From the viewpoint of energy conservation, typical cooling methods such as air-atomized mist cooling or forced air cooling, which use a large amount of compressed air, are required to reduce the power. Super heated water, when it is injected under atmospheric pressure from the nozzle, makes quite uniform mist jet by sudden boiling, and can easily be made from low-grade waste heat in the steel manufacture. This study, using superheated water jet as a cooling device, experimentally determined its cooling properties and compared them with those of the air-atomized mist jet cooling.
