Definitions
- the invention relates to a shielding module for a high-temperature furnace with the features of the preamble of claim 1.
- shielding module is understood to mean an arrangement which has a plurality of spaced-apart, parallel arrangements
- Shielding plates includes. This arrangement creates a shield against radiant heat through multiple reflection on the shielding plates and thus acts as insulation.
- high temperature is usually used when process temperatures above approx. 800 ° C are reached.
- a high-temperature furnace generally comprises a water-cooled furnace jacket, which forms an furnace chamber.
- Shielding modules are arranged within the furnace chamber, which enclose a process chamber.
- the process room forms the room that is intended for heat treatment.
- the shielding modules isolate the process room from the furnace jacket.
- shielding An arrangement of shielding modules is called shielding. Assembling a shield together with heating conductors is known as a hot zone. The use of a high temperature furnace is crucial for the temperature distribution, the purity and the energy consumption of high temperature processes.
- shielding packages form a shield of an oven, arranged in a multitude.
- the individual shielding modules are flanged to a support frame as a cylinder housing
- the object of the invention is therefore to provide an improved shielding module and an improved shielding formed from a plurality of shielding modules.
- the shielding module according to the invention for a high-temperature furnace comprises a package of shielding plates connected to one another.
- the attachment points on the base bodies are so for connecting
- Shielding modules are formed one below the other.
- shielding module according to the invention does not require any additional support structure in use.
- Shielding modules according to the invention can be used for self-supporting stable arrangements
- shielding modules according to the invention Another important advantage of the shielding modules according to the invention is that completely assembled shielding modules can be assembled into a shield at the installation site of the furnace.
- a complex and error-prone assembly of individual shielding plates on site can therefore be omitted. Repairing a shield is also much easier because defective shield modules can be easily replaced.
- the base body is preferably designed in the form of a box or a trough with a base plate and side walls, which side walls run essentially normal to a plane parallel to the shielding plates.
- the base plate is parallel to the shielding plates. This configuration of the base body gives it a particularly high rigidity, so that no undesired deformations occur when several base bodies are connected.
- attachment points can be formed particularly cheaply on the side walls.
- the side walls can be created by reshaping the base plate or can be placed on it.
- side walls point in a direction facing away from the shielding plates.
- the box formed by the base plate and side walls is open on the side facing away from the shielding plates (the “cold side”).
- the shielding plates preferably consist at least partially of one
- Refractory metal or a refractory metal alloy consist of all shielding plates consist of a refractory metal or a refractory metal alloy. It can be provided that, for example, a shielding plate facing the process space, that is to say with respect to an installation position, is made of tungsten or a tungsten alloy, and the other shielding plates are made of molybdenum or a molybdenum alloy.
- the shielding plates prefferably be made of refractory metal, and for example one or more of the shielding plates to be made of a heat-resistant steel on the cold side.
- Refractory metals in the context of the present invention are understood to mean the metals of the 4th group (titanium, zirconium and hafnium), the 5th group (vanadium, niobium, tantalum) and the 6th group (chromium, molybdenum, tungsten) of the periodic table and rhenium .
- Refractory metal alloys mean alloys with at least 50 at.% Of the element in question. Among other things, these materials have excellent dimensional stability with high
- the base body is preferably made of a heat-resistant alloy. Examples of suitable materials are - not exhaustively - the steels with the
- the base body can also be made from refractory metal or a refractory metal alloy be.
- the base body can be manufactured in a favorable manner from sheet metal of the materials mentioned.
- a wall thickness (corresponding to a sheet thickness) of the base body is, for example, 3-5 mm. This wall thickness contributes to a high bending stiffness of the base body.
- Dimensions of a typical shielding module can be, for example: a length between 450 mm and 600 mm, a width between 150 mm and 450 mm and a thickness between 80 mm and 100 mm. This information is in no way restrictive. It has been shown that with shielding modules this
- the base body has at least one side wall.
- the base body preferably has four side walls.
