Definitions

  • the invention relates to an apparatus and a method for closing a drain opening in a metallurgical vessel.
  • the casting process takes place from liquid steel via pouring pans, intermediate containers (distribution channels) into oscillating molds with a downstream strand guiding system.
  • the targeted maximum emptying of the intermediate container / distributor channels takes place taking into account the actual casting speed, the current distributor weight and the experience of the casting master in manual or automatically controlled processes.
  • slag which floats on the melt
  • slag entering the continuous casting mold forces the casting process to cease because slag inclusions make the casting material unusable. Determining whether flaws exist in a processed cast material due to slag inclusions also increases the cost of the product.
  • This object is achieved with the subject matter of claim 1.
  • This article is characterized by a stopper rod disposed in the vessel above the drainage port for closing the drainage port; a stopper rod mechanism for raising and lowering the stopper rod; a sensor for detecting vibrations of the stopper rod or the stopper rod mechanism caused by the outflow of melt from the vessel through the discharge port; and a control device for controlling a closure means for the discharge opening of the vessel in accordance with the vibrations detected by the sensor on the stopper rod or on the stopper rod mechanism.
  • Vortex is synonymous with vertebrae.
  • eddies are called circular flows of a fluid.
  • a vortex forms because a sufficiently large velocity gradient occurs within the fluid. This means that a part of the liquid flows much faster than the rest.
  • the sensor which is located either on the stopper rod or on the stopper rod mechanism, detects the vibrations as a primary signal and passes it on to a control device.
  • the sensor forwards the oscillation of the stopper rod or the stopper rod mechanism directly and in the form of an electrical signal to the control device, and the closure of the discharge opening of the metallurgical vessel is effected immediately.
  • the vortex effect is detected earlier and the consequent closure of the drain opening occurs earlier than in the prior art, an optimal steel application with low losses is ensured in the present invention.
  • Optimal steel application is ensured when a maximum proportion of molten metal flows into the continuous casting mold and the proportion of slag is equal to zero. A safe, reproducible and targeted timely closing of the intermediate container / the distribution channel is given by this arrangement.
  • the closure device for the drainage opening is designed as a slide, which is arranged below the drainage opening, or as the stopper rod. Both closing operations of the drainage opening, either with the stopper rod or with the slide below the discharge opening, prevent the outflow of slag now contained in the melt from being prevented.
  • the slide can also be designed as emergency slide, ie that the drain opening can also be closed when the stopper rod does not close the drain opening sufficiently. This can occur, for example, due to technical defects.
  • the sensor which may be designed as an electrical vibration sensor, acceleration sensor, sound sensor, strain gauge, force sensor, pressure sensor or position sensor, detects the oscillation frequency at the plug or the stopper rod mechanism sufficiently and promptly and passes this detected vibration as an electrical signal to the control device.
  • Figure 1 shows the arrangement sketch of the device.
  • the device according to the invention and the method according to the invention are described in detail below with reference to FIG.
  • FIG. 1 shows a metallurgical vessel 10, which receives melt 140 from a ladle 100 and discharges it through an outflow opening 120 into an oscillating mold 130.
  • the subsequent strand guide is not shown here.
  • a stopper rod 205 is arranged, which is connected to a stopper rod mechanism 210. Attached to the stopper rod 205 or stopper rod mechanism 210 is a sensor 220 which transmits oscillations of the stopper rod 205 or stopper rod mechanism 21 0, which occur in the melt 140 due to vortex formation, as signals to a controller 230.
  • a slide 300 which can also be used as emergency slide, arranged. The drain opening 120 can thus be closed either with the stopper rod 205 or with the slider 300.
  • the vortex effect which occurs during the outflow of the melt 140 from the metallurgical vessel 110 causes vibrations in the melt 140.
  • the vibrations occurring in the melt 140 are transmitted to the stopper rod 205, which is located in the melt 140, and thus to the stopper rod mechanism 210 , Since the stopper rod 205 is located directly and centrally above the drainage port 120, timely and direct transmission of the vibrations as a primary signal to the stopper rod 205 and the stopper rod mechanism 210 is provided.
  • These vibrations are detected by a sensor 220, which is arranged on the stopper rod 205 or the stopper rod mechanism 210, and forwarded as a signal to a control device 230.
  • the controller 230 compares the signal with a predetermined threshold.
  • the control device If the current amplitude and / or frequency of the oscillations represented by the signal exceeds the predetermined threshold value, the control device generates an output signal which activates the shutter. It will either the stopper rod 205 or a Slider 300 controlled below the drain opening 1 20, which cause the closure of the drain opening 120. Since there is a risk that the slag and melt will mix as from the occurrence of the vortex effect, a targeted, early and immediate lowering of the stopper rod 205 or the targeted, timely and rapid blocking of the steel flow via the slide 300 below the drain opening 120 is necessary. In the present invention, the timing for the closure of the drain opening is required to achieve optimum separation between melt and slag. Exactly this point in time is determined by the vortex effect, which always occurs when the metallurgical vessel 1 10 is to be emptied at the end of the casting or when the vessel 1 10 is changed.

Abstract

L'invention concerne un dispositif (200) et un procédé pour obturer une bonde (120) d'une cuve métallurgique (110). Ledit dispositif comprend une quenouille (205) disposée dans la cuve au-dessus de la bonde (120) pour obturer la bonde (120), un mécanisme (210) destiné à lever et abaisser la quenouille (205), et un capteur (220) destiné à détecter des oscillations de la quenouille (205) ou du mécanisme (210). Pour permettre de connaître aussi tôt que possible l'instant de fermeture de la bonde de la cuve métallurgique et d'obtenir une séparation optimale entre le métal en fusion et le laitier, le dispositif (200) comprend un dispositif de commande (230) destiné à commander un dispositif de fermeture de la bonde (120) de la cuve, en fonction des oscillations détectées par le capteur (220) sur la quenouille (205) ou sur le mécanisme (210).
