The present invention relates to a heat insulating member and its installation method. In particular, the present invention relates to a heat insulating member for surface insulation, a method for insulating the surface and a method for attaching the surface material, and more specifically, a high temperature heat insulating material in the furnace to insulate the furnace surface insulating member and the furnace surface. It is about how to install.

Problems when insulating the inner surfaces of walls (walls, ceilings, inner door surfaces, other inner surfaces to be insulated) are known. Historically, various types of refractory bricks have been used to insulate the interior of hot furnaces. However, it is not only time-consuming but also cumbersome to replace these fire bricks with new ones.

In view of the need for higher temperatures and better efficiencies due to defects in refractory bricks, insulating fibrous materials such as ceramic fiber materials are used to provide insulation or at least to provide a high temperature side of the insulation. Was done.

Therefore, in the present invention, as a ceramic fiber material, a ceramic material in the form of a ceramic fiber blanket generally manufactured by a method similar to a conventional papermaking method is generally used. Fibers constituting the blanket are used as a blanket or It is oriented in a plane parallel to the longitudinal direction during sheet forming.

If a cross section of such a blanket or sheet is to be cut into a matt or batt and applied to the inner surface of the furnace, the ceramic fibers are placed in a plane parallel to the surface on which the mat or bat is attached.

In the application of the blanket shape to this shaped surface, most of the fibers of the ceramic material tend to be displaced, but most of these ceramic fibers are directed in a straight direction. When the fiber is in a plane arranged parallel to the furnace wall, there is a general tendency for cracking due to heat shrinkage.

Moreover, when the ceramic fibers are used in the form of blankets, high temperature causes devitrification and layer separation and cracking.

Several attempts have been made to overcome the drawbacks of using ceramic fibers in blanket form by dividing the ceramic fibers into sheet-shaped strips and placing them horizontally in the fiber placement direction.

The strip divides the fiber sheet by the width of the fiber blanket, i.e. the width representing the linear distance between the hot and cold sides. When the cutting strip occurs at the edges, as many as the number of fibers corresponding to the required thickness of the fibers in the longitudinal direction at the surface-to-face contact of the ceramic fibers.

Naturally, the number of strips needed to make up the required thickness of the fiber can be determined from the thickness of the fiber on which the strip occurs.

In general, the application of strips appearing in the inner wall of the fiber when the fiber extends transversely to the inner wall of the furnace and when the fiber surface extends transversely to the inner wall can fundamentally reduce problems such as devitrification, layer separation, shrinkage and cracking. .

In addition, since the ceramic fibers are elastically compressed (or compressible with limited elastic modulus), the strips may be overlapped to avoid gaps between strips due to shrinkage during use.

Whether a blanket is used in the form of a blanket or in the form of a strip, several methods for bonding the inner wall of the furnace are required. In order to achieve this purpose, various methods have been tried. For example, in the case where the insulation is used in the form of a blanket, the pin or the stud is welded to the inner wall of the furnace in advance. It is to secure the position by the coupling means.

However, this work requires the pins or studs to be fixed in advance at specific points on the inner wall of the furnace, and the pins or studs cannot be easily changed. Furthermore, because the fins or studs extend through the insulation, they will be exposed to the high temperatures in the furnace and conduct heat directly to the furnace walls. This not only creates undesirable hot spots on the furnace walls but also wastes them.

Where insulation is used as strips (slab boards), the insulation is fixed with wires or the like on brackets pre-welded to the inner wall of the furnace. This also has the drawback that, like the above-described method, the blanket must be welded in advance to a specific position of the furnace inner wall and it is impossible to change this position. Moreover, this method is very difficult and cumbersome to handle strips.

To address this drawback, attempts have been made to fix the insulation to the furnace wall by forming a modale by installing the insulation in a rigid ceramic material block or support sheet or panel. Such modules can be handled separately and can be installed on solid walls, sheets or panels on the furnace walls.

This method offers several advantages, but the efficient aspect of fixing the insulation is still a problem. In other words, fixing the back plate (insulation fixing part) with a rigid ceramic block and fixing the insulation with wires or rods is not only cumbersome but expensive, and is not particularly efficient because the back plate is not strong. .

Therefore, the following method is to use the back plate as a heat resistant material, which method has been relatively successful in many conventional (patent) applications. However, this method also has a problem. That is, when fuel is burned in the furnace, sulfur (sulphite gas) is generated, and when a little moisture is added thereto, sulfuric acid becomes corroded and the inner wall of the furnace and the heat insulating material are corroded. No useful attachment means or ceramic cement can prevent corrosion and prolong the service life. Thus, the use of useful attachment means or ceramic cement will quickly insulate the insulation from the backplane and interior walls.

If iron is present here, it reacts with sulfuric acid to become iron sulfate, which leads to extremely corrosive insulation. Ironically, when the ceramic fiber insulation mat is attached to the furnace wall by heat-resistant attachment means or cement, a temperature gradient is formed only in the remaining portion of the insulation mat except the low temperature side portion. In other words, there is almost no temperature gradient for sulfuric acid in the cold side of the insulation mat. Therefore, sulfuric acid penetrates only in the most fragile parts of the insulation system, so that the metals, which are corroded by sulfuric acid, are supplied to the furnace and the insulation of the insulation to produce the iron oxides that corrode the ceramic fibers in the outer parts of the furnace or in the most fragile parts of the insulation back plate. will be.

Therefore, the life of the insulation is limited to the period of time until the heat-resistant attachment means or cement eventually wear out, and in some cases, the insulation mat is attached to the outside of the back plate or the furnace, and the ceramic fiber adhered to the heat-resistant attachment means or cement is corroded. It is decided to break by action. Therefore, ceramic fibers tend to break the attachment means or adjacent parts of the cement layer after a period of use. Thus, two types of breakdowns in this critical area ultimately break the ground insulation system.

Accordingly, it is an object of the present invention to provide a heat insulator that can reduce or fully overcome the drawbacks of conventionally known methods of insulating the surface of an object.

Due to the heating effect in the furnace, the heated air rises upward, causing excessive pressure on the top of the furnace. This overpressure consequently causes the flow of air to flow outward from the furnace inner wall.

Thus, the furnace insulation system allows air to enter the gap between the insulation and the outside of the furnace so that the air cooled in the air flow through the insulation at the top of the furnace travels down between the insulation and the shell of the furnace.

