Abstract

Ein Verfahren zum Behandeln der Oberflächen von metallischem Bandgut (1), insbesondere zum Beizen von Walzgut, sieht vor, das Bandgut (1) in einem Beizbecken (2) durch einen Behandlungskanal (3) zu transportieren und mit einem säurehaltigen Beizmedium (4) in Strahlen (5) zu besprühen.
Um auch schwer beizbare Bandgüten (Stahlgüten) schneller zu beizen, die mit einer relativ niedrigen Bandgut-Geschwindigkeiten gefahren werden, kann die notwendige Turbulenz dahingehend erhöht werden, dass innerhalb von Längsabschnitten (6) des Behandlungskanals (3) in zumindest über dem Bandgut (1) gebildeten, quer zur Bandtransportrichtung (7) verlaufenden Trennräumen (8) aus zumindest jeweils einem Düsenrohr (5a) das Beizmedium (4) quer zur Bandtransportrichtung (7) in einen Trennraum (8) eingespritzt wird.

A method for treating the surfaces of metallic strip material (1), in particular for pickling rolled material, provides for the strip material (1) to be transported in a pickling basin (2) through a treatment channel (3) and with an acidic pickling medium (4) Spray (5).
In order to pickle even difficult-to-grind strip grades (steel grades) that are run at a relatively low strip material speed, the necessary turbulence can be increased to the extent that within longitudinal sections (6) of the treatment channel (3) in at least above the strip material (1 ) formed, transverse to the tape transport direction (7) separating spaces (8) from at least one nozzle tube (5a), the pickling medium (4) is injected transversely to the tape transport direction (7) into a separation space (8).
