Definitions

  • the present invention further relates to a cast-rolling composite plant having a subordinate plant part with a continuous casting plant for continuously casting a metal strand, a downstream plant part with a multi-stand rolling mill and between the two plant parts a pair of scissors for dividing the metal strand into pieces.
  • the production of a cast-rolled composite plant is often carried out in continuous operation, wherein the continuously cast and withdrawn from the casting mold metal strand fed directly from the casting heat out of a rolling train and there to a metal strip - in individual cases as an alternative to heavy plate - rolled becomes.
  • the rolling train are usually arranged downstream of a cooling section and / or a reel assembly with at least one reel.
  • unplanned problems may occur at the casting plant, such as e.g. tearing and re-healing of the strand shell forming in the mold, resulting in a deteriorated portion in the metal strand which is to be precipitated without causing cast-breakage.
  • the scissors can be designed, for example, as a drum scissors, as pendulum scissors or as a crank scissors depending on the requirements of the cutting force.
  • the scissors is often used in the event of an interruption of continuous operation as a crop shear for separating the tape end.
  • the pieces of the metal strip fall in known systems after separation on a directly below the scissors arranged metal chute. Over the metal chute slide the pieces - usually transverse to the main conveying direction - until they fall into a receptacle (junk bucket).
  • a receptacle junction bucket
  • the receptacle if it is accessible from above, can be lifted and emptied as needed by means of a crane. Is the receptacle due to structural circumstances of the casting-rolling compound from above not accessible, a transport of the receptacle transverse to the main conveying direction is required until it can be reached from above by means of a crane.
  • the scissors are due to the applied by her cutting performance very solid and therefore very heavy. Due to the high weight, the forces that occur and the vibrations that occur, large, stable foundations under the scissor stand are required. Since the metal chute is located in conventional systems directly below the scissors and thus also below the foundations of the scissor stand, the metal chute must usually be mounted deep below the scissors to ensure a sufficiently high and thus stable support for the scissors foundation. Furthermore, due to the high coefficient of friction of the separated, often hot metal pieces a steep slide is required. Overall, this results in a large height of the system.
  • the separated from the scissors pieces usually have a relatively high weight, usually several tons, for example 2 tons to 7 tons. If such heavy pieces are fed over a significant drop height to the receptacle, it comes to very high impact loads. These stresses can cause damage to the metal chute and the foundations of the metal chute and receptacle. Furthermore, it is possible for the pieces to tilt and get stuck while sliding on the metal chute. The same danger exists in the receptacle. All of these factors affect the depth of the receptacle and increase the cost of foundation structures.
  • the amount of metal strip cut into pieces by means of scissors and subsequently discharged into a scrap container (also referred to as "scraping") is maintained to maintain a continuous casting operation can, through that Capacity of the scrap container or metal chute limited.
  • From the US 4 106 549 A is a device for the removal of separated pieces of a metal strand transverse to the production direction, in particular for separating tape ends - also known as "tamping" - known (see column 1 lines 7 and 34/35, column 2 lines 43 and 59), especially for slabs - and billets (see column 1 lines 12, 13) in continuous casting.
  • the separated piece of a pivotable roller table section which is designed by a lever mechanism transversely to the main conveying direction of the metal strand tilted, transferred to a scrap container.
  • the energy consumption of the rolling train or one of the rolling mill upstream heating device can be reduced. Furthermore, energy losses due to the Stefan-Boltzmann radiation law in those areas of the plant are greatest, in which the metal strand has the largest surface temperature: it is therefore anxious to make the equipment immediately behind the caster for energy reasons as short as possible.
  • the discharge device In the case of prolonged production stoppage on such a cast-rolling composite plant, in which the continuous casting operation can no longer or should no longer be maintained, the discharge device must be able to handle the amount of metal in the distribution trough, in the mold and in the plant parts as far as the scissors, to prevent the solidification of the cast metal strand in the pouring arc of the strand guide.
  • the generic operating method and the associated casting-rolling composite system are from the WO 2009/121 678 A1 known, wherein in the event of a production interruption by means of a pair of scissors, the metal strand is separated, the rolling-line-side part of the metal strand raised and the strand guide side, continuously nachge felicitte part of the metal strand is shredded by means of the scissors and the pieces on a lowerable roller table 18 in the main conveying direction accordingly FIG. 2 , or in addition, in the presence of a second scissors, which allows the separation of longer pieces of the order of 8 to 14m, by means of a Aus cakevorrichung 8 transversely to the main conveying direction accordingly FIG. 3 and FIG. 4 be discharged.
  • FIG. 4 omitted and it is both the length in the main conveying direction between the scissors and the downstream rolling stand and the height below the scissors to be reduced.
  • the cast-rolling composite system can be produced more cheaply.
  • the at least three receptacles is always a receptacle immediately before the conveyor in a so-called collection position for receiving the conveyed from the conveyor pieces, while at least another emptied receptacle is in a Einhebeposition the collection station and at least one further, usually at least partially filled Receptacle is transported as quickly as possible from a lifting position of the collecting station.
  • the conveyor is located below a fixed, the scissors downstream roller table section.
  • the conveyor can be directed obliquely downwards.
  • the inclination of the conveyor may be so large that the pieces are fed to the collecting station by their weight.
  • the conveyor may alternatively have rollers or be designed as a slide. In the case of roles, a slight inclination of the conveyor is sufficient. In the case of a slide, the slope must be greater to overcome the static friction and sliding friction. In the case of feeding the pieces by their weight, no drive is required for the conveyor.
  • the conveyor is directed horizontally or only slightly obliquely.
