Spraying Systems Co.

• Unique mixing process provides uniform spray distribution and even cooling using less water and up to 25% less compressed air. Existing caster lines may be able to turn off some compressors and new lines may require fewer compressors

• Turndown ratio of 25:1 allows flow to be reduced using water pressures as low as 5 psi (.3 bar) without a loss in performance to accommodate a wide range of steel types and allows

• Large free passages allow contaminants to pass through the nozzle

• Ideal for slab and thin slab cooling

•  Superior spray distribution compared to conventional full cone nozzles

•  A full range of spray angles and capacities – change cooling parameters without the need to move manifolds

•  Staked vane stays in place, withstanding high heat and vibration to ensure a consistent spray pattern

•  Socket design provides for easy installation and maintenance with standard tools

•  Low profile allows nozzles to sit close to the header, to prevent debris from collecting or falling on the nozzle

• Affordable, automated solution. Operator intervention is minimized or eliminated – no need to have workers rotating handwheels

• Suitable for use with all brush-type headers up to 3" in diameter

• Easy operation. Cleaning cycles occur automatically when used with the programmable timer. Otherwise, activation requires a simple push of a button. The brushes wipe the nozzles and the dirty water is flushed away

• Control up to four headers with a single control unit. Options are available for controlling more Automatic Brush Headers with a single control unit upon request – the control panel can be integrated with the mill’s central control system via ethernet IP or used as a standalone control panel

• Easy installation. A brush header can be retrofitted from a manual wheel to automatic operation with just four bolts and an insert adaptor pin

• Virtually maintenance free. Aside from gear lubrication once a year, the Automatic Brush Header requires no maintenance

The application of oil on strip is a challenge for most producers. Uneven and over-application of oil are typical when using wringer rolls or open pipes. Misting, low transfer efficiency and a hazardous work environment are common problems when applying oil with costly-to-operate air atomizing spray systems. Our new AccuOil system solves all these problems through precision application. Waste, inconsistency and the need for compressed air are eliminated.

The AccuOil system uses Precision Spray Control (PSC) to ensure the proper volume of oil is applied consistently, even when line speed changes and sheet width varies. Electrically-actuated, hydraulic PulsaJet® spray nozzles mounted on spray headers provide uniform, consistent application of the oil. System control is provided by a PLC equipped with AutoJet® PSC drivers.

The AccuOil system easily accommodates different strip widths. Only the nozzles required to cover the width of the strip are activated to spray, eliminating waste. See example at the top of the page.

Benefits

▪ Reduce scrap - uniform coverage across the entire strip

▪ Consistent application - even when line speed changes

▪ Lower operating costs - reduce oil consumption through precision application; no compressed air required

▪ Reduce maintenance time - no misting or overspray improves worker safety and minimizes clean-up time and oil removal costs
