Definitions

the invention relates to a device for the horizontal continuous casting of metals according to the preamble of claim 1.
Such a device is known in principle from DAS 12 92 791.
the pivot axis is arranged in the plane between the drive rollers, so that the device on the pouring side can be raised towards the end of the casting in order to maintain the necessary metallostatic pressure in the mold when the casting level drops.
a device for the horizontal continuous casting of metals in which a separation of the distributor and the mold is achieved by shut-off devices which close the distributor outlet opening and at the same time close the mold inlet at the end of casting or a fault. Since the distributor and the mold can be separated from one another between the shut-off devices, the distributor can be emptied with the residual melt, including any slag, by tipping over at the end of pouring or in the event of a malfunction, without having to wait for the solidification of the melt in the mold.
DE 27 10 680 C2 discloses a device for casting strands, in particular precious metals, which makes it possible to work in the holding furnace or the mold without residue from the melt.
the holding furnace, a cooler with mold and the extrusion device are arranged on a common frame that can be swiveled up to 180 °.
the cooler and the mold are attached to a holding device that can be folded away from the holding furnace.
the invention is therefore based on the object of developing a device according to the preamble of claim 1 and of improving and simplifying the accessibility of the system in the event of faults.
the object is achieved according to the invention in a device for the horizontal continuous casting of metals, consisting of a pouring device, a mold and a strand transport device, which are arranged on a bridge construction which can be pivoted about a horizontal axis lying transversely to the casting direction, in that the axis forming the pivot point is arranged below the pouring opening designed as a holding furnace inside the bridge construction and the holding furnace, the mold with a possibly subsequent secondary cooling section and the strand transport device can be swung out in the vertical direction from the casting position in the vertical direction by means of a hydraulic cylinder acting on the free end of the bridge construction in the casting direction in front of the axis .
the drawing shows a device for the horizontal continuous casting of metals in a side view.
the device consists of a holding furnace 1, to the side of which a horizontal mold 2 is connected and which is followed by a secondary cooling section 3. As seen in the casting direction, another follows Strand transport device 4 with two pairs of drive rollers 5.
the holding furnace 1, the mold 2, the secondary cooling section 3 and the strand transport device 4 are arranged according to the invention on a common bridge construction 6.
a strand 7 produced in this device can be divided into strand sections in a subsequent separating device 8, which, depending on the strand format, is designed as a saw or scissors.
the strand sections are picked up by a roller table 9 and transported further.
the bridge structure 6 is pivotally mounted about the axis 10 placed under the holding furnace 1. From the casting position shown in the drawing, the device (1 to 4) including the bridge structure 6 is actuated in a vertical direction from the casting position by actuating a hydraulic cylinder 11, which engages at the free end of the bridge structure 6 in the casting direction in front of the axis 10 at the articulation point 12 swing out at the top.
the hydraulic cylinder 11 is fastened with its foot end 14 to a supporting frame 13 on which the bridge structure 6 rests during the casting process.
the support frame 13, the separating device 8 and the roller table 9 are attached to a plate 15.
the advantages of the device according to the invention lie on the one hand in the very compact design and on the other hand in the fact that the regular separating device for the strand can also be used as an emergency separating device in order to bring about an immediate disconnection of the strand and pivot the pouring device for emergency emptying via the holding oven, so that damage to the molds is avoided. This advantage is particularly noticeable in the very expensive tubular molds.
