Precision of the tubes produced by drawing and cold rolling

2015
This paper presents the drawbacks of tube cold deformation classical processes such as drawing through stationary dies and cold rolling by rolls and rollers. Large assortments of cold-deformed tubes are produced by these methods. In order to increase their quality, several improvements of cold deformation methods have been suggested. At the first stage,

Modeling and Analysis of Cold Drawing Process

2017
Products of cold drawing process are extensively used due to their characteristics such as very good surface finish, close dimensional control and superior mechanical properties. Therefore, this process has drawn attention of several researchers over the years.

Cold Pressing and Drawing—The Metallurgical Aspect

Proceedings of the Institution of Automobile Engineers, 1934
The process of cold pressing can only be applied to the more ductile metals, and the greater part of the material so treated is in the form of thin sheets. Leaving out of account such exceptional materials as lead, a ductile metal is appreciably hardened in the process, losing some of its ductility and having its “elastic limit” raised.

Thermal Mechanism of Cold-Drawing of Polymers

1970
The phenomenon of cold-drawing (formation and steady propagation of an abrupt contraction — “necking” — in stretching cylindrical samples) is one of the qualitative peculiarities of polymers and plays an important role in the production processes of strong fibres [1–4].

A phenomenological theory of the mechanics of cold drawing

1984
When the amount of stretch in a taut fiber varies rapidly with distance z along the fiber axis, the tension T on a cross section normal to the axis is not determined by only the temporal history of the local stretch, but is affected by the variation of stretch with z.

Lubrication in Cold Rolling and Drawing of Pipe

Steel in Translation, 2018
The use of lubricant in the cold rolling and drawing of pipe is considered in theoretical and practical terms. Its use proves positive. The transfer of lubricant to the deformation region is analyzed, as well as the influence of the lubricant on the surface microrelief of the pipe. Experimental data and industrial practice are analyzed. Recommendations
