Definitions

  • the invention relates to a system for the continuous casting of metals and alloys, in particular steels, consisting essentially of at least one or one of the parts or system components: intermediate or distributor vessel, distributor holder, continuous mold, optionally with casters, movable mold carrier , Oscillation device for the mold, casting platform, strand bending device and / or casting arch strand support part (s), strand guide arch parts, strand straightening and strand removal device, strand supports or roller table parts, strand separating device and load-bearing and supporting structural components.
  • the invention relates to a method and procedure for setting up a system for the continuous casting of metals and alloys, in particular steels, consisting essentially of at least one or one of the parts or system components - intermediate or distributor vessel, distributor holder, continuous mold, movable mold carrier, oscillation device for the mold, casting platform, strand bending device and / or casting arch strand support part (s), strand guide arch part (s) as well as structural components supporting and supporting and connecting these parts or components.
  • liquid metal is introduced from a metallurgical vessel or transport container such as a pan and the like into a refractory-lined intermediate or distribution vessel of the system, from which a forwarding or an essentially continuous introduction of the metal through controllable or free-running spouts into at least one cooled mold with open end faces or in a continuous mold.
  • the distributor vessel must be precisely adjustable in or by means of a distributor holder, because the pouring tube or pouring tube and / or the pouring jet must be positioned in the mold with high accuracy, in order to avoid quality disadvantages of the product and / or problems during pouring that occur when incorrectly adjusted .
  • the metal solidifies on cooled side walls to form a solid strand shell, which is drawn off essentially downward with the molten strand core.
  • an oscillating relative movement takes place between the strand and the mold held in a mold carrier.
  • This relative movement between the strand and the mold is achieved in that the mold carrier is moved up and down in a mechanically precise manner.
  • Accurate guidance is particularly important because the surface cooling in the mold, i.e. the so-called primary cooling of the strand, can be effectively improved and homogenized, and strand shell growth can be enlarged and evened out, by a deviation-free oscillation movement.
  • the oscillation device for the mold is mostly supported by the system construction and is often supported on a foundation part to avoid vibrations.
  • the strand emerging from the mold has a thin strand shell, the molten strand core exerting a hydrostatic or metallostatic internal pressure.
  • This internal pressure must be compensated for by precisely aligned casters on the mold and / or by support rollers in order to avoid shell breakthroughs and / or strand cracks.
  • the metal is poured into a curved mold that rotates around the center of the radius of the strand arc or oscillates around it, and is allowed to solidify to form an arc-shaped strand
  • so-called bending systems primary solidification into a straight strand takes place in a straight cylindrical or cuboid mold, which oscillates in a straight line, after which the strand with the liquid core is formed into a circular arc in a bending section or strand bending device.
  • cast sheet strand support parts which are circumferentially closed, i.e. equipped on all sides with support rollers for the thin strand shell, are provided below the mold;
  • a strand straightening and strand withdrawal device, strand supports or roller table parts and a strand separating device are also arranged downstream of the strand guide arc part.
  • the individual parts of the system or system components can, on the one hand, be made up of construction components, e.g. Steel beams or the like, which in turn are anchored in the foundation, and on the other hand are supported or supported by the foundation areas themselves.
  • construction components e.g. Steel beams or the like
  • construction components are first set up, fastened and connected to a supporting structure in a precisely designed foundation.
  • the prefabricated parts or system components are then installed in this construction, their support usually taking place in geometrically adjustable supports on the construction and on the foundation.
  • both the system components and the construction components are exposed to high thermal loads due to the glowing strand, which parts undergo a change in length or elongation depending on the temperature.
  • the expansion of the system components can be taken into account by appropriate storage or displacement or floating bearings arranged on one side, and distortion or bending of the components and / or parts can be avoided.
  • changes in the functional and geometrical alignment or the casting-technical setting of the structural and structural parts can be caused by a different application of heat or a different dimensional change caused thereby Plant arise. Frequent changes in temperature due to the respective castings or casting sequences can also cause misalignments of parts.
  • the invention aims to remedy this, to avoid the disadvantages of known devices and to create an improved system for the continuous casting of metals and alloys, with which the best product quality is achieved with the highest operational reliability. Furthermore, it is an object of the invention to provide a new method or a procedure for setting up a generic device with which the time and adjustment work can be reduced and economic advantages and simplifications can be achieved.
