Description
15 20 25 30 35 452 001 Genom inslaget av hård karbid anordnad i den eldfasta matrisen i in- dividuella, i huvudsak jämnt fördelade stycken erhålles hög skär- resistens hos materialet. e ~ .Uppfinningen innefattar även ett sådant eldfast materials användning som konstruktionsmaterial f värdeförvarande enheter, såsom bankvalv, värdeskäp, bankserviceboxar och liknande enheter. 15 20 25 30 35 452 001 Due to the element of hard carbide arranged in the refractory matrix in individual, substantially evenly distributed pieces, high cutting resistance of the material is obtained. The invention also encompasses the use of such a refractory material as a construction material for valuable storage units, such as bank vaults, safes, bank service boxes and similar units.
Såsom tidigare antytts är den eldfasta matrisens uppbyggnad av s.k. grogg och bindemedel i och för sig konventionell till sin - karaktär, Groggen kan på traditionellt sätt utgöras av gryn eller korn av eldfasta material, såsom aluminiumoxid, bauxit, kaolin, a- åluminiumsilikat, kromit, zirkon, zirkoniumoxid, olivin, o.d. Ett speciellt föredraget material är a-korund, s.k. tabular aluminium- oxid. Som bindemedel kan med fördel användas kalciumaluminatcement, fosforsyrareller fosfat, silikatcement eller knlloidal kiselsyra el- ler blandningar av ett eller flera av dessa.As previously indicated, the structure of the refractory matrix of so-called grog and binders per se conventional in nature - The grog can traditionally consist of groats or grains of refractory materials, such as alumina, bauxite, kaolin, α-aluminum silicate, chromite, zirconium, zirconia, olivine, etc. An especially preferred material is α-corundum, so-called tabular alumina. Calcium aluminate cement, phosphoric acid or phosphate, silicate cement or colloidal silicic acid or mixtures of one or more of these can be used as binders.
Den i det eldfasta materialet enligt uppfinningen ingående värmeresistenta fiberarmeringen kan utgöras av stålfibrer, eller kolfibrer. Fiberarmeringen ingår i materialet i en mängd av lämp- ligen upp till ca 10 viktprocent och den utgöres företrädesvis av fibrer med en längd av upp till ca 10 cm, ex.vis från ca 2 till ca 5 cm, och en grovlek av ca 0,1 till ca 0,5 mm, ex.vis ca 0,2-0,3 mm. Såsom tidigare nämnts har denna fiberarmering till funktion att . förläna det eldfasta materialet tillfredsställande draghållfasthet så att det kan motstå åverkan genom ex.vis slag, sprängning eller fall från hög höjd. Materialet i fiberarmeringen skall uppvisa er- forderlig värmeresistens, vilket betyder att det bör tåla en tempe- ratur av flera hundra grader Celsius. På grund av den eldfasta matri- sens låga värmeledningsförmåga behöver fiberarmeringen för uppnående av värmeresistens ej tåla en väsentligt högre temperatur.The heat-resistant fiber reinforcement included in the refractory material according to the invention can consist of steel fibers, or carbon fibers. The fiber reinforcement is included in the material in an amount of suitably up to about 10% by weight and it preferably consists of fibers with a length of up to about 10 cm, eg from about 2 to about 5 cm, and a thickness of about 0, 1 to about 0.5 mm, eg about 0.2-0.3 mm. As previously mentioned, this fiber reinforcement has the function of. impart satisfactory tensile strength to the refractory material so that it can withstand impact by, for example, blows, explosions or falls from high altitudes. The material in the fiber reinforcement must have the required heat resistance, which means that it should withstand a temperature of several hundred degrees Celsius. Due to the low thermal conductivity of the refractory matrix, the fiber reinforcement does not have to withstand a significantly higher temperature in order to achieve heat resistance.
