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, each with a jacket width, on which end seals are arranged on the front side, rotatably mounted on a machine stand and driven by at least one motor, the between these casting rolls and the side seals are protected from at least one gaseous medium by at least one pouring tube or the like fillable metal melt.
- a box-shaped container is provided for sealing the solidified metal strip emerging between the casting rolls, the wall of which extends to the lower outer jacket of the respective casting roll, and a seal is generated by a sealing element.
- a seal is relatively complex both in terms of construction and in terms of maintenance and causes undesired contact of the sealing element with the rotating casting roller. If there are any leaks, there is a risk that the metal strip will develop a scale that reduces its quality.
- the present invention was based on the object of creating a strip casting machine of the type mentioned at the outset, with which a perfect seal against the ambient air both of the metal bath or of the metal strip produced and of the casting rolls and furthermore simplified operation and maintenance of the machine is made possible ,
- the object is achieved according to the invention in that at least the casting rolls at least in each case over their jacket width and end faces and the side seals are surrounded by a preferably multi-part housing.
- the casters and side seals can still be made quickly and easily accessible for servicing and maintenance, which can increase the operating performance of this machine.
- a longitudinal housing with a chamber adjoins the housing for the metal strip emerging below these casting rolls through the casting gap formed, the chamber formed by the housing being connected through an opening to the subsequent chamber of the longitudinal housing.
- FIG. 1 shows a schematic longitudinal section through a strip casting machine according to the invention
- FIG. 2 shows a cross section of a housing through the axes of the casting rolls of a strip casting machine according to the invention
- FIG. 4 shows a schematic view of a further variant of a strip casting machine.
- FIG. 1 shows a strip casting machine 20 of a metal strip 15 that can be produced in a continuous casting process, in particular one Steel strip.
- This band casting machine 20 stands on a stage 12 and is supplied with molten metal 16 by a distributor vessel 18 above it, as is known in conventional continuous casting plants.
- the distributor vessel 18 expediently has a pouring opening 17 which can be closed with a stopper 19 or the like and has a pouring tube 13 which extends between the casting rollers 22, 24 and through which the melt can flow off.
- 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 each provided with a side seal 25 on both end faces, whereby an all-round opening 26 with a downwardly open casting gap 15 'is formed ,
- the casting rolls 22, 24 are rotatably supported on both sides on an indicated machine stand 32 and driven by a motor integrated therein.
- the casting rolls 22, 24 are surrounded by a closable housing 30, which has an opening 30 'on its upper side for the casting tube 13 extending between the casting rolls 22, 24 and an opening 30' 'for the emerging metal strip 15 on the underside , these openings 30 ', 30 "being sealed and the chamber 33 in the housing being filled with a protective gas, preferably an inert gas, during casting.
- a protective gas preferably an inert gas
- This box-shaped housing 30 is very advantageously arranged both laterally and at the top at a distance from the casting rollers 22, 24 or from the machine stand 32, so that no sealing elements shielding against the outside need be provided, as is the case for example is required for the casting machine according to EP-A-0 780 177 mentioned at the beginning.
- this housing 30 is provided with two horizontally lying doors 35, which are designed in such a way that they can be moved from the closed position shown in FIG. 1 to a horizontally pushed position. For this purpose, they are guided laterally in corresponding rails (not illustrated), wherein they are advantageously lowered into the closed position shown 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 are manipulated by a manipulator 40, which can be moved outside the housing 30, from the operating position shown through these openings 39 can be guided out of or into the housing 30.
- the respective manipulator 40 has a holding arm 41 and a drive 42 that can be adjusted in height. It can be moved from an operating position to a retracted maintenance position and vice versa 40, a seal of the non-closed opening 39 can be brought about by means of a separate protective cover 38, this protective cover 38 enclosing the manipulator 40 and accordingly striking laterally against the housing 30.
- cassettes 88 for the introduction and removal of side seals 25 are also indicated.
- the cast metal strip 15 is guided below the housing 30 into an additional longitudinal housing 44, which forms a chamber 45, in which a protective gas is also contained, in order to prevent the metal strip 15 from coming into contact with oxygen and thus in particular to protect scale formation.
- a plurality of rollers 46 and press rollers 47 are arranged in this chamber 44, so that the metal strip 15 is guided through this longitudinal housing 44 and through an opening 48 sealed in it. After exiting from this housing 44, this metal strip, which has cooled until then, can, for example, be rolled up or otherwise processed.
- the longitudinal housing 44 has a depression 49 below the opening 30 ′′ or the casting gap 15 ′, in which there is a collecting container 52 placed in a system base 51.
- This collecting container 52 has the task of removing the bottom from the casting rolls in the event of a leak to catch emerging liquid melt without causing any damage above this container 52 there are still pivotable guide flaps 54, 55 which form a passage * in the position shown, but in the dot-dash pivot position 54 ', 55' as a guideway for the metal strip 15 serve.
- the upper opening 30 'in the housing 30 is sealed by a bellows 11 or the like which connects the vessel 18 to it, this sleeve-shaped bellows 11 enclosing the pouring tube 13.
- the pouring tube could also be omitted and a freewheel could be provided.
- the lower opening 30 ′′ of the housing, through which the band 15 passes, can be sealed, for example, as a sealing device by a gas screen produced by nozzles 34. In principle, however, this sealing device could be omitted and the opening 30 ′′ thus open continuously into the chamber 45.
- the housing 30 has a feed line (not shown in more detail) for blowing protective gas into the interior 33. Shielding gas can also be passed additionally into the distributor vessel 18 provided with a lid. The gas introduced into the housing 30 can be cooled and returned through 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.
- Fig. 2 and Fig. 3 show in principle a variant of a strip casting machine, which is designed in itself the same as that of Fig. 1.
- a housing 60 is provided, in which, according to the invention, the casting rollers 22, 24 are surrounded by the multi-part housing 60 over their jacket width and end faces, as well as the side seals 62, but not the motor stand 61 which supports the axes 64 of the casting rollers 22, 24.
- This housing 60 encloses the axes and also the drive 66 of the seals 62 on both sides of the casting rolls. On the upper side it is spaced apart from the indicated melt container 18.
- the multi-part housing 60 is provided with a base foot 67 which can be fastened to this longitudinal housing via a fastening member 69.
- the longitudinal housing 65 is advantageously closed all around and only has a sealed outlet for the cast metal strip 15.
- 4 shows a strip casting machine according to the invention, again with two casting rolls 22, 24, which are contained in a housing 80.
- This housing 80 consists of a double-walled side wall 81 and a cover 82 which is held so that it can be lifted off, as is indicated by the lifted off cover 82 '.
- the housing 80 surrounds the casting rollers 22, 24 and the side seals 83.
- the housing has an opening 84 at the bottom, which opens into the chamber 85 ′ of a longitudinal housing 85.
- This housing 80 is positioned in a frame 88 which has wheels 87 which are guided on rails 89.
- both the housing 80 and the longitudinal housing 85 are advantageously water-cooled so that they do not heat up excessively over the course of the operating time.
