Definitions

  • the invention relates to a device for the continuous casting of molten metal, preferably molten steel to cast strip according to the features of the preamble of claim 1.
  • the cast strip Since the cast strip has high temperatures when leaving the casting gap, it forms on its surface on contact with oxygen to scale formation, which hinders the continuous processing of the strip. In particular, the scale negatively affects the work result of the inline hot rolling subsequently performed on the casting of the strip.
  • the direct heat radiation of the very hot strip emerging from the casting gap reduces the rapid cooling of the casting roll surface and also causes contamination of the casting roll surface by dirt particles which may be contained in the upwardly flowing hot gas masses under the two casting rolls.
  • a two-roll caster is known in which at a greater distance from the casting rolls, a refractory shield is attached to the support frame of the casting rolls.
  • This shield forms for the cast metal strip an inlet funnel in a downstream transport chamber, but without effectively shielding the radiating over a longer distance from the metal strip heat from the casting rolls- Also in the passage area of the shield due to operating swung in varying degrees metal strip prevents sufficient shielding of the transport chamber the casting rolls.
  • the invention has for its object to avoid these disadvantages described and to provide a device of the type described above, in which a Gellowalzen LCD with minimal installation costs during the change process is feasible and at the same time the burden of the casting rolls and the surrounding structure supporting them by the cast strip emitted heat is reduced.
  • the casting roll shield provided in the device according to the invention thus makes possible a particularly effective protection of the casting rolls, the components required for their storage and their operation and all other aggregates arranged in the vicinity of the casting rolls against rising gases heated by the cast strip.
  • the casting roll shield can in this case be connected directly or indirectly with the frame receiving the casting roll bearings.
  • the casting roll bearings (2a, 3a) receiving the casting rolls (2, 3) rest on a frame (25) and the casting roll shield (10) adjoins the supporting frame (25).
  • Such a compact assembly is formed, which is easily manipulated as such between a working position and a waiting position.
  • the casting roll bearings (2a, 3a) receiving the casting rolls (2, 3) are suspended from the frame (25) and the casting roll shield (10) is attached to the casting roll layers (2a, 3a).
  • This training variant also offers the advantages of a compact module.
  • the frame with the casting rolls and the casting roll shield can be replaced with a roll change as a complete unit.
  • the frame with the casting rolls and the casting roll shield can be replaced with a roll change as a complete unit.
  • the casting roll shielding can be matched to the dimensions of the casting rolls at the same time in a simple manner.
  • An embodiment of the invention that is favorable with regard to the protective effect of the thermal shield as well as with regard to reduced casting roll contamination is characterized in that the casting roll shield extends in a pointed roof shape into the space delimited by the casting rolls and located below the casting gap.
  • the inlet opening for passing the casting strip emerging from the cast strip is preferably formed in the ridge region of the shield.
  • the edges of the inlet opening of the casting roll shield axially parallel to the casting rolls with a gap to the casting rolls.
  • the Gellowalzen shield in the casting rolls forms only a lateral boundary of the cooling zone, while the upper limit is formed by the casting rolls themselves.
  • the casting roll shield additionally has walls which extend in the region of the casting roll end faces parallel to these, so that at least the edges of these walls are arranged with a gap to the end faces of the casting rolls.
  • an enclosure which at least partially surrounds the conveying path of the cast strip, then it is favorable if the cast-roll shield is placed on such a housing or is part of such an enclosure.
  • the housing together with the casting roller shield preferably encloses the conveying path of the cast strip at least up to a first pair of rollers arranged in the conveying path for conveying or hot rolling the strip. This embodiment proves to be particularly useful if an inert atmosphere is maintained in the enclosure to suppress the formation of scale.
  • an enclosure is associated with the casting-roll shield, it is advantageous in view of the possibility of simple, regular maintenance if this casting-roll shield is detachably connected to the housing. This is especially true when the casting roll shield is connected to a transportable frame. In this case, there should be a seal between the casting roll shield and the enclosure to withstand the thermal stresses in the area of the two-roll casting machine. This can be accomplished in that it is in the form of a sand-filled channel, in which the casting roller shield dips with its lower edge after lowering the casting roller shield on housing.
  • the G manwalzenlager supporting frame is supported on a roadway transporting device, preferably a chassis, for its movement between a working position or operating position and a waiting position and vice versa.
  • the casting roll shield is separated from the arranged on the housing seal in that the Gellowalzenlager supporting frame relative to the roadway or the chassis, preferably by a lifting or swinging, height adjustable.