Applicant believes that the above air flow will meet the air between the insulation and the shell of the furnace, thus causing heat loss and causing corrosion of the contact area.

In the prior art, even if the heat insulator is firmly attached to the furnace wall, the temperature gradient of the furnace wall or furnace shell will be inclined gently. Therefore, the outer skin will cause a shape change such as the surface is blocked or concave. Thus, if the heat insulator is firmly attached to the furnace outer wall as in the prior art, a gap naturally occurs due to the shape change of the furnace shell.

Thus, in many applications for insulation, it is advantageous that the insulation is firmly attached to the furnace walls or the periphery despite the deformation of the furnace shell due to temperature changes.

Therefore, an object of the present invention is to firmly attach the heat insulator to the furnace wall or the shell.

The principles of the present invention can be used to firmly attach insulation to the backplane to insulate the furnace, and the invention is particularly used to insulate the inner walls of high temperature furnaces.

"High temperature" in the present invention means more than 1600 ° F (about 870 ° C), preferably from 1600 ° F (about 870 ° C) to 280 ° F (about 1540 ° C).

In addition, the wall of a furnace means all the walls which require heat insulation including the ceiling of a furnace and the opening of a furnace.

Ceramic fiber insulation is commercially available and known in the art. For example, ceramic fiber insulation is registered under the trade names "Kaowool" (Babcock and Wilcox), "Fiber-Frax" (Carborundum Co), "Lo-Con" (Carborundum Co.), "Cero-Felt" (Johns-Manville Crop.) It is made of “SAFFIL” (ICI), etc. The ceramic fiber insulation is usually used at 2300 ° F. (about 1260 ° C.) Also, when the fiber insulation is used as a strip, it is reprocessed to 2800 ° F. (about 1540 ° C.). A suitable grade of fiber insulation is that used at about 2800 ° F. (about 1540 ° C.), which is “SAFFIL” as the alumina fiber in the above examples.

According to one aspect of the present invention, there is provided an insulating member on an insulating surface, which is a) a low temperature surface disposed opposite to one surface and a high temperature surface and a deformable insulating mat facing the same, and b) the insulating member. Attaching means for attaching to the surface, the attaching means is an anchor means arranged on the mat is disposed between the hot surface and the cold surface in order to arrange the attachment means with respect to the mat, to attach the member to one surface It includes a connecting means connected to the anchor means attached to the surface, the connecting means when the pressure means is pressed to the attachment surface is a groove is formed inside the low temperature surface with respect to the attachment means to press the low temperature surface.

The heat insulating member of the present invention may have a sheet or strip shape. However, preferably, the heat insulating member of the present invention may be used side by side in the form of a module or a block corresponding thereto to form a heat insulating wall.

Thus, the heat insulating member of the present invention can be in the form of a square or rectangular module. The thickness of the module depends on the thermal insulation properties of the insulation and the conditions of the furnace in which the insulation is used.

The mat-shaped insulation can be used as any stacked insulation that provides the required insulation and can be at least partially deformed and preferably has a limited degree of elasticity and is elastically pressed to bond the mat to the furnace surface.

Therefore, as an example, the heat insulating material includes a fibrous heat insulating material such as mineral fiber material, a refractory fiber material or a ceramic fiber material. However, other suitable materials may be used as long as the supplied insulation can be at least partially deformed and at least a portion is elastically deformed so that the mat-shaped insulation can be elastically pressed to engage the surface to be insulated.

If the insulation is a fiber insulation, this insulation can be used in the form of a blanket for the particular use of the present invention, wherein the fibers are arranged in the fiber plane and when the insulation is attached to one surface these planes are arranged substantially parallel to the surface to be insulated.

This blanket shape, however, introduces several drawbacks, and in a preferred embodiment of the present invention, when insulating a high temperature furnace with a service temperature of 1600 ° F. (about 870 ° C.) or higher, the insulation is arranged to extend across the low temperature side of the heat insulating member. Materials comprising a plane are preferred and the fibers are randomly oriented in the fiber plane.

The attachment means can be displaced and most attachment means can be constructed from materials that are suitably elastically deformed or displaced.

In embodiments of the present invention, difficulties arise if the attachment means are not molded from an elastically deformable material that can withstand high temperatures without losing its elastic modulus or if the attachment means are not placed on the mat to be protected at temperatures at which they will lose elasticity.

Thus, in a preferred embodiment of the present invention, the attaching means can be elastically deformed by having an elastically deformable portion disposed in proximity to or disposed on the low temperature surface of the insulating mat or the insulating member during use. This enables the elastic deformation portion to be protected even in the elastic deformation portion in which the thickness of the mat-shaped insulation is overheated during use, so that the elastic deformation portion can maintain the pressurization during use.

In one example, the attachment means comprises an anchor means connected to a mat-shaped insulation and a yoke means extending from the connection means for attaching the surface to be insulated. In an embodiment of the invention, preferably the yoke means comprises an elastically deformable portion of the attachment means.

The anchor means can be connected to the mat-shaped heat insulating member of the present invention and can be attached to the surface to be insulated, which can be suitable means for attaching the heat insulating member to the heat insulating surface.

For example, the anchor means includes one or several elongated rods, bars or tubes disposed on the mat. In another embodiment of the present invention, the anchor means is in the form of a grid or enclosed rods arranged in a mat. In another example, the anchor means is arranged in an elongated but nonlinear mat-shaped insulation.

The anchor means itself is elastically deformed, while the original anchor means can be made of a rigid material so that the tension applied to the anchor means is evenly distributed throughout the anchor means, thereby affecting the comfort of the mat-shaped insulation.

In a preferred embodiment of the invention the anchor means comprises a plurality of anchor tubes which are arranged in the rear direction so as to extend through the mat in a plane extending parallel to the cold surface and thereby tension applied to the anchor means. Is evenly distributed throughout the mat.

Where the mat-shaped fiber insulation extends perpendicular to the cold surface, the anchor tube is preferably extended parallel to the hot surface. However, it provides the effect of the placement of anchor tubes in the mat in the plane of the fiber insulation.

In an embodiment of the present invention, a reinforcing material may be disposed in the mat to reinforce the mat in the vicinity of the anchor means to better distribute the pressing force applied to the anchor means during use of the mat.

The reinforcement material may comprise a weldment of the net structure or adhesive material.

The yoke means are shaped to be coupled to the anchor means and to be attached to the insulating surface.

