Narrow Strip Oilers

 

Terronics electrostatic oilers provide a better way to oil steel strip for rust protection, lubrication, or stamping. Most existing methods are ineffective and cause oil handling headaches. 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. This leads to high costs of oil removal, disposal coil handling problems and safety/housekeeping problems from runoff of excess applied oil both for you and your customers.

 

 

System Benefits

 

Preserves Product Quality - Precise targeting provides total strip coverage.

 

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.

 

Reduces Customers Oil Disposal Problems - Less oil applied means that your customers pay less to remove and dispose of oil.

 

Improves Coil Handling - Reduces telescoping of coils.

 

Minimizes Oil Usage - Can reduce oil usage to as little as one-fifth of currently applied levels.

 

Allows Flexible Processing - Oil application is possible from both top-down and bottom-up orientation.

 

 

Operating and Design Information

 

Oil Characteristics - System can accommodate virtually all non-water based fluids used in this application. Viscosity: 1-2000cps, Resistivity: 10⁷-10¹⁰ ohm-cm.

 

Typical Line Speeds - Up to 4000 fpm in existing installations, higher speeds are possible.

 

Coil Width - To 6" with base model. Contact TDC if wider widths are required.

 

Typical Deposition - Less than 50 mg/ft²/side is all that is necessary for complete coverage.

 

Deposition Control - Deposition is tuned to each customers needs. Contact TDC if precise variable control is required.

 

Installation - Units are freestanding, ready for operation after connecting utilities. Compact design fits into most lines without modification to existing equipment.

 

Start Up - Assisted by TDC engineers and designers who remain on-site through successful start-up and operation.

 

Maintenance - Maintenance requirements are generally minimal, stemming from the system's elegant, low-energy design and extensive industry testing and operation.

 

Power - 120 VAC, xx Amps for base model.

 

 

System Subassemblies

 

Control System - xxx

 

High Voltage System - Low-amperage source, typically operated at 25-35KV, is used to power the nozzles and 5-10KV to power the inductor bars.

 

Oil Reservoir System - Consists of (1) oil reservoir with sight gage to view adequate level. (1) Metering pump providing flow to both upper and lower nozzle. Minor adjustment to the flow can be made with individual in-line flow controls for both upper and lower nozzles.

 

Oiler Assembly - Consists of (2) 3" or 6" nozzles, (1) for top-side oiling and (1) for bottom-side oiling. The oiling header is housed in an acetal enclosure with acrylic or polycarbonate windows to allow visual inspection of the spray. Any excess oil within the oiler is captured in the base of the housing and returned to the oil reservoir by gravity.
