Cooling Systems for Metallic Coating Lines

Spooner’s range of specialised, high-performance air coolers are ideally suited to the unique and demanding requirements of Metallic Coating lines post pot cooling. Spooner designs include low disturbance pre-freeze line coolers, Stabilising Coolers combining extremely high cooling rates with strip stabilising features and the important low maintenance cooler. Adding a Spooner Air Cooler to your new or existing galvanising line will reduce vibration, improve cooling rates, increase throughput and deliver savings on zinc/aluminium.

Applications

It's our features that make our coolers so good

We continually develop our features to ensure they provide the best results – here are some of those features……..

Spooner have taken our industry leading flotation technology and adapted it to provide unrivalled performance for post pot cooling on Continuous Metallic Coating lines:
Air pressure pad imparting a gentle ‘clamping’ force on strip to reduce vibration, offering the following benefits:

Improved strip stability
Improved coat weight control.
Improved surface appearance.
Lower strip tensions in tower particularly for thinner strips.

High heat transfer rate by using:

Controlled higher air velocities and higher air volumes without strip vibration.
Closer nozzle-to-strip operating distance without the risk of scratching.
Remotely adjustable nozzle to nozzle gaps allowing it the flexibly handle any strip conditions.

Advantages:

Lower tower height and/or increased throughput.
Reduced zinc/aluminium consumption.
Improved product quality.
Reduced wear on zinc pot roll bearings saving cost and downtime.
Potential to improve performance of existing Air Cooler which no longer need to be restricted to prevent strip vibration.

Designed to work below the freeze-line before the metallic coating is set. For best results use in conjunction with the Spooner Stabiliser Air Cooler. Features :

- Low vibration & disturbance design.
- Slot nozzles.
- Split into sections allowing 2 or 3 air separate velocity zones in each cooler.
- Finger feed nozzles giving gaps in pressure chambers which allows easy inspection of strip to assess surface quality and increased return air space for low vibration characteristics.

This is Spooners work horse cooler designed for economic, high performance and low maintenance operation. Normally found after a Stabilising cooler on the up leg or on horizontal / down legs of the cooling tower.

Features:

Arrays of holes, staggered pattern and optimized for nozzle-to-strip distance.
Very robust, nozzles don’t block and are easy clean.
High heat transfer rates.
Long term consistent performance.
Low maintenance requirements.

Spooner has considerable experience of using Air turns, flotation device for non-contact turning of Strip, in Paper, Converting and Aluminium Industries. We’ve now developed this technology to work with Steel strip opening new worlds for line configurations and eliminating the need for ever increasing Cooling Tower heights.

Features :

Based on proven technology.
Non-Contact Turning & high performance cooling combined.
Non-contact for improved surface quality and elimination of zinc pick-up.
Allows alternative building layouts.
Option for double sided cooling.
Radius circa 3 to 5 m.
Potential for use in St. Bright Anneal furnaces.

Designed to maintain strip temperature after induction furnace in Post Pot cooling tower, prior to air cooling furnace:

Features:

Heating Electric resistance elements or gas heated.
Multiple zones for line speed variations.

Three main Configurations:

Standard fixed unit.
Standard unit with Bookwise opening to allow. ambient cooling of strip when not required.
Combined HRZ / air coolers to maximize line flexibility. With heat retention, forced cooling and ambient cooling modes.