- Fastening points can be formed on one or more side walls. It is preferably provided that fastening points are formed on all side walls. This creates the possibility of shielding modules on all sides with other, equally trained
- the attachment points can, for example, be designed as bores or slots. Fasteners can be passed through holes or slots. As an alternative or in addition, fastening points can be implemented directly as fastening means: it is conceivable to form pins or the like on the side walls which permit fastening with base bodies of other shielding modules of the same design.
- the shielding modules are preferably rectangular in plan view.
- the shielding modules can be square.
- the shielding plates are preferably essentially flat, and so is the package formed by the shielding plates. However, deviations from this can also be provided. With curved shielding plates and a consequently curved package of shielding plates, for example, a shield - viewed in a cross section - composed of curve sections can be formed.
- shielding plates In terms of manufacturing technology, flat embodiments are preferred. “Flat” here means essentially flat as opposed to curved.
- the shielding plates can, however, have a structuring, for example a rib structure or a corrugated plate structure or a knob structure to increase the inherent rigidity of the shielding plates.
- Heating conductor suspension is formed.
- a heating conductor suspension allows at least one heating conductor to be attached.
- Feedthrough openings must be threaded. Rather, it is
- Heating conductor suspension integrally connected to the shielding module.
- the shielding module can have one or more heating conductor suspensions.
- the heating conductor suspension is connected to the shielding module on the base plate of the base body.
- a guide sleeve for accommodating the heating conductor suspension is particularly preferably formed on the base plate, by means of which the heating conductor suspension is supported over a greater length than merely over the thickness of the base plate.
- This preferred development ensures a rigid mounting of the heating conductor suspension on the base plate.
- the further development, according to which the heating conductor suspension is integrated in the shielding module considerably simplifies the installation of shielding modules compared to previously known solutions in which the heating conductor suspensions are fastened to a separate support structure. If the heating conductor suspensions are attached to a separate supporting structure, the shielding modules have to be positioned in a complex manner relative to the supporting structure during assembly in order to thread the heating conductor suspensions projecting from the supporting structure into the shielding modules. Or - just as complex - holes have to be drilled into the support structure that are in line with feedthrough openings in shielding modules.
- a notch is formed at least along one side edge of the package of shielding plates, which notch is suitable for engaging in a corresponding notch of a further shielding module.
- a notch is understood to mean a step in the package of shielding plates that arises from the fact that part of the shielding plates has a smaller lateral extent along a side edge of the package than another part of the
- Shielding plates The notch or step results in an overlap of shielding plates of the connected shielding modules when two shielding modules are connected. This avoids a gap at the joint. This is particularly important when connecting shielding modules at an angle to one another.
- a shielding module preferably has notches on two side edges.
- the notches on a shielding module are particularly preferably designed such that when shielding modules are connected along said side edges, the notch of one shielding module can engage in an opposite notching of the next shielding module.
- Protection is also sought for a shield for a high-temperature furnace consisting of a plurality of interconnected shield modules according to at least one of the preceding claims. If heating conductors are also attached to the shield, this arrangement is referred to as a heating insert, for which heating insert protection is also sought.
- the shielding modules are connected to one another via the fastening points mentioned at the beginning and form a self-supporting structure.
- a shield or a heating insert formed in this way only needs local punctiform when used in a high-temperature furnace
- the shielding modules are preferably connected to form a circumferentially closed contour.
- the shield formed by a plurality of shielding modules forms a ring which is closed along a circumferential direction.
- the contour has a polygonal shape in a cross section.
- the contour can also be circular in a cross section.
- Protection is also sought after for a high-temperature furnace with a large number of shielding modules according to at least one of the preceding claims, which limit a process space of the high-temperature furnace, with directly adjacent shielding modules being connected to one another via the attachment points of their base bodies.
- the interconnected shielding modules form a space with the sides facing each other. This room is called the process room of the high-temperature furnace.
- the process space preferably has an imaginary polygonal cross section.
- a self-supporting support structure of the plurality of shielding modules is formed by the interconnected base body of the plurality of shielding modules.
