Definitions

  • the invention relates to a converter system with between the hat of a tiltable Converter and the mouth of a flue gas chimney provided sealing ring, wherein Drives are provided with which the sealing ring is so far from the converter hat can be moved away that the converter can be tilted freely.
  • Converters for steel production are usually with a water-cooled Refrigerated fireplace equipped to the process gases emerging at the mouth record and derive.
  • the converter mouth is from the inlet opening of the Cooling stoves spaced around the vessel for charging and emptying underneath to be able to move past the chimney opening.
  • Labyrinth-like aprons are expensive because of the required cooling, they are of limited effect due to the remaining gaps and are also bad accessible.
  • the invention has, with knowledge of the above. Difficulties set with constructively simple means the split converter and chimney during the Company to close tightly and, moreover, to create an opportunity Establish a gas-tight connection between the chimney and converter and thus the system also operate under overpressure.
  • the sealing ring is designed as a sleeve which holds the flue gas fireplace from outside.
  • the mouth of the sleeve is in the closed position on Converter hat can be leaned on.
  • the sleeve has vertical separating cuts, with a Locking ring arises, which consists of two or more mutually movable Sub-segments is composed.
  • the individual segments have one Inner radius that corresponds to the outer radius of the lower part of the chimney. As soon as the sub-segments of the locking ring lie against the chimney wall, the Ring tightly closed.
  • the horizontal distance between the individual segments can be predetermined Set range. This makes it possible to form the ring so that it over the edge of the converter can be lowered and when closing this also tightly embraced. This prevents air from being sucked into the converter gas will still escape from the system into the work area.
  • any intermediate positions can also be approached, always ensuring that the gap between the chimney and the locking ring is completely sealed.
  • the ring segments can also be attached so that they are at their upper edge are pivotally attached to a holding device and laterally upwards cupped into an open position or down into the closed position Position are moved. Suitable for the swivel movements can either Lifting rods are fixed or movable hydraulic cylinders are attached become.
  • the ring segments are made from water-cooled tubes that are tight are welded together.
  • the tubes can either be horizontal or be arranged vertically.
  • the cooling water is through movable connecting pipes passed, which are connected to the manifold of the pipe segments.
  • the lateral shifting device is actuated by means of hydraulic cylinders or else through mechanical devices such as thrust drive or lifting rod.
  • the necessary energy supply is provided by appropriate flexible supply lines.
  • the Devices are constructed and installed so that they are free from heat and slag are adequately protected.
  • the ring segments can be connected via a guide, which is for a controlled synchronous movement.
  • a guide which is for a controlled synchronous movement.
  • Guide rails with roller guides on the lower part of the chimney and on the locking ring therefor ensure that the components maintain their position relative to each other during the movements.
  • a converter 21 is shown, which has a converter hat 22 has, at the mouth of a collar 23 is provided.
  • a flue gas chimney 11 is provided above the converter 21 Muzzle 12 has.
  • a sealing ring 31 is arranged, which Has sleeve segments 33 and 34. This sealing ring can also be a larger one Show number of individual segments.
  • the sleeve segments 33, 34 have vertical separating cuts 35.
  • the sleeve segment 33 is connected to a drive 41 and the sleeve segment 34 is connected to a lifting device 42, by means of which the segments 33, 34 can be moved in the vertical direction. Furthermore, a guide element 51 is fastened to the segments 33, 34, which corresponds to a guide bar 52 which is fastened to a spacer tube 53.
  • the sleeve segments 33 and 34 are connected to one another via a joint 39 connected.
  • the sleeve segment 33 by a drive 41 and Sleeve segment 34 pivoted by a lifting device 42.
  • a locking device 43 through which the Openable sleeve segments and close to the collar 23 of the converter hat 22 can be pressed.
