Delevan introduces Cool-Cast nozzle assemblies

The Cool-Cast nozzle range improves cooling performance on continuous casting lines.
The Cool-Cast nozzle assemblies provide an even spray-distribution for effective quenching and higher quality yield.
The robust nozzles use a block-body configuration and a precisely aligned spray tip to create and maintain the ideal nozzle alignment, despite harsh steel industry site conditions.
Steve Swoope from Delavan said: 'Steel makers need production continuity, the elimination of break outs and outages for plant servicing.
'They also need to maximise the premium product yield by eradicating scrap and sub-standard output.
'Improving the effectiveness of the secondary cooling addresses these requirements.' The two-fluid design Cool-Cast nozzle uses air and water.
The desired spray pattern is maintained at different flow rates by varying air pressure to give a good turn down ratio for the production of different grades of steel.
The block-design nozzle assembly permits parallel inlet connections and allows simple and accurate installation.
Blocks can be securely fixed, ensuring nozzles remain at optimum spacing and alignment to guarantee consistent cooling performance.
The need for engineering maintenance on the cooling system is minimised by this reliable design.
The advanced block design assembly achieves flow rates with lower air consumption, saving energy by reducing loading on air compressors.
Cool-Cast nozzles are manufactured in stainless steel for extended service life.
In the event of an internal blockage, the Cool-Cast block-design nozzle has a removable liquid metering unit which can be taken from the assembly without disconnecting the nozzle from the header.
Likewise, nozzle tips can be replaced individually in a matter of minutes.
Mating lugs on the nozzle tip and lance ensure perfect alignment without the need for individual adjustment or use of a sealing medium.
Maintenance requirements are therefore greatly simplified.
Steel producers in the US using the Delavan Cool-Cast system include Nucor Steel in Arkansas, Ipsco in Mobile and Arcelormittal Riverdale in Cleveland.