- Feed is formed. This means that a longitudinal axis of the high-temperature furnace runs essentially horizontally in contrast to vertical furnaces, in which the longitudinal axis runs vertically. Vertical ovens are used to support the
- Shielding is less demanding than horizontal furnaces because hardly any bending moments act on the shield.

- Figure 1 shows shielding modules 1 according to the prior art.
- a partial arrangement of shielding modules 1 is shown in cross section, corresponding, for example, to an arrangement in a high-temperature furnace.
- the shielding modules 1 consist of several spaced shielding plates 2, which are held together by bolts, pins or bolts 13.
- Shielding modules 1 are mounted on a support ring 17 via angles, brackets or similar fastening means and held in position.
- the support ring 17 is in turn arranged within a furnace jacket 12 of a high-temperature furnace.
- a heating conductor 8 can be seen, which is mounted at a distance from the shielding plates 2 by means of heating conductor suspensions 7.
- shielding modules 1 A disadvantage of shielding modules 1 according to the prior art is that a specially designed support structure, such as the support ring 17 in the present example, must be provided to support the shielding modules 1.
- the support structure must be specially adapted for different dimensions or shapes of high-temperature furnaces, since the support structure follows a contour of the furnace shell in order to be evenly spaced from it.
- FIGS. 2a to 2c show a shielding module 1 of the invention according to a first embodiment.
- the shielding module 1 is shown in a perspective view in FIG. 2a.
- the viewing direction points to the side facing a process space during use, that is to say to the shielding plates 2.
- the shielding module 1 comprises a plurality of shielding plates 2 arranged parallel to one another, which are connected to one another by bolts 13. The appropriate distance means are
- the shielding module 1 further comprises a base body 3, on which the package of shielding plates 2 is mounted.
- the base body 3 is designed in this embodiment as a box and consists of a base plate 31 (not visible in this view), which in the
- the basic body 3 here is an open box with four in this case
- Sidewalls 5 can be folded or flanged from the base plate 31 and / or placed thereon. For example, two of the side walls 5 can also be folded and two more can be attached.
- Gas passages 19 may be present on the base plate 31.
- Fastening points 4 in the form of bores 18 are provided on the side walls 5.
- attachment points 4 can be designed in the form of slots.
- Base bodies 3 can be connected to one another via the fastening points 4, for example via rivets or screws.
- Fastened connecting webs 41 by means of which a base body 3 can be connected to base bodies 3 of the same or at least similar design.
- the connecting webs 41 can be designed as simple sheet metal strips with two legs at an angle a to each other. The later angular position of base bodies 3 relative to one another is determined by the angle a.
- the connecting webs 41 are particularly suitable for connecting shielding modules 1 along a circumferential direction of one of a plurality of shielding modules 1 Heating insert.
- the shielding modules 1 can therefore be designed independently of the angular position to be set later. So you can
- shielding modules 1 of the same type can advantageously be used for different shapes and diameters of shields.
- the fastening points 4 in the form of bores 18 directly on side walls 5 of the base body 3 are particularly suitable for connecting shielding modules 1 along a longitudinal direction of a heating insert formed by a plurality of shielding modules 1. Here the connection is made in one level.
- the shielding module 1 also has heating conductor suspensions 7, to which a heating conductor 8 can be fastened.
- Heater conductor suspensions 7 can comprise sleeves, bolts or comparable fastening means which are attached to the base plate of the
- the heating conductor suspensions 7 are thus formed integrally with the base body 3.
- Figure 2b shows a plan view of the shielding module 1 with a view of the
- Connection provided side walls 5 can be brought to the plant.
- FIG. 2c shows the shielding module 1 in a stepped section, so that a bolt 13 and a gas passage 19 can be seen entirely.
- the angle a can be seen at which the connecting webs 41 run to the base plate of the base body 3.
- the heating conductor suspension 7 comprises one
- the heating conductor suspension bolt 71 is inserted into the guide sleeve 74.
