Definitions
- the invention is particularly concerned with practical and effective means of uniting and securing nonor weak structural insulations, such as bodies of refractory ber, and of high thermal tolerances with structural or supporting members such as steel or other appropriate metal plates or sheets, etc., to produce composite sections of integrated insulation and supporting or carrying structure, providing complete units suitable by themselves for use as walls, ceilings, or panel components for furnaces and the like foregoing high temperature chambers.
- Conventional high temperature installations such as furnaces, soaking pits, thermal stress relieving units, annealing furnaces, etc., are constructed with walls and/ or tops of refractory brick or block, such as insulating iire brick, normally braced or even supported with metal structures, and of compositions which typically range in densities of from about 25 pounds per cubic foot for maximum exposure temperatures of approximately 1,600'o F. up to about 65 pounds per cubic foot for a maximum exposure temperature of approximately 3,00()9 F.
- refractory brick or block such as insulating iire brick, normally braced or even supported with metal structures
- brick-type constructions aside from high initial construction cost and high weight, are by nature quite rigid and, therefore, prone to cracking and breakage, or spalling, etc., due to thermal expansion, present extensive joint exposure, and are costly to repair, among other signicant disadvantages.
- This invention comprises a high temperature insulating construction system and means therefor enabling more economical assembly of furnaces and the like high temperature chambers with wall and/ or top sections of panels of a more adaptable and versatile application and improved thermal insulating efciency over prior conventional brick-type systems.
- this invention comprises high temperature insulation construction system for walls, ceilings, panels, or the like sections, comprising an insulating material suitable for direct exposure to the "ice given conditions of heat, superimposed upon a supporting or bracing structural member of lesser thermal resistance and insulating efficiency, and in particular means for effectively uniting and securing the insulation to the supporting or bracing structure consisting of unique pin-like units which are easy to install with many types of common high temperature insulations, securely hold the insulating components and resist the temperature conditions of direct exposure to the source of heat.
- the pinlike units of this invention are secured by any one of several various means to the supporting structure and impale or pass completely through the body of insulating material or materials wherebyat least the exposed end and securing means thereon are composed of a refractory material which will endure the temperature environment.

- This invention essentially comprises a uniting and securing means to join a body of high temperature resistant insulation of little or no structural integrity to a supporting structure member, which consists of pin-like members of ceramic material, enabling the integration of a complete unit assembly of insulation and structural supporting member, which unit itself, or multiples thereof, can effectively serve as a furnace, or the like high temperature chamber, wall or top.
- the pin-like members of ceramic material, or the ceramic section of composite pins enables the positioning and effective fixing of the insulating material, Whether of low density, soft and flexible brous felts or blankets or of rigid semi-structural bodies, to the structural support member such as metal sheet, by permittnig the pin-like members to extend completely through the insulation and project out from the surface exposed to the high temperature conditions without any detrimental effects wherein the complete transverse of the body of insulation by the pin-like member provides for positive securing and xing of the insulation regardless of its consistency or density to the structural member and greatly facilitates assembling the composite unit and the fabrication of furnace and like high temperature chamber structures.
- FIGS. la and 1b illustrate a furnace construction system comprising an integrated unit of insulation and supporting structure joined and secured by means of a composite pin-like member of the preferred means and construction of the invention.
- the structural supporting member comprises a sheet of steel 10, or other appropriate metal, with the body of thermal insulation 11 superimposed thereon and each of said components is effectively united and secured together by means of pins 12 of a composite of a metal section 13, and a ceramic section 14.
- the metal section 13 of the pin 12 is secured to the structural support member and is adjacent to the exterior or cool face of the unit, and the ceramic section 14 extends through and beyond the insulation surface in the direction of the interior or hot face and is provided with a positive stop therebeyond and thus of necessity is exposed to maximum temperature conditions.
- the metal section 13 of composite pin 12 may be secured to the structural support member 10 by any appropriate means, such as by welds 15. And in the preferred embodiment, metal section 13 is joined to the ceramic section 14 by means of a threaded joint 16. As illustrated, the metal section 13 comprises the male component of the threaded joint which is preferred in that it enables the use of ordinary fiat-head bolts, and additionally facilitates mounting of the insulation thereon by irnpalement. However, the ceramic section 14 can be constructed with external threads and function as the male component whereby the cooperating metal female section, by surrounding the more fragile ceramic material, provides a stronger junction.
- the terminal end of the ceramic section opposite to the metal section 13 secured to structural support 10 is preferably formed in a point 17.
- a pair of two or more lugs such as illustrated lugs 18 and 18', positioned thereon at a point just beyond the designed thickness of the body of thermal insulation 11 mounted on the pins, which cooperate with ceramic Washer 19, provided with a center hole 20 and extending therefrom a pair of slots 21 and 21', each sized and positioned to cooperate with ceramic section 14 of pin 12 and lugs 18 and 18 thereon, whereby the washer may be slipped over the end of the ceramic section 14, past lugs 18 and 18', and then turned approximately 90, forming a bayonet coupling to provide a shoulder means forming a positive stop to retain the insulation 11 securely fixed in position. Details of the bayonet coupling
- the preferred furnace construction of this invention may -be conveniently assembled simply by welding standard bolts 13 to a common metal supporting plate member 10, threading thereon ceramic pin sections 14, and impaling insulating material 11, such as a plurality of fibrous blankets 22, 23, 24, and 25, as shown in FIG. la, upon the ends of the composite pin 12. Washers 19 are then positioned over the end of the pin just past lugs 18 and 18 and turned approximately 90, whereupon a unit suitable for furnace construction embodying both the structural support and insulating means is provided and the hot face surface of the unit comprising the exposed insulation and pin like members with securing components will withstand the high temperature environ- 4 ment of the furnace or the like high temperature charnber.
