Definitions

  • the invention relates to a keystone set for a vault made of refractory stones, consisting of two form-fitting adapter stones that can be connected to the refractory stones and a wedge-shaped keystone that is to be closed in the Space between the adapter blocks can be inserted axially, the adapter stones and the keystone in one Joint bed made of mortar are used and made Magnesia stones exist.
  • - Fireproof stone vault can be found in industrial ovens, e.g. B. in the field of Distribution bridge above a burner of a lime shaft furnace.
  • CH-PS 453 586 is a furnace lining for rotary kilns known from wedge-shaped stones and between the Stones arranged metal sheets is built.
  • the Metal sheets have a sheet thickness between 0.8 and 1 mm and have beads produced by deep drawing, which engage in grooves in the adjacent refractory bricks.
  • the Metal sheets serve as joint binders.
  • the refractory bricks are not laid in the mortar bed, but only with the interposition of the metal sheets with each other connected.
  • the invention has for its object a keystone set specify the keystone in the full joint bed can be set and which the vault pressure at takes up even pressure distribution.
  • the invention teaches that the im installed condition mutually supported connection surfaces the adapter stones and the keystone as flat, stepless surfaces are formed and assigned to each other Have grooves that appear after inserting the Complete the keystone into an open channel on the front, and that the channels each have a front insertable solid coupling rod made of a non-alloy carbon steel record, tape.
  • MA spinel stones are suitable, Magnesia chronite stones, magnesia zircon stones and the like.
  • the mutually assigned grooves complement each other to form bores and have the appropriate inserted in the holes Coupling rods with a circular cross section Diameter from 10 to 15 mm.
  • the invention teaches that the Keystone is divided and made of two keystone halves which, when installed, on level, stepless contact surfaces are supported against each other.
  • the contact surfaces also have mutually associated Grooves on, which become an open end channel supplement that receives a coupling rod.
  • the Arch pressure evenly on the keystone or Keystone halves transferable.
  • the setting of the keystone or the keystone halves are fully full Joint bed, whereby an even application of mortar ensures is and annoying partial densifications of Mortar accumulations do not occur. Assembly errors are thereby excluded.
  • the coupling rods secure the Keystone or the keystone halves against Moving under the effect of the arch pressure. Under the Operating temperature of the furnace, during heating and Burning process, it comes through reaction of the components the metallic coupling rod and the magnesia stones a fixed connection in the form of a ferritic Connection zone between the coupling rod and the adjacent magnesia material.
  • connection zone is created through diffusion processes and acts on a comparison to the cross section of the coupling rods much larger Area of magnesia stones.
  • the connecting zone causes a firm connection and secure locking of the Keystone set of stones. A slip in itself changing vault pressure is excluded and a uniform introduction of the vault pressure guaranteed.
  • the adapter stones can be on the keystone facing outside a substantially radial have trained projection, the manner of a Tongue / groove connection in a positive manner in a groove on the Outside of an adjacent stone of the vault intervenes. It is understood that on the outside of the Adapter stones can also be provided with a groove a protrusion formed on the neighboring stone interacts positively.
  • the vault is made of wedge-shaped refractory stones 1 built up over substantially radial Interlock groove / tongue elements 2 in a form-fitting manner.
  • the Keystone set consists of two form-fitting to this Stones 1 connectable adapter stones 3 and one, in Embodiment split, wedge-shaped Keystone 4, which is in the space to be closed between the Adapter blocks 3 can be used axially.
  • adapter stones 3 and magnesia stones are used as keystone 4.
  • step-free surfaces are formed and mutually assigned grooves 6 have after the insertion of the keystone add a channel 7 open at the front.
  • metallic coupling rods 8 can be inserted at the front.
  • the divided keystone 4 consists of two identical keystone halves 4 ', 4' 'built in Condition also on flat, stepless contact surfaces are supported against each other.
  • the contact surfaces point also correlated grooves on each other complete a channel 7 that is open at the end, the one metallic coupling rod that can be inserted at the front 8 records.
  • they complement one another assigned grooves 6 to a bore that extends axially extends the entire width of the stones.
  • the bore points preferably a diameter of 12 mm.
  • the Coupling rods 8 are solidly designed as round bolts and are made of an unalloyed carbon steel.
  • the Adapter blocks in the manner of a tongue and groove connection 2 to the adjacent stones 1 of the vault connected.
  • the adapter stones 3 On the outside of the keystone 4 have the adapter stones 3 on their outside substantially radially oriented projection 9, the into a groove 10 on the outside of the adjacent stone 1 of the vault engages. It is understood that the Tongue / groove connection 2 can also be designed differently.
  • the keystone halves 4 ', 4' ' are fully integrated into one full joint bed made of mortar. Then be the coupling rods 8 into the channels 7 that are open at the end introduced. During the heating and burning process of the Components of the furnace react metallic coupling rods 8 and 3 magnesia stones, 4 ', 4' '. There is a firm connection between the Coupling rods 8 and the adjacent magnesia stones 3, 4 ', 4' ', which form a ferritic transition zone can be traced back. Through the coupling rods 8 are the keystone halves 4 ', 4' 'against slipping secured and able to different sizes To record vault pressures. The vault pressure is over the flat, stepless pads 5 with a uniform Pressure distribution in the keystone 4 or its keystone halves 4 ', 4' 'initiated.
