Home > Products > Three-Roller Cold Pilger Mill > LD40 Series Three-Roller Cold Pilger Mill

Introduction

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 .