- FIGS. 3 and 4 illustrate variations of this invention comprising the use of ceramic pin-like members formed in the general configuration of common bolts.
- the body of insulation 11 is secured to structural 4.member 10, by providing member 10 with plurality of holes 26 to receive ceramic bolt 27 having a large head 28, to provide shoulder means for positively retaining the insulation.
- Bolt 27 is preferably constructed with a large diameter shank 29, approximately the length of the depth of insulation installed therewith, forming shoulder 30 of a diameter greater than hole 26 in structural support member 10, thereby functioning as a stop and fixing the positioning of the bolt.
- Terminal end of ceramic bolt 27 is provided with threads 31 on which nut 32 is applied to positively hold and fix ceramic bolt 27.
- nut 32 Since nut 32 is positioned on the cold face of the unit it can be composed of metal or the like low temperature resistant metal or material. With this arrangement a low density insulating material Which is highly compressible or resilient can be fixed into position and positively held without undue compression thereof, and in turn reduction in its insulating efiiciency.
- FIG. 4 illustrates a similar bolt-type shaft member comprising ceramic bolt 33 of generally conventional construction passing through a hole 26 in structural support 10, and having a head 34 with diameter greater than hole 26 functioning as the stop.
- the opposite terminal end of bolt 33 is provided with threads 35, la ceramic washer 36, and a ceramic nut 37 to hold washer 36 in place.
- the insulation 11 and structural support member 10, aptly provided with holes 26, are assembled juXta-position and the bolts pass through the insulating body 11 simply by force if the insulation is of sufliciently low density or through drilled holes if necessary in alignment with the holes 26 of structural support member, and washers where desired and nuts applied to the threaded ceramic bolts 27 or 33.
- threaded stud 38 iS Welded to structural support plate 10 and 'a ceramic shaft 39 threaded thereon with the stud forming the male member and shaft 39 the female member of the threaded connection.
- the terminal end of ceramic shaft 39 opposite threaded stud 38 can be provided with a pair of generally opposing lugs 40 and 40 to cooperate with a slotted washer 41 providing a bayonet-type coupling to form a shoulder stop to positively fix and secure the body of insulation 11, comprising for example a rigid material 42 which has been drilled forming holes 43 to permit it to be slipped over ceramic shaft 39 which joins and secures it to structural support member 10 to provide the furnace construction unit.
- the pin should be proportioned so that the ceramic section extends from the hot face or exposed surface Iback into the insulation to a point where the temperature is reduced sufhciently that the metal portion of the pin is not adversely affected by the heat.
- a high temperature resistant metal such as stainless steel
- a maximum safe temperature may be where the temperature does not exceed about 1,500 F., While for common steel it might be as little as 500 F. in order to insure prolonged effective operation of the furnace structure or similar high temperature chamber.
- furnaces or other high temperature chambers can be assembled from units comprising a metal plate with conventional bolts welded thereon which are tted with the ceramic portion forming the composite pin, having impaled thereon a conventional insulation of the desired thickness and secured with a washer which is applied simply by inserting it over the pin and applying an approximate turn.
- the metal plate may be drilled and ceramic bolts passed through the holes and the insulation, and fixed into place with either metal or ceramic nuts, depending on the direction of the bolt.
- the insulation may be drilled to accommodate the pins or bolts.
- Insulating materials for use in the construction system of this invention may comprise any conventional or commercial composition which will meet the given temperature requirements including common refractories, magnesia products, hydrated calcium silicates, but preferably fibrous insulations such as those described in pages 96 to 100 of Product Engineering, Aug. 3, 1964 or pages 91 to 95 of Product Engineering, Feb. 14, 1966, and composed predominately of alumina and silica alone, or modied as known in the art.
- Ceramic compositions for the ceramic section of the pins may comprise any high thermal shock resistant refractory having good strength at elevated temperatures such as high alumina compositions or mullite, bonded fused aluminum oxide, spinels, synthetic sapphire, magnesia, zircon or zirconia, silicon carbide, etc.
- said body of insulating material being secured to the structural supporting member by means of a plurality of spaced-apart pins of ceramic composition passing through the body of insulating material with one end secured to the structural supporting member and the opposite end extending through and exposed on the surface of the body of insulating material and having thereon shoulder means for holding the body of insulating material in position over the structural supporting member.
- Fastening means for securing an insulating body to a structural supporting member comprising an elongated composite pin having a metal section yancl a section of ceramic materials, said metal section being adapted to be secured to the structural supporting member and the section of ceramic material being adapted to extend through and beyond the insulating body and having on its terminal end means providing a shoulder to retain the insulating body and on its opposite end, adjacent to the metal section, having means to join with the metal section to form a continuous unit.
