Definitions

• the invention relates to a winding furnace, in particular a winding furnace for Steckel mill, in which a hot-rolled strip in the forward and Hertransport each reversing on a furnace drum in the furnace inside and is optionally heated, comprising mounted on the movable furnace flap of the winding furnace Leittician for threading and / or guiding the rolled strip, wherein the furnace flap and the winding furnace are separate structures, the furnace flap is disposed on a below the winding furnace part of a roller table frame and the furnace flap is divided into at least two mutually hinged elements and both flap elements connected via a flap bearing and are designed pivotally.
• Pressure roller is provided, which lays against the Entzu mattersrolle when pivoting the tilting table and together with this forms a stripper pulls the unwinding the strip-shaped rolling stock of the reel drum and the scraper is slidably mounted.
• DE 685 904 describes a reversing mill for rolling blocks into strips and strips with coiler ovens arranged on both sides of the rolling mill and height-adjustable drive rolls and adjustable guides for the rolling stock arranged on both sides of the rolling mill, to which the rolled stock is to a certain extent Rolled back and forth and, as soon as it has been rewound, is in the coiler ovens up and down coiled. It is triggered by the starting and reversing switch for the drive motor of the work rolls both a control device for hiring the drive rollers on the inlet and outlet side and a change of the guide rails when changing the direction of the work rolls.
• No. 5,637,249 describes that the metal strip can be wound up almost completely in the winding furnace with the aid of a heated driving device in the furnace opening.
• the driver should be heated by a separate heat source.
• This solution proves to be technically very complicated and can only minimize the length of the inadmissible cooling tape. Because in order to be able to reliably ensure that the tape can be conveyed out of the winding furnace out again, the tape must not leave the driving device. However, this means that under operating conditions, the end of the tape is never conveyed into the winding furnace.
• EP 0 619 377 B1 explains the idea of a driver in combination with a three-roller bending device and a scraper.
• two rolls were installed in the wall of the winding furnace so that they are partly in and partly outside the furnace.
• the kiln drum is used as the third roll to be bent. Since the collar grows on the furnace drum with each turn in its diameter, the furnace drum is mounted so that it can be moved by means of hydraulic cylinders in a guide.
• the ribbon end is held in the furnace in the blowing and bending device, between one of the rolls, which is built into the wall of the winding furnace, and the collar.
• the scraper should ensure that even if the end of the tape on the collar sticks, this can be solved and the end of the tape is safely discharged from the oven.
• a disadvantage of this device is that the tape, while stored in the winding furnace, is in contact with the rollers which are arranged in the wall of the winding furnace, which are significantly colder than the belt itself. This has the consequence that the end of the tape cools unacceptably and only, as in the documents listed above, with even more sophisticated facilities, the supercooled tape length is minimized. In addition, the insulation of the winding furnace is weakened by the incorporation of the rollers in the furnace wall and increases its energy consumption.
• DE 32 24621 A1 describes a reel furnace with a horizontal reel, the mandrel is seconded within a heat shield, with a reel mandrel enclosing, pressure rollers for an up or unwound tape having tape guide, the two of opposite sides pressed against the reel mandrel, cylindrical Guiding segments includes, of which the upstream in the winding sense guide segment connects to a pivotally mounted below the coiler mandrel belt bridge for the supply and Abförde- tion of the band.
• the coiler oven is characterized in that the two guide segments are fixed to arranged outside the heat shield rockers that are transverse to the pressing direction of the guide segments and parallel to the coiler mandrel pivot axes, that in the Aufwickelsinn downstream guide segment forms the belt scraper with its trailing edge and that the equipped with a separate pivot drive band bridge preferably consists of a roller table, the reel mandrel facing end roller serves as a pressure roller for the band. It is stated on page 3 of this document that it is known from DE - PS 811 837 to wind the band completely on the coiler mandrel of the coiler furnace. However, this complete winding of the tape makes it necessary to provide special Bandabstreifer that allow unwinding of the tape at a reversal of the direction of rotation of the reel.
• the invention is therefore based on the object to simplify the known, mechanically complex, constructions and to avoid the disadvantages mentioned above.
