With the first Billetcooler generation in 2002 the success story in secondary cooling for continuous casters started. Since then, we have equipped more billet and bloom casters with air mist nozzles than any other supplier.
And the development work continues. Because new requirements demand new cooling technologies.
Billetcooler FLEX solves your challenges:
The new Billetcooler FLEX nozzle is characterized by its constant spray angle over the entire turn-down range. We offer three different nozzle sizes, each with a turn-down ratio (min./max. water flow rate) of 1:10.
Lechler therefore covers the requirements of most bloom and billet casters with just three standard nozzles. This minimizes the number of different nozzles, reduces logistics costs and helps to avoid maintenance mistakes.
Controlled cooling. Thanks to the stable spray angle of between 60° and 70°, Billetcooler FLEX permits exact control of the cooling performance over the entire turn-down range for the first time.Thus, no overcooling or undercooling of the strand.
Flexible cooling. Billetcooler FLEX allows optimum adjustment of the water distribution for different formats – without time and cost-intensive nozzle replacement. This ensures an always optimum cooling.
Robust and maintenance-friendly. The very large free cross-sections for air and water avoid blockages and guarantee high system availability while offering a high operating reliability.
Energy-efficient. Thanks to the new nozzle design, the Billetcooler FLEX consumes less compressed air compared to conventional air mist nozzles. This helps to improve the energy efficiency of the overall installation and saves operating costs.
Low noise emissions. Compared with conventional nozzles for secondary cooling, Billetcooler FLEX reduces noise emissions by up to 15 dB and offers therefore an improved occupational safety.
Space and weight-saving. Thanks to the new design, the forged nozzle body of the Billetcooler FLEX requires less space and can also be used in cramped environments. A maintenance-friendly design.
