Definitions

  • the invention relates to a coke oven blanket made of several layers of refractory material, a layer of refractory concrete being provided above a layer consisting of refractory stones and covering the furnace chamber.
  • the invention further relates to a method for producing such coke oven blankets.
  • Usual coke oven ceilings consist of several layers of refractory bricks. The following structure often occurs: First of all, shaped silica bricks, above them fireclay normal bricks, above fire-light normal bricks, above insulating normal bricks. The top layer of the furnace roof is formed by red bricks.
  • the generic coke oven blanket is known from DE-A-32 42 998. It comprises an additional recuperation layer made of molded parts, which contains an additional circulation system for a heat exchange medium, which require increased material and assembly costs.
  • Another generic coke oven blanket is known from DE-A-34 26 149. It contains an alloyed stainless steel foil that acts as a barrier layer and is protected from mechanical damage during laying and during operation by two thin screed layers made of refractory concrete. Both the assembly effort and the material expenditure are similarly high as with coke oven ceilings, which consist exclusively of refractory concrete layers.
  • the invention is therefore based on the objects of providing a coke oven blanket with low material and construction costs and a method for producing such coke oven blankets.
  • refractory concretes which have a content of Al2O3 from 25 to 28%, a content of SiO2 from 30 to 50% and a content of Fe2O3 from 8 to Have 12% and their production is carried out according to claim 8 in that the introduction and the post-treatment of the various refractory concrete layers is carried out according to the heating draft temperatures.
  • Refractory materials are materials that can withstand temperatures from 1500 ° C to 1700 ° C. This differs between fire-resistant materials (up to 1500 ° C) and high-fire-resistant materials (from 1700 ° C).
  • Refractory concretes are unshaped masses with a hydraulic bond cement, which may become a ceramic bond at higher temperatures.
  • the refractory concrete can be introduced as ramming compounds. The ramming compounds advantageously make the production of special shapes unnecessary.
  • the refractory concretes according to the invention are preferably used between the firebrick layer and the uppermost stone layer of the furnace roof. Surprisingly, it turns out that the assembly effort and the material expenditure are lower than in the case of coke oven ceilings according to the prior art, the temperature behavior in the oven ceiling being as good as in oven ceilings which consist solely or predominantly of refractory bricks or contain a recuperation layer. In addition, the furnace ceilings with the refractory concrete according to the invention prove to be very tight against gas penetration.
  • the oven has a width of 390 to 430 mm.
  • Silica shaped stones 2 are provided at the bottom of the furnace ceiling.
  • the silica stones are refractory bricks and form a layer with a height of 220 mm in the exemplary embodiment.
  • the firebrick normal bricks lie over the silica bricks 3.
  • the firebrick normal bricks are again refractory bricks. In contrast to a conventional furnace ceiling with two layers of firebricks, only one layer of firebricks 3 is provided.
  • the refractory bricks made of firebricks are 70 mm thick.
  • the top of the furnace is closed by a red brick layer 7.
  • the red brick layer is also referred to as the rolled brick layer.
  • red brick layer 7 which has a conventional thickness of 130 mm
  • firebrick layer 3 the following structure being obtained from bottom to top:
  • the lower layer of lightweight lightweight concrete is 200 mm thick and 4, the upper is 100 mm thick and labeled 6. In between is the insulating concrete layer 5 with a thickness of 250 mm.
  • the fire lightweight concrete layer has the following specification:
  • the insulating concrete layer has the following specification:
  • An expansion joint of 10 mm is provided between the refractory concrete area and the other refractory bricks.
  • the expansion joint is filled with a silicate fiber material (3/4 inch ceramic felt) and can be replanted if gas escapes.
  • the silicate layer is designated 8.
  • Such an expansion joint ensures that no expansion damage occurs when the masonry is heated.
  • the aluminum foil has a considerable insulating effect and sealing effect against gas penetration.
  • the furnace walls are set up normally and the chamber cover stones are inserted as usual.
  • the chamotte normal stone layer 3 is placed over it.
  • the small heating walls consist of firebrick or prefabricated components.
  • the refractory concretes are applied in layers in the free fields between the filling hole shafts and head mirrors in the direction of the chamber axis and the heating walls in the direction of the battery axis. This is done by stamping the masses.
  • the lower layer of lightweight lightweight concrete 4 is placed at a heating temperature of approx. 55 ° C.
  • the insulating concrete 5 and the top layer of lightweight lightweight concrete 6 are placed at a heating temperature of approx. 900 ° C. All refractory concrete layers are kept moist for at least 30 hours after application.
  • the temperatures and the other parameters of the insertion are largely determined by the expansion behavior of the silica material used in the substructure.
  • the furnace roof is closed by inserting the brick roll layer.
  • the installation of the ceiling according to the invention results in savings of approximately 50% of the costs.
