There is provided a cleaning apparatus for a surface of a sheet steel capable of satisfactorily removing scale from a surface of a sheet steel before, for example, hot rolling. Waters (42a, 46a) are ejected from nozzles (42, 46), with an ejection pressure of 100kg/cm2, a flow rate of 60 liters/minute and an ejection angle of 20 ° with respect to normal of the surface (32a) of the sheet steel, toward a downward-stream end with respect to a carrying direction. On the other hand, waters (44a, 48a) are ejected also from nozzles (44, 48), with the same ejection pressure, flow rate and ejection angle as those of the nozzles (42, 46), but different in the ejecting direction. That is, waters (44a, 48a) are ejected toward an upward-stream end with respect to the carrying direction. In other words, waters (42a, 44a, 46a, 48a) are ejected from the nozzles (42, 44, 46, 48) alternately in opposite directions as to an upward-stream end with respect to said carrying direction and a downward-stream end with respect to said carrying direction.
Dispositif de nettoyage de la surface de plaques d'acier assurant par exemple une élimination suffisante des dépôts pour en permettre le laminage à chaud. Des buses (42, 46) d'un nettoyeur (40) projettent de l'eau du côté aval du sens de transport selon un angle de 20 DEG par rapport à la normale à la surface (32a) de la plaque d'acier, à une pression de pulvérisation de 100 kg/cm<2> et à un débit de 60 l/min. Par ailleurs, de l'eau (44a, 48a) à pression et débit identiques et selon le même angle, est également projetée par des buses (44, 48), mais vers l'amont du sens de transport. En d'autres termes, l'eau (42a, 44a, 46a, 48a) est projetée en alternance par les buses correspondantes (42, 44, 46, 48) vers l'amont et l'aval de la direction de transport.
