Definitions
- the invention relates to continuous heat treatment lines of metal strips such as annealing lines or metal or organic coating.
- the cooling of the strips is achieved, according to the state of the art, with cooling chambers by blowing a gas, for example a mixture of nitrogen and hydrogen, in a closed chamber of cooling an annealing line or a galvanizing line upstream of the zinc pot, or by blowing air for example into a cooling tower after galvanizing.
- a gas for example a mixture of nitrogen and hydrogen
- the phenomenon of instability of the band in the cooling zones is known and is manifested for example by a torsional shift of the band about its longitudinal axis to a stable position or alternately in the form of oscillations of torsion.
- the formation of folds is caused by a discontinuity of slope in the cooling curve which generates a compressive stress in the strip.
- a crease on the web surface is produced if the compression stress caused by the discontinuity of cooling is greater than a limit value.
- the invention relates to a method and a device for controlling the position of the strip in a cooling zone in air or in an atmosphere, for example reducing, in order to prevent it from touching the walls of the equipment. the cooling zone and this by doing follow the band a theoretical cooling curve corresponding to a targeted thermal objective while reducing the risk of wrinkling.
- the cooling of a strip is generally carried out by air blast chambers, or reducing atmosphere, through holes or slots fed under pressure by an independent recirculation fan or a fan common to several boxes.
