Abstract
Kar for metallsmelter.Vessel for metal melter.
Description
Foreliggende oppfinnelse angår kar for metallsmelter hvor de karvegger som er innrettet til å holde på metallsmelten er oppbygget av separate deler av stivt, keramisk material, hvilke deler langs innbyrdes tilgrensende kanter oppviser fuger med i det minste to fugeflater som danner en vinkel med hverandre, slik som L- eller Z-fuger, idet de samvirkende fugeflater ligger mot hverandre via mellomlegg av keramisk tetningsmaterial. The present invention relates to vessels for melting metal, where the vessel walls which are designed to hold the molten metal are made up of separate parts of rigid, ceramic material, which parts have joints along mutually adjacent edges with at least two joint surfaces that form an angle with each other, as as L- or Z-joints, as the interacting joint surfaces lie against each other via an interlayer of ceramic sealing material.
Kar av ovenfor angitte type finnes i forskjellige utførelser. Blant slike kan nevnes digler og renner fremstilt av grafitt eller keramiske masser, utformet i ett stykke, samt metalliske karmantler foret med pressede masser eller med varmebe-standige, for eksempel keramiske, blokker eller tegl. Ved kon-vensjonell fremstilling av slike kar kreves kompliserte hjelpemidler, slik som formkonstruksjoner ved pressing eller støpning eller avansert verkstedutrustning ved fremstilling av metalliske karmantler. For at karene skal kunne tilvirkes til lave priser kreves derfor at et temmelig lite utvalg av slike kar tilvirkes i relativt store serier. En annen ulempe med slike konvensjonelle kar er at det foreligger fare for sprekkdannelse under tørkingen, brenningen eller oppvarmingen til driftstemperatur, hvilket medfører vraking under tilvirk-ningen, henholdsvis risiko for ødeleggelse på bruksstedene, særlig i forbindelse med igangsetting av driften. Vessels of the above type are available in different designs. Among these can be mentioned crucibles and gutters made of graphite or ceramic masses, designed in one piece, as well as metallic casings lined with pressed masses or with heat-resistant, for example ceramic, blocks or bricks. In the conventional manufacture of such vessels, complicated aids are required, such as form constructions by pressing or casting or advanced workshop equipment in the manufacture of metallic vessel mantles. In order for the vessels to be manufactured at low prices, it is therefore required that a rather small selection of such vessels be manufactured in relatively large series. Another disadvantage of such conventional vessels is that there is a risk of cracking during drying, burning or heating to operating temperature, which leads to breakage during manufacture, or risk of destruction at the points of use, particularly in connection with the start of operation.
Formålet med den foreliggende oppfinnelse er å komme frem til en ny, fordelaktig karkonstruksjon, der det i det minste i vesentlig grad unngås de ovenfor nevnte ulemper. The purpose of the present invention is to arrive at a new, advantageous vessel construction, in which the above-mentioned disadvantages are at least largely avoided.
For dette formål foreslås det i henhold til oppfinnelsen et kar for metallsmelter, hvilket kar kjennetegnes ved at delene utgjøres av plater hvis samvirkende fugeflater holdes trykket mot hverandre ved hjelp av skruer som er skrudd inn i platene og rager gjennom fugeflåtene og mellomleggene. For this purpose, according to the invention, a vessel for metal melting is proposed, which vessel is characterized by the fact that the parts are made up of plates whose cooperating joint surfaces are kept pressed against each other by means of screws which are screwed into the plates and project through the joint rafts and spacers.
