Definitions
- the invention relates to a support device for supporting heated material in a heat treatment furnace, with a cooled support tube and at least one rider placed on it, on which the heated material can be supported in the furnace.
- Supporting devices of this type are used primarily in push furnaces and walking beam furnaces in rolling mills.
- the riders are shaped pieces, preferably made of highly heat-resistant cast.
- the invention has for its object to ensure permanent and effective insulation of the cooled support tube in the rider area by special training of the rider of the support device mentioned.
- the rider has a supporting web part and shell-shaped side legs formed on both sides thereof, which enclose part of the circumference of the cooled support tube at a distance, and that insulating chambers are formed between the support tube and the inner sides of the side legs.
- the insulating chambers which are preferably filled with a heat-insulating material, for example with shaped pieces made of ceramic fiber material with high thermal resistance, are covered by the shell-shaped side legs and are therefore also protected against the ingress of liquid slag.
- the heat-insulating material accommodated in the insulation chambers is practically protected on all sides during operation, secured against falling off and, due to its arrangement as an intermediate layer between the cooled support tube and the side legs surrounding it at a distance, has an excellent thermal insulation effect.
- Inevitable thermal bridges from the supporting web part to the molded-on side legs can be minimized in a further development of the invention in that the transitions from the outside of the side legs to the supporting web part are provided with longitudinal fillets, which are filled with a highly heat-resistant and relatively poorly heat-conducting ceramic casting compound.
- the rider consisting of the central web and the cup-shaped side legs is preferably designed as a one-piece casting.
- the web part is designed as a central web and has projecting supporting ribs up and down over the attachment points of the symmetrically arranged side legs.
- the rider's symmetrical design minimizes any thermal stress.
- the cup-shaped side legs intended to hold holding pieces attached to the support tube.
- the holding pieces that fix the riders in the longitudinal direction are thus included in the insulation and covered by the shell-shaped legs, as a result of which thermal bridges from the cooled support tube to the side legs are avoided.
- the support device is further developed in that at least one T-profile is attached to the top of the support tube in such a way that its central web points upwards and runs parallel to the support tube axis, and that the rider has one to the central web of the T-profile Complementally designed downwardly open groove and a transverse web delimiting the groove and can be attached to the support tube via the T-profile.
- the support device is further developed in that at least one T-profile is attached to the top of the support tube in such a way that its central web points upwards and runs parallel to the support tube axis, and that the rider has one to the central web of the T-profile Complementally designed downwardly open groove and a transverse web delimiting the groove and can be attached to the support tube via the T-profile.
- cross-sectionally identical T-profiles are aligned in pairs at a distance one behind the other in a vertical plane and are firmly connected to the support tube and that the crossbar of the rider engages in the free space between the two T-profiles with slight play and two for receiving the The central webs of the T-profiles limited suitable grooves in the tab.
- the T-profile which engages in the rider's grooves with the center bar, the center bar of which strikes the rider - cross bar, transmits all horizontal forces that act on the rider during transport of the heat to the support tube.
- the rider 1 which is symmetrical with respect to a vertical longitudinal plane, has a supporting web part 10 that supports the heat material and two shell-shaped side legs 2 that extend approximately halfway up the web part 10 placed on a support tube 3.
- the two side legs enclose at a distance the upper part of the circumference of the cooled support tube 3 and extend down to close to an insulation 8 which is inherent in the support tube.
- Isolation chambers 4 are formed between the insides of the two shell-shaped legs 2, the lower support rib of the web part 10 and the adjacent section of the outer circumference of the support tube 3, in each of which insulation molded pieces 4 'made of ceramic fiber material are embedded (FIG. 1).
- On the support tubes 3 welded laterally holding pieces 5 are arranged in recesses 6 of the side legs 2 of the rider 1. The spaces between the holding pieces 5 and the recess 6 are also filled with ceramic fibers, so that thermal bridges to the legs 2 and thus to the furnace interior are interrupted.
- the transitions from the outer sides of the side legs 2 to the supporting web part 10 are provided with longitudinal grooves 9. These are filled with a suitable ceramic casting compound 9 '.
- the insulation 4 ′ minimizes the heat transfer or heat losses via the outer surfaces of the two shell-shaped legs 2 to the cooled support tube 3 at the locations above the support tube insulation 8.
- the exemplary embodiment of the carrying device shown in FIGS. 3 and 4 is particularly advantageous for round cooled carrying tubes 30.
- the rider 11 is not placed directly on the support tube 30 via a support rib projecting downward toward the support tube, but indirectly via T-profiles 12a and 12b.
- the two T-profiles are aligned along an axial plane 13 of the support tube 30 and welded onto the upper side thereof.
- the central webs 14 of the T-profiles 12a and 12b point upwards, while their legs are arranged in a horizontal plane.
- the associated tab 11 has two grooves 15a, 15b which are complementary to the central webs 14 of the T-profiles and which are delimited on the inside by a transverse web 16 (FIG. 4).
- the width of the transverse web 16 is dimensioned such that it can be inserted with a certain amount of play into the gap between the T-profiles 12a and 12b or their central webs 14.
- the rider 11 attached to the support tube 30 or the T-profiles 12a and 12b is therefore positively fixed by the groove walls and the crossbar 16 via the T-profiles on the support tube 30 such that horizontal forces from the rider 11 to the support tube 30 in all directions can be transferred.
- the length of the T-profiles 12a and 12b is not critical, as is the position and arrangement of the crossbar 16 delimiting at least one groove 15 on the rider 11.
- the crossbar 16 can also be arranged at the rider end and only limit one groove 15.
- the profile section forming the legs of the T-profile fulfills a support function similar to that of the downward-pointing support rib of the rider 1 in FIG. 1.
- the surface sections of the groove close to the groove that are supported on the legs of the T-profile Rider 11 lie in a horizontal plane and merge into the inner sides of the side legs 2 of the rider 11 which also delimit the insulating chambers 4 in this exemplary embodiment. Further out, the inner surfaces of the side legs 2 are curved in accordance with the shape of the support tube 30 or the heat-insulating material 4 ′ contained in the insulating chambers 4.
- the insulating material 4 ′ contained in the insulating chambers 4 is preferably selected as a function of the surface temperature permissible for the material of the tab 11. If the surface temperature is to be largely the same, a material of high thermal insulation, e.g., in a cooler part of the furnace in which the support device is used, is used. the above ceramic fiber material is used, while in a hotter part of the furnace a material of lower thermal insulation, e.g. a light ceramic mass, a heavy refractory mass or fired ceramic parts can be used.
