Abstract

Variation in strip velocity in a treatment section (2) of, e.g., a pickling installation is compensated by variation in strip length between the treatment section (2) outlet end and a downstream tensioner, so that constant strip length is maintained between the outlet end and an upstream tensioner (61) without perceptible variation in tractive force applied to the strip (4) between tensioners. A metallic strip (4) moves in a longitudinal direction through an installation comprising at least three successive sections, namely a feed section (1), a section (2) for treatment in at least one extended tank containing processing fluid and having an inlet (23) and an outlet located at an upper level and between which the moving band forms a curve (40) whose lower part (43) is located at a lower level that depends on the length of the strip between the inlet (23) and outlet, and a discharge section. The treatment section (2) is connected to an upstream tensioner (61) and a downstream tensioner located before the inlet end (20) and behind the outlet end of the treatment section (2), respectively. Any variation in strip velocity in the treatment section (2) is compensated immediately, at least during strip acceleration or deceleration, by a corresponding variation in the length of the strip between the outlet end of the treatment section (2) and the downstream tensioner, so as to maintain a substantially constant length of the strip between the outlet end of the treatment section (2) and the upstream tensioner (61) without any perceptible variation in the tractive force applied to the strip (4) between the two tensioners. An Independent claim is given for an installation for implementation of the invented process.