  • the strand draw-off devices are optionally designed as a draw-off straightening device, the roller table parts, the strand cut-off device (s) are anchored directly in the foundation or also of essentially three-dimensional or two-dimensional or planar form Support frames are worn, which support frames are connected to the foundation. If the carrier frame or box frame (s) for the functional parts or system components is (are) three-dimensional, can be assembled and / or installed and, if necessary, can be stacked, an improved internal stability in the individual frame and a particularly constant casting technology setting of the system are achieved.
  • Box frame lines for media and energy supply as well as the measuring, control and control lines for the functional parts or system components and instruments are attached or routed and the lines may have detachable connecting or connecting elements in the area of the frame boundaries.
  • the functional parts or system components - continuous mold, mold carrier with oscillation device, strand bending device and / or at least one casting sheet support part, optionally a casting platform and other functional groups or components are attached to or carried by or in a support frame or box frame and / or are supported, the system components are combined in a favorable manner in the area of the first part of the strand solidification, i.e. in the case of a thin strand shell or with a low strand shell strength and therefore a high risk of defects in the cast strand, which additionally stabilizes the casting technology setting and, as a result, largely assured product quality with maximum operational safety.
  • simple provision and safe, precise and economical erection are also advantageous possible.
  • two or more three-dimensional support frames or box frames each with one or one or more similar functional parts (s) fastened in or on the frame, optionally next to one another, or carried by them or functional group (s) or system component (s) can be placed or aligned side by side to form a multi-line system and, if necessary, connected to one another.
  • a particularly economical system design a so-called module design, is created for multi-line systems.
  • a holding device for the pans is created on or next to the three-dimensional support frames connected to the continuous mold and / or to the intermediate or distribution vessel.
  • a system is particularly advantageously formed by erecting and / or assembling at least one prefabricated three-dimensional support frame or box frame that is easily transportable or can be assembled at short notice, with at least two functional parts or functional groups or system components fastened therein or attached thereto.
  • the advantages achieved with the method and the procedure according to the invention consist, in particular, in that the system attachment and / or assembly segments are manufactured and largely completed in steel construction companies equipped for this purpose if necessary assembled, detachably fastened and functionally geometrically aligned or set in terms of casting technology, after which by loosening the fastening means on the connecting arrangements and / or by attaching lifting arrangements.
  • cradle screws in the three-dimensional support frame or box frame, the segment can be easily lifted and transported to the installation site. All system components as well as measuring, control and media supply parts such as pumps and the like can be installed in frames, thus achieving a perfect segment construction. Test runs, function checks and the like can be carried out and approvals can be carried out on the systems installed in the steel construction company.
  • Fig. 1 shows a casting device for blooms, partly in section schematically.
  • a system according to the invention for the continuous casting of metals and alloys is created on a foundation.
  • the pouring device shown consists essentially of four superimposed and interconnected structural or main segments A, A1, A2, A3, the near-foundation segments A2 and A3 have a greater longitudinal extent and carry secondary segments E, F.
  • Extension segments B, B1 and D, D1 are arranged directly on the foundation C.
  • a continuous mold 2 with casters, a mold carrier 22, an oscillating device 23 and a strand bending device 3 and a casting bow support part 4 are fastened or supported in the support frame of the main segment A.
  • the support frame of segment A1 surrounds a distribution vessel 1 and its holder 11 contains a pouring platform 8 and carries a pouring ladle 9 in a holding device 91.
  • the segments E and F which are likewise formed by box frames, serve as an electrical and control space and as a media space for Cooling water, compressed air, gas, lubricants and the like.
  • cooling water supply devices with pumps, sliders, regulators and the like as well as hydraulic devices are installed, connection elements for the line extension being arranged in the area of the frame boundaries.
  • the secondary segment E includes the electrical power supply for the system with distributor, switch and the like.
  • the support frames essentially support strand guide arc parts 5, 51.
  • a strand straightening take-off device consisting of drive straightening frames 8 and a strand separating device are installed in box frames of the segments B and B1.
  • Roller table parts 7, however, are supported by two-dimensional support frames D, D1.