  • a quickly feasible and a high setting accuracy having arrangement of the change device is when the raised or lowered with a lifting or swinging frame formed in the working position rests centered on an intermediate plate and spent for displacement in a waiting position in a relation to the intermediate plate raised position ,
  • centering devices are used to lower the frame on the intermediate plate for positionally accurate adjustment of the two components to each other, which ensure a centering both in the lateral and in the transverse direction sure.
  • independently acting centering devices are provided for centering in each of the two directions.
  • the shielding against rising hot gases is particularly efficient when this casting roll shield defines a cooling zone in which during the casting operation a temperature lower than the temperature of the gases heated by the cast strip prevails. As a result, a zone is formed close to the outlet region of the casting gap, in which a targeted lowering of the temperature is brought about.
  • This cooling causes the natural, thermally induced flow (Chimney effect) interrupted, in which the heated by the cast strip during its transport over the conveying path gases against the conveying direction of the belt ascend.
  • the cooling zone thus forms a barrier which prevents the hot gases heated by the strip from reaching the components required for supporting the casting rolls.
  • the G confusewalzen-shielding is such a physical obstacle by which the flow of hot gases to the casting rolls or in the casting rolls, for example, existing work platform is interrupted. At the same time, the shielding is available for targeted cooling of the gases in the space defined by it. In the same way, the casting roller shielding in combination with a cooling of the gases in the cooling zone leads to a significant reduction in the risk of personnel employed in the casting rolls.
  • the formation of a cooling zone in the area bounded by the casting roll shield can be produced, for example, by connecting at least one of the walls of the casting roll shield to a coolant supply device.
  • the formation of a cooling zone is further realized in that at least one of the walls of the casting roll shield is fluid cooled.
  • the cooled wall has at least one cooling channel through which the cooling fluid flows during the casting operation.
  • Such liquid cooling ensures that the heat applied to the casting roll shield is dissipated quickly and efficiently.
  • the cooling of the casting roll shield results in intensive cooling of the gases impinging on the casting roll shield, which mix with the hot gases flowing in the area bounded by the shield so that they too are cooled and a lower temperature zone is established.
  • the formation of the cooling zone can also be supported particularly effectively by providing at least one device for blowing cooling gas into the cooling zone.
  • the effect of the cooling gas can be additionally improved if the flow of the cooling gas blown into the cooling zone is directed substantially counter to the flow direction of the heated from the cast strip gases.
  • This orientation of the cooling gas flow leads to an intensive mixing of the hot gases with the cooling gas, so that within a short time a particularly effective cooling zone is established and the rise of hot gases on the Gellowalzen-shielding is particularly sure prevented. Further, the effectiveness of the cooling gas flow can be increased by sweeping the surface of the cast strip.
  • the tape itself are cooled and reduces the heat radiation emitted by it, so that the coming into contact with the band in the course of further conveying gas less heated.
  • the gas flow directed against the surface of the belt forms, in addition to the thermal barrier, a fluidic barrier by which the rise of hot gases directly at the surface of the belt is also suppressed.
  • the cooling of the strip achieved in the region of the cooling zone reduces the amount of scale formed on the strip surface during the transport of the strip.
  • the formation of scale can be further suppressed in cases in which an inert cooling gas is blown into the cooling area.
  • Oxidation of the strip which is undesirable for many applications, can be counteracted by blowing in a reducing cooling gas into the cooling zone as an alternative or in addition to the injection of inert gas.
  • nozzles are present in the region of the inlet opening, from which a gas stream emerges during the casting operation, which counteracts the escape of gas from the inlet opening.
  • this can be achieved, for example, by directing a gas flow in the manner of a gas jet knife against the strip.
  • a gas jet can be directed in a corresponding manner against the casting rolls.
  • cast roll shield is coated with refractory material on its surfaces associated with the cast strip to aid its heat-insulating action.
  • the load on the units and components of the two-roll casting apparatus can be further reduced by providing a suction device for extracting the gases heated by the cast strip.
  • the housing may have a suction opening to which the suction device is connected.
  • FIGS. 1 and 2 Designed as a two-roll casting apparatus 1 for casting a molten steel to a cast steel strip B, as shown in the FIGS. 1 and 2 is schematically shown, has two axially parallel to each other and arranged opposite to each other rotating casting rolls 2, 3, which define the longitudinal sides of a casting gap formed between them 4 and arranged above the melt sump 5, in which the molten steel is fed from an intermediate vessel or a ladle, not shown ,