Kar utformet i henhold til oppfinnelsen har i praksis vist seg overraskende pålitelige, og krever for oppbygningen bare enkelt utstyr. De kan med samme fremstillingsutstyr på en økonomisk gunstig måte produseres ett og ett eller i små serier i nær sagt hvilket som helst ønsket dimensjon og form, slik at avvikelser fra optimal utformning av hensyn til anvendelsesstedet i det vesentlige helt kan unngås. Karet i henhold til oppfinnelsen er først og fremst beregnet for an-vendelse i samband med støping av ikke-jernmetaller, slik som støpelegeringer på sink- eller aluminiumbasis. På det åpne marked finnes keramiske plater som er lette å bearbeide, idet de kan sages, freses og bores på omtrent samme måte som tre og tåler temperaturer på 700 - 800°C. Fremstilling av keramiske plater, som tåler enda høyere temperaturer og kan frem-stilles til konkurransedyktige priser, ligger imidlertid innen mulighetenes ramme. Platene kan med særlig fordel settes sammen slik at de ikke fuktes, impregneres eller angripes av slike metallsmelter de skal utnyttes i samband med. Risikoen for sprekkdannelse i et kar i henhold til oppfinnelsen er ved normal håndtering meget liten, ettersom de plater som kommer i kontakt med metallsmelter ikke skal brennes etter sammenset-ningen, og ettersom de labyrintaktige fugene i henhold til oppfinnelsen, samtidig med at de er lekkasjesikre, tillater mindre termisk betingede bevegelser. Vessels designed according to the invention have proven to be surprisingly reliable in practice, and only require simple equipment for construction. They can be produced with the same production equipment in an economically advantageous manner one by one or in small series in almost any desired dimension and shape, so that deviations from optimal design due to the place of use can essentially be completely avoided. The vessel according to the invention is primarily intended for use in connection with the casting of non-ferrous metals, such as casting alloys on a zinc or aluminum basis. On the open market there are ceramic plates that are easy to process, as they can be sawn, milled and drilled in much the same way as wood and can withstand temperatures of 700 - 800°C. However, the production of ceramic plates, which can withstand even higher temperatures and can be produced at competitive prices, is within the scope of the possibilities. The plates can be put together with particular advantage so that they are not wetted, impregnated or attacked by such metal melts with which they are to be used. The risk of cracking in a vessel according to the invention is very small during normal handling, as the plates that come into contact with molten metal must not be burned after assembly, and as the labyrinth-like joints according to the invention, at the same time, are leak-proof , allows less thermally conditioned movements.
Et kar som sett fra lekkasjesynspunkt er særlig pålitelig og samtidig enkelt å fremstille oppnås når karets vegger består av dobbelte, nær inntil hverandre beliggende plater, hvorved kantpartiet av en plate rager forbi den tilhørende annen plates kantparti til dannelse av de nevnte fugeflater. A vessel that is particularly reliable from the point of view of leakage and at the same time easy to manufacture is achieved when the walls of the vessel consist of double, closely spaced plates, whereby the edge part of one plate protrudes past the edge part of the associated other plate to form the aforementioned joint surfaces.
Det keramiske tetningsmaterial som benyttes som mellomlegg i fugene kan være pastaformet, men mellomlegg av keramisk filtmaterial, eventuelt i kombinasjon med pastaformet tet-ningsmasse har hittil vist seg mest pålitelig. The ceramic sealing material used as an interlayer in the joints can be paste-shaped, but an interlayer of ceramic felt material, possibly in combination with a paste-shaped sealing compound, has so far proven to be the most reliable.
For pressing av karets samvirkende fugeflater mot hverandre kan det med særlig fordel utnyttes skrueforbindelser, idet skruene griper direkte inn i det keramiske platematerialet. Imidlertid kan det tenkes andre måter å oppnå sammenpressing av fugeflåtene mot hverandre. For pressing the tub's interacting joint surfaces against each other, screw connections can be used with particular advantage, as the screws engage directly in the ceramic plate material. However, other ways can be thought of to achieve compression of the joint rafts against each other.
