Steel is the most fundamental material used everywhere. In steelmaking, precise control of steel temperature during spray cooling process has a great influence on the quality of the product. In order to obtain a desired material, it is necessary to accurately understand the effect of spray (water temperature and flowrate) and the surface conditions. In the previous work, focusing on the surface properties, we conducted spray cooling experiments on steel plates coated with each of five distinct oxide layers with different thickness. Furthermore, we observed the behavior of a single droplet impinging onto the surfaces with high speed camera, in order to capture the fundamental cooling process of in detail.
