Definitions

  • the invention relates to a holding device for molded parts and / or mats made of ceramic fiber material, which are attached to the inside of the metallic furnace shell of an industrial furnace, consisting of rod-shaped, metallic anchors, which are held on the metallic furnace shell and engage in the mats and / or shaped parts, in particular from Steel which has ceramic abutments on its end parts facing the inside of the furnace, engaging on the inside of the mats and / or moldings and clamping the latter to the metallic furnace jacket, with the anchors thermally insulating, fireproof extensions towards the metallic furnace jacket towards the metallic furnace jacket made of ceramic are arranged, which are profiled tubular and are held and penetrated by the anchors.
  • Such a holding device is known from US-A 35 23 395.
  • the holding device consists of a metallic anchor and a fire-resistant extension provided with a threaded bore, which carries an abutment at its inside end.
  • the metallic anchor runs only over a fraction of the thickness of the molded parts or mats, which are pressed against the inner wall of the furnace, while only the ceramic extension with the abutment lying relatively on the inside of the furnace runs over the rest of the length of the entire holding device. This means that bending stresses that occur only have to be partially absorbed by the metallic anchor, but also to a large extent by the ceramic extension element.
  • the ceramic part it is necessary for the ceramic part to be formed with an internal threaded bore, which is complex in terms of production technology.
  • the object of the invention is a holding device Generic type to create, in which the bending loads can be absorbed essentially by the metallic anchor and a significant increase in the bending strength of the anchor can be achieved without increasing the cross section of the anchor cross-section.
  • the abutments are approximately bell-shaped and the anchors engage with their end parts facing the furnace interior through the perforated bottoms of the bell-shaped abutments in the latter, so that the anchor extends from the furnace shell to the furnace interior; that the tubular profiled extensions each have a, in particular molded, axially supporting flange on the bottom of each abutment and are clamped to the bottom of each abutment by means of the anchor or are each formed integrally with the abutment; and that the bell-shaped abutments are closed with plugs made of refractory material.
  • the metallic anchors range from the metallic furnace jacket to the inside of the furnace the anchors reach through both the extensions and the perforated bottoms of the bell-shaped abutments. As a result, essentially all bending stresses that occur can be absorbed by the metallic anchor. Characterized in that the anchor penetrates the thermally insulating refractory extensions, the anchor is largely protected against thermal stress even in the penetration area. As a result, it is possible to choose a relatively small cross-section of the anchor and still achieve a high bending strength.
  • the extensions extend from the abutments to the temperature ranges of the thermally insulating furnace lining heated to operating temperature of approximately 600 ° C. or less.
  • the extensions end at a distance from the furnace jacket.
  • the flanges of the extensions are axially supported on the inside of the abutment bottoms and are strained to the abutment bottoms by means of the anchors.
  • the anchors are screwed axially adjustable in threaded holes arranged on the furnace jacket.
  • the bottoms of the approximately bell-shaped abutments are at least non-positively clamped between the flanges of the extensions and axially effective anchor counter-bearings.
  • the flanges are axially supported on the outside of the abutment floors, the axially effective anchor counter bearings are clamped onto the inside of the abutment floors and that effective tensioning devices are arranged on the anchors in the direction of the flanges of the extensions.
  • All embodiments have in common that a metallic furnace jacket 1, in particular made of steel, is coated on the inside with mats 2 and a large number of molded parts 3 made of ceramic fiber material arranged next to one another and one above the other.
  • a plurality of bolt-shaped anchors 4 made of steel and which engage in the mats 2 and molded parts 3 strive to hold them on the furnace jacket 1.
  • the armatures 4 are welded to the furnace jacket 1 with their one end part.
  • An abutment 5 made of hard ceramic is detachably fastened to the free end parts of the armatures 4, which are directed towards the furnace interior, each of which has an integrally formed, circumferential, radially outwardly striving flange 6, which is supported axially on the side of a molded part 3 facing the furnace interior .
  • the abutments 5 have an approximately bell-shaped shape and the anchors 4 engage with their free end parts through the perforated bottoms 7 of the bell-shaped abutments 5.
  • a tubular profiled extension 8 is attached to the armature 4, which can extend into the mats 2, but end at a distance from the furnace jacket 1.
  • each of the extensions 8 has an integrally formed, radially outwardly directed circumferential flange 9.
  • the flange 9 of each extension 8 is positively supported on the inside of the abutment base 7.
  • ceramic fibers and / or refractory mortar can be provided between the support points.
  • the anchors 4 end with external thread zones, onto each of which a screw nut 10 is screwed, by means of which on the one hand the flange 9 on the inside of the abutment base 7 and on the other hand via the abutment 5 the molded parts 3 and the mats 2 to the Be tensioned inside the furnace jacket 1.
  • a washer 11 which distributes the clamping force uniformly over the entire surface of the flange 9 can be arranged.
  • the armature 4 is designed as a cap screw, the head of which is supported on the flange 9 via a washer 11, while the screw shaft having the external thread is screwed into a threaded bore 12 in the furnace jacket 1.
  • the threaded bore 12 can be formed by a threaded bushing or screw nut welded onto the furnace jacket 1. It is It is advantageous to provide a through-bore arranged coaxially with the threaded bore 12 in the furnace jacket 1 and a key extension 13 at the free end of the screw shaft so that the cap screw can be tightened through the through-bore of the furnace jacket 1.
  • the flange 9 of the extension 8 is supported on the outside of the abutment bottom 7. Furthermore, a screw nut 14 is arranged on the shaft of the anchor 4 designed as a cap screw, by means of which the flange 9 of the extension 8 is clamped to the outside of the abutment base, after which the abutment base 7 is then clamped without play between the flange 9 and the head of the anchor 4 , whereby a kinking of the abutment 5 is excluded from the extension 8.
  • the abutment 5 and the extension 8 are each formed in one piece.
