Original abstract

Descaling of hot rolled plates is a typical application for high pressure flat jet nozzles. A row of nozzles with an overlapping area at a direction of a moving hot plate is usually used. Homogeneity of descaling is very important parameter for final quality of the rolled plate. This paper describes the measurements of impact footprint for a single nozzle as well as for two overlapping nozzles. Two different methods of measurements were used. The first method measures impact forces in free stream, the second one measures impact forces of water stream penetrating through a forming water layer on a test plate. Size of a pressure sensor also influences the measurement data.

Czech abstract

Odkujování za tepla válcovaných desek je typická aplikace použití vysokotlakých plochých trysek. Většinou se používá řada trysek, jejichž dopadové stopy se ve směru pohybující se odkujované desky vzájemně překrývají. Homogenita odkujení po šířce desky je velmi důležitý parametr pro výslednou kvalitu válcovaného materiálu. Příspěvek pojednává o měření, během kterého se zkoumaly dopadové stopy jak jednotlivých trysek, tak dvojice trysek, jejichž dopadové stopy se ve směru válcování překrývají. Pro měření byly použity dvě odlišné metody.
