Description	Spray cooling is a common technique used in continuous casting and other metallurgical processes where controlled temperature regimes are required. Cooling intensity is primarily affected by spray parameters such as pressure and coolant impingement density. Although not well known, thin layers of oxides can significantly modify the cooling intensity. This effect is dominant in the cooling of steel surfaces at high surface temperatures. Experimental investigation comparing the cooling of scale-free surfaces and oxidized surfaces show a difference of 50-80% in the cooling intensity. Even a scale layer of several microns can significantly modify the cooling intensity. It is not obvious but the scale layer can, in some specific cases, increase the cooling intensity. A low thermal conductivity of the oxides makes the cooling more intensive. The paper provides experimental evidence of this fact and details the mechanism of spray cooling with boiling.