According to one embodiment of the present invention, the yoke means includes an elastic deformable fixing part attached to a surface to be insulated with a connecting limb connected to or coupled with the anchor means so as to extend toward the low temperature surface. It is to elastically press the connection rim so that the mat of the anchor means and the heat insulating member is moved to the surface to be insulated.

In a preferred embodiment of the present invention, the elastically deformable fixing portion is supplied with a spring or similar member to provide a pressing action, for example, a helical spring or a leaf spring.

In another preferred embodiment, the elastically deformable fixing portion may be in the form of a fixing ring extending transversely to the connecting rim.

In the present embodiment of the present invention, the yoke means is provided with a pair of connecting rims which are all connected together by a fixed rim to provide a connecting rim having one end at a free end in the cross section of the channel shape of the yoke means. The free end of is to be connected or coupled to the anchor means.

Preferably, the attachment means is arranged in the mat so that the elastic deformation portion is recessed inwardly of the low temperature surface. Thus, the elastic deformation portion elastically presses the attachment means by the deformation toward the surface to be insulated from the mat and tilts the mat toward the heat insulation surface during use.

In one embodiment of the invention the attachment means comprise a fastening device used to secure the attachment means to the surface to be insulated.

The fixture is provided with a hole for receiving bolts, screws, welding studs, and the like, for securing to the surface to be insulated.

The fixing device may be integral with the material of the continuous extension or the yoke means. The securing device may also be in the form of a separate securing device which is secured to the yoke means of the attachment means.

The holding device includes a holding member in the form of a welding stud extending into the mat, wherein the welding stud has an available portion extending through the hole of the holding device. In this embodiment, the fixture includes an arc protector covering the fusible portion of the weld stud to attach the surface to be insulated by internal welding.

Furthermore, the attachment means may further comprise a pressing means for attaching the fixing device to the insulating surface to press the ground fixing device to the surface to be insulated. In one example, the pressing means is provided with a stud or bolt and a similar threaded nut adapted to be inserted into the holding means. Thus, the elastically deformable fixing part on the insulating surface side is insulated and the elastic pressing effect is exhibited.

Furthermore, embodiments of the present invention also include a method of providing a heat insulator on the furnace surface, which supplies a mat-shaped heat insulator to the low temperature side of the furnace and the high temperature side opposite it. Attachment means are provided at a portion away from the hot surface to press the cold surface of the mat towards the furnace surface.

The method includes a method of elastically pressing the mat to be matched to the furnace surface.

Preferred embodiments of the present invention include a method of maintaining a pressurizing action such that the mat is pressurized such that the mat-type insulating material is pressed in conformity with the road surface, even though the road surface is bent due to temperature changes.

This method is such that the elastically deformable attachment means connected to the mat is attached to the road surface to attach the mat to the road surface, and the attachment means is elastically pressed toward the road surface to maintain a pressure bond between the mat and the road surface.

Furthermore, the present invention provides an attachment means for attaching the mat-shaped insulation to the road surface, wherein the anchor means for mat placement and the yoke means extending from the anchor means toward the road surface and the mat are directed toward the road surface. Attachment means and the like are elastically deformed to be pressurized.

If the attachment means is rigid then the pressing action can take place by elastically compressing the mat. On the other hand, if the attachment means is provided with an elastic deformation, it is possible to provide a connection means to obtain a pressing action by the elastic deformation of the connection means, or by the elastic deformation or elastic compression of the connection means or by the elastic deformation of the mat.

The present invention provides an embodiment of a heat insulating member for insulating the furnace surface, which has a low temperature surface facing the furnace surface during use and a high temperature surface and a plurality of side surfaces facing the furnace surface, the member is made of fiber insulation And a means for attaching the modified mat and the mat to the furnace surface: a) The fiber insulation comprises a fiber plane arranged to extend transversely to the plane of the hot surface, wherein the fiber of the fiber material B) the attachment means comprises: i) a plurality of long anchor members disposed on the fiber plane where the hot and cold surfaces are spaced apart from each other, and ii) a fixed rim and a plurality of connecting rims extending therefrom. Each connecting rim includes a free end connected to one of the anchor members, and the fixed rim is described above. It forms a fixed area spaced inward from the side of the member and disposed adjacent to the cold surface for use in securing the member to the surface of the furnace.

In this aspect, in the preferred embodiment of the present invention, the fixing area is arranged in the center of the insulation module and the anchor means are arranged on the mat, and the connecting rim is attached to the fixing area of the heat insulating material to fix the mat disposed on the surface of the furnace during use. Is connected to the anchor member by means of an attachment force.

The connecting means usually extend at both ends of the fixed rim.

In a preferred embodiment of the invention, the attachment means comprises at least two anchor members arranged laterally spaced apart, the cross section of the yoke means being channel shaped.

In one embodiment of the present invention, the connecting rim may consist of a continuous extension of the fixed rim. The fixed rim may also have a connecting rim hinged at both ends thereof.

In one aspect of the present invention, a heat insulating material made of a mat may include a composite heat insulating material consisting of a plurality of heat insulating materials of various different shapes. In this respect, the combination of high and low temperature insulation materials can be used practically and in the most economical conditions in any particular environment and temperature conditions.

While the furnace of the present invention is efficient and suitable for high temperature insulation, the present invention may be equivalent to other types of thermal insulation in that it is necessary to firmly attach between the insulation and the surface to be insulated.

Therefore, any other type of thermal insulation method is included within the scope of the present invention. However, in the preferred embodiment of the present invention, although the conventional insulation system exhibits a major drawback, the present invention can be used in high temperature furnaces because it can provide various advantages.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

Referring to FIGS. 1 and 2, reference numeral 10.1 generally denotes a high temperature insulation module for insulating a high temperature furnace, in which the module 10.1 is placed on the furnace surface to be insulated with the deformable mat 12 of the insulation. Attachment means 14. 1 attaching the mat 12, which may be elastically deformed to elastically press the mat 12 in such a manner as to be mated with the road surface.

The mat 12 has a low temperature surface 16 facing the furnace wall or skin wall surface to be insulated during use and a high temperature surface 18 on the opposite side of the low temperature surface 16 facing the furnace wall.

The elastically deformable mat 12 is preferably formed of a ceramic fiber material in which the ceramic fiber material is randomly oriented in the fiber plane 20 and the fiber plane is the hot surface 18 at the low temperature surface 16. Are arranged side by side to extend vertically).