Den i det eldfasta materialet fördelade hårda karbiden kan utgöras av vilken som helst icke reaktiv karbid, såsom kiselkarbid, borkarbid, zirkoniumkarbid, hafniumkarbid, tantalkarbíd, kromkarbid, volframkarbid, vanadinkarbid eller mobbdenkarbid, Samtliga dessa karbíder är mycket högsmâltande och mycket hårda. Tänkbar är även en blandad karbid, såsom volfram-titankarbid, känd under namnet Kennametall, vilken även användes som hårdmetall i skärverktyg.The hard carbide distributed in the refractory material may be any non-reactive carbide, such as silicon carbide, boron carbide, zirconium carbide, hafnium carbide, tantalum carbide, chromium carbide, tungsten carbide, vanadium carbide or mobden carbide. All of these high carbides are very high carbides. A mixed carbide, such as tungsten-titanium carbide, known as Kennametall, which is also used as cemented carbide in cutting tools, is also conceivable.
Speciellt föredragna är emellertid kiselkarbid och borkarbid, i synnerhet den förra.Particularly preferred, however, are silicon carbide and boron carbide, especially the former.
LO 15 20 35 3 452 0o1l Såsom tidigare nämnts föreligger karbiden i form av individ- uella stycken, i huvudsak jämnt fördelade i den eldfasta matrisen.LO 15 20 35 3 452 0o1l As previously mentioned, the carbide is in the form of individual pieces, substantially evenly distributed in the refractory matrix.
Dessa karbidstycken har lämpligen en genomsnittlig tvärdimension av minst ca 5 mm, och tvärdimensionen ligger lämpligen inom intervallet ca 5-20 mm och speciellt ca 10-15 mm. Mängden i materialet ingående karbid är icke särskilt kritisk men den bör vara tillräckligt stor för att ge erforderlig inbrottssäkerhet mot ex.vis skärning. Dock bör karbidmaterialet ingå i det eldfasta materialet i en mängd som .är volymmässigt mindre än materialet som helhet. En lämplig mängd är upp till ca 20 viktprocent och är företrädesvis ej mindre än ca 5 viktprocent. d Ett tänkbart praktiskt exempel på framställning av en värde- förvarande enhet, ex.vis ett Värdeskåp, av ett eldfast material en- ligt föreliggande uppfinning kommer nu att beskrivas. Detta exempel får emellertid icke betraktas såsom inskränkande.These carbide pieces suitably have an average transverse dimension of at least about 5 mm, and the transverse dimension is suitably in the range of about 5-20 mm and especially about 10-15 mm. The amount of carbide contained in the material is not particularly critical, but it should be large enough to provide the required burglary protection against, for example, cutting. However, the carbide material should be included in the refractory material in an amount that is smaller in volume than the material as a whole. A suitable amount is up to about 20% by weight and is preferably not less than about 5% by weight. A possible practical example of the manufacture of a safe-keeping unit, eg a safe, of a refractory material according to the present invention will now be described. However, this example should not be construed as restrictive.
En lämplig gjutmassa för framställning av ett eldfast mate- rial försättes med en för gjutning lämplig mängd vatten, ex.vis 5-8 viktprocent. Gjutmassan kan ex.vis som eldfast matris bestå av ca 70 viktprocent u-korund som grogg och ca 30 viktprocent kalciumalu- mínatcement som bindemedel, jämte fiberarmering och lämpliga karbid- stycken jämnt fördelade i matrisen. Som gjutform användes en metall- låda motsvarande skäpets utseende, varvid själva skåpet framställes för sig, eventuellt även locket för sig och dörren för sig. Skåpets båda delar placeras på ett vibratorbord påverkat av högfrekvensvib- ratorer. Den fuktade gjutmassan ínföres sedan kontinuerligt på lämp- ligt ställe i skåpets delar, så att luften förtränges från skåpets inre utrymmen och luftfickor undvikes. När massan helt fyller upp skåpdelarnas inre utföres vibrering ytterligare under några minuter för fullständigt avlägsnande av luften och för uppnående av maximal densitet hos gjutmassan.A suitable casting compound for the production of a refractory material is added with a suitable amount of water for casting, eg 5-8% by weight. The casting compound can, for example, as a refractory matrix consist of about 70% by weight of u-corundum as grog and about 30% by weight of calcium aluminate cement as binder, together with fiber reinforcement and suitable carbide pieces evenly distributed in the matrix. As a mold, a metal box corresponding to the appearance of the cabinet was used, whereby the cabinet itself is manufactured separately, possibly also the lid separately and the door separately. Both parts of the cabinet are placed on a vibrator table affected by high-frequency vibrators. The moistened molding compound is then continuously introduced in a suitable place in the parts of the cabinet, so that the air is displaced from the interior spaces of the cabinet and air pockets are avoided. When the mass completely fills the interior of the cabinet parts, further vibration is carried out for a few minutes to completely remove the air and to achieve maximum density of the casting mass.
