Cold Rolling Section                                                                                      Cold Drawing Section


 Cold rolling and cold drawing line is a whole cold processing line, further process of hot rolled pipe or welded pipe, 

to produce pipes by cold rolling, cold drawing or cold rolling and cold drawing combined. Basic technical flow is like

 this: 

(1) Pipe supply: usually mother pipe is finished or semi-finished hot rolled pipe, extruded pipe and welded pipe.

(2) Pipe prepare: including inspection, packing, pickling, cleaning, washing, neutralizing, drying, lubricating and so on.

(3) cold processing: cold rolling or cold drawing. 

(4) Finished pipe finishing: including heat treatment, straightening, sampling, end cutting, testing (manual inspecting

 and all kinds of testing), hydraulic testing, oiling, packing and entering into warehouse, and etc.

Characteristic of cold pressing line is that it needs several times of deforming and hardening from mother pipe to 

finished pipe. So the whole production is cycling, composed of several times of preparation and deformation. That is

 why production cycle is long and normally such kind of mill is of small scope.


Two-Roller PilgerMill


 

Two roller full ring die pilger mill is used in rolling differentmaterial (C.S., alloy steel, S.S., copper& copper alloy, rare metals, etc.)tubes in cold condition. Tubes by pilgering has the advantages of highprecision, good surface, big reduction, etc. It is a quite popular way ofproducing seamless tubes.



Multi-Roller PilgerMill


 

Multi-roller full ring die pilger mill is used in rolling different material(C.S., alloy steel, S.S., copper& copper alloy, rare metals, etc.) tubes incold condition. 
Tubes by pilgering has the advantages of high precision, good surface, bigreduction, etc. It is a quite popular way of producing seamless tubes.