In a special arrangement of the fiber planes, the ceramic fiber strips are placed at the end or edge exposure of the fiber plane 20, where the deformation mat 12 must withstand delamination, in particular devitrification. It must be able to withstand the phenomenon and cracks.

Moreover, the inherent elasticity of the ceramic fibers makes it possible to effectively cover and hide the attachment means in the mat. The attachment means prevents the heat received from the furnace by the fibers.

The attachment means 14.1 comprise anchor means 22 and yoke means 24.1.

The anchor member 26, which is the anchor member, is preferably made of a tube of ceramic material extending from one side of the mat 12 to the opposite side, and is separated from the low temperature side 16 and the high temperature side 18, respectively.

In the embodiment of the present invention shown in the drawings the anchor tube 26 is spaced about 2 inches (about 50 mm) in the low temperature surface (16).

The anchor tube 26 is sufficiently separated to protect the hot surface 18 of the mat from heat from the furnace, and thus the yoke means 24.1 is also protected from overheating during use.

The yoke means 24.1 comprises an elastically deformable fixing part in the form of a connecting limb 28.1 and a fixed rim 30.1.

The connecting rim 28.1 is provided with a hook-shaped member 32 at its free end, and the hook-shaped member 32 is coupled to the anchor tube 26 to provide the yoke means 24.1 to the anchor means 22. Will be connected.

The fixed rim 30.1 extends transversely from the opposite end of the connecting rim 28.1 thereby providing an "L" shape.

The yoke means 24. 1 is made of a suitable material which is elastically deformed so that the attachment means 14. 1 are elastically deformed while having corrosion resistance.

In the preferred embodiment of the present invention, the yoke means 24.1 is preferably made of stainless steel so that it can be deformed and elastically deformed.

In a preferred embodiment of the invention, the yoke means 24.1 is made of a material having a high yield strength, such as A304 stainless steel. One such material is 18-8 stainless steel A304, which is corrosion resistant, suitably designed and positioned and can be elastically deformed during use in the required area.

In one example, the yoke means 24.1 is a rod of diameter 3/16 inch (about 9 mm), and the anchor tube is a ceramic tube having an outer diameter of 1/2 inch (about 12 mm) and an internal diameter of 1/4 inch (about 6 mm). It is 12 inches long (about 300 mm).

The thickness of the mat 12 between the hot side and the cold side is suitable for the furnace conditions in which the insulating module 10.1 is used. Typical examples are at least 3 inches (about 75 mm) and generally at 3 inches (about 75 mm). It can vary between 6 inches (about 150 mm).

It has an effective elastic compression effect of the mat 12 because it has sufficient ceramic fibers between the anchor tube and the low temperature surface 16 to adequately protect the anchor tube 26 from heat. Anchor tubes are generally spaced about 2 inches (about 50 mm) from the cold surface 16. The space, however, depends on the environment of the furnace in which the module 10.1 is designed, the type of material from which the mat 12 is made, the conductivity and properties of the yoke means 24.1 and the compression of the mat required.

The yoke means 24. 1 engages with the anchor tube 26 and extends towards the cold surface 16. The fixed rim 30.1 extends transversely to the connecting rim 28.1 and generally lies on the plane of the cold surface 16.

The fixed rim 30.1, however, contracts inwardly of the low temperature surface 16 which permits elastic pressing of the yoke means 24.1 to provide an elastic pressing action during use.

The extent to which the fixed rim 30.1 shrinks into the mat 12 behind the low temperature surface 16 depends also on the conditions of the furnace described above and also on the elasticity and shape of the yoke means 24.1. In the embodiment of FIG. 1, the fixed rim 30.1 is concave in size between 1/2 inch (about 12 mm) and 1 inch (about 25 mm) from the cold surface 16.

The attachment means 14. 1 include fastening means 34 for using the fixed rim 30.1 on the surface of the furnace shell 38 or the furnace wall 36, as shown in FIG. 2.

The fixing means 34 comprises a gripping flange at the opposite end of the bottom wall 40, a flange 42 at one end of the bottom wall 40, and a bottom wall 44 coupled to the fixed rim 30.1 ( 44) in the form of a fixing bracket. The gripping flange 44 is coupled with the fixing means 30.1 to be crimped by welding. Otherwise it is connected directly.

The bottom wall 40 is provided in a hole 46 for receiving a welding stud to securely secure the fixed rim 34 to the surface 36.

As shown in FIG. 2, the module 10.1 is supplied with a fixing portion 48 for fixing the fixing means 34 to the furnace surface 36. As shown in FIG.

The fixing portion 48 consists of a threaded shank 52 extending through the hole 46 and a weld stud 50 having a stud tip 54 of relatively small cross section at the end.

Pressing means consisting of a nut 56 is arranged on the threaded portion 52.

Furthermore, the fixing device 34 is provided with an arc protector 58 of ceramic material disposed thereon. The arc protector 58 is secured by an annular support washer (not shown), which has fingers extending radially inward to engage the groove of the stud tip 54.

In order to attach and use the module 10.1 on the surface 36 of the furnace, the insulation 10.1 has attachment means 14.1 located therein, fixing means 34 and fixing means 34 mounted on the fixed rim 30.1. The shank 52 and the nut 56 which are appropriately arranged are supplied. The module 10.1 also includes a removable guide sleeve 60 disposed on and coupled to the nut 56. The sleeve 60 is also used as a guide surface, a conductor and a torque device when welding.

An internal welding tool 62 is used to attach the module 10.1 to the surface 36 of the furnace. The welding tool 62 is electrically operated and is supplied with a cylinder for firmly coupling the sleeve 60.

In order to attach the module 10.1 to the surface, the module is placed on the opposite side of the surface and then the cylinder of the tool 62 is inserted into the guide sleeve 60.

In this position, the welding tool 62 enables the current to flow through the sleeve 60, the stud tip 54 and the threaded portion 52 into the shell 38. The stud tip 54 is arced due to the small cross-sectional area of the stud and starts to burn and the arc is protected by the arc protector 58.

The shank 52 does not move toward the surface 36 of the furnace because it is supported by the support flange described above.

As the welding continues, the intense heat of the arc burns the radial fingers of the support flange, causing the shank 52 to enter the molten metal by the arc. Welding is completed here with shank 52 integrally mounted to surface 36.

