LD40 Series Three-Roller Cold Pilger Mill
  • Introduction
  • LD40
  • LD40 Hydraumatic Type
  • LD40 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 mandrel 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. It is convenient to change and maintain the roller. 
5. Monofilament thread rod feeding way is stable and which is assisted by the top tray rotation . 
6. The Mairtai type rotary feeding way is precise , stable and reliable .