- a pipe can also be used instead of a bolt.
- the heat conductor suspension bolt 71 is supported by the guide sleeve 74 a greater length than only the thickness of the base plate 31, which ensures a rigid mounting of the heating conductor suspension 7 on the base plate.
- Notches 21, 22 can also be seen in the package of shielding plates 2 on those sides of the shielding module 1, which one for connection to shielding modules 1 of the same type along a later circumferential direction
- Shielding modules 1 formed shield are provided. In the present example, this is the side of the shielding module 1 with the connecting webs 41 and the opposite side.
- the notches 21, 22 are designed to be correspondingly opposite, so that when two shielding modules 1 are connected, the notches 21, 22 engage in one another and thus overlap shielding plates 2.
- a shielding module 1 preferably has notches on two opposite sides, while the two remaining sides are free of notches.
- the sides with notches are provided for an angled connection of shielding modules 1, as occurs along a circumferential direction of a shield.
- the sides without notches are particularly suitable for a flat connection of shielding modules 1, as occurs along a longitudinal direction of a shield.
- FIGS 3a to 3c show the shielding module 1 after the same
- the shielding module 1 is shown in a perspective view in FIG. 3a. One looks at the rear of the shielding module 1, that is to say on the (cold) side facing away from a process space with regard to a later installation position. One can see the base plate 31 of the base body 3 and the side walls 5 which normally project therefrom. The heating conductor suspensions 7 and bolts 13, on which the shielding plates 2 are arranged and fastened, can also be seen.
- FIG. 3 b shows a top view of the shielding module 1 with a view of the base plate 31.
- FIG. 3c shows the shielding module 1 in a side view.
- FIGS. 4a to 4d show details of shielding modules 1.
- FIG. 4a two shielding modules 1 are shown in the cutout, which are arranged parallel to one another in a butt joint. It is advantageous if the shielding plates 2 are provided with notches 21, 22, as shown here, so that the shielding plates 2 at least partially overlap when two shielding modules 1 collide. This prevents direct radiation passage, as would be the case with a purely blunt impact.
- the shielding modules 1 lie in one plane. Notches 21, 22 are particularly advantageous for angled connections of shielding modules 1, as shown below.
- FIG. 4b shows an arrangement of two shielding modules 1, in which the shielding modules 1 are tilted towards one another. This arrangement occurs, for example, when shielding modules 1 are connected to one another
- FIG. 4c shows a configuration similar to FIG. 4b, but with the tilting of the shielding modules 1 relative to one another.
- a sealing cord (not shown) or the like can be inserted into the gusset resulting from the tilting of the shielding modules 1 between the side walls 5 of the adjacent shielding modules 1.
- FIG. 4d shows a detail of the structural design of the fastening of the shielding plates 2 on the base plate 31 of the base body 3.
- the shielding plates 2 are mounted via bolts 13 and spaced apart from one another by means of spacing means 14.
- the bolt 13 is secured to the base plate 31 in a suitable manner, for example via a counter.
- FIG. 5 shows a heating conductor suspension 7 according to an embodiment in detail.
- the heating conductor suspension 7 is an assembly of several components.
- the heating conductor suspension 7 comprises one
- Heating conductor suspension bolt 71 Heating conductor suspension bolt 71, a connecting rail 72 and one
- Heater holder 73 into which a heating conductor 8 can be inserted.
- the heating conductor suspension bolt 71 is fastened to the base body 3 via an integral guide sleeve 74.
- the heating conductor suspension bolts 71 protrude through the shielding plates 2 through corresponding recesses.
- a connecting rail 72 is formed between the heating conductor suspension bolts 71, to which the heating holders 73 can be attached.
- the connecting rail 72 is substantially normal to one
- the mounting of the heating conductor 8 via the heating holder 73 allows the heating conductor 8 to move due to thermal expansions.
- a heating conductor suspension 7 can in principle also be made simpler, but the construction shown here particularly advantageously supports a modular construction of heating inserts by joining similar types together
- the heating conductor suspension 7, as preferred and shown here, is designed as an integral part of a shielding module 1, a later installation of the heating conductor 8 is particularly simple.
