Definitions

  • the present invention relates to a method of producing an installation for coating a scrolling product according to the preamble of claim 1.
  • an installation for coating a product running under a so-called longitudinal direction comprises a coating pot, comprising a coating agent such as a liquid metal (zinc or various alloys), into which the product is immersed in order to emerge from said pot coated with said agent.
  • a coating pot is generally placed in an enclosure at least partially or even completely buried relative to the ground level.
  • the coating installation is stopped.
  • the pot is emptied, dismantled then evacuated from the enclosure and finally it is replaced by another pot ready for use, to be filled with coating agent.
  • Such production stoppages of at least one to several days are very costly for the owner of the installation.
  • An object of the present invention is to propose making or adapting an installation comprising a first pot for coating a product with longitudinal travel, said first pot being disposed in a first enclosure, and the production or adaptation of which guarantees a stop of minimum or even zero production duration. Also, this realization or adaptation should allow secure maintenance of the pot with regard to deformation or crack factors. Finally, the said pot maintenance should be carried out for a minimum duration so as not to reduce the productivity of the installation.
  • a set of subclaims also has advantages of the invention.
  • an initially mono-pot installation installation configuration is presented for coating a moving product (pr_ON) along a longitudinal plane (X, Z) such as a flat and long product (strip or sequence of strips).
  • This product is dipped inclined at the top into the first pot (p1) containing a liquid metal such as zinc or various alloys.
  • the product After being deflected by a bottom roller (rf) placed in the jar, the product thus scrolls through the jar and emerges vertically from the jar.
  • the pot is placed in an enclosure (e1) which laterally surrounds the pot at least partially or otherwise its perimeter, for example semi-buried or completely buried (pit). More generally, this type of enclosure is therefore provided in an airspace and / or at least partially in the form of pits. Feet (pf) or another bottom support can then be provided to hold it stably in the bottom of the enclosure.
  • the orthogonal axes (X, Y, Z) are shown in Figures 1A and 1B .
  • the axes (X, Y) being horizontal and (Z) vertical.
  • the enclosures targeted by the invention are provided in an air space and / or at least partially in the form of simple pits, so that they are partially or completely underground relative to the ground (so). They are of course open at the top to allow a pot to be placed there, then they can be covered during the functional coating mode.
  • the first stage of creation ( fig. 1A, 1B ) of the second enclosure provides that it takes place while the product is in continuous scrolling (pr_ON) in the first pot (p1) and therefore the production is thus kept active during said first step.
  • Protective means between the two enclosures (e1, e2) are provided to prevent any pollution of the first pot (p1) by projections coming from the area of production of the second enclosure.
  • Means for creating the second enclosure (resumption or demolition of existing slabs, excavations, driving in pillars, etc.) are provided to be anti-vibration at the level of the first enclosure (for example by using diamond disc cutouts) of so that the quality of the coating in progress in the first enclosure is not negatively impacted.
  • a second coating pot (p2) in the second enclosure can thus start while the product is still in continuous scrolling (pr_ON) in the first pot (p1) and therefore the production is thus kept active during said second step. It is also planned to make the second pot (p2, fig. 2B ) advantageously mobile, in particular along the first axis (x) respectively.
  • the third stage of creation ( fig. 3A, 3B ) a third enclosure (e3) encompassing at least the first enclosure (e1) and here the second enclosure (e2) along the axis (X) is thus produced while the product is still in continuous movement (pr_ON) in the first pot (p1) and therefore production is thus kept active during said third stage.
  • first, second and third stages according to the method of carrying out the installation can very advantageously take place while the product is in continuous movement (pr_ON), that is to say free of all stopping production of the scrolling product during coating.
  • Figures 4A, 4B , 5A, 5B have top (type A) and side (type B) views of the first installation during steps to replace the first pot (p1) with the second pot (p2).
  • This step of replacing a pot requires a scrolling stop (pr_OFF) of the product in the second pot, in order to be able to empty it and extract it from the third enclosure (e3).
  • the second movable pot is moved horizontally and mono-directionally to the location of the old first pot, for example by a simple system of rectilinear rails placed in the bottom of the enclosure.
