Definitions

  • the invention relates to a sealing system for a plug rod in one Refractory ceramic body designed to close an opening of a metallurgical vessel for holding melts in the liquid phase, especially for the continuous casting of liquid metals.
  • Metallurgical vessels for pouring liquid melts into a mold have a body formed by a refractory ceramic lockable opening for the discharge of liquid melt.
  • the flow rate of the liquid melt through the opening of the vessel is activated a plug rod attached to the refractory body adjustable.
  • the invention is based on the object of providing a sealing system of the type mentioned at the outset which enables the plug rod to be sealed simply, inexpensively and securely with respect to the refractory body with a long service life even at high temperatures.
  • the body has a recess for receiving a deformable sealing element and a sleeve, wherein the sealing of the stopper rod relative to the body, the sealing element with the sleeve on the stopper rod in the recess of the body by way of a gland seal is compressible.
  • Sealing element and sleeve thus create an optimal sealing effect, especially since this is in the recess of the refractory body as well Fit the plug rod.
  • the sealing element and the sleeve are through the body made of refractory ceramic before direct contact protected by liquid melt, so that the sealing system even at high Temperatures have a long service life.
  • the plug rod has at least in the recess of the refractory body subsequent area on an external thread, so that the sealing element over the sleeve with a nut which can be arranged on the stopper rod in the Recess of the body is compressible.
  • This is advantageous sealing system according to the invention by adjusting the nut retensionable.
  • the sealing element For sealing the stopper rod against that made of refractory ceramic trained body is the sealing element and adjacent to the sleeve in the recess of the body inserted and screwed on the nut the plug rod of the sealing element over the sleeve in the recess compressed. This is an axial on the sleeve on the sealing element acting pressure force, which increases the sealing effect. Due to the adjustable Nut on the plug rod can be tightened and the sealing system thus adapt to different tightness requirements. Threads the sealing element, on the sleeve or on the refractory body, so that damage, especially of the sealing element, during assembly be avoided.
  • the sealing element and the sleeve are advantageously formed in one piece, so that the number of components to be used and thus the cost of Manufacturing and assembly can be reduced.
  • the sealing element is advantageously a sealing ring which preferably consists of graphite, so that the sealing element by acting a corresponding force more easily deformed and a particularly effective Sealing effect can be achieved.
  • the sealing element when replacing the Sealing system or when replacing the plug rod, the sealing element can be removed more easily, so that stand and processing times are further reduced become.
  • the recess is tapered in the body made of refractory ceramic formed and the sealing ring has a corresponding corresponding trained outer contour, so that it fits as far as possible in the Recess can be used.
  • the conical shape of the so formed Sealing seat forms together with an appropriately shaped one Sealing element a long sealing distance, and thus prevents Leaks in the area of the seal.
  • this is Sealing element pressed over the sleeve in the recess.
  • the sleeve has a contact surface adapted to the sealing element, the one uniformly high force transmission acting axially on the sealing element enables.
  • the sealing ring advantageously has a trapezoidal cross section, so that the sealing ring fits as closely as possible into the tapered Recess of the body made of refractory ceramic as well as to the Contact surface of the sleeve fits and so the sealing effect of the invention Sealing system further increased.
  • the sleeve is advantageously tapered formed so that the sleeve in the recess when force is applied pressed.
  • the in Figs. 1, 2 and 3 shown fumigable plug rod 1 is present in a body 14 made of refractory ceramic with a Bayonet lock attached.
  • a body 14 made of refractory ceramic in a recess a pressed part 2 from a piece of metal pipe arranged, which is provided with two opposing pins 3, which protrudes the inner and outer jacket of the tube 2 on this are attached by welding, as shown in FIGS. 4 and 5 in detail detect.
  • the outer end of the tube 2 protruding through the outer jacket Pins 3 is used to anchor the tube 2 within the body 14.
  • the tubular press part 2 is made with one Plastic-made ring 12 sealed against the body 14 and in the Body 14 stored.
  • the plug rod 1 has an external thread 13 over wide areas provided, at the thread runout directly on the part of Plug rod 1 trained bayonet groove of the bayonet catch for Attachment of the plug rod 1 in the body 14 connects. With the Bayonet lock can the plug rod 1 in the manner of a quick release attached and detached from the body 14 very simply and quickly become.
  • this has Sealing system made of graphite, a trapezoidal Sealing ring 4 having a cross section, as shown in FIGS. 1 and 8 shown, on which a conical in the direction of the sealing ring 4 tapered sleeve 5, in the present case a seamless precision tube, then, as shown in Figs. 1 and 7.
  • the sealing ring 4 and the abutting sleeve 5 in a suitably designed, tapered recess in the Body 14 can be used.
  • the sealing ring 4 By a on the thread 13 on the plug rod 1st arranged nut 7 is the sealing ring 4 via a washer 6 and the sleeve 5 in the recess of the body 14 in the manner of a gland seal compressible, the sealing system thus formed via the nut 7 can be retightened, especially with an exact tightening torque, for example in a range from 75 to 90 Nm.
  • the sealing ring 4 has thereby an outer contour, which in the tapered recess can be used as precisely as possible.
  • the sleeve 5 in the the sealing ring 4 adjacent area is slightly tapered and provides a bearing surface for the sealing ring 4, which when tightening the Nut 7 a uniformly high, axially acting on the sealing ring 4 Force application to seal the plug rod 1 against the body 14 enables.
  • the plug rod 1 has two spherical disks 9 and conical sockets 10, which by means of a nut 8 on the thread 13 on the plug rod in Different positions can be arranged and for example to attach the Serve plug rod on an actuator.
  • 1 shows that the fumigable plug rod 1 at the end opposite the body 14 has a screw-in bracket 11, through which the one continuous Bore-containing plug rod 1 with a process medium, for example Oxygen or the like, can be supplied.
  • a process medium for example Oxygen or the like
  • the Sealing ring 4 has a tapered recess in The outer contour corresponding to the body 14 is made of graphite formed and deformed by the adjustable by turning the nut 7 Application of force. This creates a particularly high-quality sealing effect.
  • the Sleeve 6 has a conical chamfer in the direction of the sealing seat, which Tilting when inserting or removing the sealing system avoids. By tightening the nut 7, the force with which the sealing ring 4 is in the seal seat is pressed, adjustable.
  • the sealing system By relaxing the nut 7, the sealing system is released.
  • the disc 6, the sleeve 5 and the sealing ring 4 are with the plug rod 1 from the Removal of the body 14 removed.
  • the bayonet catch becomes Fastening or for releasing the plug rod 1 on or from the body 14 opened by rotating the plug rod 1 about its longitudinal axis or closed.
