Die Erfindung betrifft einen Coilboxofen mit einer Heizeinrichtung zum Wiedererwärmen eines Coils auf Walztemperatur und einem Sattel zur Aufnahme des wiederzuerwärmenden Coils, wobei der Sattel mindestens zwei das Coil an dessen Außenumfang tangential abstützende Auflageflächen aufweist.The invention relates to a coil box furnace with a heating device to reheat a coil Rolling temperature and a saddle to accommodate the rewarming coils, with the saddle at least two the coil has tangentially supporting surfaces on its outer circumference.
Die Erzeugung von Warmband erzwingt im Rahmen einer kostenoptimierten Fertigung zunehmend den Einsatz peripherer Einrichtungen zur Minimierung von Materialausschuß. Hierzu zählen insbesondere Einrichtungen, mit denen ein in der Prozeßlinie befindliches Vorband im Störungsfalle gegebenenfalls so konserviert werden kann, daß es nach Behebung der Störung zur Fortsetzung der Fertigung in die Prozeßlinie wieder eingeführt werden kann.The production of hot strip enforces within a cost-optimized manufacturing increasingly use peripheral facilities to minimize Material Committee. These include in particular Facilities with which one in the process line Supporting act in the event of a malfunction, if necessary can be preserved that after the fault has been rectified to continue production in the process line again can be introduced.
Eine Coilbox im Einlauf einer Fertigstaffel ermöglicht ein Aufwickeln und eine zeitliche Pufferung des Vorbandes vor dem Einsatz in die Fertigstaffel von etwa zehn Minuten für Weichstahlsorten. Eine derartige Anordnung einer Coilbox ist beispielsweise aus der DE-OS 2 256 030 bekannt. Edelstahlgüten, die nur in einem engen Temperaturbereich gewalzt werden können, bieten diese Reserven allerings nicht, so daß solche Vorbänder bei mehrminütigen Störungen als Coil abgelegt werden, jedoch bislang nicht wieder in die Walzlinie eingeführt werden konnten. A coil box in the infeed of a prefabricated season enables winding and temporary buffering of the opening before use in the pre-season of about ten Minutes for mild steel grades. Such an arrangement a coil box is for example from DE-OS 2 256 030 known. Stainless steel grades that are only available in a tight Temperature range can be rolled, they offer Reserves, however, do not, so that such supporting strips faults lasting several minutes are stored as a coil, however have not yet been reintroduced into the rolling line could.
Aus der EP 0 734 793 A1 ist bekannt, Coilboxen vor und hinter einem Reversiergerüst einzusetzen. Ebenso ist es aus dieser Druckschrift bekannt, einen Ofen vorzusehen, in dem das Band nach Durchlauf des Reversiergerüstes wiedererwärmt wird. Mit dem Einsatz eines Wiedererwärmungsofens an der Coilbox können, die voranstehend erwähnten Probleme beseitigt werden, indem anfallende Coilboxvorbänder auf Walztemperatur aufgeheizt und wieder in den Walzprozeß integriert werden.EP 0 734 793 A1 discloses coil boxes in front of and insert behind a reversing scaffold. It is the same known from this document to provide an oven in the belt after passing through the reversing stand is reheated.

Ein aus der Praxis bekannter Coilboxofen ist als Kammerofen mit einem feststehenden und einem verfahrbaren Gehäuseteil ausgebildet. Der verfahrbare Gehäuseteil weist einen elektromechanischen Antrieb auf und ist auf Schienenrädern verfahrbar. Die Beheizung des Ofens erfolgt durch mäanderförmigen Heizleiter, die an den vier Seitenwänden des Ofens installiert und zu einzelnen Regelgruppen zusammengefaßt sind. Der nicht extra beheizte kreissegmentförmige Aufnahmesattel für das Coil steht auf einer Bodenplatte aus feuerfestem Beton und einem Gerüst aus warmfestem Stahl (vgl. Fig. 1).A coil box furnace known from practice is as Chamber furnace with one fixed and one movable Housing part formed. The movable housing part has an electromechanical drive and is on Rail wheels can be moved. Heating the oven is made by meandering heating conductors connected to the four Side walls of the furnace installed and individual Rule groups are summarized. Not extra heated circular segment shaped saddle for the coil stands on a base plate made of fireproof concrete and a frame made of heat-resistant steel (see. Fig. 1).
Bei diesem bekannten Coilboxofen wurden jedoch in dem in den Walzprozeß wiedereingesetzten Vorband erhebliche periodische Temperaturänderungen festgestellt, die sich auf das Walzverhalten in der Fertigstafel und auf die erreichbaren Toleranzen der Endwalzdicke ungünstigIn this known coil box furnace, however, in the rolling process re-used considerable advance periodic changes in temperature are noted on the rolling behavior in the finished sheet and on the achievable tolerances of the final roll thickness unfavorable
Die US-A-5 383 651 beschreibt einen Sattel zur Auflage eines Coils beim Glühen, welcher zwei das Coil außen tangential abstützende Auflageflächen aufweist. Wird dieser Sattel in einem Coilboxofen eingesetzt, so kann das darin zwischengespeicherte Coil gleichmäßig auf Walztemperatur aufgeheizt werden, so daß sich die temperaturbedingten Enddickentoleranzen des fertiggewalzten Bandes minimieren lassen.US-A-5 383 651 describes a saddle for supporting a coil during annealing, which two the coil has tangentially supporting surfaces on the outside. This saddle is in a coil box oven used, the coil temporarily stored therein are evenly heated to the rolling temperature, so that the temperature-related final thickness tolerances of the finished rolled strip can be minimized.
