Description
Denne oppfinnelse.angår ildfaste komponenter og mer bestemt angår den ildfaste innsatser for bruk i faste eller' forskyvbare plater i beholderutstyr som vanligvis benevnes sleidesperreventiler i metållsmelte- og støpeverk. This invention relates to refractory components and more specifically it relates to refractory inserts for use in fixed or displaceable plates in container equipment which are usually referred to as slide stop valves in metal smelting and foundries.
Kort fortalt er sleide.portvéntiler utløpreguleringsmeka-nismer. for .bruk på øse-/traktinnretninger og består i hovedsa-ken av to plater ,med åpninger i', den ene fast. og på. linje med Briefly, slide port valves are outlet control mechanisms. for use on ladle/funnel devices and mainly consists of two plates, with openings in them, one fixed. and on. line with
en åpning..i-, bunnen- av beholderen og den andre forskyvbart.montert under den- faste plate,' idet metallet tømmes- ut når de to åpninger er i flukt med.hverandre. Platene er fremstilt av et ildfast.materiale og hver ligger an mot andre ildfaste- dyser, an opening in the bottom of the container and the other displaceably mounted under the fixed plate, the metal being discharged when the two openings are flush with each other. The plates are made of a refractory material and each rests against other refractory nozzles,
en øvre dyse montert over den stasjonære plate og. en nédre dyse eller, samledyse, montert under' sleideplaten. an upper nozzle mounted above the stationary plate and. a lower nozzle or, collecting nozzle, mounted below the slide plate.
Ved bruk blir åpningene (boringene) erodert åv det varme metall og reparasjoner blir så utført slik at komponéntene,- særlig de mer kostbare'faste og forskyve plater, kan brukes på During use, the openings (bores) are eroded by the hot metal and repairs are then carried out so that the components, especially the more expensive fixed and movable plates, can be used on
nytt. new.
Bruken åv prefabrikerte profiler som innsettes i brukte plater til. fornyelse av boringen er velkjent. Slike innsatser har ringformet tverrsnitt og. i.nnskyves i .et . hulrom som dannes ved utboring av-det slitte parti av den brukte plate.rundt den opprinnelige boring. Ved sleideplaten vil en slik utboring The use of prefabricated profiles that are inserted into used panels for renewal of the drilling is well known. Such inserts have an annular cross-section and. i.nnshyves in .et . cavity formed by drilling out the worn part of the used plate around the original bore. In the case of the slide plate, such a bore will
vanligvis strekke seg forbi selve platen og inn i den underlig--gende samledyse, og den innsatte sylinder har en slik høyde at den strekker'seg fra den. nylig utformede overflate i dysehuset ' til sleideplatens . arbeidsflate ' Overflatene - mellom' innsatsens bunn og dysen, samt mellom dysens vertikale sider og platen forbindes ved-hjelp -av en ildfast sement. usually extend past the plate itself and into the underlying collecting nozzle, and the inserted cylinder has such a height that it extends from it. newly designed surface in the nozzle housing' to that of the slide plate. working surface The surfaces between the bottom of the insert and the nozzle, as well as between the vertical sides of the nozzle and the plate are connected with the help of a refractory cement.
En ulempe med et slikt arrangement er at vertikal bevegelse av den sylindriske innsats kan finne sted enten under bruk eller. under etterfølgende avkjøling av systemet... A disadvantage of such an arrangement is that vertical movement of the cylindrical insert can take place either during use or. during subsequent cooling of the system...
En annen; ulempe er at sleideplatens bevegelse under bruk -. -ofte kan' bringe' sementforbindelsen mellom innsatsen og platen tvers- over boringen, i, den stasjonære, øvre plate, slik at for-bindelsen, frilegges for smelte.t metall og således utsettes for - erosjon.... Another; disadvantage is that the sliding plate's movement during use -. - often the cement connection between the insert and the plate can be brought across the bore, in, the stationary, upper plate, so that the connection is exposed to molten metal and thus exposed to - erosion....