Sett fra et varmeøkonomisk og arbeidsmiljømessig synspunkt, og også med hensyn til brukstiden for karet, er det fordelaktig at karveggene omgis av isoleringssjikt samt en mantel som omgir disse. Såvel isoleringssjiktene som mantelen kan derved bestå, henholdsvis være oppbygget av, plater av keramisk material, hvorved det material som danner isoleringssjiktet med fordel kan være porøst, mens mantelsjiktet helst bør være slik at det er i stand til å holde metallsmelten på plass en viss tid i tilfelle brudd i en av karveggene. Seen from a heat economy and working environment point of view, and also with regard to the useful life of the vessel, it is advantageous for the vessel walls to be surrounded by an insulation layer and a mantle that surrounds these. Both the insulating layers and the mantle can thereby consist of, or be made up of, plates of ceramic material, whereby the material that forms the insulating layer can advantageously be porous, while the mantle layer should ideally be such that it is able to hold the metal melt in place for a certain time in the event of a rupture in one of the vessel walls.
Isoleringssjiktene kan langs de kanter der de henger sammen oppvise vinklede eller labyrintaktige fugeflater på hovedsakelig samme måte som de karvegger dannet av keramiske plater som kommer i kontakt med metallsmelten, slik at det i størst mulig grad unngås gassirkulasjon i isoleringssjiktene. Likeså kan isoleringssjiktene for dette formål med fordel grense til hverandre via material som tetter fugene mellom sjiktene. Along the edges where they join together, the insulation layers can exhibit angled or labyrinth-like joint surfaces in essentially the same way as the vessel walls formed by ceramic plates that come into contact with the molten metal, so that gas circulation in the insulation layers is avoided to the greatest extent possible. Likewise, for this purpose, the insulation layers can advantageously border each other via material that seals the joints between the layers.
Oppfinnelsen skal i det følgende beskrives ved hjelp av skjematisk viste utførelsesformer, under henvisning til de vedlagte tegninger. In what follows, the invention will be described using schematically shown embodiments, with reference to the attached drawings.
På de forskjellige figurer er innbyrdes like eller tilsvarende detaljer gitt samme henvisningstall. Fig. 1 viser i vertikalsnitt et kar i henhold til oppfinnelsen. Fig. 2 og 3 viser i perspektiv vertikalsnitt av et parti av henholdsvis en annen og tredje utførelsesform av karet i henhold til oppfinnelsen. In the different figures, identical or corresponding details are given the same reference number. Fig. 1 shows a vertical section of a vessel according to the invention. Fig. 2 and 3 show in perspective a vertical section of a part of a second and third embodiment of the vessel according to the invention, respectively.
Karet vist i fig. 1 har en bunn 10, sidevegger 11 og et lokk 12, som via tetninger 13 ligger mot overkantene av veggene 11. En metallsmelte som befinner seg i karet er betegnet med 14. For å sikre god tetning er det i de undre partier av veggene 11 utfrest eller på annen måte utformet spor, slik at det oppnås L-formede fuger, der veggene 11 og bunnen 10 er innbyrdes forbundet. I fugene er innlagt remser 15, 16 av keramisk filtmaterial, hvorved fugeflåtene holdes trykket mot hverandre ved hjelp av skruer 17. De vertikale hjørner, der karets vegger 11 møtes, er passende utformet på tilsvarende måte som de viste horisontale hjørner i overgangen mellom The vessel shown in fig. 1 has a base 10, side walls 11 and a lid 12, which via seals 13 lies against the upper edges of the walls 11. A metal melt that is in the vessel is denoted by 14. To ensure a good seal, it is in the lower parts of the walls 11 milled or otherwise designed grooves, so that L-shaped joints are obtained, where the walls 11 and the bottom 10 are mutually connected. Strips 15, 16 of ceramic felt material are laid in the joints, whereby the joint rafts are kept pressed against each other by means of screws 17. The vertical corners, where the vessel walls 11 meet, are suitably designed in a similar way to the horizontal corners shown in the transition between
vegger og bunn, slik at det dannes labyrintaktige hjørnefuger. walls and bottom, so that labyrinth-like corner joints are formed.
