- the metal strand 1 enters the system at a predetermined conveying speed v in the conveying direction R and is initially guided between two S-roll stands 5 and 6, which exert a tensile force F on the metal strand 1.
- a means 4 for straightening the metal strand 1 is arranged. This means 4 is a stretch bending straightening machine.
- the metal strand 1 in the stretch bending straightening machine 4 is bent or set by adjustable rollers under high tension by the tensile force F so that the metal strand 1 has a high degree of flatness after leaving the stretch bending straightening machine 4 Has.

- a test means 10 is arranged, which is able to inspect the surface of the metal strand 1 and pass the result of the test to a control means 11.
- the control means 11 acts on the drive of the overall device, not shown, in such a way that the conveying speed v of the metal strand 1 is influenced such that the result of the descaling or cleaning of a desired specification equivalent.
- the control means 11 can reduce the conveying speed v; As a result, the surface of the metal strand 1 is exposed to a longer exposure time of the plasma, which improves the Entzu matters- or cleaning result. However, if there is already an excessively large, unneeded quality, the control means 11 can provide an increase in the conveying speed v, so that although the quality of the descaling or cleaning is reduced, the productivity of the overall system is increased.

caractérisé par
des moyens (4) qui sont agencés en direction de convoyage (R) en amont du dispositif (2) de décalaminage au plasma et/ou de nettoyage au plasma et qui confèrent à la barre métallique (1) un haut degré de planéité, et en amont et/ou en aval du moyen (4) est agencé au moins un dispositif de serrage (5, 6) pour engendrer une force de traction (F) dans la barre métallique (1). - Dispositif selon la revendication 9,
caractérisé en ce que
le dispositif (2) de décalaminage au plasma et/ou de nettoyage au plasma présente une chambre de traitement (8) sous vide dans laquelle un nombre d'électrodes (9) de structure modulaire sont agencées en direction de convoyage (R) de la barre métallique (1). - Dispositif selon la revendication 10,
caractérisé en ce que
les électrodes (9) individuelles peuvent être mises en circuit et hors circuit indépendamment les unes des autres en fonction du degré de calaminage et/ou du degré d'encrassement de la surface de la barre métallique (1) ainsi qu'en fonction de la vitesse (v) avec laquelle la barre métallique (1) passe à travers le dispositif (2) de décalaminage au plasma et/ou de nettoyage au plasma. - Dispositif selon l'une des revendications 9 à 11,
en direction de convoyage (R) en aval du dispositif (2) de décalaminage au plasma et/ou de nettoyage au plasma sont agencés des moyens de contrôle (10) de la surface de la barre métallique (1), qui sont en liaison avec des moyens d'asservissement (11), les moyens d'asservissement (11) définissant la vitesse (v) avec laquelle la barre métallique (1) est guidée à travers le dispositif (2) de décalaminage au plasma et/ou de nettoyage au plasma en fonction du contrôle pour obtenir la qualité de décalaminage et/ou de nettoyage souhaitée. - Dispositif selon l'une des revendications 9 à 12,
caractérisé en ce que
en direction de convoyage (R) en aval du dispositif (2) de décalaminage au plasma et/ou de nettoyage au plasma sont agencés des moyens (12) pour revêtir la barre métallique (1) avec du métal liquide, en particulier par galvanisation à chaud. - Dispositif selon l'une des revendications 9 à 13,
caractérisé en ce que
en direction de convoyage (R) en aval du dispositif (2) de décalaminage au plasma et/ou de nettoyage au plasma sont agencés des moyens (15) pour laminer à froid la barre métallique (1).
