Definitions

  • the invention relates to a method for cooling continuously conveyed casting strands in a continuous casting installation, wherein coolant jets emerging from a nozzle slot strike the strand surface at different angles across the width of the casting strand.
  • the invention also relates to a flat jet nozzle for performing the method.
  • the object of the invention is to provide a simple method for cooling casting strands with a coolant quantity distribution over the strand width which effects a uniform, gentle and rapid cooling of the strand surface.
  • This object is achieved according to the invention in that cooling directed at width regions of the strand surface average quantities Q are measured taking into account their impact angle ⁇ in the sense of uniform heat dissipation.
  • the amounts of coolant directed towards the width regions of the strand surface are dimensioned according to the angle of impact and the mixed state in the respective region of impact.
  • the mixed state is to be understood as the mixing ratio and the water droplet size upon impact.
  • the width of an outlet slot is determined at every point according to the angle of incidence of the emerging coolant jet.
  • the outlet slot can extend in front of an impact surface in the circumferential direction of the flat jet nozzle.
  • the outlet slot can be arranged parallel to the inflow opening on the side of the flat jet nozzle.
  • a particularly cost-effective design of the flat jet nozzle is seen in the fact that the outlet slot is partially placed on a side bore of the flat jet nozzle Cover is formed, which is fastened by a bolt penetrating the side bore.
  • the flat jet nozzle can advantageously be arranged on a mixing valve provided with cooling water connection and air connection for two-substance cooling.
  • a T-shaped mixing valve 1 is provided with a connecting nipple 2, 3 each for an air supply line and a water supply line.
  • a nozzle tube 4, to which a flat jet nozzle 5 is connected, is screwed in on an outlet side of the mixer fitting 1.
  • the flat jet nozzle 5 is provided with an inlet opening 6 and a side bore 7 at right angles thereto, the lower wall 8 of which acts as an impact surface.
  • the side bore 7 is provided with a cover 9, which is fastened to the opposite wall of the flat jet nozzle 5 by a bolt 10 penetrating the side bore 7.
  • the lower wall 8 of the flat jet nozzle 5 is angularly excluded to form an outlet slot 11 on the side of the cover 9.
  • a flat jet nozzle 13 screwed to a nozzle tube 12 is provided with an outlet slot 15 in its wall immediately in front of an impact surface 14 on the end face.
  • the coolant is sprayed through the outlet slots 11, 15 of the flat jet nozzle 5 or 13 in a fan 16 onto a casting strand surface 17, with individual coolant jets of the spray fan 16 having different angles of incidence, ⁇ 2 .
  • different amounts of coolant Q are defined for the width regions depending on the angle of incidence d.
  • the associated area of the outlet slot 11, 15 is defined in terms of its width according to the required coolant quantities Q. It can be seen from FIGS. 1 to 4 that the width of the outlet slots 11, 15 increases from the center to the sides. In this way, the outer regions of a cast strand surface 17 are subjected to a larger quantity of coolant Q in an increasingly defined manner to the outside (FIG. 5).
