Definitions

  • the invention relates to door plugs for coke oven doors, which are made of ceramic material and are held at a distance from the coke oven door. In the operating state, the plugs then protrude into the furnace chamber and hold the furnace filling at a certain distance from the door body, the door body being pressed against the door frame of the furnace with a locking device during the coking process.
  • the metallic door stopper is the door stopper known from German Patent 23 83 63.
  • This door stopper is formed by an adjustable protective shield attached to the rear wall of the coke oven door, which is connected to the rear of the door via articulated intermediate elements and can move in relation to the door.
  • the invention has for its object to avoid the operating difficulties of current metallic door plugs.
  • the invention again uses ceramic material by using ceramic plates with a thickness of 35 to 120 mm.
  • ceramic material is suitable.
  • a hydraulically binding refractory concrete is provided.
  • the essential components of this refractory concrete are aluminum oxide, silicon oxide and iron oxide.
  • the proportion of aluminum oxide (A1 2 0 3 ) is 40-55%, the proportion of silicon oxide (Si0 2 ) between 40 and 50%, the proportion of iron oxide (Fe 2 0 3 ) between 0.5 and 1.5%.
  • a ratio of thickness to plate width of 1: 3 to 1:20 can result.
  • the ceramic plate consists of interchangeable elements.
  • the interchangeable elements are optionally arranged one above the other and are each held in a metal frame.
  • the metal frames are attached individually, e.g. with welded carrier iron. This allows simple and easy replacement of the ceramic elements in the event of damage.
  • the metal support frames are preferably fastened to the door in an adjustable manner. This is done by means of suitable carrier iron or counter carrier, which are screwed or wedged together. In the case of screwing, elongated holes are provided for adjustment.
  • the door leaf of the coke oven door is expediently provided with an insulating layer, which heats up the door and is associated with high heat radiation, ie heat loss and thermal stress on operators.
  • the insulation layer is 50-100 mm thick.
  • the ceramic plate protrudes into the furnace chamber to the extent that the furnace filling is retained as much as with conventional ceramic plugs.
  • the adjustability also allows the ceramic plates to be taken back and the associated enlargement of the furnace space.
  • the respective position of the ceramic plate can, however, also result from an optimized arrangement with respect to the last heating draft in the coke oven walls.
  • the desired large gas collecting space is created behind the metallic support frame in the ceramic plate according to the invention, i.e. between the ceramic plate and the insulating layer.
  • Figure 1 shows a cross section through a door stopper according to the invention with a coke oven door.
  • 1 denotes a ceramic plate, the ceramic plate is held adjustable in a heat-resistant steel frame 2 with three welded-on carrying arms 3.
  • Retaining anchors 4 are formed in the ceramic front plate as connecting elements to the metal frame 2.
  • the holding anchors 4 are shown in broken lines.
  • the ceramic material is either: or:
  • the straps are held on counter straps 5, which in turn are screwed to the coke oven door.
  • the counter brackets 5 have 1 elongated holes 9 for adjusting the ceramic front plate.
  • the mounting brackets 3 are fastened to the counter bracket 5 by means of screws or wedges.
  • the coke oven door 8 is protected with an insulating layer 7 against excessive heat load.
  • the insulating layer 7 is again made of ceramic material. When using ceramic material, this is molded and pre preferably secured by retaining anchors 10. The holding anchors 10 are again shown in broken lines.
  • a door stopper is composed of a plurality of front plates 1 arranged one above the other.
  • the carrier iron 3 and counter carrier 5 are located at the top and bottom of the metal frame belonging to the ceramic front plates 1.
  • this allows the use of a counter support 5 at the same time for two opposite support bars 3.
  • One of the three fastening points is arranged on the center line of the coke oven door. The other two are on either side of the center line. This is shown in Figure 3.
  • attachment points can also be selected. These are then located at the four corners of the panels. Each support iron and counter support iron can form the attachment for two adjacent corners of two adjacent ceramic plates.
  • FIG. 4 shows a section through a fastening point with two opposing carrying bars 3 and a counter carrying bar 5.
  • the gas channel between the stopper and the door is closed with mineral wool or the like. This wool is removed from the mold after it has been sufficiently heated.
  • the ceramic signs are provided with plates 20, which are each fastened at four corners.
  • Each carrying iron also forms a fastening for a plate 20 arranged above and underneath. While the fastening to the upper plate corners takes place with a positive and positive connection, the fastening to the lower plate corners allows displacement in longitudinal slots in accordance with the thermal expansion. The associated fastening screws are loose. A complete loosening is prevented by lock nuts.
  • the plates are drawn in at 23 below and the fastening points are covered by edge stones 24.
  • the edge stones 24 are also held by the carrying iron 21.