The nut 56 can be secured on the shank 52 simply by rotating the welding tool 62 around the barrel axis because it is engaged with the sleeve 60 which in turn engages with the barrel nut 56. The nut 56 may be secured on the shank 52 until the nut 56 is supported against the anchor 34 and moves the anchor 34 in contact with the furnace surface 36. During this movement, the nut 56 acts as a pressing means for the pressing means to elastically press the fixed rim 30.1 from the mat 12 toward the road surface 36. The unpressurized position of the fixed rim 30.1 is shown in dashed lines in FIG. 2 and the pressed position is shown in solid lines.

The yoke means 24. 1 tension the anchor tube 26 while the fixed rim 30.1 is elastically pressurized. Anchor tube 26 is made of an elongated tube is distributed in the longitudinal direction when the tension is applied. Therefore, the fiber insulation between the anchor tube 26 and the road surface is compressed and the mat 12 is firmly attached to the road surface 36.

Since the fixed rim 30.1 is elastically displaced during the period in which the thermal insulation module 10.1 can be used, the elastic compression of the mat 12 attached to the furnace surface 36 is maintained.

Since the fixed rim 30.1 is disposed in the vicinity of the low temperature surface 16 of the insulation module 10.1, the adjacent rim of the fixed rim 30.1 and the connecting rim 28.1 has the elastic deformation in use. It is maintained at a sufficiently low temperature due to the thermal insulation of the mat 12 during the maintenance.

When the mat 12 is firmly attached to the road surface 36 and elastically pressurized, there is an advantage of providing an air gap and an advantage of providing a contact area between the low temperature surface 16 and the road surface 36.

Since the yoke means 24.1 maintains the pressurizing effect, even if the road surface 36 is bent or warped due to temperature change, the low temperature surface 16 can maintain the elastic contact with the road surface 36. .

Therefore, if the air gap between the cold surface 16 and the road surface 36 is removed or reduced, it is possible to remove or reduce the air flow flowing down the gap along the road surface 36 in use. In addition, it is possible to increase the efficiency by reducing the heat loss.

Furthermore, as described above, corrosion can be prevented by limiting air flow along the interface between the low temperature surface 16 and the furnace surface 36.

The insulation module 10.1 provides the attachment means 14.1 and the fixing device 34 to the fixed rim 30.1, which greatly increases the inner area of the insulation. Corrosion must therefore occur because the means are used below the average conditions of the furnace. The remainder of the yoke means 24. 1 is arranged at suitable intervals on the low temperature side 16 to receive high temperatures such that sulfuric acid and sulfurous acid cannot be present because of no moisture present.

If there is a rapid component in the furnace shell and the yoke means 24. 1 and iron sulfate is formed and corrosion occurs in the low temperature region, the low temperature surface 16 of the mat 12 is corroded. However, such corrosion is not so harmful to the use of the insulation module 10.1. Where the ceramic fiber insulation is corroded, it provides a fiber that prevents corrosion, which can be compared to the use of adhesives or cement in the contacts in the prior art. In the thermal insulation module of the prior art, the fiber corrosion in the area is to cause the fibers to fall off the adhesive and eventually to break.

Compared with the prior art, the insulation module 10.1 at the contact portion of the low temperature surface 16, the corrosion affects the insulation characteristics of the insulation module 10.1 or the insulation module 10.1 attached to the furnace surface 36 It's not serious enough to separate it.

Such anchor tube 26 can be eliminated by being made of a non-corrosive material and the yoke means 24.1 being made of a corrosion resistant material. If desired, the yoke means 24.1 may be further coated with a corrosion resistant material.

The insulation module 10.1 has four sides that are light so as not to be disturbed by a coupling member such as a back plate or a block.

Therefore, the insulation module (10.1) can be elastically compressed with each other when attached to the surface, so that even if the center of the inner block due to the outer shell or heat changes, or a gap between the insulation module (10.1) they are very narrow and shallow, that is, fine You have the benefit of doing it.

Moreover, even when the insulation module 10.1 is used in the open-air ceiling, since the tension is evenly distributed in the anchor tube 26, the insulation module 10.1 may reduce the effect of falling down due to gravity or leaving the ceiling. It also reduces the gap between insulations.

1, it can be seen that the anchor tube 26 extends horizontally on the fiber plane 20 so that it can be effectively positioned on the mat 12.

The yoke means 24. 1 is also arranged parallel to the fiber plane 20. Therefore, the attaching means 14.1 is disposed about half of the fiber plane 20 of the insulation module 10.1 and the yoke means 24.1 is arranged thereon to secure the anchor tube 26 through the hook-shaped member 32. The half is inserted into the fiber and then placed in place by screwing onto the remaining portion of the remaining reaction anchor tube 26 of the fiber plane 20. The anchor tube 26 is accommodated in the hole formed in the fiber plane of the mat 12.

With reference to FIG. 3, there is shown another insulating module 10.3 according to the invention. However, this is also similar to the insulation module (10.1) and attached similarly.

The insulation module (10.1) is about half compared to the other and has a thin and long shape, and is used to connect the long and long spaces, and the single anchor tube (26) is fixed to the connecting rim (28.1) for the yoke means (24.1). Only one rim (30.1) is associated with each one.

Insulation module 10.3 shown in FIG. 3 has a more constant specification in a forward direction or a rectangular shape. And since the width is wider than the insulation module 10.1, the attachment means 14.3 is extended so that the tension applied by the insulation module 10.3 is distributed from the mat 12 to the elastic stress.

The insulation module (10.3) is 12 inches x 12 inches. However, in a preferred embodiment it may be 11 inches x 11 inches to provide effective elastic compression of the insulation module.

The attachment means 14.3 includes a pair of anchor tubes 26 spaced apart from each other axially. The anchor tube 26 extends transversely to the fiber surface to effectively and firmly adhere the mat 12 to the fiber surface 20.

Each anchor tube 26 is about 11 inches or 12 inches long and 1/2 inches in diameter, protrudes in the longitudinal direction of the cold surface 16 of the mat 12 and has a fiber cross-sectional area of approximately 6 square inches. The mat 12 itself is arranged in the longitudinal direction with a cross-sectional area of the low temperature surface 16 of 144 square inches. The Applicant has recognized that ceramic fiber is suitable for the mat material having the above dimensions, and also recognized that the projected area of the anchor tube 26 is about 10% of the projected area of the mat. It has also been found that the anchor tube 26 does not act to elongate the holes provided in the mat 12. In other words, the area between the anchor tube 26 and the mat 12 is sufficient as described above, and even when the insulation module 10.3 is attached to the road surface as the fixing device 34, the insulation module 10.3 is formed by the mat 12. It can be safely supported without relatively rocking relative to the cold surface 16.

