Influence of the oxide layer on the spray cooling intensity

Popis výsledku v původním jazyce

Formation of oxide layers on the surface is inherent part of the steel production. The oxide layer primarily affects the surface quality and material losses during the steel processing. The influence of the oxide layer on the cooling intensity is not frequently reported but even thin layers of oxides can significantly modify the cooling intensity. The oxide layer factor is not as important as the water flow rate but it should be also considered for optimal regulation of the cooling process. The influence of the oxide layer on the heat transfer coefficient and Leidenfrost temperature is investigated in this paper. Laboratory measurement compares the spray cooling of oxide-free steel surface and oxidized steel surface. It shows significant change of the Leidenfrost temperature and heat transfer coefficient due to the oxide layer.
