Definitions

  • the invention relates to a device for producing a cast metal strip with an amorphous and / or finely crystalline structure, with a casting device in which molten metal can be applied to a moving heat sink via a casting nozzle, with a reel with winding aids and with between the casting device and the reel arranged guide and transport means, which form a band guide channel and have the band with a gaseous, in particular cooling medium blowing nozzles.
  • the strip cast between two casting wheels is placed under tension by a casting wheel directly downstream of the driving rollers in such a way that it is pulled firmly against the cooled jacket of the casting wheel.
  • This tension can only be applied if the tape has sufficient tensile strength due to cooling.
  • the belt is also exposed to a gaseous cooling medium on the free side in the area of the casting wheel.
  • the belt is guided between the cooling wheel and the take-up reel in a floating manner between the blowing jets by blowing nozzles arranged on both sides of the belt. Blower nozzles are also arranged in the area of the take-up reel and blow a cooling gaseous medium onto the free side of the strip (EP 0 081 175 B1).
  • the invention has for its object to provide a winding device of the type mentioned, which enables precise winding at high belt speeds.
  • the strip is cooled quickly and without tensile stress, whereby the cooling in the area of the cooling wheel can be reinforced by the gaseous medium of the blowing nozzles arranged in this area.
  • the band is pressed against the cooling wheel without tension by the gaseous medium of these blowing nozzles.
  • Driver roles loading the tape are not required.
  • the belt does not have to be subjected to a comparable load to the tensile stress applied by driver rollers. Here it is conveyed due to its own weight or possibly additionally through the flow of the gaseous medium. Because of the narrowness of the guide channel and the preferably supporting flow of the gaseous medium, even very thin tape in the p. Area easily promoted.
  • the tape transfer and tape separating device enables the tape aligned by the catching device to be connected to the take-up reel without interrupting the transport of the tape to the take-up reel.
  • the device can be designed in an advantageous manner by a number of features.
  • a component of the blowing direction of the blowing nozzles should point in the belt conveying direction.
  • cooling wheels with concentrically arranged walls are provided on the first section of the belt guide channel, they should be arranged in the manner of S-roller pairs.
  • a number of measures can be provided for detaching and transferring the strip from the casting wheel to the subsequent cooling wheel.
  • a tape detaching member can be arranged in the gusset of the shell of the casting wheel and the tape.
  • This can consist of a wedge, which is particularly equipped with blow nozzles.
  • a pressure roller for the belt should be provided in front of the entrance of the channel formed by the first cooling wheel and its wall. This can be designed as a roller-shaped brush, which is driven by friction rollers running on the jacket of the cooling wheel.
  • the flow through the belt guide channel in the conveying direction is preferably generated by a suction device connected to the end of the channel.
  • a suction device connected to the end of the channel.
  • blowing nozzles in the walls of the channel, the flow direction of which has a flow component pointing towards the end of the channel.
  • the catching device preferably consists of a pair of pinch rollers, the rollers of which can be moved apart to catch the band.
  • the pinch rollers should be driven to keep the tape taut when connecting to the reel and separator.
  • the take-up reel equipped with a tacking agent is assigned a pressing and separating device for the tape on the side opposite the tape guide plane.
  • An adhesive coating is suitable as a tack.
  • the pressing and separating device which can be moved against the take-up reel preferably consists of a brush and a knife arranged downstream in the direction of travel of the tape, which should be foldable so as not to damage the tape to be wound up.
  • the winding device it is possible with the winding device to use a reversible reel with which the strip can be transferred from the full reel to the empty reel on the fly.
  • a rolling device e.g. integrate a reduction or face roller set, preferably on a cooling wheel, in particular the second cooling wheel.
  • the band casting device consists of a container 1 filled with molten metal, a delivery or riser pipe 2 immersed therein, a pouring nozzle 3 and a moving heat sink in the form of a cooled casting wheel 4.
  • Band casting devices in this or a similar embodiment. are known. So that due to the centrifugal force acting on the belt 6, the belt 6 does not detach itself too soon from the jacket of the casting wheel 4, a guide 5, which is equipped with blowing nozzles, not shown, extends over the casting wheel 4 and is arranged on the jacket of the casting wheel 4 blow the band 6 and thereby press it against the jacket of the casting wheel 4.
  • This special design of the casting device is of secondary importance for the invention.

(See German patent applications P 35 21 778.2 and P 36 02 594.1). It is only important that the strip 6 has solidified at the detachment point of the belt 6 from the casting wheel 4. Sufficient tensile strength to apply a tape tension is not yet necessary here.
  • a wedge-shaped detaching member 7 is arranged in the gusset between the jacket of the casting wheel 4 and the belt 6, which can be equipped with blowing nozzles to support the detachment.
  • This detaching element 7 is followed by a brush roller 8 with friction rollers at its ends, which run on the jacket of a first cooling wheel 9.
  • the brush roller 8 presses the belt 6 against the jacket of the cooling wheel 9, so that, above all, the beginning of the belt easily runs into the entrance of a guide channel which is formed by the jacket of the cooling wheel 9 and a guide wall 10 arranged concentrically therewith.
  • the first cooling wheel 9 is followed by a second cooling wheel 11 with a correspondingly arranged guide wall 12.
  • the belt 6 is guided in an S-shape over the casting wheel 4 and the two cooling wheels 9, 11.
  • the guide walls 10, 12 on the cooling wheels 9, 11 are equipped with blowing nozzles which blow a cooling medium against the band 6, so that the band 6 is pressed firmly against the shells of the cooling wheels 9, 11 for the purpose of intensive contact cooling.
  • a cooled medium in particular air or an inert gas, is preferably used as the blowing medium. This applies above all to the blowing medium of the nozzles on casting wheel 4.
  • a brush roller 13 is arranged as an additional guide, which is driven by a friction wheel running on the jacket of the cooling wheel 11.
  • a flat guide channel 14 adjoins the guide channel 11, 12.
  • the width of this guide channel 14 perpendicular to the band plane is smaller than the band width.
  • the guide channel 14 can consist of a U-profile, which is by a lateral Lid can be closed. By opening the cover and by lateral adjustment, it is possible to release the band 6 guided through the channel 14.
  • the strip thickness can be measured with an uninterrupted conveying of the strip 6 with a measuring device 17 which is only indicated.
  • a suction device 15 only indicated in the drawing, is connected, which allows a gas flow to flow through the channel from top to bottom.
  • a pair of pinch rollers 16 is provided at the lower exit of the guide channel 14.
  • the band 6, By clamping the band 6, it is fixed laterally. From this moment on, the guide channel 14 is therefore no longer required, but can be opened and moved out of the guide area.