  • the pieces are fed to the collecting station by means of a driven conveyor.
  • the pieces can be fed to the collecting station with a defined speed and defined orientation, so that they can be stacked ("finished") in a space-saving manner.
  • the drive of the transport device can be designed, for example, as an electric motor or as a hydraulic drive - in particular as a hydraulic cylinder unit.
  • the scissors is preceded by at least one further rolling stand - sometimes more than one further rolling stand - in the form of a rough rolling line, which pre-rolls the cast metal strand into a pre-strip.
  • the casting heat still contained in the material can be used to a first reduction in thickness, which allows an energetically favorable operation of the casting-rolling composite system.
  • a receptacle which is located in the collecting station in a directly adjacent to the receiving position removal position, as quickly as possible, for example by moving or by crane removal removed and emptied receptacle as soon as possible into a waiting position of the collection station.
  • This allows a quick and smooth change of the receptacle. Since the collecting station is located laterally of the cast-rolling composite plant, this rolling of the receptacle is preferably parallel to the production operation of the cast-rolling composite plant, especially during the deposition of material from the cast-rolling composite plant in the collection station, which is a swift Operation of the casting-rolling composite system with only a few interruptions allows and therefore is economically favorable.
  • the cast-rolling composite plant is operated so that on the one hand the cutting times of the scissors, the movements of the transport device - if any - are synchronized for conveying the pieces into the collecting station and the movements for positioning the receptacles in the collecting station, so that at any time An unplanned plant failure or a planned production interruption may occur without a cast-iron demolition must be brought about and without any excreted pieces in the conveyor jam or fall between the receptacle.
  • This can be achieved, for example, by virtue of the fact that the cast-rolling composite installation or the units of the cast-rolled composite installation necessary for this purpose are connected to an automation device. Moving a full container from the collection position to the picking position typically requires about fifteen seconds.
  • the cutting sequence of the scissors may be in a time range shorter than the period for changing the receptacles in the collecting station, for example 4 to 5 seconds. If material now has to be removed, for example because a sudden disturbance occurs in the cast-rolled composite plant or because a qualitatively inferior section of the metal strand is to be precipitated or because a work roll is to be changed in the subsequent rolling mill, an attempt is made to maintain the continuous casting operation. for example, by reducing the casting speed to a minimum.
  • the thickness reduction can be temporarily suspended in a possibly existing roughing stand: both measures lead To a reduced speed of the metal strand or the Vorbandes on the scissors, so that the time between two cuts of the scissors increases significantly, for example, to 60 seconds. At this reduced speed, therefore, a container change in the collection station can be easily performed, but due to the inertia of the control cycles of the individual trades, a corresponding period of time is to schedule until the reduced speed of the produced metal strand is reached on the scissors. It is therefore an object to take this circumstance into account and to carry out a change of the receptacles only if either no material is eliminated or if the production speed permits this.
  • the pieces separated from the scissors have a length which is between 2 m and 4 m. These lengths have proven to be particularly easy to handle.
  • the angle by which the pivotable roller table section is pivoted down is in a range between 10 ° and 40 °, preferably in a range between 20 ° and 30 °.
  • This angular range allows on the one hand the controlled transport of the separated pieces by means of the usually driven rollers of the pivotable roller table section to the conveyor, so there is no slipping or tilting of the pieces and no damage to the conveyor comes.
  • the inclination of the pivotable roller table section is sufficiently large to achieve the necessary depth of the conveyor below the fixed roller table section of the scissors downstream roller table at a sufficiently short length in the production direction, so limited in normal operation, the radiation losses of the metal strand, which is advantageous to the energy consumption of the cast-rolling composite plant.
  • the advantageous embodiments of the metallurgical system correspond substantially with the advantageous embodiments of the operating method.
  • the collecting station is dimensioned such that it has a capacity which corresponds to at least one filling of the distribution trough of the continuous casting plant plus the amount of metal, which is located in the continuous casting mold and between the continuous casting mold and the scissors. This ensures that even in the worst case and thus regardless of the time of an unplanned production interruption at any time pouring can be continued until the entire amount of metal in the tundish is poured and the continuous casting mold and the strand guide are emptied.
  • the capacity of the at least three receptacles of the collecting station taken separately in each case, preferably corresponds to less than the filling of the distributor trough plus the amount of metal which is located in the continuous casting mold and between the continuous casting mold and the shears.
  • the drives of the receptacle of the collecting station drives which can be operated by remote control technology.
  • the receptacle can be configured automatically driving, so that no operator must go to the danger zone of the collecting station for moving the receptacle within the collection station.
  • the scissors a possibly existing transport device for feeding the separated pieces in the collecting station and the drives of the receptacle with a automation device are connected by remote control technology.
  • This automation device can, for example, the Cutting time of the scissors, optimize the movements of the optionally existing transport device and the process of receiving containers in the collection station in time, which has a favorable effect on the production speed of the cast-rolling composite system.
  • the automation device can, for example, control and synchronize the movements of said units in such a way that the remaining capacity of the receptacle in the collection position is sufficient at any time to be able to pick up the discharged pieces at maximum production speed of the metal strand when the pieces are separated by the scissors until the production speed of the cast-rolling composite plant is reduced so that the time between two cuts of the scissors sufficient to move the receptacle from the collection position to the removal position and nach spallördern an empty receptacle to the collection position.
  • the receptacle of the collecting station are horizontally movable on rails.
  • a rapid displacement of the receptacle, in particular of filled with several tons of scrap receptacles accomplish, since in the case of rails, the drive energy is essentially needed only to overcome the inertia, while adhesion resistance and rolling resistance play only a minor role.
