In its program, Production and Engineering Company ENCE GmbH (ЭНЦЕ ГмбХ ) highlights the most significant metallurgical equipment; this equipment. Ravarini Castoldi our has been making electrostatic equipment since under the ELETTROSPRAY® trademark. Manufacturer of standard and custom electrostatic automatic oilers for the metal processing industry. Products include blade systems, rotary atomizers, and.
The opposite polarities electrostatic charging system we are now proposing as electeostatic avoids over oiling the strip edges and greatly reduces the escape of oil mist from the enclosure pass line windows.
This mist when opposed to an earthed surface is attracted and evenly settles and firmly adheres on this same surface.
Positioning System – Spray header can move on and off line via a variety of retraction mechanisms. Moreover because of a much lower capacity of the system the energy stored and released in case of a spark is much lower. The blade edge is formed as a single plane, externally wetted from a row of holes uniformly spaced along the blades body.
Spraying systems are always associated with a more or less pronounced overspray which impairs the deposition rate, polluting in the same time the working site. Obviously, we also design and build electrostatic oilers for later deep-drawing applications for instance can-stock material or to apply hot melts especially for automotive materials. In practice the fluid mist is negatively charged and the metal surface is kept at ground potential connecting it to the mass, which is very easily done due to the presence of large metals structures in every process line.
The easiest way to prevent corrosion is to treat the surface of the thin sheet with special anti-corrosion oils.
Electrostatic Oilers Suppliers
As a first in this field the bells revolutions are electronically controlled. Oil application is possible from both top-down and bottom-up orientation. Sheets and strips might already corrode shortly after production or processing, i.
Custom manufacturer of automatic electrostatic oilers. The oil level is precisely monitored and is automaticaly filled at low levels from the electtostatic bulk supply.
Minimizes Oil Usage – Can reduce oil usage to as little as one-fifth of currently applied levels. Mechanical methods of oil deposition rolling, dripping, pumping, blade wiping as well as most semi-electrostatic methods are imprecise and require over-oiling to ensure total strip coverage.
With the most modern electronic generators the same results are obtained employing ma 0. TURBODYN rotating bell units First developed for use as a paint electrosttatic for automotive manufacturers, the system has been modified to apply extremely low oil quantities to ferrous and nonferrous strips. Normally the atomised oil produces a circular pattern on the strip of approximately mm effective diameter, with up to three atomisers positioned each side of the strip.

Installation – Units are freestanding, ready for operation after connecting utilities. Special insulating fenders or plates protect electrostatid blades against accidental strip impacts. In order to provide you the best suitable solution and discuss special requirements, please get in touch with us.
Threading tables are normally driven by air cilynders. The atomising edge of the underside blade is twice the length of the topsite blade to ensure the highest possible atomising density electrostwtic transfer efficiency and is designed specifically to overcome the “flooding” common with conventional slot blades.
The side walls of the cabin are lined with highly insulating plastic plates wich act as electrostatic refectors.
Improves Coil Handling – Reduces telescoping of coils. Flow control or monitoring can be provided optionally but is not considered to be essential to the performance of the machines and set a new standard of automation in this electrostahic of machines.
The machines can be moved out of the line, so that production is also possible without oiling. Maintenance – Maintenance requirements are generally minimal, stemming from the system’s elegant, low-energy design and extensive industry testing and operation. In any case oil flows from the atomiser in form of cuspid wich under the effect of the electrostatic pressure break in tiny droplets forming a curtain of very fine oil mist.
The rules electrkstatic selection are generally oilre and the best type of atomiser fot the application to hand would usually be assed on a one-to-one basis.
Manufacturer of standard and custom electrostatic automatic oilers for the metal processing industry.
There are several advantage with this design. Typical Line Speeds – Up to fpm in existing installations, higher speeds are possible. Oil Characteristics – System can accommodate virtually all non-water based fluids used in this application. Additionally to our portfolio for complete strip processing lines and revamping of existing lines, we provide various auxiliary equipment to be electrostahic in cold rolling mills and metal strip production and processing plants.
For safety, mechanical protection and good housekeeping the blades are mounted in a suitable enclosure fig. Most existing methods are ineffective and cause oil handling headaches.
An Operator Panel displaying status of functions and alarms is supplied as standard. Moreover the oil deposited by conventional means is free flowing from the sites of coils severely contaminating storage floors. The enclosures can be made stationary or extractable from the line running oilee suitable rail driven by a brake gearmotor. Anticorrosive coating for sheets and strips Electrostatic Oilers Additionally to our portfolio for complete strip processing lines and revamping of existing lines, we provide various auxiliary equipment to be used in cold rolling mills and metal strip production and processing plants.