Bekannte Sättel von Coilboxöfen sind Schweißkonstruktionen, die beim Zwischenglühen der Coils Temperaturen von bis zu 1160°C über lange Zeit ausgesetzt sind. Dies führt häufig zu einer frühzeitigen Zerstörung der Schweißnähte.Known saddles of coil box furnaces are welded structures that heat up when the coils are annealed exposed to temperatures of up to 1160 ° C for a long time. This often leads to premature destruction of the Welds.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß der Sattel aus ineinandergestechten Brammen aufgebaut ist. Dadurch sind Schweißnähte vermieden.To solve this problem, the invention suggested that the saddle is built from slabs cut into each other. Thereby weld seams are avoided.
Die periodischen Temperaturänderungen in dem aus dem bekannten Coilboxofen entnommenen Vorband sind durch den kreissegmentförmigen Aufnahmesattel des erwähnten Coilboxofens bedingt. Durch den kreisbogenförmigen Aufnahmesattel wird dem aufliegenden Band durch radiale Wärmeleitung in einem relativ großen Bereich Wärmeenergie entzogen, was zu den erwähnten periodischen Temperaturänderungen führt.The periodic temperature changes in the opening strip taken from the known coil box furnace through the circular segment-shaped receiving saddle of the mentioned Coil box furnace conditional. Through the circular arc Pick-up saddle is passed through the tape radial heat conduction in a relatively large area Extracted thermal energy, leading to the periodic mentioned Changes in temperature.
Bei dem erfindungsgemäßen Coilboxofen mit das Coil tangential abstützenden Auflageflächen des Sattels ist dagegen der Auflagebereich des Aufnahmesattels wesentlich verkleinert und damit der Wärmeverlust erheblich reduziert, so daß das Walzverhalten in der Fertigstaffel und die Dickentoleranzen des fertiggewalzten Bandes entsprechend verbessert sind.In contrast, in the coil box furnace according to the invention with the saddle's supporting surfaces of the saddle tangentially Support area of the mounting saddle significantly reduced and thus significantly reduces heat loss, so that the rolling behavior in the finishing line and the Thickness tolerances of the finished rolled strip accordingly are improved.
Der Sattel des erfindungsgemäßen Coilboxofens ist zweckmäßig trapezfömig.The saddle of the coil box furnace according to the invention is expediently trapezoidal.
Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Lösung besteht darin, daß die Auflageflächen des Sattels aus einer Vielzahl in Richtung der Coilbreite beabstandeter Erhebungen gebildet sind. Hierdurch wird der tatsächliche Kontaktbereich zwischen Sattel und Coil weiter verringert. Die Brammen des Sattels können vorzugsweise aus Edelstahl bestehen. Zur Stabilisierung des erfindungsmäßen Aufnahmesattels ist im Gegensatz zu dem oben erwähnten kreissegmentförmigen Sattel kein Feuerfestmaterial erforderlich.An advantageous embodiment of the invention Solution is that the bearing surfaces of the saddle from a variety in the direction of the coil width spaced surveys are formed. This will the actual contact area between the saddle and the coil further decreased. The saddle slabs can preferably be made of Stainless steel. To stabilize the Invention saddle is in contrast to that above-mentioned circular segment-shaped saddle no Refractory material required.
Desweiteren ist es vorteilhaft, wenn, wie nach einer weiteren Ausgestaltung der erfindungsgemäßen Lösung vorgesehen, neben den Wänden des Coilboxofens auch der Aufnahmesattel mit einer Heizeinrichtung versehen ist. Dabei kann vorzugsweise eine induktive Sattelheizung verwendet werden.Furthermore, it is advantageous if, as after a further embodiment of the solution according to the invention provided, in addition to the walls of the coil box furnace Recording saddle is provided with a heating device. An inductive saddle heater can preferably be used be used.
Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Coilboxofens besteht darin, daß dieser ferner eine Vorrichtung zum Drehen oder Pendeln des Coils aufweist. Diese Ausgestaltung trägt ebenfalls zu einer Vergleichmäßigung des Temperaturprofils des in die Fertigstaffel wieder eingesetzten Vorbandes bei.Another advantageous embodiment of the Coil box furnace according to the invention is that this a device for rotating or oscillating the coil having. This configuration also contributes to Uniformization of the temperature profile in the Finished relaunch of the opening act.
Im Hinblick auf unterschiedliche Coildurchmesser und/oder Coilbreiten ist es auch günstig, wenn der Abstand der Auflageflächen in bezug auf den Coildurchmesser und/oder die Coilbreite einstellbar ist.With regard to different coil diameters and / or Coil widths, it is also convenient if the distance of the Contact surfaces in relation to the coil diameter and / or the coil width is adjustable.
Nach einer weiteren vorteilhaften Ausgestaltung kann vorgesehen sein, daß die Auflageflächen durch Scheibenrollen mit entlang der Rollenlängsachsen beabstandeten Kreisscheiben gebildet sind. Dabei kann zum Drehen oder Pendeln des Coils mindestens eine der Scheibenrollen mit einem Drehantrieb gekoppelt sein. According to a further advantageous embodiment, be provided that the bearing surfaces by Disc rollers with along the longitudinal axes of the rollers spaced circular disks are formed. It can be used for Rotate or swing the coil at least one of the Disc rollers can be coupled with a rotary drive.
