Problems solved by technology
[0008] The nozzle adjustment works within the slab guide at a short distance from the hot metal slab in areas of high thermal load and is also subject to high contamination loads, so that the articulation of this complex kinematic chain is functionally easy malfunction
In addition, the moving components in the strand guide element or the strand guide section are located in areas that are difficult to access and therefore difficult to carry out repair work

The subject matter of the invention is a spray-nozzle adjusting device in a strand guide (2) of a continuous casting plant for producing metal strands of different strand width, wherein the strand guide comprises strand guide rollers (3, 3a, 3b, 3c, ...) which are supported in a support frame (2a) and form a transport path (1c) for the metal strand, and at least two spray nozzles (5a, 5b) are assigned to this transport path in a plane lying normal to the strand delivery direction (R) between adjacent strand guide rollers, said spray nozzles (5a, 5b) each being connected to an adjusting device(12) for changing the distance between the spray nozzles and for changing the normal distance of the spray nozzles from the transport path. To ensure ease of maintenance and good accessibility of theadjusting device, it is proposed that a spray nozzle holder (10) be assigned to each spray nozzle (5a, 5b) arranged in a plane lying normal to the strand delivery direction and that the spray nozzle holder be fastened to an actuating piston (11) of at least one adjusting device (12), wherein, during an axial adjusting movement of the actuating piston, an adjusting movement of the spray nozzles which is parallel to this axial adjusting movement is effected, and the adjusting device (12) is fastened to the support frame (2a) of the strand guide (2) in a region lying at a distance from the transport path (1c).
Description
technical field [0001] The invention relates to a nozzle adjusting device in a slab guiding device of a continuous casting plant for producing metal slabs of different slab widths, wherein the slab guiding device comprises a support on Slab guide rollers in the frame frame, the slab guide rollers constitute the conveying rails for the metal slabs and the conveying rails are arranged between adjacent slab guide rollers in a plane normal to the conveying direction of the slabs There are at least two nozzles, the nozzles are respectively connected with the adjustment device to change the distance between the nozzles and the normal distance between the nozzles and the surface of the conveying guide rail. Background technique [0002] In the continuous casting plant, the at least partially hardened slab leaving the continuous casting mold will be subjected to High-intensity jet cooling. The cooling medium (mostly spray water or water-air mixture) will be sprayed in a fan-shaped...
