Definitions

  • a distribution car with a casting distributor for a multi-strand continuous casting machine for casting long products is known.
  • the distribution trolley can be moved between a casting position and a parking position on the casting platform.
  • the EP 2 574 414 A1 describes a stopper drive, a method for compensating for elasticities or play in the control of the stopper drive and the use of the stopper drive.
  • the EP 0 223 078 A1 describes a method for starting up a continuous caster with several strands, in particular for pouring molten steel from a tundish into several continuous casting molds by means of adjustable pouring closures, whereby a target level of the melt lies within a measuring section of a level measuring device assigned to each mold, and the strands that are formed are drawn off by a strand take-off unit at the same speed.
  • Plug drives are often used in multi-strand continuous casting machines for long products, i.e. products with a billet, bloom or pre-profile cross-section.
  • a stopper drive moves a single stopper so that the stopper can open, close or regulate an outflow of liquid steel from the pouring manifold into a mold.
  • the plug is usually made of refractory material and is exchanged after a distributor change.
  • the casting distributor Before or after the casting operation, the casting distributor is usually transported including the installed plug drives in the so-called distributor economy and for the next casting sequence restored. There is an increased risk of damaging the sensitive plug drives during transport, tipping and storage of the distributor.
  • the object of the invention is to reduce the time required to assemble or disassemble the stopper drives on a pouring manifold.
  • the risk of damage to the plug drives in the distribution industry should be reduced.
  • the risk of injury to the assembly personnel during assembly or disassembly of the plug drives is to be reduced.
  • multi-plug drive In contrast to the prior art, only a single plug drive (called “multi-plug drive”) according to claim 10 - and not, as is customary in the prior art, several separate plug drives - is mounted on the pouring manifold, the multi-plug drive several - i.e. At least two plugs can be opened and closed independently of one another and the individual plug drives of the multi-plug drive are releasably attached to a beam.
  • the assembly time is shortened by the multi-plug drive according to the invention.
  • the pouring manifold is located in the so-called setup area of the continuous caster.
  • the plugs are attached to the individual plug drives.
  • the casting distributor with the multi-stopper drive and the stopper are placed on a distributor carriage, the distributor carriage being in a parking position on the casting platform of the continuous casting machine at this time.
  • the control of the continuous casting machine is preferably via a single cable harness with the Multi-plug drive connected, which in turn reduces assembly time.
  • the pouring manifold e.g. by burner, heated so that the pouring spreader or its lining is not damaged by the subsequent filling with molten steel.
  • the distribution trolley is then moved into the casting position.
  • the distribution trolley is guided by rails on the casting platform.
  • the at least partial filling of the pouring manifold with molten steel can be done in either the parking or pouring position, e.g. directly from a pan or via a so-called pan rotation.
  • At least one outlet channel from the casting manifold is opened by moving (typically lifting) a plug of the multi-plug drive, whereby molten steel flows from the manifold into the mold and the casting operation is started.
  • the multi-plug drive is preferably transported from a storage area to the set-up area before assembly.
  • the transport is preferably carried out by means of a transport manipulator, which can optionally be moved parallel to the casting platform or rotated about an axis that is normal to the casting platform. This allows the multi-plug drive to be safely manipulated. It is particularly preferred if the multi-stopper drive is transported and installed on the pouring spreader by means of one and the same manipulator.
  • the pouring spreader Due to the weight of the pouring spreader, it is useful if the pouring spreader is placed on the spreader trolley by means of a crane.
  • At least one outlet channel from the pouring manifold that is open during the casting operation is closed by moving (typically lowering) a stopper, so that all the plugs of the multi-stopper drive are closed. This ends the casting operation.
  • the pouring spreader is then moved into the park position, where the pouring spreader can cool down, for example by natural convection.
  • the casting distributor is lifted off the distributor carriage.
  • the pouring spreader is then transported to the set-up area of the continuous caster, where the plugs are released from the multi-plug drive. Loosening can take place, for example, by knocking off the plugs.
  • the multi-plug drive is dismantled from the pouring spreader. Due to the weight of the pouring spreader, it is expedient if the lifting of the pouring spreader from the distribution trolley and the transporting of the pouring spreader to the set-up area take place by means of a crane.
  • the multi-stopper drive is dismantled from the pouring spreader using a manipulator.
  • the multi-plug drive is transported to a storage area by means of a manipulator. It is particularly preferred if the dismantling and transporting of the multi-plug drive take place by means of the same manipulator.
  • the several plug drives in a multi-strand continuous casting machine can be quickly mounted or dismantled on the casting manifold.
