Abstract: In a method for producing a spray nozzle device, in particular for spraying a casting strand during casting of metallic products, the spray nozzle device includes a basic body with an air inlet, a water inlet and a nozzle body with a mixing chamber for producing an air/water mixture which emerges through at least one nozzle outlet. The air inlet is formed by at least one air inlet nozzle, with a nozzle tip projecting into the mixing chamber, and has at least one air outlet hole. The water inlet opens into the mixing chamber close to the nozzle tip of the air inlet through at least one water outlet hole oriented transversely to a longitudinal axis of the mixing chamber. At least one part region of the spray nozzle device is produced by a generative production process, preferably operating as a 3D printing process.

Abstract: The invention relates to a guide roller comprising a bearing journal (13) at each of two ends. Each bearing journal is provided with a plain bearing (14), which is designed as a hollow journal, and can be connected to the coolant supply line in order to conduct a coolant through the hollow journal into the coolant channel (12) or to conduct the coolant out of the coolant channel. The plain bearing (14) is lubricated by the coolant that is conducted through the bearing journal (13) designed as a hollow journal. A roller assembly for a strand casting system is provided with a plurality of said guide rollers (1). The guide rollers are arranged at an axial distance from each other along a strand (2) produced by the strand casting system and are each rotatably supported in a respective bearing mount (3). Each bearing mount is arranged on at least one frame part (4, 5) in a preloaded manner. The bearing mounts (3) are supported on the frame parts (4, 5) so as to be self-setting by means of elastically pliable connecting means (6). Even if the strand cross-section of the produced strand changes during the operating duration or due to changed process parameters, the originally set pressing force of the guide rollers remains substantially unchanged.

Abstract: A refractory casting tube for a mould for continuously casting molten metal is provided with a top part (33) and a bottom part (35) which dips into the molten metal in the inner mould space (6) during the casting. A refractory deflection element (35) is integrated in the funnel-shaped or similarly shaped inlet (34) of the top part (33) and is shaped in such a manner that a fluid-dynamic dissipation is generated on the molten metal (21) during casting in said inlet (4, 34). The molten steel therefore flows into the mould roughly as a uniform flow with a homogeneous and stable distribution.

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.
