Definitions

  • the invention relates to a spray nozzle adjustment device in a strand guide of a slab continuous casting plant for the production of metal strands of different strand width
  • the strand guide comprises supported in a scaffolding frame strand guide rollers, which form a transport path for the metal strand and this transport path in a normal to the strand conveying direction plane between adjacent , in strand conveying direction successive, strand guide rollers are associated with at least two spray nozzles with which fan-shaped coolant jets are applied to a broad side surface (1 a, 1 b) of the metal strand and each with an adjusting device for changing the distance of the spray nozzles to each other and to change the normal distance of Spray nozzles are connected by the transport path and each arranged in a plane perpendicular to the strand conveying direction plane spray nozzle is associated with a spray nozzle holder.
  • the coolant usually atomized water or a water-air mixture, is spray-shaped by means of spray nozzles into a free space between successive in the strand conveying direction strand guide rollers. Since in a continuous casting usually metal strands are cast with different strand width, it is necessary to position the spray nozzles so that a uniform coolant loading of the strand surface is achieved in a direction normal to the strand transport direction plane. In strands with slab cross-sections, this cooling is limited here mainly to the broad side surfaces of the cast strand.
  • a nozzle adjustment is known in which a plurality of spray nozzles are hinged to a lever system, for example in the manner of a parallel link system.
  • An adjustment of this lever system causes in the described embodiment with three arranged in a plane spray nozzles the formation of three Sprühf kauern that are adjustable at each selected slab width with constant overlap area and without overmolding the slab edges from an operating position to another operating position.
  • an element of the lever mechanism is moved with an adjusting spindle in the desired direction.

  • these movable internals are in the strand guide elements or segments in hard to reach areas, making repair work are difficult to perform.
  • Object of the present invention is therefore to avoid the disadvantages described above and to propose a Spritzdüsenverstell Surprise, which is characterized by particular ease of maintenance and good accessibility.
  • the angle of inclination of the adjusting piston of the adjustment to the imaginary surface of the transport path in a plane normal to the strand conveying direction corresponds to the opening angle of the emerging from the spray nozzle coolant jet.
  • the opening angle of the coolant jet is also in this plane.
  • the opening angle of the coolant jet issuing from the spray nozzle and thus the design of the spray nozzle must be determined so that the spray pressure of the coolant jet impinging on the strand surface does not vary too much depending on the distance of the spray nozzle from the metal strand surface.

  • treated cooling water water cooling
  • a nebulizer preferably air
  • atomized cooling water air-mist cooling
  • the number of necessary adjustment along the strand guide should be minimized. This can be achieved by assigning spray nozzles arranged one behind the other along the transport path in a plurality of successive planes in the strand conveying direction to a spray nozzle holder extending in the strand conveying direction and being synchronously adjustable with the latter.
