Definitions

  • the present invention relates to a hot dipping coating plant and continuously a metal strip, including a steel strip.
  • steel sheets coated with a protective layer for example against corrosion and usually coated with a zinc layer are used.
  • This type of sheet is used in various industries to make all kinds of parts including appearance parts.
  • an Fe-Zn-Al intermetallic alloy is formed on the surface of said strip with a thickness of some ten nanometers.
  • the corrosion resistance of the parts thus coated is ensured by the zinc, the thickness of which is most often produced by pneumatic wringing.
  • the adhesion of the zinc on the metal strip is provided by the intermetallic alloy layer mentioned above.
  • this steel strip Before the passage of the steel strip in the bath of molten metal, this steel strip first circulates in a annealing furnace under a reducing atmosphere in order to recrystallize it after the important work hardening related to the rolling operation. cold, and prepare its chemical surface state to promote the chemical reactions necessary for the actual quenching operation.
  • the steel strip is brought to about 650 to 900 ° C depending on the grade for the time required for recrystallization and surface preparation. It is then cooled to a temperature close to that of the molten metal bath using exchangers.
  • the steel strip After passing through the annealing furnace, the steel strip passes through a sheath also called “bell drop” or “horn” under a protective atmosphere with respect to the steel and is immersed in the bath of molten metal.
  • a sheath also called "bell drop” or “horn” under a protective atmosphere with respect to the steel and is immersed in the bath of molten metal.
  • the lower end of the sheath is immersed in the metal bath to determine, with the surface of said bath and inside this sheath, a liquid seal which is traversed by the steel strip during its scrolling in said sheath.
  • the steel strip is deflected by a roll immersed in the metal bath and it emerges from the metal bath, then passes through the wiper means for regulating the thickness of the liquid metal coating on the steel strip.
  • the surface of the liquid gasket inside the sheath is generally covered with zinc oxide, resulting from the reaction between the atmosphere inside this sheath and the zinc liquid seal and intermetallic or solid matte compounds from the dissolution reaction of the steel strip.
  • These mattes or other particles, supersaturation in the zinc bath have a lower density than liquid zinc and go back to the surface of the bath and in particular to the surface of the liquid seal.
  • the coated steel strip has appearance defects which are amplified or even revealed during the zinc wringing operation.
  • the intruded particles are retained by the pneumatic wringing jets before being ejected or disintegrated, thus creating sub-thick streaks in the liquid zinc of a length of a few millimeters to a few centimeters.
  • a first solution to avoid these disadvantages consists in cleaning the surface of the liquid seal by pumping zinc oxides and mattes from the bath.
  • a second solution is to reduce the surface of the liquid seal at the point of passage of the steel strip by placing a plate of sheet metal or ceramic at this liquid seal to keep away from the band a portion of the particles present on the surface and get a self-cleaning of the liquid seal by this tape.
  • This arrangement does not allow to remove all the particles present on the surface of the liquid seal and the self-cleaning is all the more important that the surface of the liquid seal is reduced, which is incompatible with the industrial conditions of exploitation.
  • Another solution is to add a frame to the surface of the liquid seal in the sheath and surrounding the steel strip.
  • This arrangement does not completely eliminate the defects related to the entrainment of zinc oxides and mattes by the scrolling of the steel strip.
  • the zinc vapors at the liquid seal will condense on the walls of the frame and the slightest swirl caused by the vibrations or the thermal folds of the strip to immersion, the walls of the frame will become dirty and thus become areas for storing foreign bodies.
  • This solution can only work a few hours or even a day before becoming an additional source of defects.
  • this solution only partially processes the liquid seal and does not achieve a very low density of defects satisfying the requirements of customers wanting surfaces without appearance defects.
  • Renewal is achieved by introducing liquid zinc pumped into the bath in the vicinity of the immersion zone of the steel strip.
  • the piping ensuring the renewal of liquid zinc can cause scratches on the steel strip before immersion and is itself a source of defects by accumulation of condensed zinc vapor above the liquid seal.
  • a process is also known which is based on the renewal of zinc at the liquid seal and wherein this renewal is carried out using a stainless steel box surrounding the steel strip and opening on the surface of the liquid seal .
  • a pump sucks the particles entrained by the spill thus created and pushes them back into the volume of the bath.
  • This process also requires a very high pumping rate to maintain a permanent spill effect in that the box surrounding the strip in the bath volume above the bottom roller can not be hermetically sealed.
  • the object of the invention is to propose a continuous galvanizing installation of a metal strip which makes it possible to avoid the drawbacks previously mentioned and achieve the very low density of defects satisfying the requirements of customers desiring surfaces without appearance defects.
  • the subject of the invention is a continuous dipping coating installation of a metal strip according to claim 1.
  • the steel strip 1 passes into an annealing furnace, not shown, under a reducing atmosphere in order to recrystallize it after the cold-rolling-forming process, and prepare its chemical surface state to promote the chemical reactions necessary for the galvanizing operation.
  • the steel strip is brought to a temperature for example between 650 and 900 ° C.

  • the lower end of the sheath 13a is immersed in the zinc bath 12 so as to determine with the surface of said bath 12 and inside this sheath 13, a liquid seal 14.
  • the steel strip 1 is deflected by a roller 15 commonly called a bottom roller and placed in the zinc bath 12. At the outlet of this zinc bath 12, the coated steel strip 1 passes into spinning means 16 which are for example constituted by air jet nozzles 16a and which are directed towards each side of the steel strip 1 to regulate the thickness of the liquid zinc coating.

  • the upper edge 22a of the inner wall 22 is positioned above the surface of the liquid seal 14.
  • this compartment 23 serves as a receptacle for the zinc oxides that can come from the inclined bottom wall of the sheath and makes it possible to store these oxides in order to protect the steel strip 1.
  • the upper edge 22a of the inner wall 22 may be positioned below the surface of the liquid seal 14 and, in this case, the compartment 23 is a liquid zinc spill compartment, such as the compartment 21.

  • the line of passage of the steel strip 1 between the walls 20 and 22 of the two compartments 21 and 23 is determined by the diameter of the deflector roll 15 and by its position.
  • the sheath 13 comprises two parts, a fixed upper part 30 and a movable lower part 31, interconnected by a deformable element 32 so as to be able to modify the position of the movable lower part 31 of the sheath 13.