- the provision of a connecting rail 72 allows the heater holders 73 to be freely positioned along the connecting rail 72, whereas, without a connecting rail 72, the position of the heater holders 73 is predetermined by the position of the heating conductor suspension bolts 71. This additional degree of freedom in the positioning of the heater holder 73 is particularly helpful for setting homogeneous heating conditions in a high-temperature furnace.
- FIG. 6 shows an arrangement of two shielding modules 1 which are connected to one another along an circumferential direction U at an angle a.
- the view corresponds to an end view of one of several of the same type
- Shielding modules 1 formed heating insert or a shield.
- shielding modules 1 can be used for different sizes and / or cross-sectional contours of heating inserts. Variants of
- Heating inserts particularly economical to represent are particularly economical to represent.
- the notches 21, 22 can be seen on the package of shielding plates 2 in such a way that part of the shielding plates 2 of a shielding module 1 into the gap formed by the notch in the package of shielding plates 2 of the adjacent one
- Shield module 1 protrudes.
- a shielding module 1 has notches 21, 22 on two side edges. The notches on one are preferred
- Shielding module designed so that when connecting shielding modules 1 along said side edges, the notch 21 of the one shielding module can engage in opposite notching 22 of the next shielding module 1, as shown in the present illustration.
- the notch 21, 22 can preferably be dimensioned such that, in a cold state, the shielding plates 2 do not touch when one is reached
- FIG. 7 shows a detail of an arrangement of shielding modules 1 in an assembly to form a heating insert 16. To make the details easier to see, a shielding module 1 was not shown compared to a real arrangement.
- heating insert 16 If heating conductors 8 are also attached to the insulating insert, this arrangement is referred to as heating insert 16.
- Shielding modules 1 are connected to one another via fastening points 4. It can be seen that shielding modules 1 both along a longitudinal direction L of the
- Heating insert 16 are connected to map its longitudinal extent, as well as connected along a circumferential direction U to set a desired diameter of the heating insert 16.
- the shielding modules 1 are connected along the circumferential direction U via connecting webs 41 described at the beginning.
- the shielding modules 1 are designed and positioned in relation to one another in such a way that the Notches described at the beginning intermesh in the circumferential direction U. This can prevent heat loss due to radiation during operation.
- the shielding modules 1 are connected to one another along the longitudinal direction L along those sides which have no notches.
- the shielding plates 2 are advantageously inserted one into the other along these joints, in order to establish a radiation-tight connection here as well.
- Shielding plates 2 protrude beyond the side walls 5.
- 16 assembled shielding modules 1 can be used for the assembly of the heating insert.
- the time-consuming assembly of individual shielding plates 2 at the place of use of the heating insert 16 is omitted. Repairs are also made considerably easier: defective shielding modules 1 can easily be replaced.
- the modularity also exists in the depth / longitudinal direction, i.e. e.g. a shielding module 1 can be exchanged at the front without having to take out the entire package of shielding modules 1 in the entire longitudinal direction.
- the shielding modules 1 are accessible on their cold side, that is to say on the side facing away from a process space 9.
- FIG. 8 shows a heating insert 16 in assembly in a perspective view.
- shielding modules 1 are along a longitudinal direction L and along a circumferential direction U des
- Heating insert 16 connected to each other.
- twelve shielding modules 1 are connected to form a ring with a cross section of a regular 12-corner.
- Four of the rings are connected along the longitudinal direction L to the total length of the heating insert 16.
- the heating insert 16 can be supported by four supports 10 (two of which are not visible).
- the supports 10 are here as roller bearings executed and thereby allow unhindered thermal expansion of the
- the supports 10 can be placed on rails on the inside of a furnace jacket of a high-temperature furnace (not shown here).
- Figure 9 shows the heating insert 16 of Figure 8 shows a front view.
- Shielding modules 1 delimit a process space 9.
