Definitions
- the invention relates to an inspection system for simultaneously checking the functionality of several spray nozzles in a continuous caster, in particular of the spray nozzles arranged between two strand guide rollers.
- the invention also relates to a method for simultaneously checking the functionality of a plurality of spray nozzles in a continuous caster, in particular of the spray nozzles arranged between two strand guide rollers.
- a device and a method for the optical inspection of a spray nozzle in a continuous casting plant is known in the prior art, for example from the German patent application DE 102011 005860 A1. Specifically, this laid-open specification discloses a device for testing a spray nozzle in a continuous casting plant, the device being a barrel member, e.g. B.
- the device has a roller checker or a cold strand chain to pass through the continuous caster.
- An optoelectronic sensor in particular a video camera, is attached to the barrel member, with the aid of which the properties of the spray nozzle can be measured. With the help of the optical sensor, the spray pattern of the spray nozzle is recorded and then evaluated with the help of a preferably automatic image evaluation method. It is also provided that various nozzle parameters, in particular the coolant pressure of the nozzle, are varied and then a recording of the spray pattern is also made in response to this variation in the nozzle parameters. Furthermore, the laid-open specification discloses that the device comprises a lighting means in order to illuminate the cooling nozzles to be photographed accordingly.
- EP 3 456 436 A1 discloses an inspection system and a method for monitoring the functionality of at least one spray nozzle, in particular in a continuous casting plant.
- a corresponding known inspection system has at least one camera for recording an image and a light source.
- EP 3 456 436 A1 proposes designing the light source as a laser light source for emitting a plurality of preferably parallel light beams which span a projection surface for an image to be recorded.
- the spray nozzle is aligned with its outlet opening on one side of the projection surface in order to generate the image in the projection surface as spray spots of the sprayed liquid.
- the digital camera is used to record the image in the projection surface.
- a plurality of spray nozzles are arranged between adjacent guide rollers of the continuous caster in the upper and lower areas, which spray nozzles spray the entire upper and lower surface of the strand produced with water.
- spray nozzles are arranged on the top and bottom of the continuous casting plant between adjacent strand guide rollers. So that the entire upper or lower surface of the strand produced is evenly cooled by the spray nozzles, the spray patterns produced by the spray nozzles overlap in the lower area, in close proximity to the upper or lower surface of the strand produced. Due to this overlap, however, the aforementioned devices and methods for checking the spray nozzles provide the Continuous caster no detailed results on the functionality of individual spray nozzles.
- the present invention is therefore based on the object of checking the functionality of individual spray nozzles of a continuous caster in order to be able to better assess the cooling performance of the secondary cooling of the continuous caster and to avoid surface defects on the strand produced due to uneven or limited cooling.
- the object is achieved according to the invention by an inspection system for simultaneously checking the functionality of several spray nozzles in a continuous casting plant, in particular of the spray nozzles arranged between two strand guide rollers, comprising: at least one optoelectronic sensor for each spray nozzle to be checked simultaneously, and

- the optoelectronic ones are expediently matched to the light spectrum emitted by the at least one illuminant.
- the at least one illuminant is arranged on the opposite side of the spray patterns generated by the spray nozzles to be checked, like the optoelectronic sensors. The spray patterns generated are therefore irradiated by the at least one illuminant from the side facing away from the optoelectronic sensors.

- the optoelectronic sensors are oriented towards the front in the running direction of the continuous caster. This has the advantage that the optoelectronic sensors record the spray patterns before they move through the spray patterns. Subsequently, the water of the spray patterns that has hit the optoelectronic sensors can at least partially run off up to the next spray nozzles to be checked in the next gap between adjacent strand guide rollers, which is advantageous for the detection of the spray patterns.

- the inspection system further comprises a memory device for storing the captured spray patterns of the spray nozzles to be checked, a computing device for comparing the captured spray patterns of the spray nozzles to be checked with expected spray patterns and / or a communication interface for exchanging data with an external device.
- the storage device has the advantage that the data collected during the passage of the cold strand chain through the continuous caster can initially be stored and subsequently evaluated. The evaluation can be carried out by a computing device of the inspection system or by an external computing device.