En-tredje ulempe er at den sylindriske .innsats veggtyk-keise begrenses av sleideplatens, geometri i visse systemer, hvilket fører til at en reparert" plates- nyttb.ar-e levetid begren ses tii det.punkt hvor erosjonen i åpningen'når frem til sement f orbindelsen. A third disadvantage is that the cylindrical insert wall thickness is limited by the geometry of the slide plate in certain systems, which means that the service life of a repaired plate is limited at the point where the erosion in the opening reaches to cement for the connection.
Det er et formål med denne oppfinnelse å tilveiebringe en forbedret■ildfast komponent for å redusere dette problem. It is an object of this invention to provide an improved refractory component to reduce this problem.
Ifølge et aspekt ved- foreliggende oppfinnelse- tilveiebrin-ges ■ en ; prefabrikert, flat, langstrakt, ildfast innsats av'tilnærmet eliptisk form med■en gjennomgående sirkulær boring. Mens. således, ifølge denne.oppfinnelse, innsatsens dimensjon vinkelrett på lengdeaksen kan begrenses av den tilsvarende platedimensjon, kan innsatsens lengde være slik at den er større.enn mekanismens langsgående bevegelse, hvorved'sementforbindelsen blir liggende utenfor området der.metall angripes According to one aspect of the present invention, ■ a ; prefabricated, flat, elongated, refractory insert of approximately elliptical shape with a continuous circular bore. While. thus, according to this invention, the dimension of the insert perpendicular to the longitudinal axis can be limited by the corresponding plate dimension, the length of the insert can be such that it is greater than the longitudinal movement of the mechanism, whereby the cement connection remains outside the area where the metal is attacked
og den andre og tredje ulempe ved den sylindriske.innsats eli-mineres. På grunn av innsatsens økede.masse og dens brede, and the second and third disadvantages of the cylindrical insert are eliminated. Due to the insert's increased mass and its wide,
bunn vil dessuten muligheten før vertikal bevegelse bli vesent-lig redusert.. bottom, the possibility of vertical movement will also be significantly reduced.
Imidlertid kan en slik- løsning gi et svakt punkt i enhe-ten ved innsatsens nedre overflate der den ligger an.mot den øvre, overflate på den utstikkende samledyse. Dersom turbulens. . oppstår i metallet under drift ■ kan denne horisontale: bane ut-gjøre en potensiell lekkasjerute for. smeltet metall dersom se-, ment.forbindelsen blir angrepet eller løsner. Ifølge et annet aspekt' ved foreliggende oppfinnelse til- • véiebringes følgelig en prefabrikert, enhetlig.ildfast komponent, T-fornie.t i sideriss og omfattende et parallellsidet- langstrakt hode'og en stamme med sirkulært tverrsnitt', idet en' However, such a solution can give a weak point in the unit at the lower surface of the insert where it rests against the upper surface of the protruding collecting nozzle. If turbulence. . occurs in the metal during operation ■ this horizontal path can constitute a potential leakage route for. molten metal if the cement connection is attacked or loosens. According to another aspect' of the present invention to- • a prefabricated, uniform refractory component, T-shaped in side view and comprising a parallel-sided elongated head and a trunk with a circular cross-section, is therefore provided,

fra den rette flate på platens andre side, kan være omgitt av en metallkappe, idet det hele danner en sleideplate/samle- .' dyseenhet.. from the straight surface on the other side of the plate, can be surrounded by a metal sheath, the whole forming a sliding plate/collector.' nozzle unit..

I -første rekke- vil innsatsen bli brukt i reparerte -plater, ■ -Primarily- the effort will be used in repaired -plates, ■
■men den kan alternativt anvendes i hye. eller originale plater., idet innsatsen etter bruk lett kan fjernes og en annen innføres slik åt utskjæring og boring.blir unødvendig. ■but it can alternatively be used in hye. or original plates., as the insert can be easily removed after use and another inserted so that cutting and drilling becomes unnecessary.
Innsatsen trenger ikke nødvendigvis være pre.fabrikert, og■ oppfinnelsen omfatter også en modifikasjon av de forskjellige ovennevnte aspekter der innsatsen, enten flat eller -T-formet, The insert does not necessarily have to be prefabricated, and■ the invention also includes a modification of the various above-mentioned aspects where the insert, either flat or T-shaped,
