Definitions

  • the cooling phase of the steel strips is particularly critical. Indeed, it is the cooling phase which mainly conditions the final mechanical and metallurgical properties of the steel strip. Depending on the cooling rate of the steel strip and its chemical composition, different metallurgical phases can be created and thus lead to different mechanical properties of the steel strip.
  • a cooling section of a continuous line for annealing or galvanizing steel strips arranged to receive a metal strip, said section comprising at least one cooling zone dry arranged to project a gas onto said steel strip and at least one wet cooling zone arranged to project a liquid or a mixture of gas and liquid onto said steel strip.
  • the dry cooling zone can comprise blowing boxes arranged to project the gas onto the steel strip.
  • the gas can be a mixture of nitrogen and hydrogen.
  • the wet cooling zone can comprise nozzles arranged to project the liquid or the mixture of gas and liquid onto the steel strip.
  • the liquid can be water, an acid solution, or any other solution.
  • the cooling section according to the invention can make it possible to produce steels with high mechanical properties which can directly undergo a galvanizing step at the outlet of said section, without requiring intermediate chemical treatment.
  • the wet cooling zone makes it possible to reach cooling speeds of the order of 1000°C/s for a steel strip 1 mm thick.
  • the cooling section according to the invention also makes it possible to successively perform dry cooling and wet cooling without having to cut the strip to bypass one of the cooling zones.
  • the gain in productivity is therefore substantial.
  • the wet cooling zone and the dry cooling zone are arranged, respectively, along a first vertical direction and a second vertical direction parallel to the first direction.
  • the wet cooling zone can be arranged upstream, according to the direction of travel of the steel strip in the cooling section, or downstream of the dry cooling zone.
  • the wet cooling zone and the dry cooling zone are arranged in the same vertical direction.
  • a person skilled in the art usually designates this variant by qualifying it as a one-pass embodiment.
  • the dry cooling zone can be arranged below the wet cooling zone.
  • a system for drying the steel strip can be interposed between the wet cooling zone and the dry cooling zone.
  • the atmosphere separation airlock comprises three pairs of rollers or flaps, each of the pairs being arranged transversely to a running direction of the metal strip, said three pairs of rollers or flaps delimiting between them two zones of said airlock, respectively a first zone delimited by the first two pairs of rollers or flaps in the running direction of the strip and located on the side of the dry cooling zone comprising withdrawal means, and respectively a second zone, delimited by the last two pairs of rollers or shutters in the running direction of the strip and located on the side of the wet cooling zone and comprising means arranged to inject an inert gas.
  • a buffer zone is thus created between the first two pairs of rollers and an atmosphere extraction system between the last two pairs of rollers.
  • this airlock advantageously creates a "clean" zone in which it is possible to measure the temperature of the strip over its width, for example by means of a scanner, or occasionally, by means of for example a pyrometer. This temperature measurement can help to better regulate the strip cooling process.
  • a method for cooling a continuous line for annealing or galvanizing steel strips arranged to receive a metal strip comprising at least one dry cooling zone arranged to spraying a gas onto said steel strip, said method comprising at least one dry cooling step comprising spraying a gas onto the steel strip and at least one wet cooling step comprising spraying a liquid or a mixture of gas and liquid on the steel strip.
  • a cooling section according to the first embodiment, of a continuous line for annealing or galvanizing metal strips arranged to receive a metal strip 1 in a running direction S, successively combining, in the direction of scrolling, at least one zone 2 of dry cooling and one zone 5 of wet cooling.
  • the cooling section further comprises an airlock 4 for separating atmospheres separating the zone 2 of dry cooling and the zone 5 of wet cooling.
  • the wet cooling zone 5 comprises means for withdrawal 7 of vapors which, in the example shown in the figure, are arranged in the upper part of this zone 5 of wet cooling.
  • the airlock 4 for separating atmospheres disposed between the dry zone 2 and the wet zone 5 comprises three successive pairs 8, 9 and 10 of rollers, according to the running direction S of the metal strip 1. Each of the pairs is placed transversely to the running direction of the metal strip.
  • Nitrogen is injected into zone 12 by means of a supply 14 constituting a means arranged to inject an inert gas.
  • a draw-off is carried out in zone 11 by a draw-off means 15.
  • the pressure and the inert gas injection rate in zone 12 and the draw-off flow rate in zone 11 are fixed so that the flow of gas between the zones 11 and 12 or only from zone 12 to zone 11. This prevents the entry of humid atmosphere coming from the humid zone 5 into zone 11 of the airlock and any mixing of the latter with the dry atmosphere of the airlock. area 2.
  • the return tank 18 includes a second set 19 of gas knives intended to remove the liquid which could still be present on the metal strip 1.
  • the system of drying and purging of the cooling zone of the second embodiment comprises points 28 for injecting an inert gas, for example nitrogen, and vents 29 allow rapid purging of the wet cooling zone 5 .
  • the inert gas supplying the knives 27 and the injection points 28 is heated beforehand, for example to a temperature of about 50°C.
