Jul 11, 2006· The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.
1. Introduction 1.1. Lubrication in cold extrusion of steel parts. Lubrication plays an important role in cold extrusion since efficient lubricants prevent direct metallic contact, with the reduction of extrusion loads and wear, and the improvement of products quality and tools life.
Hot Extrusion: Hot extrusion is done at fairly high temperatures, approximately 50 to 75 % of the melting point of the metal.The pressures can range from 35-700 MPa (5076 - 101,525 psi). Due to the high temperatures and pressures and its detrimental effect on the die life as well as other components, good lubrication is necessary.
3) (a) JSM Automatic Programmable Sheet Lubrication System & (b) JSM Automatic Programmable Spray Application System for In - Die Lubrication for Rolling Mill. This is a system, which combines roller lubricator at the entry of coil stock and with downstream spray nozzle.
The production of a copper tube starts with a warm forming process. Typically, cast billets of 100–500 kg weight, depending on the final tube size, are inductively heated to ca. 900 °C and immediately extruded to seamless hollows.
The Dropsa air-oil lubrication system has5-Stand Tandem Cold Mill to lubricate the bearings and seals positioned inside the Working Roll / Intermediate Roll / Back-up Roll chocks. The function is achieved by using Dropsa's SMX progressive dividers, tailor-made splitter tubes, cutting-edge control panel and .
The extrusion will have a 1 mil thick layer of glass, which can be easily removed once it cools. Another breakthrough in lubrication is the use of phosphate coatings. With this process, in conjunction with glass lubrication, steel can be cold extruded. The phosphate coat absorbs the liquid glass to offer even better lubricating properties.

Extrusion is a manufacturing process in which a compressed material is forced to pass through a die having the section of the part to be made. This operation allows for continuous production of long products (tubes, pipes, profiles) at a fast rate. Extrusion gives parts with even more precise shapes than are possible with stamping or die forging.
