Definitions
- the invention relates to a flat jet nozzle in a continuous casting installation for spraying a coolant onto a casting strand surface, the outlet slot of which forms a spray fan formed from a multiplicity of coolant jets, the angles of incidence associated with each coolant jet becoming smaller with respect to the side regions of the casting strand surface.
- a coolant jet striking the side surfaces of the casting strand strikes the strand surface with less kinetic energy due to its twice as large path than a water jet striking the middle of the strand perpendicularly.
- Both the smaller angle of incidence and the loss of energy additionally reduce the cooling effect of a certain amount of coolant, since they reduce the depth of penetration of the water drops into the vapor layer formed on the strand surface.
- a nozzle which has a plurality of parallel nozzle channels arranged next to one another in one plane and having the same or different diameters. All nozzle channels are connected in the mouth area by a transverse channel with parallel boundary surfaces.
- the object of the invention is to provide a simple spray nozzle for cooling casting strands in a wide spray fan formed from a plurality of coolant jets, the different heat dissipation resulting from different angles of incidence and throw lengths of the coolant jets being compensated for.
- 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 inexpensive embodiment of the flat jet nozzle is seen in the fact that the outlet slot is partially formed by a cover placed on a side bore of the flat jet nozzle, which is fastened by a bolt penetrating the side bore.
- a T-shaped mixing fitting 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 to form an outlet slot 11 on the side of the Cover 9 angularly excluded.
- 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 a, a 2 .
- different amounts of coolant 0 are defined for the width regions depending on the angle of incidence a.
- 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).
