LD60 Series Three-Roller Cold Pilger Mill
  • Introduction
  • LD60
  • LD60 Hydraumatic Type
  • LD60 Machinery Type
1. The main conveying system is with V belt which can make sure equal force , creditable and stable function . 
2. The precision of steel pipe is high enough to be manufactured thin-wall pipe with three-roller . 
3. The rolling mill adopts edge feeding way removing the 脱芯棒 comparing to the side feeding . The exact location of mandrel on the deformation zone and short rolling line not only  suit for rolling long tube billet but also improve the roller’s efficiency .
4. Electric-control feeding and discharging way improve the working efficiency .
5. It is easy to change and maintain the roller . 
6. Twin-wire feeding way realize the stable feeding. 
7. To tighten with hydraulic mandrel lowers the labor strength .
8. The Mairtai type rotary feeding way is precise , stable and reliable .