  • the manipulator is designed to assemble and disassemble the multi-plug drive.
  • the hoist can be designed as a chain hoist arranged on a boom; the traversing device can be formed, for example, by a linear drive, several guide wheels and a rail.
  • the Fig 1 shows a perspective view of a casting distributor 1 on which a multi-plug drive 2 for four strands of a continuous casting machine for the continuous casting of billet strands is mounted.
  • the multi-stopper drive 2 has four stopper drives 3a ... 3d and a common bar 4.
  • the Fig 3 shows that the beam 4 can be hung on an upper bolt 8a of the pouring manifold 1.
  • the multi-plug drive 2 is clamped to the pouring manifold 1 via the clamping unit 7 and the lower bolt 8b, thereby forming a detachable connection between the pouring manifold 1 and the multi-plug drive 2.
  • the plugs 5 of Fig 2 be closed manually by means of the emergency actuation 6.
  • the plugs 5 are detachably connected to the respective plug drive via a screw connection 18.
  • the stopper 5 can open, close or adjust the flow rate by means of the stopper drive 3a... 3d an outlet channel 9 from the casting distributor to the mold, not shown here.
  • the plug 5 closes the outlet channel 9 so that no molten steel can leave the pouring manifold 1.
  • the plugs 5 are made of refractory material and are detachably connected via the screw connection 18 to a plug drive; for example, the plug 5 is off Fig 2 releasably connected to the plug drive 3a.
  • FIGs 4 to 7 the process steps for starting the casting operation of a four-strand continuous casting machine for casting round billets of steel are shown schematically.
  • Fig 4 on the right is a multi-plug drive 2 for four strands, which is located in a storage area 10 on the casting platform of the continuous casting machine.
  • the pouring distributor 1 is shown, which is located in a set-up area 11 of the continuous casting machine.
  • the pouring manifold 1 with the multi-plug drive 2 mounted on it is shown on the far left, the multi-plug drive 2 being detachably connected to the pouring manifold 1 via two clamping units 7.
  • FIG 6 three multi-plug drives 2 are shown in a storage area 10 of the continuous casting machine.
  • One stopper drive 2 is transported by means of a manipulator 15 from the storage area 10 to the set-up area 11, and there it is lowered onto the pouring manifold 1 via the lift 17 of the manipulator 15 and mounted thereon.
  • the lowering of the multi-plug drive 2 by means of the hoist 17 is shown in FIG Fig 5 shown.
  • the manipulator 15 can be moved parallel to the casting platform 16 via rails 13.
  • the directions of travel the manipulator 15 and the hoist 17 are shown by arrows.
  • the plugs 5 attached to the multi-plug drive 2 are also shown.
  • the stopper 5 is connected to a stopper drive via a screw connection 18 (see also Fig 2 ).
  • the placing of the pouring distributor 1 on the distributor carriage 12 by a crane is not shown separately. Also not shown are the establishment of electrical connections between the control of the continuous casting machine and the multi-plug drive 2, the heating of the pouring manifold 1 via burners and the filling of the pouring manifold 1 with liquid steel, for example via a ladle turret.
  • Fig 7 the distribution carriage 12 with the casting manifold 1 mounted thereon is drawn through in the parking position and shown in dashed lines in the casting position.
  • the movement of the distribution truck 12 on rails 13 is again symbolized by an arrow.
  • the molds 14a ... 14d of the multi-strand continuous casting machine 100 are shown.
  • FIG Fig 2 The opening of a plug 5 of the multi-plug drive 2 is shown in FIG Fig 2 shown. This starts the casting operation of the multi-strand continuous casting machine.
  • FIG 8 an embodiment of a multi-strand continuous casting machine 100 according to the invention is shown.
  • the depositing area 10 for the multi-plug drive 2 and the setup area 11 for the pouring manifold are located on the casting platform, which is not shown separately 1.
  • the multi-stopper drive 2 is lifted from the storage area 10 by means of the manipulator 15 and the hoist pull 17, transported to the set-up area 11 and there placed on the pouring manifold and mounted.
  • the manipulator can be moved on the rails 13 by the movement drive 15a.
  • the pouring spreader 1 with the multi-plug drive 2 is then lifted off the set-up area 11 by means of the crane 19, which is designed as an indoor crane, and placed on the spreader carriage 12.
  • the distribution trolley 12 can then be moved on further rails 13 from the parking position into the pouring position shown in dashed lines.
  • the indoor crane has a trolley 20 so that the crane can be moved from left to right over the trolley 20 and from top to bottom over the rails 13 arranged on the side in the casting hall, as shown.
