Description
Die Erfindung betrifft ein Verfahren zur Entzunderung oder Reinigung von metallischen Oberflächen, u. a. von Bändern, bei dem ein Kryogen aufgebracht wird, um Zunder- oder Schmutzpartikel von deren metallischer Oberfläche zu entfernen. Des Weiteren betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The The invention relates to a process for descaling or purification of metallic surfaces, u. a. of ribbons, in which a cryogen is applied to scale or dirt particles to remove from their metallic surface. Furthermore The invention relates to a device for implementation of the procedure.
Zur Erzielung einer guten Oberflächenqualität, insbesondere bei der Herstellung metallischer Bänder, wird z. B. ein verzundertes Warmband mit einer heißen Säurelösung sehr stark benetzt um die Oxidschicht vollständig von der Bandoberfläche zu entfernen, bevor es der Weiterverarbeitung z. B. durch Kaltwalzen zugeführt wird. Um den Prozess des Beizens mittels heißer Säure positiv zu beeinflussen, wird vor dem Prozessbeginn die geschlossene Zunderoberfläche durch starkes Biegen um mehrere kleine Rollen quer zu eigentlichen Bandlaufrichtung, aufgebrochen, um den Säureangriff zu erleichtern. Positiver Nebeneffekt dabei ist, dass durch den zum Biegen um die Rollen notwendigen Bandzug während des Biegens das Band in der Weise gelängt wird, dass weitgehend alle Bandbreitenbereiche auf gleiche Länge gebracht werden und somit Planheitsfehler im Band beseitigt werden können. Der Gesamtprozess wird als Streck-Biege-Richten oder Zunderbrechen bezeichnet.to Achieving a good surface quality, in particular in the production of metallic bands, z. B. a scale hot strip with a hot acid solution very heavily wetted by the oxide layer completely from the Strip surface to remove before further processing z. B. is supplied by cold rolling. To the process of To influence stain by means of hot acid, before the start of the process, the closed scale surface by strong bending around several small rolls across to actual Tape direction, broken to acid attack facilitate. Positive side effect is that by bending The tape tension necessary for the rollers while bending the Band is lengthened in such a way that broadband ranges are largely all be brought to the same length and thus flatness error can be eliminated in the tape. The whole process will be referred to as stretch-bend straightening or scale breakage.
Den durch das Streck-Biege-Richten aufgebrochenen Zunder kann man zur Entlastung des Säurebades z. B. durch Abblasen, Abbürsten oder Abspritzen zum Teil schon vorher beseitigen. Ein Verfahren hierzu ist das Beaufschlagen der Oberfläche mit Kryogenen. Unter Kryogenen werden generell und auch hier Stoffe mit extrem niedrigen Temperaturen verstanden. Primär gedacht ist im Rahmen dieser Erfindung dabei an tiefgekühlte Gase in flüssiger Form wie Stickstoff oder an Trockeneis.The by the stretch-bending-straightening broken tinder you can to Relief of the acid bath z. B. by blowing off, brushing Or partially eliminate cumshot before. A procedure this is the application of cryogenic to the surface. Cryogens generally and here also substances with extreme low temperatures understood. Primary thought is in The scope of this invention in this case of frozen gases in liquid form like nitrogen or on dry ice.

Es hat sich gezeigt, dass der Erfolg der Entzunderung oder Reinigung der Oberfläche eines Bandes oder einer Bramme auch beim Einsatz von Kryogen nicht immer den gewünschten Erfolg hat.It has been shown to be the success of descaling or cleaning the surface of a tape or a slab also when Use of cryogen does not always give the desired success Has.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zum Entzundern bzw. Reinigen eines Bandes so weiterzuentwickeln, und eine entsprechende Vorrichtung vorzuschlagen, dass beim Einsatz eines Kryogens eine bessere Entzunderungs- bzw. Reinigungswirkung erreicht werden kann.Of the The present invention is therefore based on the object, a method to further develop the descaling or cleaning of a band, and to propose a corresponding device that during use a cryogen a better descaling or cleaning effect can be achieved.
