The continuous casting of metals is a relatively new process in the steel industry, but tremendous strides in development have been made in recent years. In the constant pursuit of technological advancements, Delavan’s engineering staff have worked with steel mills world-wide to implement many improvements in the casting process. The result of much research and development is the Delavan Cool-Cast nozzle, which with its tightly uniform droplet size can significantly improve slab quality and reduce energy costs in your continuous casting operation. The cooling process is more controllable, with reduced tendency for water puddling and localized uneven cooling or thermally induced roller deflection. The flat spray pattern is thick, even over angles from 60° to 120°, offering good coverage with few nozzles.
- Patented nozzle design which
produces highly uniform
droplets with constant surface
area per given spray volume
- More controllable and even
- Reduced air consumption,
saving energy through reduced
air compressor load
- Wide passages prevent plugging
- Maximum heat transfer
- Large turn-down ratio
- Constant spray angle over
wide pressure range
Producing steel in today’s market from slabs to bar mills including secondary cooling during the casting process requires efficient spray nozzles. Delavan’s newest ‘Block Style’ Cool-Cast nozzle offers flexibility in alignment for tight space in-between the framed segments. The ability to use quick connect couplings with the parallel piping gives operators access to quick release nozzles during rebuilds. With interchangeable components, liquid and air can be easily adjusted to meet product changes for various grades of products. The all stainless steel construction extends the durability and life of the nozzle in harsh environments. Typically Cool-Cast nozzles produce results using less air than other types, further reducing cost of ownership. The ‘Block Style’ Cool-Cast nozzle has different thread sizes and liquid connections to avoid misalignment.
Block Design Features
- Inlet connections are parallel; there are no elbows required for product installation
- Easier maintenance; nozzles always go back into original installation, no re-alignment is necessary
- Fluid orifice can be removed and cleaned/replaced without removing nozzle assembly
- More robust with less joints
- Easier installation
- Patented fluid inlet can permit larger orifice sizes for equivalent flow rates
The original round design of the Cool-Cast nozzle has a lower initial capital cost than the block design, yet still provides the same outstanding spray cooling performance and operational characteristics of the Block version.
