  • This embodiment with the fixed axles 75 allows a simple construction thereof 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, wherein the housing interior 33 is filled during the casting with a protective gas, preferably an inert gas.
  • a protective gas preferably an inert gas.
  • This box-shaped housing 30 is arranged very advantageously both laterally and at a distance from the casting rolls 22, 24 or to the machine stand 32.
  • this housing 30 On the upper side of this housing 30 there is provided a cover 35 which lies approximately horizontally on the latter and which can be displaced from the closed position shown into a raised position 35 'and from this into a horizontally pushed-away position 35 " , which are guided on corresponding rails 28. In the shown closed position, the cover 35 is advantageously lowered to the level of the bottom 14 in order to achieve the intended tightness of the housing 30.
  • the housing 30 are also laterally sealed by means of doors 36 closable openings 39, which serve that the Soabdichtonne 25 of the casting rolls 22, 24 of each one outside the housing 30 movable manipulator 40 from the operating position shown by these openings 39 from the or . Can be guided in the housing 30.
  • the respective manipulator 40 has for this purpose a holding arm 41, on which the side seal 25 is fixed, which can be moved by this manipulator 40 from an operating to a retracted maintenance position 25 'and vice versa.
  • a seal of the non-closed opening 39 can be brought about by means of a separate protective sheath 38. This protective cover 38 encloses the manipulator 40 and is therefore pressed against the side of the housing 30.
  • cassettes 88 for the introduction and removal of side seals 25 are indicated.
  • two such manipulators 40 are installed on both sides of the housing 30, which alternately introduce the corresponding side seals 25 at the end faces of the casting rolls 22, 24 and the latter press on the casting rolls during casting in a precisely positioned position.
  • the cast metal strip 15 is guided in an additional longitudinal housing 44, which forms a chamber 45, in which also a protective gas is contained in order to protect the metal strip 15 from contact with oxygen and thus in particular from scale formation.
  • a protective gas is contained in order to protect the metal strip 15 from contact with oxygen and thus in particular from scale formation.
  • this chamber 45 a plurality of rollers 46 and press rollers 47 are arranged so that the metal strip 15 is guided through this longitudinal housing 44 and through an end 58 sealed in it opening.
  • this metal strip can for example be rolled, cooled, rolled up or otherwise processed.
  • the longitudinal housing 44 below the opening 30 "or of the casting gap has a depression 49, in which there is a collecting container 52 placed in a plant bottom 61.
  • This collecting container 52 has the function of discharging the liquid emerging from the casting rolls in the event of leakage melt to catch without causing any damage.
  • pivotable guide flaps 54, 55 are arranged, which form a passage in the position shown, meanwhile serve in the dash-dotted pivot position 54 ', 55' as a guide track of the metal strip 15.
  • the housing 30 has a supply line not shown in detail for the injection of inert gas into its interior 33, which can be cooled by a gas circulation and recycled. After completion of a casting process and before the opening of the housing, the inert gas can be sucked into a memory and optionally the air is filtered out in this.

  • a new with prepared casting rollers 30 is moved in casting position G and lowered. Then, the side seals 25 are pressed by means of the manipulators 40 to the end faces of the casting rolls 22, 24 with a defined pressure, the protective sheaths 38 and the lid 35 is tightly connected to the housing 30 and the latter inertized in its interior by the inert gas.
  • This change of the casting rolls 22, 24 can be carried out as a further advantage of the invention so-called flying, i. that the pouring tube projecting through the lid 35 between the casting rolls 22, 24 can be kept positioned without lifting the distributor vessel 18 holding this.
  • the lid 35 is raised when changing and the casting rolls 22, 24 are moved away horizontally after removing the side seals 25 from the housing 30 along their axes of rotation and accordingly, the new, for example, provided with other widths casting rolls supplied such that the pouring tube without contact between them comes to stand again. This allows further pouring without the distributor vessel 18 having to be emptied.
  • When re-casting only the closing organ at the outlet of the same must be opened. This makes it possible to achieve a considerable increase in performance with this strip casting machine according to the invention.
  • the housing 30 with the used therein casting rolls 22, 24 displaceably arranged by such a distance from the casting position G, that a second housing 30 'with prepared casting rolls in the casting position G is movable.
  • the distance between the Giessposition G and the maintenance position W some housing lengths, so that you can work undisturbed in the maintenance position of the pouring. This depends on the circumstances of a single casting plant.
  • FIG 4 shows this casting plant 10, which works with a strand.
  • a conventional turret 81 holds a ladle 82, from which the molten steel is poured into a distributor vessel 18 and from there between the casting rolls located in the casting position G. The metal strip emerging below between these casting rolls is then directed away in the direction of arrow 83.
  • the casting rolls 22, 24 are maintained, for example, by twisting or grinding or other surface treatments, or possibly replaced by indicated new casting rolls. These casting rolls 22, 24 have been pushed together with a housing 30 on the rails 48 '.
  • distribution vessels 18, 18 ' are provided for use. These could also be pivoted by the turret in Giessposition.
  • Figure 5 shows a casting plant 80 with two adjacent strands, in contrast to that after Figure 4 correspondingly two revolving towers 81 and one maintenance positions W each are.
  • two housings 30 with casting rolls 22, 24 are stationed between the casting positions G of the two strands, which likewise advantageously serves as a maintenance position.
  • the side seals could, in principle, instead of being positioned laterally of the casting rolls by a manipulator 40, could also be arranged on the frame and be brought with it and the housing 30 into the maintenance position.
  • the housing could also be guided on continuous, non-lowerable rails.
  • the water connection would then have to be made by a plug connection, pressed media plate or the like.
