Definitions

  • the invention relates to a mold unit for the continuous casting of metal products, in particular for the continuous casting of blooms.
  • the invention also relates to a continuous caster.
  • liquid steel is poured from a ladle into a distributor and then vertically through a pouring pipe into a water-cooled (copper) mold.
  • Chill molds can have different shapes, whereby, for example, slab, bloom, billet and profile strands can be produced.
  • the strand When passing through the mold, an already solid strand shell forms on the (copper) walls of the mold, while a core of the strand is still liquid. Subsequently to the mold, the strand, which continues to solidify, is drawn off by guide and drive rollers and brought into a horizontal position. The strand is cooled further with water nozzles. After complete solidification, the strand is cut into pieces of the desired length at the end of the casting plant.
  • Plate molds comprise several separate mold plates which contact one another and which together form a casting mold with a polygonal, in particular rectangular, cross-sectional shape.
  • a plate mold has a mold plates that its mold plates can be stored in such a way that a distance between opposing mold plates can be adjusted so that metal products of different formats can be cast with the plate mold.
  • Another advantage of a plate mold is that the mold plates, which are still thick at the beginning of a mold travel, can be reworked again and again in order to compensate for the wear caused by the strand on the inside of the mold plates, and that damaged or worn mold plates can be reworked or replaced in a targeted manner.
  • the plate mold has to be dismantled again and again and screwed back exactly after processing.
  • tubular molds have mainly been used for the continuous casting of small-sized metal products, i.e. H. Casting formats below 240 mm are used.
  • plate molds have usually been used up to now.
  • tubular molds have recently been increasingly used, since with a tubular mold the problem of the formation of fins usually does not occur and means reduced maintenance costs.
  • a small wall thickness of the mold tube has the disadvantage, however, that the high (coolant) pressures acting on the mold tube can lead to deformation of the mold tube and consequently to a shortened service life of the mold tube.
  • One object of the invention is to improve the disadvantages of the prior art in tubular molds.
  • Another object of the invention is to enable a mold unit which has a mold tube with a polygonal cross-sectional shape and a coolant conduction jacket surrounding the mold tube and forming a coolant gap with the mold tube, or a continuous caster equipped with such a mold unit to achieve a long service life .
  • the mold unit according to the invention for the continuous casting of metal products comprises a mold unit for the continuous casting of metal products, in particular for the continuous casting of blooms, comprising a mold tube with a polygonal cross-sectional shape and a coolant conduction jacket surrounding the mold tube and forming a coolant gap with the mold tube.
  • the multiple separate reinforcing plates are arranged outside the coolant conduction jacket and attached to one another on the mold tube without contact.
  • the individual, separate reinforcing plates (which are arranged outside the coolant conduction jacket and attached to the mold tube (- and thus “reinforce” or “keep in shape”) the mold tube) do not touch each other , ie they are not connected to one another - and so free from one another.
  • a "plate” can be seen as a flat, on two opposite sides, i.e. H. a plate top and a plate underside, each defined by a piece of, in particular hard, material bounded by an area that is extended in relation to a plate thickness.
  • contactless or “contactless” (of the separate reinforcing plates to one another) can be understood in particular to mean that the separate reinforcing plates are not directly connected to one another in a material, form-fitting or force-fitting manner.
  • polygonal is also not necessarily to be understood in a strictly mathematical or geometric sense.
  • a “polygonal” (cross-sectional) shape such as a rectangular (cross-sectional) shape, in particular a (cross-sectional) shape with rounded corners can be understood.
  • the mold tube of the mold unit is a casting mold which has several side walls, i. H. the tubular mold side walls, or tubular mold side faces for short, which are formed integrally with one another.
  • the invention is based on the knowledge that during operation of the mold unit there is a thermal expansion or thermal movement of the mold tube - as well as - connected to this - the reinforcement plates - fastened to it.
  • the reinforcement plates which are intended to reinforce the mold tube or to keep it in shape, are in contact with one another or touch one another, for example when they are screwed together, the reinforcement plates are prevented from thermal expansion. This can lead to mechanical stresses, particularly in corner areas of the mold tube, which can damage the reinforcement plates and / or on the mold tube and consequently can lead to a shortened service life of the mold unit.
  • the separate reinforcement plates are each "laid out” in a floating position, i.e. that is, outside the coolant duct, separated from the tubular mold / mold tube or its tubular mold wall / mold tube wall or walls and arranged below / to one another without contact or contact or on the tubular mold / mold tube or on a tubular mold wall / mold tube wall or on the tubular mold / mold pipe walls / side surfaces attached.
  • the respective tubular mold / mold tube wall / side surface thus has "its individual support wall” - with the separate reinforcement plate fastened to it in this way - and is held or supported by this in the form.
  • tubular molds in the tubular mold unit can also be built for formats of any size, especially large casting formats, without constantly increasing the tubular mold / mold tube wall thickness (which would worsen the cooling). Wall thicknesses can be kept constant - "thin-walled" - at approx. 20 to 25 mm.
  • the mold tube is preferably a copper tube. That is to say that the mold tube is preferably made of copper or a copper alloy. This ensures that the mold tube has a high thermal conductivity.
  • the reinforcement plates mentioned above can for example be made of stainless steel, for example of the steel grade WNr. 1.4301.