  • the Figures 5A and 5B then have a reset depending on the scrolling of the product (pr_ON) in the second pot (p2), the initial location of the second pot ( fig. 4A, 4B ) remaining vacant.
  • this vacant location makes it possible to install a new, third mobile pot (p3) there, such as the Figures 6A, 6B present it in top view (type A) and side view (type B) of the first installation, then again in twin-pot form. It is thus possible to predict the future (third) replacement pot for the second pot (p2) in advance of the maintenance phase of said second pot. It should also be noted that this pre-production of the third pot takes place advantageously, while the product is in continuous movement (pr_ON), that is to say free from any production stop of the product in progress during coating. .
  • the method according to the invention then provides for generating a free space for a pot, as in Figures 1A, 1B .
  • first, second and third steps according to the so-called “extended” installation method can very advantageously take place while the product is in continuous scrolling (pr_ON) here in the first pot (pl '), that is to say free from any production stop of the scrolling product during coating.
  • the first and second coating pots (p1 ', p2') are also advantageously provided movable in the third enclosure (e3 '), in particular along a single axis respectively (X, see fig. 1A, 1B ), therefore in a mono-directional and horizontal way, making it possible to avoid deformations or cracks in the moving pots.
  • Figures 9A, 9B, 10A, 10B present top (type A) and side (type B) views of the so-called “extended” installation during steps to replace the first pot (p1 ') to be maintained with the second pot (p2') to be put in place production.
  • this step is the only one requiring a production stop of the scrolling product (pr_OFF) during coating.
  • This step has already been described analogously to Figures 4A, 4B , 5A, 5B (pots p1, p2). The only difference is that this so-called "extended” installation ultimately provides three pot locations and two movable pots.
  • the related advantage is that during maintenance of a first jar in continuous movement (pr_ON), the other second jar can be maintained and prepared in advance of said maintenance, without interfering with the production of the product. scrolling during coating in the first pot. This also applies vice versa for the first and second pots, because the pots are moved simultaneously in pairs from the left-center pot locations to the center-right pot locations ( fig. 9A, 9B, 10A, 10B ), and vice versa. The maintenance times for each of the pots are therefore here without influencing the productivity of the extended installation.
  • Figure 11 presents a side view (type B) of a so-called “very extensive” installation following steps of more extensive realization of the so-called “extended” installation of the figure 8B , 9B or 10B and finally comprising a final enclosure where are arranged at least the first pot, the second pot, a third pot added according to the method provided for the invention and two free locations for a pot, respectively created also according to the method provided for the invention .
  • this "tri-pot" installation configuration has the same advantages as the "bi-pot” configuration.
  • Figures 12A, 12B , 12C, 12D, 12E , 14F present views from above and from the side of an installation known as “orthogonally extended” following steps of more extensive realization of the installation of the figure 5A, 5B or 6A, 6B and finally comprising at least a first pot, a second pot according to the method provided for the invention and a free space for a pot.
  • the Figures 12E and 12F represent a change of the first pot (p1 ') with the second pot (p2') by brief stop of the product scrolling (pr_OFF), followed by a horizontal mono-directional movement of the first pot from its location under the product in stop scrolling (pr_OFF) to a first vacant location juxtaposed, then a mono-directional horizontal displacement of the second pot from a second vacant location to the location under the product to be scrolled (pr_ON).
  • configurations of said “third” enclosure are possible by arranging the locations of pots successively linear along an axis and / and orthogonal along two axes. perpendicular whose intersection is placed at the place of coating of product.
  • the first and second coating pots are provided movable, in particular along the first and second axes respectively (X, Y), these being aligned (or even parallel) or orthogonal.
  • the third enclosure is created in a design comprising at least two, ideally three or four or five, or more locations of coating pots.
  • one of the installations carried out by the method according to the invention comprising at least the first coating pot in functional mode of coating the product and the second pot in assembly mode, provides that said pots are arranged mobile in the third enclosure, in particular under horizontal mono-directional paths, aligned and / and perpendicular.