By forming the anchor member in the form of a tube 26, the supporting area can be increased without increasing the weight. Therefore, the anchor tube 26 has an advantage that can effectively support the insulation module (10.3).

The yoke means 24.3 comprises a pair of connecting rims 28.3. Each connecting rim 28.3 is provided with a hook-shaped member 32 which hangs on one side of the anchor tube 26 at its free end.

Both ends of the connecting rim 28.6 are connected with the fixed rim 30.3. The stationary rim 30.3 includes a stationary device 34 disposed thereon.

The fixed rim 30.3 shrinks inwards about 1/2 inch inward of the cold surface 16, is disposed parallel to the cold surface 16, and is elastically bent to attach to the furnace shell or furnace wall surface, thereby anchoring the tube (26) is elastically pressed and the mat 12 is coupled to match the road surface.

Due to the arrangement of the anchor tube 26 and the yoke means 24.3, the fixing device 34 has a low temperature surface of the insulation module 10.3 at a central position spaced inward from the four sides of the insulation module 10.3. .

Therefore, when the insulation module 10.3 is attached to the furnace wall using the fixing device 34, the attachment force applied by the fixing device 34 to the wall is determined by the anchor tube 26 and the yoke means 24.3 through the mat 12. Distributed in. Therefore, the insulation module 10.3 is attached to the furnace wall to effectively insulate.

4 to 7, there is shown a thermal insulation module 10.4 used for high temperature insulation, such as thermal insulation module 10.3.

Therefore, similar parts are designated by similar numbers.

4 shows a thermal insulation module 10.4 attached to the furnace wall. A guide sleeve 60 is included in the fixing device 34, which guides the internal welding tool 62 to a position as shown in FIG.

The attachment means 14.4 of the insulation module 10.4 are shown in detail in FIGS. 5 and 6. Each part is similar to the signs of similar parts in FIG. However, the support flange 64 is shown at the point in FIG. The outer circumference of the support flange 64 has a periphery that works with the protector to hold the arc protector 58 in place. The support flange 64 has a finger extending radially inwardly to friction and engage the stud tip 54. If the finger melts during welding, the shank 52 at the portion of the stud tip 54 welded on the furnace surface 36 is loosened.

7 shows a thermal insulation module 10.4 attached to the road surface 36. Fixing device 34 is coupled to furnace surface 36 using nut 56 on shank 52. This causes elastic deformation to occur at the original position indicated by the solid line as indicated by the dotted line in FIG. When the fixed rim 30.4 is elastically pressurized as described above, it causes an elastic pressing tension on the anchor tube 26, so that the anchor tube 26 firmly couples the mat 12 on the road surface 36. .

The fibers of the mat 12 can be elastically compressed to some extent so that they adhere firmly even when irregularly deformed to the furnace surface during use.

8, there is shown an embodiment of another thermal insulation module 10.5 according to the invention. The insulation module 10.5 is identical to the insulation module 10.4 except for a pair of parallel anchor tubes 26 which are inclined at an acute angle to one of both sides of the mat 12.

Arranging the anchor tube 26 as described above is coupled side by side so that the surface and the surface of the insulation module is elastically compressed without interference between the anchor tube 26 of the two adjacent insulation module (10.5). This requires the use of a curved tube 26 because the insulation module is not straight.

9, there is shown a heat insulation module 10.6 which is another embodiment of the present invention.

The yoke means 24.6 in the insulation module 10.6 are two yoke members that are resistance welded to each other to form a hole 46.6 for receiving the stud tip 54 and the shank 52 of the fixing member 48. Is included.

Insulation module 10.6 is elastically tensioned by the yoke means 24.6 is distributed on the main plane of the mat 12 by the four connecting rims to thereby be mated to match the surface on which the mat 12 is to be mounted Sometimes it is elastically pressurized.

10 and 11, another embodiment 24.7 of the yoke means 24.1 shown in FIG. 1 is shown.

The yoke means 24.7 is formed to be bent in a long "L" shape with high yield strength to form the fixed rim 30.7 and the connecting rim 28.7.

The connecting rim 28.7 is hooked on the anchor tube 26 while the fixed rim 30.7 is provided with a hole 46.7 to provide a washer to distribute the load evenly. The load here is the force tightened by studs, bolts and screws to secure the fixed rim 30.7 to the shell or furnace wall.

12, there is shown a thermal insulation module 10.8 which is another embodiment of the invention.

The insulation module 10.8 is provided with three anchor tubes 26, three connection rims 28.8 and a single fixed rim 30.8 connected to the three connection rims 28.8, except that the insulation module 10.4 is provided. Similar to).

By increasing the number of anchor tubes 26 and connecting rims 28.8, the elastic tension applied to the mat 12 can be increased, so that the shape of the insulation module can be changed according to various requirements.

12 illustrates a mat 12 of the insulation module 10.8 having improved durability.

The method of improving the durability of the mat 12 is to be interposed by a welding method such as injecting a suitable synthetic resin into the region 75 between the low temperature surface 16 and the anchor tube 26.

The synthetic resin is provided to the reinforcement area 75 for suppressing the elongation of the hole supplied to the anchor tube 26 so that when the anchor tube 26 is elastically pressed toward the furnace wall surface, the anchor tube 26 effectively applies the insulation module. Is to compress.

Thus, the reinforcement region 75 is subjected to the compressive force of the anchor tube 26. And gelatinous silica of synthetic resin supplied to the reinforcement region 75 described above.

The compressive force of the anchor tube may be distributed by other means as the anchor tube extends backwards.

In the present invention, in order to facilitate handling of the insulation module, the insulation module may be wrapped with an elastic material, a paper strip, or a reddish. To open the mat 12 in the packaged state, the above-mentioned packaging material may be torn or loosened, and thus the fibers of the mat are elastically expanded.

13 and 14 show a heat insulation module 62.1 which is another embodiment of the present invention.

The insulation module 62.4 is generally similar to the insulation modules 10.3 and 10.4 shown in FIGS. 3 and 4. However, the difference is that the insulation module 62.1 is not elastically compressed or pressed against the furnace wall.

