Definitions
- the invention relates to a device for transporting ladles to a continuous casting installation, consisting of a lifting device for lifting the ladles coming from the steel mill from a means of transport and lifting to the level of the casting position, and a rotating tower arranged at the level of the casting platform, which picks up and closes the ladles raised in a ladle changing station the casting station moves.
- the device for transporting ladles to a continuous caster thus generally consists of a wagon that can be moved on the hut floor, a hall crane or trolley crane and a ladle wagon or ladle turret arranged at the level of the casting platform.
- This device for transporting the liquid steel to the continuous caster is expensive because high halls with expensive hall cranes are necessary.
- the invention is therefore based on the object of making the device for transporting ladles cheaper, in order thereby to make continuous casting more economical.
- this object is achieved in that the lifting device for the ladles is provided directly on the turret and can be pivoted with the same from a position covering the ladle changing station into the position directed towards the casting station.
- a particularly advantageous application of the invention results if, when using a rotating tower having at least one support arm, the hoist provided with a winch is fastened directly to the support arm, over the outer ends of which support cables are guided, which are provided with suspension devices for the pan.
- a two-armed rotating tower, which carries a winch on each support arm, is usually used.
- a pouring jet protection for example a pouring tube; is available; the ability to raise and lower the ladle during casting using the hoist is an additional advantage.
- a pouring jet protection for example a pouring tube; is available; the ability to raise and lower the ladle during casting using the hoist is an additional advantage.
- both supporting arms of the same are connected in a straight and rigid manner, and that the lifting device can be moved between the outer ends of the two supporting arms and each end of the supporting arms with a carrying device for each a pan is equipped. With this device, a single hoist is sufficient for the two support arms of the rotating tower.
- the support device for the pan is arranged to be pivotable about a vertical axis and supports the support pins of the pan in the carrying position.
- Another advantage of the ladle support device according to the invention is the lifting and replacement of emergency pans, overflow channels, etc., which are generally installed in the range of motion of the turret between the casting station and the ladle changing station.
- a continuous steel casting plant for billets, blooms or slabs is often made as shown in Fig. 1.
- the liquid steel coming from the steelworks is supplied in hall A, and the continuous casting machine 1 is located in hall B.
- a mold 11 is arranged on a casting platform 3 below an intermediate vessel 13. With 1 "a roller strand guide is shown
- the device for transporting ladles 2, 2 'from the steelworks to the ladle changing station 6 of the continuous casting plant consists of a carriage 20 which can be moved on the floor of a hut.
- a ladle turning tower 33 is used.
- This ladle turret 33 essentially consists of two support arms 31, 32 which are connected to one another and rotatable about a vertical axis 34.
- One support arm 31 of the turret 33 is located in the casting station 7 above the intermediate vessel 13 in hall B and the other support arm 32 in the pan change station 6 in hall A.
- empty pans are exchanged for full pans
- the pan 2 ' With a hoist 4; the pan 2 'can be raised directly on the turret 33 and is movable with it.
- a broken roof line is shown above the solid roof line for halls A, B; which would result if a crane was installed in these halls A and B according to the state of the art.
- each support arm 31, 32 is equipped with its own lifting device, which e.g. consists of a winch 41 for a cable 42, equipped.
- the cable 42 is guided over the deflection roller 35, which is placed at the extreme end of the support arm 31.
- the pans 2, 2 ' are attached via suspension devices 45 in the form of support hooks.
- the two winches 41 are equipped with separate control devices.
- Protective shields 46 are attached to protect against thermal radiation. When the pans have reached their highest position, the hoists can be blocked.
- the installation costs can be further reduced if only a single lifting device 43, as shown in a further embodiment in FIGS. 4 and 5, is used.
- the lifting device 43 is mounted on a movable carriage 40, which can move on rails 34 on the top of the straight and rigidly connected support arms 31 and 32 (FIG. 2).
- the hoist 43 can thus move from the end of one support arm 31 or 32 to the end of the other support arm 32 or 31.
- the support arms 31; 32 can be equipped with support devices 56 for each pan 2 in order to clear the lifting device 43.
- Each support arm 31, 32 of the turret is provided with fork-shaped recesses at its outer ends, as usual. Between these recesses, the support devices 56 for the pan are attached to two brackets 60.
- brackets 60 can be rigidly attached.
- the carriage 40 is moved to the extreme end of the support arm 31. Then the pan 2 is raised so far that its support pins 21 are at a higher level than the support device 56 and then move the carriage until the support pins 21 are located exactly above the support device 56, whereupon the pan 2 can then be placed on it .
- the bracket 60 can be arranged to be pivoted away about a vertical axis 61, as shown in FIG. 5.
- the movable carriage is placed so that the axis of the support pins 21 is located centrally above the support device 56.
- the brackets 60 are in the pivoted-away position, which allows the trunnions 21 to pass through.
- the pan is raised so far that its support pins 21 lie a little above the support devices 56.
- the brackets 60 are then pivoted into the support position below the support pins 21 so that they can be supported on the support devices 56.
