Definitions

  • the invention relates to a strip casting machine for producing a metal strip, with two casting rolls arranged next to one another, forming a casting gap, which are rotatably supported, the casting rolls being displaceable from the casting position into a maintenance position and vice versa, and a method for controlling the strip casting machine ,
  • narrow sides limit the casting gap.
  • the narrow sides are worn both by the friction on the casting rolls and in the lower part by the friction of the solidified strip due to abrasive wear and must be replaced during a casting break.
  • a narrow side changing device e.g. B. robots, which are arranged on each side of the machine on the casting platform, removed upwards from the position.
  • Japanese laid-open patent publication JP-5-32 95 83 A describes such a robot for changing the narrow sides.
  • the casting rolls are stationary and fixedly arranged below a rotating tower and a distribution vessel or the like. If, for example, these casting rolls Regrinding must be revised or replaced, this is associated with complex dismantling or assembly work, since these casters are difficult to access and because of their weight they have to be carried away with a crane or re-used with millimeter accuracy.
  • the connection or disconnection of the water connections or the electrical connection lines is connected due to the existing accessibility with cumbersome work processes, in which even the frame bearing the castors has to be divided.
  • the present invention was based on the object of creating a strip casting machine of the type mentioned at the beginning, in which optimum access to the machine and in particular also to the casting rolls is made possible, by means of which quick maintenance or a change thereof can be carried out, and in which the availability of the strip casting machine for casting and thus the casting performance of the same can be increased.
  • the object is achieved according to the invention in that the casting rolls can be moved away from the casting position by such a distance that a second pair of prepared casting rolls can be moved into the casting position.
  • the casting rollers are rotatably mounted on a frame and the frame is displaceable by the distance mentioned from the casting position and a second frame provided with prepared casting rollers is displaceable into the casting position.
  • FIG. 4 shows a schematic view of the casting installation from above
  • FIG. 5 shows another variant of a schematic view of a two-strand casting installation from above.
  • FIG. 1 shows a strip casting machine 20 of a casting system 10 of a metal strip 15 that can be produced in a continuous casting process, in particular a steel strip.
  • This belt casting machine 20 stands on a carrier system 12 and is supplied with molten metal from a distributor vessel (not shown) standing above it, as is known in conventional continuous casting plants.
  • this band casting machine 20 has two casting rolls 22, 24 arranged essentially parallel to one another with an approximately horizontal axis of rotation, which are provided on both ends with a side seal 25, whereby an all-round closed opening with a downwardly open casting gap is formed.
  • the casters 22, 24 are rotatably supported on both sides on a frame 32 and driven by a motor.
  • the frame 32, 32 ' can be pivoted about an axis 71 by an adjusting means 72 for the purpose of adjusting the width of the casting gap with its one part 32' and the casting roller 22 associated therewith.
  • the casting rolls 22, 24 are each formed from a motor-driven cylindrical jacket and from a fixed axis 75 which rotatably supports the latter, the respective axis 75 being supported on both sides of the frame frame 32, 32 '.
  • This execution with the fixed axes 75 enables a simple construction of the same together with the frame.
  • the casting rolls 22, 24 with the frame 32 and the side seals 25 are surrounded all around by a closable housing 30, the housing interior 33 being filled with a protective gas, preferably an inert gas, during the casting.
  • This box-shaped housing 30 is very advantageously arranged both laterally and at the top at a distance from the casting rolls 22, 24 or from the machine stand 32.
  • this housing 30 Provided on the top of this housing 30 is a cover 35 lying approximately horizontally thereon, which can be displaced from the closed position shown to a raised position 35 'and from this to a horizontally pushed position 35 ".
  • a cover 35 lies approximately horizontally thereon, which can be displaced from the closed position shown to a raised position 35 'and from this to a horizontally pushed position 35 ".
  • it has to the side Rollers 27, which are guided on corresponding rails 28.
  • the cover 35 In the closed position shown, the cover 35 is advantageously lowered to the level of the base 14 in order to achieve the intended tightness of the housing 30.
  • the housing 30 is also assigned openings 39 which can be closed laterally by means of doors 36 and which serve to ensure that the side seals 25 of the casting rollers 22, 24 each pass from the operating position shown through these openings 39 from a manipulator 40 which can be moved outside the housing 30 that can be guided into or into the housing 30.
  • the respective manipulator 40 has a holding arm 41, to which the side seal 25 is fastened, which can be moved by this manipulator 40 from an operating to a retracted maintenance position 25 'and vice versa.
  • the opening 39 that is not closed can be sealed by means of a separate protective cover 38.