Karet vist i fig. 2 skiller seg fra karet i henhold til fig. 1 hovedsakelig ved at bunnen og veggene dannes av dobbelte keramiske plater 19, 20, henholdsvis 21, 22. Ved fugene rager derved de ytre kantpartier av platene 20, 22 forbi de tilhør-ende kantpartier av de indre platene 19, 21, slik at det dannes i det vesentlige Z-formede fuger, med fugeflåtene holdt trykket mot hverandre ved hjelp av skruer 17 via mellomlegg 15, 16, 23 av for eksempel keramisk filtmaterial. Mellomleggene 16 og 23 rager forbi fugeområdene, og har på den viste måte fortrinnsvis samme utstrekning som de ytre platene 20, 22. Ytterligere skruer kan, slik som vist ved 24, være anordnet for fastklemming av de ytre og indre platene 19 og 20, henholdsvis 21 og 22 mot hverandre via mellomleggene 16, 23. The vessel shown in fig. 2 differs from the vessel according to fig. 1 mainly in that the bottom and walls are formed by double ceramic plates 19, 20, respectively 21, 22. At the joints, the outer edge parts of the plates 20, 22 thereby protrude past the corresponding edge parts of the inner plates 19, 21, so that essentially Z-shaped joints are formed, with the joint rafts kept pressed against each other by means of screws 17 via spacers 15, 16, 23 of, for example, ceramic felt material. The spacers 16 and 23 project past the joint areas, and in the manner shown preferably have the same extent as the outer plates 20, 22. Additional screws can, as shown at 24, be arranged for clamping the outer and inner plates 19 and 20, respectively 21 and 22 against each other via spacers 16, 23.
Karet vist i fig. 3 er en videreutvikling av karet i henhold til fig. 2. Det skiller seg fra karet i henhold til fig. 2 hovedsakelig ved at det er utstyrt med en isoleringskonstruk-sjon, bestående av indre og ytre porøse plater 25, 26 av varmebestandig, for eksempel keramisk material. Som vist, er platene 25, 26 ved hjørnene sammenføyd på hovedsakelig samme måte som de ovenfor beskrevne plater 19-22. Isoleringskon-struksjonen omgis av en mantelkonstruksjon dannet av keramiske plater 27 og holdt sammen ved hjelp av skruer 28. The vessel shown in fig. 3 is a further development of the vessel according to fig. 2. It differs from the vessel according to fig. 2 mainly in that it is equipped with an insulating construction, consisting of inner and outer porous plates 25, 26 of heat-resistant, for example ceramic material. As shown, the plates 25, 26 are joined at the corners in substantially the same manner as the plates 19-22 described above. The insulation construction is surrounded by a casing construction formed of ceramic plates 27 and held together by means of screws 28.
For kar som skal tåle temperaturer opp til ca. 800°C kan platene 10, 11, 12, 19 - 22 og 27 med fordel bestå av det keramiske platematerial som tilvirkes av Johns-Manville, Colorado, U.S.A., under benevnelsen Marinite-XL, mens de iso-lerende platene 25, 26 og tetningene 30 for eksempel kan bestå av materialer markedsført av samme firma, under betegnelsen Thermo-800 henholdsvis Cerafelt CB-1000. Mellomleggene 15, 16, 23 kan med fordel bestå av det keramiske filtmaterial som tilvirkes av Carborundum Co., N.Y., U.S.A., under betegnelsen Fiberfrax Ceramic Fiber Paper, Grade 970 J, hvorved mellom-leggenes tykkelse passende kan være opptil ca. 3 mm. For vessels that must withstand temperatures up to approx. 800°C, the plates 10, 11, 12, 19 - 22 and 27 can advantageously consist of the ceramic plate material manufactured by Johns-Manville, Colorado, U.S.A., under the name Marinite-XL, while the insulating plates 25, 26 and the seals 30, for example, can consist of materials marketed by the same company, under the name Thermo-800 or Cerafelt CB-1000 respectively. The intermediate layers 15, 16, 23 can advantageously consist of the ceramic felt material manufactured by Carborundum Co., N.Y., U.S.A., under the designation Fiberfrax Ceramic Fiber Paper, Grade 970 J, whereby the thickness of the intermediate layers can suitably be up to approx. 3 mm.
