The oil to be applied enters the A cavity of the blade and overflows from a range of small holes 6 drilled flow throught the blade wall reaching the shatp edge 3 Fig. The industrial frequency operated oil filled conventional generators employing selenium rectifiers and big capacitors require strong currents, up to 2 mA.

The output of the metering pumps candy optionally controlled by precision flowmeters mounted downstream of the metering pumps reaching a new standard of precision electrostafic this class of machines. ISO Not Specified. Therefore at the maximum rated voltage of kV a W power is involved. TDC’s electrostatic oilers deliver the most uniform targeting and control of oiling possible.

In order to provide you the best suitable solution electtostatic discuss special requirements, please get in touch with us.

Electrostatic oilers – Technical specification

The orifice dia is about 10 times wider than the conventional slot blade which is virtually self cleaning and mantenance free. The deposited droplets loose immediately their electric charge so that no evidence electrostxtic the electrostatic deposition process is left on the coated surface. The excess oil particulary when the strip is narrow compared to the blade length is collected in a bottom sump provided with levels and then the sucked in by a recovery pump, filtered and eldctrostatic to the storage oil tank.

We shortly remember the principles of electrostatics for the readers which are not familiar with this type of application. Stay up to date on industry news and trends, product announcements and the latest innovations.


Electrostatic Oilers

Terronics electrostatic oilers provide a better way to oil steel strip for rust protection, lubrication, or stamping. Control and instrumentation can be located on coater assembly or remotely.

Sheets and strips might already corrode shortly after production or processing, i. Maintenance – Maintenance requirements are generally minimal, stemming from the system’s elegant, low-energy design and extensive industry testing and operation. These blades are heated by circulation of an indipendent diathermic fluid through two channels drilled through the two halves of their steel body. Oil Reservoir System – Sized according to the desired deposition thickness, strip width, and line speed.

For safety, mechanical protection and good housekeeping the blades are mounted in a suitable enclosure fig. Contact systems are always affected by the uneven flatness of the surface which causes uneven film thickness or dry stripes.

The Advanced Automation system can be interfaced to upper level computers when required via Profibus, Interbus and similar network systems. These are ideal tools for use at a typical Temper Mill where there is a big improvement over the conventional contact absorbent roller most often used in this situations and where a very high oil output is required. Thomas Industry Update Stay up to date on industry news and trends, product announcements and the latest innovations.

Moreover fluid filaments or drops immersed in a strong electric field undergo the electrostatic pressure and break out in ever electrosratic electrically charged droplets which repel each other creating a finely atomized fluid mist.

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.

Deposition Control – Select desired coating weight across a range of more than System subassemblies include multiple 3 in.

Improves Safety and Housekeeping – Precise targeting and control eliminate overspray and reduce hazard and mess of oil runoff from coils, both for rolling mills and their customers. The machines can be moved out of the line, so that production is also possible without oiling.


Electrostatic Oilers

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. Moreover the oil deposited by conventional means is free flowing from the sites of coils severely contaminating storage floors.

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. Reduces Customers Oil Disposal Problems – Less oil applied means that your customers pay less to remove and dispose of oil. Custom manufacturer of automatic electrostatic oilers.

Electrical charges of the same name repel each other, electrical charges of electristatic name attract each other. Coil Width – From 6″” in existing installations. We supply a standard two generators, one for each blade to take advantage of the much profitable opposite polarities systeme: The enclosure is provided with clear inspection doors interlocked with the high voltage source and with electrosattic oil feeding pumps. Systems with different tanks for various oil types are available.

With this blade design it is possible to apply very viscous products or sometimes products wich are solid at room temperature.

Ojler are several advantage with this design. Minimizes Oil Usage – Can reduce oil usage to as little as one-fifth of currently applied levels. The topsite blade is fitted with a non conductive insulating mask to limit the current drain within 50 microAmps. Moreover it is possible to install special automatic earthing device to quicky discharge the residual charges whenerver the generator is turned off. The system is ideal for application of very low coating weights of DOS or similar products normally required on Tin-plate, Black-plate and Aluminium lines.
