Definitions
- the invention relates to a method and a system for hot dip galvanizing hot-rolled steel strip, the strip being in a first process step introduced into a pickling station and therein a layer of scale and reaction products be removed from the belt surface.
- the belt is inserted into a rinsing station and the Belt surface washed away from residues of the pickling and pickling products, and then inserted into a drying station and dried in it.
- the hot-dip coating in particular the hot-dip galvanizing of hot-rolled steel strip, so-called hot strip, is becoming more and more important economically compared to conventional cold-rolled strip coating.
- hot strip Through the development of thin slab technology in hot strip, there is the technical possibility of producing hot strips in the thickness range below 1.2 mm from the casting heat. There is also the possibility, depending on customer requirements, to replace cold strip with comparatively cheaper hot strip.
- the actual coating process is an annealing furnace upstream, in which at high temperatures a structural transformation to achieve the desired mechanical properties.
- the existing one Temperature difference between molten bath, preferably zinc or Zinc alloys, and the maximum strip temperature can be up to 400 ° C. With this tape overheating, however, a fire coating is not feasible, which is why the tape cools down before coating Temperatures close to the melting bath temperature must be made.
- Hot strip or pre-annealed cold strip do not require annealing in order to influence the mechanical properties, rather the Band temperature only adjusted to that of the melt pool to the desired Reaction of the steel strip surface with the alloy components to reach the weld pool. In contrast is a high temperature annealing often even disadvantageous for the mechanical properties of the belt.
- the present invention relates exclusively to the process variants for hot strip hot finishing or hot strip hot galvanizing.
- the desired temperature level lies with previously operated systems for fire coating still higher than the required 450 ° C of the zinc bath. reason for that is the required removal of all oxidation products and their precursors the steel strip surface. Oxidation products inevitably arise in the transition area from the pickling stage via the rinsing and drying stage into the oven entrance by exposure to atmospheric oxygen. The amount and training of in Oxidation products entering the furnace and those brought in from the belt Atmospheric oxygen determine the necessary process parameters of the treatment procedure, characterized by a required reduction potential, Temperature level and holding time. The temperature level used is often high so high that the strip is additionally cooled before entering the zinc bath must become.
- Document WO 83/00885 discloses a metal band, of which the iron oxides were removed by reduction in a protective gas atmosphere, and its Temperature brought a little higher than the melting temperature of the zinc bath with the metal strip immersed in the conventional zinc bath becomes.
- the bath contains mixed metal in a ratio between 0.01% and 0.5 % preferably between 0.02% and 0.08%.
- the object of the invention based on specifying a method and a hot strip galvanizing plant, which overcomes the aforementioned disadvantages and difficulties and hot-dip galvanized with an economical outlay on material and operating costs Steel strip delivers high and flawless surface quality.
- a corresponding plant for performing the method according to the invention accordingly provides that the outlet of the last rinsing stage of the rinsing station with the inlet of the dryer and its outlet with the inlet of the Furnace connected by locks and facing the surrounding Atmosphere are hermetically sealed.
- the above-mentioned measures preserve the optimal strip condition after pickling into the oven and achieve an optimal setting of the strip temperature when immersed in the zinc bath.
- the access of oxygen and the associated surface reactions, especially oxidation, are prevented.
- This enables furnace operation at temperatures in the range of the melt bath temperature. Overheating of the belt and an extension of the holding time in the oven are not necessary. A belt cooler becomes superfluous.
- the procedure according to the invention and the corresponding system allow a much more compact design of the furnace element and lower investment and operating costs.
- furnace operation with lower H 2 contents in the protective gas is possible.
- the disadvantages in the aforementioned conventional method with an increased zinc bath temperature are advantageously avoided.
- the strip is namely set to a temperature which is at most 50 ° K higher than the immersion temperature in the zinc bath.
- a strip 50 is transferred to a pickling station 10 introduced with three pickling stages 11 to 13 and in it a scale layer as well as reaction products removed from the belt surface.
- a pickling station 10 usually pickling in the pickling station 10 or in the pickling stages 11, 12, 13 using hydrochloric acid (HCL).
- HCL hydrochloric acid
- the belt 50 is brought into the rinsing station 20 the rinse stages 21 to 23 introduced and therein the belt surface of residues the stain and the stain products exempt. Then the tape is in the drying station 30 inserted and dried therein. From there the tape 50 in a further method step into an oven 40, comprising a preheating stage 41 and an integrated temperature control stage 42, introduced and therein preferably heated to a tempering temperature in a protective gas atmosphere, and passed through a galvanizing bath in a last process step. The surface of the strip 50 is coated with a hot-dip galvanizing layer overdrawn.
- a water-repellent or binding medium 25 is introduced into the rinsing stage 23.
- NH 3 or a solution of NH 3 can be used as the medium.
- a preferred embodiment of the method provides that the belt 50 is rinsed in the rinsing station 20 in the first stages 21, 22 with deionized water and in the third stage 23 with or with the addition of NH 3 as the drying medium.
- the measures according to the invention maintain the optimum strip state after pickling into the tempering furnace because the introduction of atmospheric oxygen is prevented.
- its design can be simplified due to the lower heating power required and the cooling section eliminated and can be realized with more favorable investment and operating costs. Oven operation is also possible with comparatively low H 2 contents in the protective gas.
Description
Durch Entwicklung der Dünnbrammentechnologie bei Warmband besteht die technische Möglichkeit, Warmbänder im Dickenbereich unter 1,2 mm aus der Gießhitze zu erzeugen. Es besteht damit ferner die Möglichkeit, Kaltband in Abhängigkeit der Kundenanforderungen durch vergleichsweise preisgünstigeres Warmband zu substituieren.
- Vorheizen bis zu einer Temperatur, die geeignet ist zum Erreichen erwünschter mechanischer Eigenschaften des Bandes. Die Vorheiztemperatur wird zwischen 400° C und 950° C eingestellt. Abschrecken des Bandes in einem wässrigen Bad bei dessen Siedetemperatur. Herausnehmen des Bandes aus dem Bad. Dabei soll eine Oxydschicht von weniger als 2 g/m2 ausgebildet sein. Eliminieren der Oxydschicht von wenigstens einem Oberflächenbereich des Bandes und Einstellen der Temperatur im Bereich von 420° und 550° C und Aufrechterhalten dieser Temperatur.
Dies wird erreicht durch:
- direkte Kopplung zumindest der letzten Spülstufe der Spülstation über die Trocknungsstufe mit dem Ofeneingang unter Abschirmung von Luftsauerstoff,
- Auftragen eines wasserbindenden Mediums, bevorzugt NH3, oder einer Lösung davon, auf das Band in der Spülstufe, wonach sich in der anschließenden Trocknungsstufe das wasserbindende Medium schnell und rückstandsfrei, das heißt ohne Eintrag von Sauerstoff oder flüssiges Reinigungsmedium vom Band entfernen lässt,
- alternativ durch einen Betrieb der Trockenstufe mit einer reduzierend wirkenden Atmosphäre, zum Beispiel N2/H2-Gasgemisch.
Erfindungsgemäß wird nämlich das Band auf eine Temperatur eingestellt, die maximal 50 °K höher liegt, als die Eintauchtemperatur in das Zinkbad.