Die Lösung dieser Aufgabe durch die Erfindung ist verfahrenstechnisch dadurch gekennzeichnet, dass vor dem Aufbringen des Kryogens eine minimale Menge Wasser auf die zu entzundernde oder zu reinigende Oberfläche aufgebracht wird. Die Wassermenge hat die Aufgabe, einerseits die Verunreinigungen zu binden und andererseits beim Zunder in Risse und kleine Öffnungen (Poren) einzudringen um beim Auftreffen des Kryogens schlagartig zu vereisen und das Absprengen z. B. der Zunderschicht zu unterstützen. Um den thermischen Effekt des Entzunderns bzw. Reinigens nicht zu dämpfen, darf die Wassermenge nicht zu groß gewählt werden.The Solution of this problem by the invention is procedurally characterized in that prior to the application of the cryogen a minimum amount of water to be descaled or cleaned Surface is applied. The amount of water has the task on the one hand to bind the impurities and on the other hand in the Tinder in cracks and small openings (pores) penetrate to suddenly ice on impact of the cryogen and the Break off z. B. to support the scale layer. Around not to dampen the thermal effect of descaling or cleaning, The amount of water must not be too large.
Als Kryogen kommt bevorzugt flüssiger Stickstoff oder Trockeneis zum Einsatz.When Cryogen is preferably liquid nitrogen or dry ice for use.
Eine
bevorzugte Weiterbildung sieht vor, dass beim Reinigen bzw. Entzundern
von Bandmaterial das Band zur Unterstützung der Reinigung
bzw. der Entzunderung um eine oder mehrere, quer zur Bandlaufrichtung
angebrachte Rolle gebogen wird. Durch die Biegeverformung erfolgt
eine starke Dehnung der jeweiligen Oberseite des Bandes. Dabei gibt
es im Grundsatz
- – Es wird vor der Biegeverformung das Wasser in definierter Menge aufgebracht, damit sich ein dünner Film auf der Oberfläche bilden kann bzw. das Wasser in die Poren des Zunders eindringt. Während der Biegeverformung wird dann auf die jeweilige Oberseite (Außenseite der Biegung) das Kryogen aufgebracht. Dabei ergänzen sich Biegespannungen und thermische Spannungen beim Absprengen des Zunders.
- – Das Wasser wird genau während der Biegeumformung auf die jeweilige Bandoberseite (Außenseite der Biegung) aufgebracht, wobei beim Enzundern die Zunderschicht aufreißt (Zunderbrechen vor einer Säurebeize) und das Wasser in diese Poren tief eindringen kann. Nach dem Durchlaufen des Biegeprozesses wird dann auf die mit Wasser getränkten Oberflächen des Bandes das Kryogen aufgebracht und der Zunder entfernt.
- - The water is applied in a defined amount before the bending deformation, so that a thin film can form on the surface or the water penetrates into the pores of the scale. During bending deformation, the cryogen is then applied to the respective upper side (outside of the bend). In this case, bending stresses and thermal stresses complement each other when the scale is blown off.
- - The water is applied exactly during the bending deformation on the respective upper side of the strip (outside of the bend), during the Enzundern the scale layer ruptures (zunderbrechen an acid pickle) and the water can penetrate deeply into these pores. After passing through the bending process, the cryogen is then applied to the water-soaked surfaces of the belt and the scale removed.
Bei der Biegeverformung kann es sich sowohl um ein Biege-Richten als auch ein Streck-Biege-Richtverfahren oder artverwandtes Verfahren handeln. Je nach Verfahrensablauf, wird das Wasser bzw. das Kryogen bevorzugt in dem Bereich der max. Bandkrümmung bzw. Biegung auf die Bandoberfläche aufgebracht. Dies ist meist im Bereich der Biegekassetten der Fall.The bending deformation may be both a bending-straightening and a stretch-bending straightening process or related method act. Depending on the procedure, the water or the cryogen is preferably in the range of max. Band curvature or bending applied to the strip surface. This is usually the case in the field of bending cassettes.
