摘要:
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.

A ladle swing tower for a continuous casting installation or plant equipped with pivotal carrier arms for the transport of casting or pouring vessels to and from a casting position. There is provided an inner rotatable structure of the ladle swing tower possessing at its lower end a bearing block located at the plane of the floor of the plant. There is also provided an outer stationary structure possessing a guide track at the level of the casting platform for rollers arranged at the inner rotatable structure.
摘要:
In continuous casting, the cast strand which emerges from the casting mold is conducted through a secondary cooling zone wherein it is guided and supported between latticed guide plates having guide faces which contact areas of the surface of the casting which are supported thereby, and having windows therethrough bounded by said guide faces. The unsupported areas of the surface of the casting which are exposed by said windows are cooled by sprays of cooling water from spray nozzles located in the windows.

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.
