When producing large quantities of tubing, cold drawing is considered to be very slow, compared to the pilgering process. As an example, a cold drawn tube may have to be drawn 3-4 times to equal the same amount of work of a pilger mill. Each time a tube is cold drawn, the tube must be cleaned and annealed (softened) before drawing again.
Alibaba offers 73 cold pilger mill products. About 52% of these are rolling mill, 24% are cylindrical roller bearing, and 6% are stainless steel pipes. A wide variety of cold pilger mill options are available to you, such as cold rolling mill, hot rolling mill, and roller.
The invention relates to a cold pilger rolling mill (7') for cold-forming a bloom (11) to form a cold-hardened pipe (25), comprising a roll stand (1) having rollers (2) rotatably mounted thereon.