• This object is achieved in that is formed in a winding furnace according to the preamble of claim 1 of the winding furnace in the furnace interior with only one furnace roller.
• the preamble of claim 1 is known from WO 03/048 397 A1.
• the oven roller can be placed anywhere on the winding. In order to be able to control the end of the tape well, however, it is advantageous to do this in the area of the upper half of the roll.
• the oven roll is mounted like the oven drum in the winding oven.
• the furnace roll is built up, just like the furnace drum, with a hot jacket mounted on a cooled axle. This has the advantage that with the usual heat-resistant material of the roll shell temperatures of over 95O 0 C can be achieved.
• placing the oven roll on the winding leads to a negligible cooling at the Aufsetzstelle. For thin strip thicknesses, eg smaller than e mm, even a heating up of the placement point takes place.
• the pegs of the oven roll are stored in two independent levers outside the oven.
• the levers are supported in bearing blocks which are externally mounted to the construction of the furnace.
• a hydraulic cylinder or other type of drive is attached to one or both levers, which is also supported on the construction of the furnace.
• shields are attached to the levers, which close the openings in the furnace wall, which are required to pivot around the furnace roll.
• the size of the recesses is determined by the swivel range of the furnace roll. The size of the shields is selected so that even in the uppermost as well as in the lowest position of the furnace roll, the recesses are closed.
• the drive is for example via an electric motor which is connected via a propeller shaft with the furnace roller.
• a propeller shaft with the furnace roller.
• other drives are conceivable, such as e.g. a fluid motor, which is mounted directly on the furnace roll.
• a medium is supplied to the fluid motor, e.g. Water, air, oil or the like.
• the winding furnace is completely closed with appropriate execution of the furnace flaps.
• the drum can be rotated back and forth during the time that the winding stored in the winding oven is stored.
• the angular range in which the drum can be rotated depends on the Aufsetzddling the oven roll and how far the end of the tape is wound up.
• the oven roll By turning the drum back and forth, the oven roll also rotates to ensure that it remains evenly heated and does not cool down the place where it is placed.
• the furnace flap In order to convey the tape safely out of the winding furnace, the furnace flap, with which the winding furnace is closed, carried out so that the cover plate of the furnace flap is placed to guide the end of the tape during removal already in the winding furnace.
• a scraper is not required in the device according to the invention. The end of the tape will not stick to the reel as the end of the reel does not rest on the reel or is pressed against the reel by the furnace reel or rolled over by it.
• Figure 1 is a cross-section of a winding oven with open oven door during winding of the rolled strip.
• Figure 2 is a cross-section of a winding furnace with closed oven door and fully wound rolled strip.

• a winding furnace 1 is shown in cross section, in which a rolled strip 2 is wound on a furnace drum 3 in the furnace interior 4.
• the oven door 5 is attached to a roller table frame 7 and consists of a flap element 8 and a flap element 9, which are connected to each other via a flap bearing 10 and pivotally formed.
• the rolled strip 2 is pressed by a furnace roller 11, consisting of roller shell 12 and roller axis 13, to the already wound on the furnace drum 3 turns.
• the pressing is done by lever 14, the are mounted outside the winding furnace 1.
• the levers 14 are coupled, for example, with hydraulic cylinders 15.
• the roller axis 13 is in recesses 16, which are located in the housing of the winding furnace 1, moves.
• the recesses are covered by attached to the levers 14, outer heat shields (not shown).
• FIG. 2 shows the winding oven 2 with closed oven flap 5.
• the oven drum 3 is rotated in such a way that the ends of the rolled strip always move between the oven roller 11 and the oven door 5.
• the furnace drum 3 is rotated in such a way that the rolled strip 2 moves in the direction of the furnace flap 5, in particular in the direction of the flap element 8.
• the oven door 5 is not completely opened, as moved down, but a cover plate 17 by means of an adjusting element 18 is rotated about a plate bearing 19. This creates a guide for the rolled strip 2 and an opening of the winding furnace through which the rolled strip passes on the roller table.
