Definitions

  • the present invention concerns an apparatus for continuous casting that allows to continuously cast metal products such as slabs with a rectangular section and bars with a double "T" section, also known as "beam blanks".
  • the apparatus for continuous casting allows to install both crystallizers of the tubular type and also crystallizers of the plate type.
  • An apparatus for continuous casting comprising a support structure or framework, defining a closed tubular support body, or body to support and contain the mold, hereinafter indicated as mold body.
  • the mold body can allow to install a mold of the tubular type or plate type.
  • Molds of the tubular type allow to obtain metal products with very simple and even cross section, for example blooms or billets with a round or square section, or with a more complex cross section but of limited size.
  • Known molds of a tubular type comprise a first tubular element, external during use, called conveyor, and a second tubular element, internal during use, called crystallizer.
  • the crystallizer usually made of copper or its alloys, has a through cavity with a shape and size substantially analogous to those of the metal product to be cast.
  • the external surfaces of the crystallizer because of the high working temperature, are constantly cooled by a cooling liquid, usually water.
  • a hollow space is provided or a plurality of cooling channels, for the passage and conveyance of the water.
  • the cooling water is made to circulate from a first end of the crystallizer, corresponding to the end from which the cast product exits, to a second end, corresponding to the end in which the molten metal is cast, in practice obtaining a counter-flow cooling with respect to the product.
  • the mold thus obtained is inserted in the mold body which, together with the mold, defines a containing compartment.
  • the containing compartment is divided into two halves by means of a separator element in order to define, together with the mold, two chambers containing cooling water, also called water boxes.
  • the fluidic connection between the first containing chamber and the second containing chamber is made by the hollow space, or by the cooling channels, comprised between the conveyor and the crystallizer.
  • the cooling water is introduced into the first water containing chamber, passes through the hollow space or the cooling channels and exits into the second containing chamber in order to be subsequently discharged.
  • Crystallizers of the plate type are also known, generally used for casting billets or blooms with a rectangular section, or Beam Blanks.
  • Said crystallizers of the plate type comprise four plates connected to each other to define, with their surface which during use faces toward the inside, a cavity for the passage of the liquid metal.
  • each crystallizer is reciprocally connected by means of a frame provided with four frame elements, each of which is associated to one of the plates.
  • the four frame elements are reciprocally connected in correspondence to their lateral edges in order to close the plates inside them.
  • the plates are coupled with each other in correspondence to respective connection edges.
  • connection means which can provide to make holes, threaded or not, into which screws or stud bolts are screwed, centering or clamping pins are inserted and/or elastic elements are associated.
  • the plates have lateral edges shaped to define together respective same-shape couplings.
  • Direct connection means are not provided between the plates, since they could require an increase in thickness of the plates or could stiffen the structure too much, causing the onset of internal tensions because of thermal stresses.
  • connection between the plates and the frame is particularly complex and uneconomic in terms of assembly time and the number of components used.
  • each plate of a plate crystallizer is provided with a plurality of cooling channels for the circulation of the cooling water.
  • the cooling channels can be made directly in the thickness of each plate. It is also known to make, on the surface of the plates which, during use, faces toward the outside, longitudinal grooves that are closed by a closing slab to define said cooling channels.
  • the position of the cooling channels in the plates is planned as a function of the differentiated cooling conditions of the internal surfaces of the crystallizer.
  • each plate the inlet and outlet ends of the cooling channels are referred to a single inlet collector and respectively a single outlet collector.
  • the inlet and outlet collectors are connected in their turn to a plant for feeding and treating the cooling water.
  • the differentiated cooling action prevents the onset of internal tensions or cracks that are damaging for the cast metal product.
  • the inlet and outlet collectors comprise ports to introduce and discharge the water, made in the frame elements and which connect to each other near access apertures to the cooling channels provided in the plates.
  • the introduction and discharge ports in their turn connect, with suitable pipes, to the plant that feeds and treats the water.
  • One purpose of the present invention is to make an apparatus for continuous casting that allows to selectively install in the same mold body crystallizers of the tubular type or crystallizers of the plate type.
  • Another purpose of the present invention is to make an apparatus for continuous casting that allows to renew already existing apparatuses, in a simple manner, provided for example for the installation of tubular crystallizers, making them suitable also for the installation of plate crystallizers.
  • Another purpose of the present invention is to make an apparatus for continuous casting that allows to assemble the crystallizers in the mold body in a simple and rapid way.
  • Another purpose of the present invention is to reduce the complexity of connection between the plates of a crystallizer of the plate type.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • an apparatus for continuous casting comprises a support structure provided with a containing casing configured to support inside it a mold equipped with a plurality of longitudinal passage channels for the passage of a cooling liquid.
  • the containing casing and the mold together define an introduction chamber and a discharge chamber for the cooling liquid.
  • Some forms of embodiment of the present invention may provide that the introduction chamber and the discharge chamber are separated by a separator element associated to the mold and to the containing casing.
  • the introduction chamber and the discharge chamber are fluidically connected by the passage channels, in which, during use, the cooling liquid is made to flow to constantly cool the mold and preserve its dimensional and mechanical characteristics.
  • the mold comprises a first tubular element and a second tubular element disposed inside said first tubular element so that only the first tubular element is located in direct contact with the cooling liquid contained in the introduction chamber and the discharge chamber.
  • the second tubular element comprises a plurality of plates each provided with said passage channels and connected to each other to define a through casting cavity.
  • the first tubular element is provided with connection members to connect said passage channels of the plates respectively with the introduction chamber and with the discharge chamber and thus achieve the cooling of the plates.
  • the configuration described above therefore allows to associate crystallizers of the plate type to a substantially known support structure normally configured for the installation of tubular crystallizers, thus increasing the versatility of said structure.
  • a hollow space is defined between the first tubular element and the second tubular element which drains possible infiltrations of cooling liquid between the first and the second tubular element.
  • possible infiltrations of cooling liquid in the casting cavity are avoided which, because of contact between the cooling liquid and the melted metal, could also cause explosions. This would compromise the functioning and the integrity of the apparatus and adjoining structures, also causing a serious risk for the safety of the operators.
  • each of the plates is served by its own connection members.
  • each of the connection members is connected to a plurality of said passage channels.
  • flow adjustment members provided to adjust the flow rate of cooling liquid in the passage channels, are associated to at least one of the connection members.

  • the second housing seatings 81 of the second positioning devices 72 are configured to constrain the position of the third 29a and the fourth 29b plate in a direction parallel to the longitudinal axis Z and to leave the movement free in a transverse direction, in this specific case, orthogonal, to the longitudinal axis Z, to allow any necessary adaption if the plates 28a, 28b, 29a, 29b are regenerated and if the thickness of the spacer 56 is modified.
  • the first plate 28a changes its total thickness and, in order to maintain the positioning of the internal profile unchanged with respect to the machine, a spacer 56 is inserted, with a calibrated thickness with respect to the support frame 26. These operations produce very slight movements of the theoretical center of the plates 28b, 29a, 29b.
  • the positioning of the crystallizer 27 in the support frame 26 is given by the abutment to which the first plate 28a is attached.
  • a rigid positioning constraint makes it impossible to assemble the crystallizer 27 in the support frame 26.

  • the freedom of movement of the plates 28a, 28b, 29a, 29b with respect to the pins 73 allows to take into account possible thermal dilations to which the latter are subjected during use, and thus prevent the onset of internal stresses that could deform the crystallizer 27, generating cast products with unwanted geometric and microstructural characteristics, as well as reducing the useful life of the 5 crystallizer 27 itself.
