Definitions

  • the invention relates to an inspection system for simultaneously checking the functionality of several spray nozzles in a continuous casting system, in particular the spray nozzles arranged between two strand guide rollers.
  • the invention further relates to a method for simultaneously checking the functionality of several spray nozzles in a continuous casting system, in particular of the spray nozzles arranged between two strand guide rollers.
  • a device and a method for optically inspecting a spray nozzle in a continuous casting plant is in the prior art, for example from the German published patent application DE 10 2011 005 860 A1 known.
  • this publication discloses a device for testing a spray nozzle in a continuous casting plant, the device having a running member, e.g. B. has a roller checker or a cold strand chain for passing through the continuous casting system.
  • An optoelectronic sensor in particular a video camera, is attached to the running member, with the help 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 using a preferably automatic image evaluation method.
  • 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 of the nozzle parameters.
  • the published patent application discloses that the device includes a light source in order to appropriately illuminate the cooling nozzles to be photographed.
  • a comparable device is from the CN 108907126 A known.

  • a corresponding known inspection system has, in addition to the spray nozzle, at least one camera for recording an image and a light source.
  • the EP 3 456 436 A1 proposed to design 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 to produce 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.
  • spray nozzles are arranged in the upper and lower areas between adjacent guide rollers of the continuous casting system, which 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 system between adjacent strand guide rollers. So that the entire upper or lower surface of the strand produced is cooled evenly by the spray nozzles, the spray patterns generated by the spray nozzles overlap in the lower region, in the immediate vicinity of the upper or lower surface of the strand produced.
  • the aforementioned devices and methods for checking the spray nozzles provide the Continuous casting plant does not provide detailed results about 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 casting system in order to be able to better assess the cooling performance of the secondary cooling of the continuous casting system and to avoid surface defects on the strand produced caused by 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 system according to claim 1.
  • the inspection system comprises a separate optoelectronic sensor for each spray nozzle to be checked at the same time, i.e. usually between 6 and 14 optoelectronic sensors.
  • the separate optoelectronic sensors are expediently aligned with a spray nozzle, more precisely with the spray pattern generated by the spray nozzle.
  • the inspection system further comprises means for assigning the spray patterns generated by the spray nozzles to be checked to at least one optoelectronic sensor. This allows the of the Check the spray patterns generated by individual spray nozzles separately. By checking the spray pattern generated by a spray nozzle, a statement can be made about the functionality of the spray nozzle and thus about the secondary cooling of the continuous casting system as a whole.
  • the inspection system further comprises at least one lamp for illuminating the spray patterns generated by the spray nozzles to be checked, in particular in the visible and/or invisible light spectrum.
  • the detection of the spray patterns by the corresponding optoelectronic sensors is improved.
  • the optoelectronic ones are expediently tuned to the light spectrum emitted by the at least one lamp.
  • the at least one light source 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 lamp from the side facing away from the optoelectronic sensors.
  • the inspection system is part of a cold strand chain or is designed to be connectable to a cold strand chain.
  • the inspection system is therefore either an integral part of the cold strand chain or can be connected to it as required.
  • the inspection system is arranged at the front end of the cold strand chain in the direction of travel.
  • the optoelectronic sensors are aligned forward in the running direction of the continuous casting system. This has the advantage that the optoelectronic sensors record the spray patterns beforehand they move through the spray patterns. Subsequently, the water from the spray patterns that has hit the optoelectronic sensors can at least partially run off to the next spray nozzles to be checked in the next gap between adjacent strand guide rollers, which is advantageous for detecting the spray patterns.
  • the inspection system further comprises an impact element on which the spray patterns generated by the spray nozzles to be checked impinge, in particular for separating the spray nozzles arranged in the upper region of the continuous casting system from the spray nozzles arranged in the lower region of the continuous casting system.

  • the spray patterns generated by the spray nozzles to be checked at the same time are physically separated from each other by the mechanical deflectors.

For example, if the continuous casting plant extends horizontally, the deflectors are arranged vertically and along the direction of travel of the continuous casting plant.
  • the mechanical deflectors physically separate the spray patterns produced by the spray nozzles being inspected, making it easier to capture and verify the spray patterns.
  • At least the middle ones of the spray patterns generated by the plurality of spray nozzles are each separated from the neighboring pointed pattern by a deflector.
  • mechanical deflectors can also be arranged on the outer edges in order to protect the spray patterns arranged on the outer edge from external influences.
  • the deflectors are designed to be changeable, in particular with regard to the number and/or position, in order to adapt the inspection system to a variable number of spray nozzles to be checked or their positioning in the continuous casting system.
  • This can be achieved, for example, by making individual deflectors between different optoelectronic sensors extendable, foldable or are the like.
  • individual deflectors it is possible for individual deflectors to be foldable in such a way that they cover an optoelectronic sensor in a first position, i.e. make it inactive, or provide separation from an adjacent optoelectronic sensor in a second position and thus activate the optoelectronic sensor.
  • the means for assigning the spray patterns generated by the spray nozzles to be checked to an optoelectronic sensor are designed as an optical separator.
  • the spray patterns generated by the spray nozzles to be checked are therefore optically separated from one another.

  • the inspection system further comprises a storage device for storing the recorded spray patterns of the spray nozzles to be checked, a computing device for comparing the recorded 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 casting plant can first be saved and subsequently evaluated.
  • the evaluation can be carried out by a computing device in the inspection system or by an external computing device.
  • the data collected by the inspection system and/or results of the evaluation can, for example, be transmitted to an external device via a communication interface. Known transmission methods such as Bluetooth, WiFi, NFC or the like can also be used.
  • the inspection system comprises a position sensor for detecting the position of the inspection system in the continuous casting plant. This makes it easier and more precise to assign the measurement results of the inspection system to the spray nozzles of the continuous casting system.