  • This protective cover 38 encloses the Manipulator 40 and is therefore pressed laterally against the housing 30.
  • cassettes 88 for the introduction and removal of side seals 25 are also indicated.
  • two such manipulators 40 are installed on both sides of the housing 30, which alternately bring up the corresponding side seals 25 on the end faces of the casting rolls 22, 24 and press the latter against the casting rolls in a precisely positioned position during the casting.
  • the cast metal strip 15 is guided in an additional longitudinal housing 44, which forms a chamber 45, in which a protective gas is also contained in order to protect the metal strip 15 against contact with oxygen and thus in particular against scale formation.
  • a plurality of rollers 46 and pressing rollers 47 are arranged in this chamber 45, so that the metal strip 15 is guided through this longitudinal housing 44 and through an opening 58 sealed at its end. After exiting from this housing 44, this metal strip can, for example, be rolled, cooled, rolled up or otherwise processed.
  • the longitudinal housing 44 has an indentation 49 below the opening 30 ′′ or the casting gap, in which there is a collecting container 52 placed in a system base 61.
  • This collecting container 52 has the task, in the event of a leak, of the liquid emerging from the bottom of the casting rollers Swiveling guide flaps 54, 55 are arranged above this container 52, which form a passage in the position shown, but serve as a guideway for the metal strip 15 in the dot-dash pivot position 54 ', 55'.
  • the housing 30 has a feed line (not shown in more detail) for blowing protective gas into its interior 33, which can be cooled and returned by means of a gas circuit. After a casting process has been completed and before the housing is opened, the protective gas can be drawn off into a reservoir and, if necessary, the air can be filtered out in it.
  • the rails 48, 48 ' which carry the housing 30 and are designed as pairs are - as can also be seen in FIG. 2 - separated from the remaining length in the region of the casting position G and in height by lifting cylinders 51 or the like fastened to a structure 62 adjustable. In FIG. 1 they are shown together with the housing 30 in the lowered position, but in FIG. 2 in the position flush with the adjacent rails 48 '.
  • this change of the casting rolls 22, 24 can be carried out on the fly, i.e. that the pouring tube projecting through the cover 35 between the casting rollers 22, 24 can be held in position without lifting the distributor vessel 18 holding it.
  • the cover 35 is raised during the change and the casting rollers 22, 24 are moved horizontally away from the housing 30 along their axes of rotation after the side seals 25 have been removed, and accordingly the new casting rollers, for example with different widths, are fed in such a way that the pouring tube is non-contact between them comes to a standstill again.
  • the pouring can continue without the distribution vessel 18 having to be emptied.
  • only the closing device has to be opened at the outlet thereof. A considerable increase in performance can thus be achieved with this strip casting machine according to the invention.
  • the housing 30 with the used casting rolls 22, 24 contained therein is arranged around such a diameter.
  • Punch arranged to be displaceable away from the casting position G such that a second housing 30 'with prepared casting rollers can be moved into the casting position G.
  • the distance between the casting position G and the maintenance position W is advantageously a few housings. Casting roll lengths, so that in the maintenance position you can work undisturbed by the casting process. This depends on the conditions of a single casting plant.
  • a rotating tower 81 which is conventional per se, holds a pan 82, from which the molten steel is poured into a distribution vessel 18 and from there between the casting rolls in the casting position G.
  • the metal strip emerging below these casting rolls is then conducted away in the direction of arrow 83.
  • the casting rolls 22, 24 are serviced, for example by turning or grinding or other surface treatments, or, if appropriate, replaced by indicated new casting rolls.
  • These casters 22, 24 have been pushed away together with a housing 30 on the rails 48 '.
  • Distribution vessels 18, 18 ' are also provided for use. These could also be swiveled into the casting position by the rotating tower.
  • FIG. 5 shows a casting plant 80 with two adjacent strands, in which, in contrast to that according to FIG. 4, two rotating towers 81 and one maintenance position W each are provided.
  • two housings 30 with casting rollers 22, 24 are stationed, which advantageously also serves as a maintenance position.
  • the invention could also be applied very advantageously in a two-strand casting installation in which two strands are supplied with liquid melt in a distributor vessel with two outlets. There would then be two housings with two casters next to each other in use. A flying change could be carried out by changing one or the other housing, while the other is poured on.
  • the side seals could also be arranged on the frame and brought into the maintenance position with this.
  • the housing 30 could also remain in the casting position. Then only the frame with corresponding wheels and the casters would be moved away.
  • the housing could also be guided on continuous rails that cannot be lowered.
  • the water connection would then have to be carried out by a plug connection, pressed-on media plate or the like.
