Abstract (en)

The pneumatic stabiliser, designed to deliver a gas such as air, nitrogen or carbon dioxide under pressure to at least one side of a continuously-running metal strip (1), especially a steel strip leaving a hot galvanising bath of molten zinc (2), consists of a housing (5) with at least two tranverse gas outlet slits (6) covering the width of the strip with the space between the slits covered by a perforated plate (8). The plate covers a housing cavity (7) with side walls (17) and a back (27), containing a moving plate (9) connected to a passive damper (10) essentially in the form of a damped harmonic oscillater. The gas flows from the slits can be delivered perpendicular or at an oblique angle to the moving strip's surface.
