Two Roll Precision Straightening Machine RJE Series

 

Finishing Solution Provider|Straightening Machine|Peeling Machine
As a key machine for bright steel production, RJE series of two roll straightening machines are capable to straighten and polish peeled or cold-drawn long round bars and D/S≤15 thick-walled tubes with diameters between 3 and 160mm. Thes cross-roll vertical machines have one upper concave roll and one convex roll, which are separately driven; therefore, RJE series of two roll straightening machines are capable to machine bars and tubes at a high speed and with accuracy. These machines can be combined with an automatic bundle charging table and discharging table; therefore, bars and tubes can be unbundled, fed, straightened, carried out, and then collected consecutively and automatically.
 
Advantages
  • Optimized concave and convex rolls and linear contact allow full length straightening;
  • Constant voltage load control system ensures necessary straightening force and protection in case of overload;
  • The speed of major transmission system is infinitely variable, making the speed easy to control and the machine easy to be deployed with other machines with different speeds;
  • Roll clearance and angle can be adjusted using an electric/hydraulic-driven closed loop where encoder feedback is used; the adjustment is highly precise and repeatable;
  • Roll clearance and angle adjustment is displayed on the touch screen on the console;
  • Straightening technical parameters are stored in groups for easy retrieve, reducing time of changing for bars with different specifications;
  • Integration of mechanical, electrical, hydraulic and air components and PLC control enable automatic circulation.

 

 
Applications:
  • Producing high-quality and defect free bright steel;
  • Straightening round bars before peeling in the finishing line;
  • Processing plain carbon steel, alloy steel, special steel, copperand its alloy, 

Ti and its alloy, and silver, Ta, Nb,and Hf bars and tubes for nuclear power plants.
