Definitions

  • the invention relates to a device for vertical, discontinuous continuous casting of metals, in particular steel, into blocks of several meters in length, with a continuous casting mold which can be closed by means of a base plate and with a beet-lowering device which supports the base plate.
  • metals that are not susceptible to cracking are largely cast in continuous sheet casting machines and / or in vertical bending machines, the metal bearing the stress during the passage through the bending sections or during the cooling process and during the subsequent reverse bending process in a largely solidified state.
  • Such block strands are now to be made of extremely bending-sensitive materials, such as very high alloy steel grades are manufactured at low casting speeds, e.g. lying below 1 m / min.
  • the invention is based on the call to treat such continuous casting blocks as gently as possible after leaving the continuous casting mold and only to subject them to bending stress from a certain cooling state.
  • the bending stress should be practically excluded during the beet lowering and during a cooling phase, i.e. the continuous casting block should be in an absolutely vertical position, starting in the continuous casting mold, on an absolutely vertically movable support over the entire casting time, so that no stress (except pressure) is taken over its cross section have to.
  • the object is achieved in that a cooling zone is arranged under the continuous casting mold, which has internally cooled cooling elements, and that the length of the continuous casting mold together with the length of the cooling zone is not more than 2500 mm.
  • the continuous casting stock is treated gently during production, so that no material damage can occur and a high surface quality is achieved. This also prevents chilling cooling and counteracts the dangerous bulging with a thicker shell.
  • the beet lowering device in its lowermost position is opposite a manipulation device running vertically with its longitudinal axis parallel to a guide column, which underpins a separate base plate and encloses the cast strand by means of a pliers-like gripper approximately at its center of gravity.
  • Advantages of this solution are an absolutely vertical casting due to the separate base plate and an extremely gentle treatment of the continuous casting block after it has been cast.
  • the parallelism between the guide column and the manipulation device allows bending-free support even during the takeover, i.e. during the removal of the continuous casting block from the continuous vein in order to clear it for a new continuous casting. It should be noted that the continuous casting block has in no way cooled sufficiently during this time, but that considerable structural damage could still occur in this phase.
  • the continuous casting block is now transported in the standing position in order to avoid any bending stresses even now.
  • the invention provides that the manipulation device is pivotable about a vertical axis, has a rotary bearing and a rotary drive.
  • the Russian conveyor device has a carriage that can be raised and lowered in the transfer position.
  • the trolley can take advantage of the continuous cast block, which is important for weights of 20, 30 and more tons.
  • the handover of the continuous casting block requires a favorable support over its length.
  • Such support is achieved by providing a support device with a plurality of support bearings on the carriage, which extends in the longitudinal direction of the cast strand.
  • a manipulation device with a soot conveyor device is axially symmetrical about a lifting frame which is equipped for two cast strands. Accordingly, two cast strands can be cast simultaneously.
  • Measures are also provided below to treat the sensitive cast strand advantageously in terms of heat or cooling technology.
  • the continuous casting mold or continuous casting mold and manipulation device with the conveying device between each strand strand and the manipulation device, one or more cooling chambers provided with lateral, closable openings are provided.
  • Each continuous casting block can therefore be cooled more quickly than would be possible by natural cooling, but can nevertheless be cooled in a controlled manner without the casting structure being damaged.
  • the casting end is particularly taken into account by assigning an induction coil to one or more of the cooling chambers in the head region of a casting strand, which is used for controlled cooling of the casting strand along the length of the casting head.
  • a further influence on the solidification of the cast continuous casting block is that inlets and / or channels for cooling media are provided in the walls of the cooling chambers and that control valves are provided upstream for controlled cooling of the casting strand. It is also possible to open the top of the cooling chamber to extract hot air and supply it to a heat recovery system.