Skâpdelarna kan sedan torkas vid förhöjd temperatur,ex.vis vid 110°C i 24 timmar, varvid det eldfasta materialet hårdnar till erfor- derlig hållfasthet.The cabinet parts can then be dried at an elevated temperature, eg at 110 ° C for 24 hours, whereby the refractory material hardens to the required strength.
Efter det eldfasta materialets hårdnande kan sedan gjutformen d.v.s. metallmanteln avlägsnas, men ur estetisk synpunkt och för ex.vis målningsändamål kan metallmanteln bibehållas i samband med skäpets användning. _ Uppfínningen kommer i det följande att beskrivas närmare i anslutning till icke inskränkande konkreta exempel. 10 20 25 452 001 EXEMPEL 1 Gjutmassa med fysikokemisk bindning.After the refractory material has hardened, the mold, i.e. the metal jacket is removed, but from an aesthetic point of view and for eg painting purposes, the metal jacket can be maintained in connection with the use of the cabinet. The invention will be described in more detail below in connection with non-limiting concrete examples. 10 20 25 452 001 EXAMPLE 1 Casting compound with physicochemical bonding.
En gjutmassa av LCC-typen ("low cement content") bereddes ge~ nom torrblandning av följande beståndsdelar: 5-0 mmd Tabular alumíniumoxid 55 viktdelar (högsíntrad Al203) "_ " < 1,41 mm 17 " " " < 0,32 mm 10 " _Ka1cínerad aluminiumoxid < 0,062 mm 15 " Secar 7Q (kalcíumaluminat- 3 " cement) Kolloidal kiselsyra (Ludox HS40) 11 " I den genom mekanisk blandning av ovanstående beståndsdelar bildade gjutmassan inblandas sedan 11 viktdelar kiselkarbidstyck- en med en tvärdimension liggande inom intervallet ca S-10 mm samt 5,5 viktdelar stålfibrer med en längd av ca S0 mm och en grovlek av ca 0,2 mm. Dessa båda senare beståndsdelar fördelades jämnt i den beredda gjutmassan.d Den erhållna torrblandningen tillsättes sedan en för gjutning lämplig mängd vatten, vanligen ca 5-8 viktprocent, och användes för framställning av ett eldfast värdeskåp, varvid som gjutform användes en låda av stålplåt motsvarande värdeskåpets utseende.An LCC (low cement content) type casting compound was prepared by dry blending the following ingredients: 5-0 mmd Tabular alumina 55 parts by weight (high sintered Al 2 O 3) "_" <1.41 mm 17 "" "<0.32 mm 10 "Calcined alumina <0.062 mm 15" Secar 7Q (calcium aluminate 3 "cement) Colloidal silicic acid (Ludox HS40) 11" In the casting mass formed by mechanical mixing of the above constituents, 11 parts by weight of the silicon carbide piece are then mixed with an interval dimension approx. S-10 mm and 5.5 parts by weight of steel fibers with a length of approx. SO mm and a thickness of approx. 0.2 mm. These two latter constituents are evenly distributed in the prepared casting mass. The resulting dry mixture is then added to an amount suitable for casting. water, usually about 5-8% by weight, and is used for the manufacture of a refractory safe, using as a mold a box of sheet steel corresponding to the appearance of the safe.