The insulation module 62.1 is provided with a mat 63.1 modified from a suitable insulation module and has a low temperature side 661, a high temperature side 65.1 and four sides 66.1.

The insulation module 62.1 includes attachment means for attaching the mat 63. 1 to the furnace surface to be insulated. This attachment means 67.1 includes a plurality of elongated anchor members 68.1 that are annular. The insulation module 62.1 is supplied with two anchor members 68.1 which are arranged opposite each other and are slightly spaced apart from the low temperature surface 661 and the high temperature surface 65.1. Therefore, in each anchor member 68.1, the insulation module of the mat 63.1 arranges the anchor member 68.1 between the mat and the low temperature surface. In addition, each anchor member (68.1) is sufficiently supplied with an insulation module between the anchor member and the high temperature surface (65.1) to protect the anchor member (68.1) from the heat received during use.

The attachment means 67.1 include yoke means 69.1.

The yoke means 69.1 are provided with a fixed rim 70.1 in parallel with the vicinity of the low temperature surface 661, and a pair of connecting rims 71.1 extending in parallel with each other at both ends of the fixed rim 70.1. It is provided.

The connecting rims 71.1 are configured by extending the fixed rims 70.1 and are integrated with each other.

Each free end of the connecting rim 71.1 is bent in a circular or hook shape so as to slide on the anchor means 68.1.

The fixed rim 70.1 forms a fixed area 77.1 at the center thereof, and a fixed area 72.1 is provided at an adjacent portion of the low temperature surface 661, and the fixed area 77.1 is provided on the side of the insulation module 62.1. It is arranged inward of (66.1). In fact, in FIG. 13, the fixing area 75.1 is disposed at the center of the side surface 66.1 of the insulation module 62.1.

Therefore, when the fixing area 77.1 is formed on the surface of the furnace with a suitable fixing device, the attachment force therein is distributed to the yoke means 69.1 through the anchor member 68.1 after passing through the effective area of the mat 63.1. Thus, the insulation module 63.1 can be effectively disposed on the furnace wall surface as a single fixed area 7.3.1.

By using a fixing device connected to the fixing area 77.1, the central portion of the mat 63.1 can be attached to the road surface.

As described above, the mat 631 protects the attaching means 67.1 and the fixing area 77.1 and the fixing device.

Thus, by arranging a single fixed area in the center of the insulation module, the adhesive force is advantageously distributed evenly in the insulation module of the mat 63.1.

As shown in Fig. 13, the present invention attaches the mat 63.1 to the furnace surface with the attachment means 67.1 to provide extensive protection against heat. In other words, it has the advantage of effectively protecting the fixed area (73.1) and the fixed rim (70.1). The protection area of the road surface can be changed as required by the fixed rim 70.1 by changing the low temperature surface 661 of the mat 63.1, i.e. by adjusting the size of the low temperature surface and the road surface.

The attachment means 67.1 are placed in a position where the heat of the furnace can be directly received during use, i.e. the stress acting on the attachment means 67.1 by placing the area of the hook-shaped member 72.1, which is the upper end, in the position as described above. This has the advantage of reducing this to a minimum. In the region where the stress applied to the attachment means 67.1 becomes greater, that is, in the joining region of the connecting rim 71.1 and the fixed rim 70.1, the space from the hot surface can keep the temperature at the lowest point in this region. . Thus, the maximum strength with respect to the attachment means 67.1 is generated at the lowest received temperature of the attachment means so that the elasticity is the lowest.

As shown in FIG. 13 and FIG. 14, the fixed area 77.1 is composed of a fixed plate 74.1 on which a fixed rim 70.1 is spot welded. The stationary plate 74.1 is provided with holes 76.1 for receiving bolts and studs for attachment to the furnace wall.

15 and 16, there is shown an embodiment of the attachment means 67.2 used for the insulation module 62.1 shown in FIG.

The attachment means 67.2 is similar to the attachment means 67.1 except for the fixed area 77.2.

The fixed area 77.2 is a channel-shaped bracket 74.2 in which the fixed rim 70.2 is fixed by spot welding. When viewed from above, the fixed rim 70.2 is shaped like a "V" and the holes 76.2 of the bracket 74.2 are provided on the line of the hook-shaped member 72.2 so that the fixed area can disperse the force attached to the furnace wall. .

Referring to FIGS. 17 and 18, there are shown attachment means 67.3 which are essentially similar to the attachment means 67.2 shown in FIGS. The attachment means 67.3 is provided with a fixed rim 70.3 having a semicircular shape instead of the fixed rim 70.2 having a V shape. The semi-circularly curved fixed rim ensures that the hole 76.3 provided in the fixed area 73.3 is provided on the line of the hook-shaped member 72.3.

19 and 20, another embodiment of the attachment means 67.5 is shown.

The attachment means 67.5 are provided with a pair of stationary rims 70.4 in the form of rods. The fixed rim 70.4 is provided with a connecting rim 71.4 having a "U" shape. Thus, the "U" shaped connecting rim is in the form of a hook-shaped member 72.4 at both ends.

The central part of the fixed rim 70.4 is bent to form a fixed area 73.4 for receiving the fixed device.

Referring to FIG. 21, another embodiment 67.5 of the attachment means is shown.

The attachment means 67.5 is essentially similar to the attachment means 67.1 shown in FIG. Thus, the attachment means 67.5 are provided with yoke means 67.5, which are provided with a fixed rim 70.5 and a connecting rim 71.5, which are fixed. It extends from the rim 70.5 and the fixed area 73.5.

At the contact portions of the connecting rims 71.5 at the ends of the fixed rims 70.5, the yoke means 69.5 made of stainless steel bars are flat to reduce the bending resistance. The connecting rim 71.5 is therefore already bent in the opposite direction to the direction facing each other in the plane of the plane.

The shape of the yoke means 66.5 is very suitable for the mat and can elastically compress the mat to the surface to be insulated. Thus, the typical yoke means 67.5 are arranged to shrink inwardly at the low temperature side of the mat. When the fixed area is on the road surface, the mat is elastically compressed by placing the fixed rim 70.5 in contact with the road surface to elastically bend. If no bending occurs at the connection of the connecting rim 71.5 and the fixed rim 70.5 while the fixed rim 70.5 is arranged, the hook-like member 72.5 is arranged in the opposite direction. This leads to an undesirable phenomenon in which the width of the mat is reduced.

