Introducing cold pilger mill technology An overview of the equipment and the process. The Tube & Pipe Journal July/August 2006 July 11, 2006 By: Oliver Strehlau The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent.
Used attributive with reference to a rolling mill for reducing the outside diameter of a tube without changing the inside diameter, its two rollers each having a semicircular groove of decreasing diameter passing round the circumference, so that in conjunction they form a circular hole through which the tube can be forced on a cylindrical ...
Meraj Engineering is the supplier of pilger mill and cold rolling products in India. Pilger mill is a metalworking process in which metal is disfigured by passing it through rollers at a temperature below its recrystallization temperature.
Cold rolling of tubes in pilger mills is a cyclical process that is commonly used in manufacturing of tubes made of hardly deformable alloys. In the classic solution, the rolling stand is mobile and moves to-and-fro, and the rollers move with the stand, while turning in opposite directions.
