Production characteristics of cold processing tube unit

- Jun 12, 2020-

The production characteristics of the cold processing tube unit are that the tube material is usually subjected to multiple cold deformations and work hardening from input to processing into a finished product. Therefore, the entire production process is composed of multiple preparation processes and deformation processes, and has the characteristics of reciprocating circulation, so there are many processes The production cycle is long, the metal consumption is large, the production efficiency is low, and the general production scale is not large.

Configuring cold drawing and cold rolling mills in the unit at the same time is beneficial to exert their respective advantages, especially for the production of high alloy steel pipes such as stainless steel and non-ferrous metal pipes that are difficult to deform. Cold drawing machines include single and multiple straight pipe drawing machines and reel pipe drawing machines (see Reel Pipe Drawing). The length of the tube is up to 50m when a single root is cold drawn, and up to several hundred meters when the reel is drawn. The minimum tonnage of the cold drawing machine is 30kN, and the maximum is 7000kN. Conventional cold rolling mills include two-roll cold rolling mills and multi-roll cold rolling mills.