  • the mold tube has a mold cavity which, in cross section of the mold tube, has a rectangular shape, in particular a rectangular shape with rounded or pre-chamfered corners.
  • said rectangular shape of the mold cavity has a length of at least 280 mm, in particular at least 320 mm, and / or a width of at least 240 mm, in particular at least 280 mm. This means that large casting formats in particular are produced here.
  • the wall thickness of the mold tube can be constant over the entire mold tube.
  • the mold tube can have different wall thicknesses.
  • the formulation that the mold tube has a wall thickness of at most 35 mm or at most 30/25/20 mm can be understood as meaning that the wall thickness of the mold tube at its / its thickest point (s) is at most 35 mm or at most 30/25/20 mm.
  • a mold tube wall / side surface has its own “individual” separate reinforcement plate, which - fastened there - keeps it in shape. That is, it is provided here that the mold tube has a plurality of mold tube side surfaces and each separate reinforcement plate is attached to a different mold tube side surface. If necessary, a respective separate reinforcement plate can thus be adapted to "its" respective mold tube wall / side surface.
  • each mold tube wall / side surface of the tube mold has its own “individual” separate reinforcement plate.
  • the number of separate reinforcement plates corresponds to the number of mold tube walls / side surfaces, one of the separate reinforcement plates being fastened to each mold tube side surface / wall.
  • the fastening of one or the separate reinforcement plates to the mold tube can also take place selectively, for example by means of sleeves and / or retaining screws, which point fastenings then the coolant conduction jacket, for example for the coolant “water” also called “water conduction jacket” (and the coolant gap or Water gap) enforce stilt-like, the coolant / water gap is not restricted "over a large area”.
  • penetrations are sealed, for example by means of O-rings or the like.
  • the number of fastening systems can expediently be selected depending on the shape and / or dimensions and / or wall thickness of the mold tube, for example from 10 to 50 fastening systems, in particular 10 to 20 fastening systems for casting formats from 350 to 420 mm or 15 to 30 fastening systems for Casting formats from 420 mm to 500 mm or 25 to 40 fastening systems for casting formats from 500 to 530 mm.
  • the fastening systems can be arranged symmetrically and / or in columns or rows.
  • Such a fastening system can provide a connecting element (for example a “fixing / retaining screw”) which has a threaded section and a threaded insert which is inserted, in particular screwed, into a recess in the mold tube.
  • a connecting element for example a “fixing / retaining screw”
  • fixing / retaining screw which has a threaded section and a threaded insert which is inserted, in particular screwed, into a recess in the mold tube.
  • a threaded section of a connecting element is to be understood as a section of the connecting element provided with a thread.
  • the connecting element can then be screwed into the threaded insert by means of its threaded section.
  • the threaded inserts enable the reinforcement plates to be installed quickly and easily on the mold tube using connecting elements.
  • the connecting element is designed as a screw ("fixing / retaining screw”) with a threadless screw shaft section, in particular with the threaded section at one end of the screw and a screw head or a head nut that can be screwed onto the screw at another End of the screw.
  • Such a screw can, for example, be an M12 screw according to DIN.
  • Fastening systems designed "slim" in this way have the particular advantage that lateral thermal expansions / movements of individual tubular mold walls / side surfaces can be compensated for.
  • the fastening system has an adjusting screw sleeve which is screwed into a through hole in the separate reinforcing plate and which surrounds part of the connecting element, in particular the threadless screw shaft section.
  • the screw-on adjustment sleeve can lie on the outside of the mold tube (and / or on the threaded insert) on the front side - and the screw head or the head nut can - on the other end, on the screw-on sleeve on the front side - rest on the screw-on screw sleeve.
  • the screw-on sleeve can also be clamped between the reinforcement plate and the mold tube in this way.
  • the adjusting screw sleeve or the adjusting screw sleeve of such fastening systems can be used for the separate reinforcement plates with a fixed axial length or e.g. can be made axially adjustable through the screw connection.
  • tubular chill tubes can thus be manufactured using the drawing process without subsequent machining of the outer surface ("unmachined tubular chill tubes").
  • washers and the like can also be used in the fastening systems.
  • Spring elements such as one or more disc springs, can also be used.
  • the mold tube, the coolant conduction jacket and the separate reinforcement plates are arranged in a coolant, in particular water tank ("wet storage").

  • dry storage can be provided in which the separate reinforcement plates are not in contact with the coolant, ie are independent of the mold tube cooling.
  • the separate reinforcement plates since the separate reinforcement plates are independent of the mold tube cooling, vary in shape and thus be designed according to a given deformation profile of the tube mold or a tube mold / mold tube wall / side surface.
  • a full-surface design of a separate reinforcement plate is usually favorable.
  • the shape can, however, also have openings and / or be clasp-shaped or rib-shaped, optionally also made from a single element. If necessary, these openings can also be used for sensors.
  • the (plate) thickness or wall / plate thickness of a separate reinforcement plate can expediently be selected depending on the shape and / or dimensions and / or wall thickness of the mold tube, for example from 40 mm to 120 mm, in particular 50 mm for casting formats from 350 to 420 mm or 80 mm for casting formats from 420 mm to 500 mm or 100 mm for casting formats from 500 to 530 mm.
