Influence of Parameters of Hydraulic Descaling on Temperature Losses and Surface Quality of Rolled Material

Popis výsledku v původním jazyce

Hydraulic descaling is a process of removing the oxide from the hot steel surface. Surface quality after descaling is fundamental for the final surface quality of a roll product. Aspect of heat extraction, as a part of descaling process, is not usually seriously considered. Surface sub-cooling can negatively influence the demanded temperature field in the rolled material. The main goal of the paper is to show how the setting of hydraulic descaling parameters can influence heat transfer and the final temperature field in the rolled material. Experimental work was concentrated on the study of descaling in relation to heat transfer and the quality of scale removing from the surface. Two types of measurements were implemented. The first one is a measurement of temperature drop when a product is passing under the nozzle (heat transfer test). The second type is a study of the surface quality where a defined layer of oxides is sprayed and its remaining thickness is evaluated. The heat transfe