Referring to FIG. 22, another embodiment 62.7 of the yoke means is shown. This yoke means 69.6 has the same purpose as the yoke means 69.5. In the yoke means 69.6 the connecting rim 71.6 is hinged to the fixed rim using an extra hook-shaped member 77.6.

Referring to Fig. 23, another embodiment 62.7 of the insulation module is shown. This insulation module 62.7 is provided with attachment and anchor means 67.6 and a fixing area 73.7 contained in the mat 63.7 and the yoke means 66.9. The fixed area 73.7 is contracted to the inside of the low temperature surface of the mat 63.7 to be attached to the road surface on which the mat is insulated and elastically pressed, and the adhesive force is used to elastically compress the insulation module of the mat 63.7 to the road surface. (63.7).

The mat 63.7 is composed of a first layer 78.7 and a second layer 79.7. The first layer 78.7 has a higher adiabatic temperature than the second layer 77.9. This composite mat 63.7 can reduce the cost of the insulation module depending on the furnace atmosphere.

When constructing the composite mat 63.7, the first layer 78.7 is preferably a layer formed from ceramic fiber material in the soft particle direction. The second layer 77.9 also has a blanket shape, preferably in the direction of the soft particles, similar to the first layer and the fiber plane generally parallel to the low temperature surface.

A blanket-shaped second layer is provided between the composite mat 63.7 and the furnace surface to provide elasticity between the anchor tube 68.7 and the low temperature surface. Moreover, due to the edge direction of the fibers of the first layer 78.7, the insulation module 62.7 does not lose its elastic effect with adjacent insulation modules during use.

The first layer 78.7 of the composite mat 63.7 is an 8 pound density SAUDER ^™ ceramic fiber while the second layer 79.7 is an 8 pound density rock wool blanket.

In the above-described configuration, where the thickness of the composite mat is 125 mm, the insulation module 62.7 is suitable for use in a furnace having a hot surface temperature of about 1420 ° F (771 ° C). The contact surface temperature between the first layer 78.7 and the second layer 77.9 is about 950 ° F. (510 ° C.), while the temperature on the cold side is about 178 ° F. (81 ° C.).

The composite mat of the present invention can be used as a lower level of the insulation module attached to the low temperature surface has the advantage of reducing the cost. In addition, since the temperature of the low temperature side can be lower than the temperature normally used, it is necessary for a special use.

24 to 26, another embodiment 62.8 of a thermal insulation module is shown.

The insulation module 62.8 is provided with a composite mat 63.8 and attachment means 66.8 arranged in the composite mat.

The composite mat 63.8 is provided with a first layer 78.8 and a second layer 79.8. Preferably, the first layer is a useful ceramic fiber of 6 pounds density with the trademark "SAFFIL" while the second layer 79.8 is a useful ceramic fiber with a density of 8 pounds with the trademark "SAUDER".

The thickness of the first layer is preferably 114 mm and the thickness of the second layer is preferably 152 mm. The insulation module 62.8 is suitable for providing a hot surface temperature of 2400 ° F. (1316 ° C.) on the furnace surface. In use, the temperature of the anchor tube (68.8) is 2000 ° F (1093 ° C), the contact surface of the first layer (78.8) and the second layer (79.8) is 1733 ° F (945 ° C) and the temperature of the low temperature side is 200 ° F (93 ° F). )

Since the service temperature of the anchor tube 68.8 is relatively very high, a high alumina ceramic material is used as with the attachment means 66.8.

The attachment means 67.8 are supplied with long bolts extending from the fixed rim 70.8 to the fixed area 73.8.

In a preferred embodiment, the fixed area 73.8 is arranged on the low temperature side such that the mat 63.8 will not be elastically compressed when the insulation module 62.8 is attached to the furnace surface. If it is to be elastically compressed, the fixed area 73.8 is contracted into the cold surface. Moreover, the fixing bracket is elastic so that the attachment means 66.8 are in the elastic zone furthest from the cold surface. Thus, as the temperature rises during use, the increase in elasticity is minimized.

Referring to FIG. 27, an embodiment 62.9 of a thermal insulation module is shown. The insulation module 62.9 is essentially similar to the insulation module 10.43 shown in FIG.

The insulation module 62.9 is supplied with two pairs of anchor tubes 68.9 and 80.9. The anchor tube 68.9 is connected to the yoke means 67.9, and the anchor tube 80.96 is connected to a similar yoke means 67.9.

Each yoke means 67.9 is provided with a fixed area 73.9 disposed at the center of the mat 63.9.

In the embodiment of FIG. 27, by providing a plurality of yoke means and a plurality of anchor tubes in the insulation module 62.9, it can be more firmly attached to the furnace surface, and the adhesion force will be evenly distributed throughout the mat 63.9. will be. This arrangement allows the mat 63.9 to be more firmly and securely attached and supported.

The insulation module described so far has the advantage of easy assembly and disassembly due to its simple structure. If all the elements of the insulation module are configured, the support means, the attachment means and the fibers contained in the mat are assembled. The insulation module can be attached to the mat in the fixed area of the attachment means.

An advantage of the above insulation module is that the position of the attachment means can be changed as necessary to evenly preserve the adhesion to the mat of the insulation module. Moreover, the attachment means may be simply attached to the road surface, or a coal compressive force may be applied to the road surface. Therefore, when the attachment means are arranged, the fixed area is on the low temperature side or protrudes from the low temperature side. If the attachment means is arranged to elastically compress the insulation module at the road surface, the fixing area should be arranged to contract inwardly from the low temperature surface and to elastically compress the insulation module to the furnace surface. The degree of compression is adjusted in accordance with the extent to which the stationary zone shrinks into the cold surface.

By using a pair of anchor members arranged at the rear and the attachment means of the "U" shape or the channel cross section, the attachment force can be evenly distributed on the mat, whether the insulation is effectively supported or elastically compressed to the furnace surface during use.

As described above, the yoke means of the shape provides an advantage that the anchor member is pulled toward the low temperature surface in an equilateral triangle shape on the low temperature surface. In addition, by arranging the batch attachment means in the center of the insulation, the insulation can be effectively attached by a single point of attachment protected from the furnace heat. The single point of attachment is sufficient to attach a common insulation member and the insulation can be constructed at low cost. Using such attachment means, the attachment force will be evenly distributed on the yoke means, the anchor means and the mat.
