equipment because it will not meet modem enterprise’s
requirements, from the market survey and demand, we haven’t have
this practical application.in order to meet the demand of market,
we must develop a mental machine system with multifunctional and
small cross section.
3. The machine designed by us is each stand driven by separate
frequency motor or servo motor, so each stand still is sync after
changing the rolling pass of and rotation speed. Process roller can
change the pass, and each rotation speed can be set on touch
screen.thus, under the premise of meeting stand’s
strength,two-roller cold rolling mill can roll different size of
copper rod. Different material also. Like 17mm-8mm,or 14.4-8mm,or
12.5-6.8mm or 8-4mm. Its same like Germany’s.

some questions maybe you are interested in
1.What’s the system about Two-high mill and 3 roll mill?
Two-high mill pass system for: ellipse-round hole type system ;
Three roll mill pass system : triangle -round system
2.The roundness of outlet rod is very big by the rolling mill,is it
right?
NO, no more than 2mm.
3. Is it very difficult to operate the rolling machine ?
No.just need one person and the machine is very easy to be
operated.
4 .what’s the main different between rolling mill and extrusion
machine?
Rolling mill belong to cold process,extrusion machine belong to hot
process.
