Those mills can have from 3 up to 6 rolls; every set of mills is called a tandem mill or mill train. To improve the milling extraction efficiency, imbibition water is added at each mill. Hot water is poured over the cane just before it enters the last mill in the milling train and is recirculated up to reach the first mill.
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to ...
We utilize this approach to produce a world class Multi Blank line with the following key features: World Class Herr-Voss Stamco leveling technology; Proprietary Feed roll design for non-marking surface critical material, featuring our Electro Discharge Texturing (EDT) finish; High Speed High Accuracy Shearing
Electro Discharge Texturing (EDT) EDT is a process for surface treatment of work rolls of the cold rolling industry. Using different electrode materials (copper, graphite .), different polarity and modes (capacitive or pulsed) surface roughness's between 1 and 16 µm can be achieved over the total body length. Different surface treatments ...

The particular electrical discharge texturing (EDT) technique used affords a high degree of process control compared with more conventional methods and, therefore, optimisation of roll texture is possible through the selection of the appropriate operating variables.
We also provide turn-key on-site or off-site roll shop management for both hot and cold rolling mills where we supply labor and capital resources for the roll shop construction and ongoing maintenance. In the area of cold rolling, we provided EDT (Electro-Discharge Texturing), roll .
Surface texture of a temper mill work roll plays an important role in steel sheet production. Electrical discharge texturing (EDT) is a common texturing method to meet the strict
Jul 15, 2000· However, EDM technology has gotten better, too. One company with a perspective on how these processes compare is Makino (Mason, Ohio), a builder offering machining centers and EDM machines both. Billy Grobe is die/mold operations manager for this builder, and he often advises customers as to which metal removal process makes sense for their work.

Currently, shot blasting (SB), laser beam texturing (LBT) and electrical discharge texturing (EDT) are the three principal methods used to texture mill rolls, however, electron beam texturing (EBT) is being evaluated. Although widely used, conventional SB has major limitations due to the lack of adequate process control and its inability to ...
The micro-geometry of the roll surface has significant influence on the final quality of the rolled metal plate. In this paper electro-discharge texturing parameters are analyzed, for ...
A ball tube mill may be described as a cylinder made of steel plates having separate heads or trunions attached to the ends with each trunion resting on suitable bearings for supporting the machine. The trunions are hollow to allow for the introduction of discharge of the materials undergoing reduction in .
Summary. The paper gives the results of a series of tests aimed at evaluating the effect of the electrical discharge texturing (EDT) process on the surface integrity of mill work rolls using two different electrical generator and dielectric flushing arrangements.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
For some of our customers, the quantity of rolls they need textured is too small to warrant the investment in dedicated Sarclad EDT. However, the advantages of electro-discharge textures can still be obtained by making use of our in-house roll texturing service.
After this, research has been done for the effect of EDT (Electric Discharge Texturing) on Formability of Aluminum Automotive Sheet. In today's automotive industry there is no consensus regarding this effect. European car manufacturers use EDT treated aluminum sheet for .
Roll Surface Technologies (RST) provide hard chrome plating, steel / polyurethane / rubber roll grinding, electro discharge ( EDT) roll texturing, chock maintenance and inspection as well as a diverse range of other services such as plant maintenance, roll turning and repair, and in plant coil logistics solutions.
