The design of cooling systems for running hot steel plates has received much attention because the mechanical and/or metallurgical properties of final products are greatly influenced by the cooling capacity of the system. Thus many steel makers have largely concentrated on simply increasing the cooling water supply capacity of the system. Some researchers believe that plate cooling is a type of thermal communication between the hot plate and the cooling water or the atmosphere, so they have emphasized the importance of thermal conditions such as the cooling water temperature or air humidity. Actually the cooling process is governed by the basic physics of boiling heat transfer between the hot steel plate and the cooling water. Therefore steel makers should be more concerned about the influence of the design parameters of cooling facilities on the boiling phenomenon rather than the simple increase of the cooling water flow rate. In this study, when the diameter of the nozzle supplying cooling water is changed, its effect on boiling heat transfer has been investigated numerically. The average heat flux, the Leidenfroststeam-layer thickness, the temperature drop and so on were investigated according to nozzle diameter.

“…While many researchers have used a heater in the specimen to obtain steady state data during the cooling process, they did not use a heater, and obtained the transient cooling data during the experiment. Figure 2 shows the experimental data presented in the paper by Xu et al, 10) and displays time variations of the heat fluxes at eight monitoring points. In the figure, the maximum heat flux at the stagnation point increases up to 12 MW/m 2 .…”

Intricate physical phenomena such as boiling heat transfer, free surface flow, and the moving of a cooling object (running hot plate) are included in the ROT (Run Out Table) cooling process of hot rolling. Mixed reciprocal actions are also included. Therefore, analyzing the process with considering all relevant phenomena simultaneously has been an important objective in this field for a long time. In the ROT process, cooling performance could be affected by the upstream process, and by various environmental factors such as refining, reheating, and the ambient temperature and humidity. In this study, with such disturbances numerically fixed, cooling capacities are compared by varying the arrangement of the cooling water supply nozzle. Generally, the cooling heat flux is known to vary in the plate running direction. Thus, clustering the nozzle in the upstream or downstream direction could affect the average cooling capacity of the facilities. The cooling histories, the heat fluxes on the plate surface, and the thickness of the Leidenfrost steam layer are compared for various nozzle arrangements.
