Air mist nozzles
With the BilletCooler series, Lechler offers the world's first air mist nozzle for secondary cooling with a defined full cone. The Lechler BilletCooler Oval is the first air mist nozzle for secondary cooling with which a spray depth of up to 60° is possible with a non-clogging single slot orifice.
This enables larger surface areas between the support rollers to be cooled more evenly. This in turn reduces the risk of strand cracking.
Air mist nozzles of the BilletCooler series should be used wherever the control range of single-fluid nozzles is no longer sufficient for the wide range of steel products in billet- or bloom casters, or when the nozzle's flow rate falls to well below 2 l/min.
Standard programs with a full cone spray pattern and with an oval spray pattern with like-wise standardised flow rate, spray angle and spray depth graduations are available.
Defined spray patterns, high turn down ratios (min. to max. flow rate) and very large free cross sections (not liable to clogging) are the stand-out features of Billetcoolers.
Product informations
MasterCooler SMART® air mist nozzles are designed in line with the requirements of the secondary cooling system of each individual slab caster.
The water flow rate, the spray angle, the liquid distribution, the turn down ratio, the pipe length, the pipe shape and the type of connection are all adapted here.
To date, more than 100 slab strands have been successfully fitted with Mastercooler SMART air mist nozzles.