Gjutmassan tillföres gjutformen på tidigare angivet sätt och skåp- delarna torkas vid ca 110°C under en tidrymd av ett dygn, och det eldfasta materialet hårdnar därvid och uppnår hög hållfashhet.The casting compound is added to the mold in the manner previously indicated and the cabinet parts are dried at about 110 ° C for a period of one day, and the refractory material thereby hardens and achieves high strength.
Värdeskåpets inbrottssäkerhet beträffande åverkan genom slag, borrning, skärning, sprängning, mejsling visar att höggradig in- brottssäkerhet uppnås jämte erforderligt brandskydd.The safe's burglary safety regarding damage through blows, drilling, cutting, blasting, chiselling shows that high-grade burglary safety is achieved together with the required fire protection.
Gjutmassa med konventionell bindning.Casting compound with conventional bonding.
.På samma sätt som i Exempel 1 bereddes en gjutmassa innehållande följande beståndsdelar: 5 . 452 001 _ Tahular alumíniumoxid 5-0 mm 45 viktdelar “" " < 1,041 m 11 " " " < 0,32 mm 10 " " ~ Kalcinerad aluminiumoxid < 0,062 mm 10 " CA-25-cement (Alcoa) I 18 " Kiseikarbiastycken s-1o 'mm 10 " Stâlfibrer med en längd av 30 mm och en 5 0 10 15 20 25 tjocklek av 0,2 mm Ett med denna gjutmassa framställt eldfast värdeskåp uppvi- sar samma höggradiga inbrottssäkerhet och brandskyddsegenskaper som värdeskåpet enligt Exempel 1.In the same manner as in Example 1, a casting compound containing the following ingredients was prepared:. 452 001 _ Tahular alumina 5-0 mm 45 parts by weight "" "<1,041 m 11" "" <0.32 mm 10 "" ~ Calcined alumina <0.062 mm 10 "CA-25 cement (Alcoa) I 18" Kiseikarbia pieces s -1o 'mm 10 "Steel fibers with a length of 30 mm and a thickness of 0.2 mm A refractory safe made with this casting compound exhibits the same high degree of burglary safety and fire protection properties as the safe according to Example 1.
EXEMPEL 3 Exempel 1 upprepas men med användning av kolfibrer i stället för stålfibrer, varvid samma högvärdiga egenskaper hos värdeskå- pet uppnås. 1 EXBMPEL 4 Exempel 2 upprepas men med användning av borkarbid i stället för kiselkarbíd, varvid ett värdeskåp med likvärdig inbrottssäker- het och likvärdigt brandskydd erhålles jämfört med egenskaperna för värdeskåpet enligt exempel 2.EXAMPLE 3 Example 1 is repeated but using carbon fibers instead of steel fibers, whereby the same high-quality properties of the safe are achieved. EXAMPLE 4 Example 2 is repeated but using boron carbide instead of silicon carbide, whereby a safe with equivalent burglary security and equivalent fire protection is obtained compared to the properties of the safe according to Example 2.
Det bör observeras att uppfinningen icke är inskränkt till an- vändning av det material som redovisas i ovanstående exempel. Så- lunda kan varje typ av groggmaterial med framgång användas och bin- demedlets karaktär är icke kritiskt. Vidare kan alla typer av skär- resistenta karbider användas i det eldfasta materialet enlígtuppfin- ningen, liksom även alternativa fibrer uppvisande erforderlig värme- resistens.It should be noted that the invention is not limited to the use of the material reported in the above examples. Thus, any type of grog material can be used successfully and the nature of the binder is not critical. Furthermore, all types of cut-resistant carbides can be used in the refractory material according to the invention, as well as alternative fibers having the required heat resistance.
