Important design parameters and user friendly features of modern air mist nozzles for slab and beam blank casters.
The demand for improved product quality and increased productivity has focussed attention on the need for more efficient systems of spray nozzle systems for secondary cooling. Nozzle characteristics msut be investigated and test procedures developed to mesure cooling patterns and heat transfer. Improved nozzle design and air/water systems gives in better water distribution and this reduces surface defects, corner cracking and core segregation. There are also important operational benefits which enable expansion in the product mix production capacity.
