Abstract: The invention relates to a method for producing foundry ingots (1) from metal, in particular from steel, having a cross-sectional area of more than 0.1 m2, wherein liquid metal (2) is discharged into an ingot mold (15) open at the bottom either directly form a casting ladle (11) or via a tundish (12), and wherein, by a drawing piston (28), which is vertically movable in the direction of a longitudinal axis (5) of the foundry ingot (1) and on which the foundry ingot (1) is at least indirectly arranged, the at least partially solidified foundry ingot (1) is drawn from the ingot mold (15) in the direction of the longitudinal axis (5).

Abstract: Spray nozzle device for spraying a cast strand or similar metallurgical products with a misty air/water mixture for uniformly cooling the cast strand. The air/water mixture is produced in a mixing chamber which acts as a diffusor and includes an air inlet, a water inlet, and a nozzle outlet approximately in alignment with the air inlet. The air inlet is arranged in an air inlet nozzle, the tip of which protrudes into an upper region of the mixing chamber and preferably has air outlet holes oriented perpendicular to a longitudinal axis of the mixing chamber. Water enters near the tip through at least one water outlet hole oriented perpendicular to the longitudinal axis and placed such that the water jet exiting the water outlet hole flows past the air outlet holes. The air flow or air pressure and the water flow or water pressure do not influence each other.

Abstract: The invention relates to a spray nozzle device for spraying a cast strand or similar metallurgical products with a misty air/water mixture in the form of a mist for uniformly cooling the cast strand. The air/water mixture is produced in a mixing chamber (2) of the spraying device. Said mixing chamber acts as a diffusor and is provided with an air inlet (3), a water inlet (4), and a nozzle outlet (5) oriented approximately in alignment with the air inlet. The air inlet (3) is arranged in an air inlet nozzle (6), the tip (7) of which protrudes into the upper region of the mixing chamber and preferably has a plurality of air outlet holes (9) there, which air outlet holes are oriented perpendicular to the longitudinal axis of the mixing chamber; Water enters near the tip (7) through at least one water outlet hole (11), which is oriented perpendicular to the longitudinal axis and which is placed in such a way that the water jet exiting the water outlet hole flows past the air outlet holes (9).

Abstract: With a continuous casting method for producing preliminary profiles, in particular double T preliminary profiles, the downwardly flowing cooling water is pushed out of the internal curve of the preliminary profile strand (3) via the profile flanges and discharged using water nozzles (21, 22) aligned substantially to the crossover from the bar (4) to the respective flange (5, 6) by means of the diverting water delivered via the water nozzles (21, 22). In this way the excessive cooling caused by downwardly running cooling water is largely avoided in the internal curve of the preliminary profile strand.

Abstract: The invention relates to a method and a device for guiding and orienting a strand (5) in a continuous casting facility for large-sized round sections made of steel or a similar material. In order to prevent the formation of cracks while the strand is oriented, the outer surface (15) of the strand is heated from above and from below inside the orienting track. For this purpose, porous burners (10, 17) are arranged in the discharge section of the directing track, the hot gas emitted from said burners flowing entirely around the outer surface (15) of the strand.
