Review on Solventless Magnet Wire Lubrication by Means of Wax-Impregnated Textile Yarn

WCTI 979 Views

Mechanics of Magnet Wire Handling – Imagine an enameled wire, which is pressed to a plane with a load Fz, the friction force to overcome in order to move the wire is a function of Fz. For dry, solid sliding surfaces, the friction force is independent of the speed v of the movement, which is also true for wires lubricated with wax or wax-like materials. Lubrication with oil or grease results in viscous floating, which is dependent on the speed of movement.

Rod Wire Pickling & Phosphating

WCTI 909 Views

The steel material phosphating process has the purpose to produce a surface conversion layer, at thin and compact thickness strongly anchored on the surface, in order to facilitate the cold deformation or the further drawing operations. It exists with different types of phosphate. For rod wire, the most frequently used is the zinc phosphate. After phosphating, an opportune covering with lubricating layer on the phosphated surface is necessary

In-Line Annealing Process – As Important as the wire drawing process itself

WCTI 873 Views

Considering the downstream process from rod to fine wire, be it single or multi-wire production, the in-line annealing process is as important as the wire drawing process itself, because it must ensure the required mechanical and electrical properties (elongation, mechanical strength and conductivity), maintain the wire diameter and roundness defined by the final die, and for metal-plated wires, ensure the integrity of the wire coated surface

Rotating machines such as stranders, bunchers, twinners and cablers use flyer bows to produce helically twisted wires, conductors and cables. All products being processed on these machines come in contact with the bow. More than half of the power required to run the corresponding machine goes toward rotating the bows. In addition, a good amount of the noise generated by a rotating machine comes from the bow, and less aerodynamic bows usually make more noise. Consequently, these bows are pretty important, and they are a main factor in determining the level of success in your rotating equipment operations.

Wire Rod Coils for International Transport

WCTI 732 Views , 

Turkish steel manufacturer, Kardemir (Karabük Demir Çelik Fabrikalari A.S.), based in Karabük, has placed an order with SMS group for the replacement of selected key components of its wire rod mill. The wire rod mill to be modernized is part of the SBQ (Special Bar Quality) plant supplied by SMS group in 2013, which has an output of 700,000 tons of bar steel, bar-in-coil and wire rod every year.