  • the continuous casting mold (1) is arranged on the casting platform (2). Below the continuous casting mold (1) there is a cooling zone (3) closed off from the outside with supporting elements (3a) which support the continuous casting block without great resistance to bellies. At the same time, the internally cooled support elements (3a), which e.g. consist of internally cooled rollers or support plates, the cast strand (9) has sufficient heat without being put off, so that a sufficiently thick strand shell is quickly formed.
  • the internally cooled support elements (3a) which e.g. consist of internally cooled rollers or support plates, the cast strand (9) has sufficient heat without being put off, so that a sufficiently thick strand shell is quickly formed.
  • the continuous casting mold (1) is closed with a base plate (4) before the start of the casting, direct contact with the liquid metal, e.g. high-alloy steel, avoided by insulating material.
  • the metal melt is then poured from a storage vessel into the continuous casting mold (1).
  • the base plate (4) which is based on a stamp (22)
  • the stamp drive (23) is continuously lowered by means of a stamp drive (23) until the stamp stroke has been completed.
  • the beet lowering device (5) takes over at the casting speed, e.g. 0.4 m / min the further lowering of the cast strand (9).
  • An induction coil (not shown further) can also be arranged within the continuous casting mold (1) in order to make oscillation of the continuous casting mold (1) unnecessary. However, the continuous casting mold (1) can still be oscillated.
  • the beet lowering device (5) moves exactly vertically on the longitudinal axis (6) of a guide column (7) and thus parallel to a likewise vertically arranged manipulation device (8) which has a rotating arm (8a) and a gripper (10).
  • a soot conveying device (14) is arranged on the side facing away from the cast strand (9), namely at a distance that a transfer position (15) results, in which the cast strand (9) is moved from the manipulation device (8) by pivoting onto the soot conveying device (14) is handed over.
  • the Rus infectionvoroplasty (14) consists essentially of a carriage (16) to which a support device (17) is attached, which extends parallel to the axis (11).
  • the support device (17) forms a plurality of support bearings (18) for the cast strand (9).
  • the lowering device (5) consists of a lifting frame (19) which carries the punch (22) and the punch drive (23) and a drive (21) for height adjustment.
  • the guide for the lifting frame (19) forms the large-diameter guide column (7) and the drive (21) is supported on a threaded spindle (28) which can also consist of a toothed rack or the like.
  • the threaded spindle (28) can be multi-start. Call of the threaded spindle (28) a correspondingly multi-start threaded nut (29) slides with the drive (21).
  • the plunger (22) is always only moved to a stand (30) in order to allow the rotating arm (8a) to pivot in.
  • the lifting frame (19) stands below the manipulation device (8) and supports with the stamp (22) or with the base plate (4) the cast strand (9), which still has a liquid sump in its interior, which can be up to about 10 meters long with a 14 meter long cast strand (9) .
  • the cast strand (9) fixed in position by the gripper (10) is then embraced by the rotating arm (8a) below the base plate (4) and taken over by the rotating arm (8a) after a short lowering of the lowering device (5).
  • the gripper (10), the rotary arm (8a) and thus the manipulation device (8) are rotated in the rotary bearing (12) around the axis (11) by means of the rotary drive (13) parallel to the longitudinal axis (6) of the beet lowering device (5) and in the position of the cooling chamber (20a, 20b, 20c, etc.) assigned to the cast strand (9) is pivoted (FIG. 2).
  • the die head (9b) is kept at a temperature by means of the induction coil (24) which corresponds to the mean temperature of the cast strand (9).
  • the cast strand (9) is removed from the respective cooling chamber (20a to 20f) by means of the manipulation device (8) and fed to a conveying device (14).
  • the carriage (16) of the Russian conveyor device (14) is raised until it has taken on the load of the cast strand (9).
  • the gripper (10) and the rotating arm (8a) of the manipulation device (8) are then rotated until the conveying of the cast strand (9) in question can be carried out.
  • the cast strand (9) is supported on the support device (17) and on the support bearings (18) located thereon.
  • the cast strand (9) conveyed out is then fed to the cutting device mentioned.
