Description
Oppfinnelsen angår et skyveportlukke for styring av tapping av flytende metall fra en bunntappingsbeholder, omfattende et ildfast portlegeme med en åpning og et samlemunnstykke som er montert i ett stykke med portlegemet og rager nedover fra åpningen, hvor munnstykket omfatter et rør av ildfast materiale som har forholdsvis høy varmeledningsevne og som motstår erosjon under uttappingen av flytende metall, en metallkappe som omgir røret og et lag av ildfast sement mellom røret og kappen. The invention relates to a sliding gate valve for controlling the tapping of liquid metal from a bottom tapping container, comprising a refractory gate body with an opening and a collecting nozzle which is mounted in one piece with the gate body and projects downwards from the opening, the nozzle comprising a tube of refractory material having relatively high thermal conductivity and which resists erosion during the pouring of liquid metal, a metal jacket surrounding the pipe and a layer of refractory cement between the pipe and the jacket.
Innenfor det område av teknikken som angår skyveport-lukker for bunntappingsbeholdere, er et "samlemunnstykke" et ildfast rør som er montert i ett stykke med en port og strekker seg nedover fra en åpning i porten for å avgrense strømmen av smeltet metall når denne utstøpes av bunntappingsåpningen, og opp-rettholde en forholdsvis tett strøm. Det kan f.eks. henvises til BRD off. skrift nr. 2 227 501 som viser en lukkemekanisme med en skyveport som er særlig beregnet for bruk for støpeøser og som er utstyrt med et samlemunnstykke. In the art of sliding gate closures for bottom tapping vessels, a "header" is a refractory tube integrally fitted with a gate and extending downwardly from an opening in the gate to confine the flow of molten metal as it is poured from the bottom tapping opening, and maintain a relatively dense flow. It can e.g. refer to BRD off. document no. 2 227 501 which shows a closing mechanism with a sliding gate which is particularly intended for use for ladles and which is equipped with a collecting nozzle.
Vanlig praksis er å benytte et erosjonsbestandig, ildfast materiale i et samlemunnstykke. Det ildfaste materiale ved den øvre del av munnstykket i umiddelbar nærhet av porten må være i stand til å motstå erosjon av en strupt utstøpingsstrøm, og ildfaste materialer med høyt innhold av aluminiumoxyd blir vanligvis benyttet. Erosjonsbestandige, ildfaste materialer har imidlertid forholdsvis høy varmeledningsevne som gjør disse mindre ønskelige for den nedre del eller uttappingsenden av munnstykket. Dråper av det utstøpte metall har en tendens til å størkne på uttappingsenden og danne vulster eller opphøyde partier som avbøyer utstø-pingsstrømmen. Sådanne vulster eller partikler av størknet metall faller iblant av og forurenser metallet i den opptagende beholder. Et samlemunnstykke som er kraftig tilgrodd av sådanne størknede partikler, må tas ut av bruk, og hele delen, medregnet portpla-ten, må skrapes. Common practice is to use an erosion-resistant, refractory material in a collection nozzle. The refractory material at the upper part of the nozzle in the immediate vicinity of the port must be able to resist erosion by a choked casting stream, and refractory materials with a high aluminum oxide content are usually used. Erosion-resistant, refractory materials, however, have relatively high thermal conductivity, which makes them less desirable for the lower part or discharge end of the nozzle. Drops of the cast metal tend to solidify on the withdrawal end and form beads or raised portions which deflect the casting flow. Such beads or particles of solidified metal sometimes fall off and contaminate the metal in the receiving container. A collecting nozzle that is heavily overgrown with such solidified particles must be taken out of use, and the entire part, including the gate plate, must be scraped.
Formålet med oppfinnelsen er å tilveiebringe et skyveportlukke hvor de ovenfor omtalte ulemper er eliminert. Dette oppnås ved et skyveportlukke av den innledningsvis angitte type som ifølge oppfinnelsen er kjennetegnet ved at det er anordnet en avtagbar og utskiftbar spiss av kort lengde og en anordning for befestigelse av spissen ved rørets nedre ende, idet spissen er dannet av en ring av ildfast materiale som har dårligere varmeledningsevne enn det ildfaste materiale i røret, og en metallmantel omgir i det minste den øvre del av ringen. The purpose of the invention is to provide a sliding door where the disadvantages mentioned above are eliminated. This is achieved by a sliding gate valve of the type indicated at the outset which, according to the invention, is characterized by the fact that there is a removable and replaceable tip of short length and a device for attaching the tip to the lower end of the pipe, the tip being formed by a ring of refractory material which has poorer thermal conductivity than the refractory material in the pipe, and a metal jacket surrounds at least the upper part of the ring.
Spissen ifølge oppfinnelsen kan kasseres når erosjon opptrer eller når spissen ikke lenger er brukbar. Oppfinnelsen tillater utvelgelse av et ildfast materiale som er særlig egnet for å hindre størkning av metalldråper ved uttappingsenden av samlemunnstykket. The tip according to the invention can be discarded when erosion occurs or when the tip is no longer usable. The invention allows the selection of a refractory material which is particularly suitable for preventing solidification of metal droplets at the discharge end of the collecting nozzle.
Oppfinnelsen skal beskrives nærmere i det følgende ved hjelp av et utførelseseksempel under henvisning til tegningen, der fig. 1 er et vertikalsnitt som viser en del av en skyveportmekanis-me som er forsynt med et samlemunnstykke ifølge oppfinnelsen, fig. 2 er et sideriss etter linjen II - II på fig. 1, fig. 3 er et ufullstendig riss som likner fig. 1, men som viser en modifisert utførelse, og fig. 4 er et annet ufullstendig riss som likner fig. 1, men som viser en ytterligere modifikasjon. The invention will be described in more detail in the following by means of an embodiment with reference to the drawing, where fig. 1 is a vertical section showing part of a sliding gate mechanism which is provided with a collecting nozzle according to the invention, fig. 2 is a side view along the line II - II in fig. 1, fig. 3 is an incomplete view similar to FIG. 1, but which shows a modified embodiment, and fig. 4 is another partial view similar to FIG. 1, but showing a further modification.
Fig. 1 viser skjematisk en topplate 10 og en skyveport 12 som utgjør en del av en kjent mekanisme for styring av utstø-pingen av flytende metall fra en bunntappingsbeholder. Topplaten Fig. 1 schematically shows a top plate 10 and a sliding gate 12 which form part of a known mechanism for controlling the pouring of liquid metal from a bottom tapping container. Top plate
10 er fremstilt av et ildfast legeme 13 og en metallramme 14 10 is made of a refractory body 13 and a metal frame 14
og har en utstøpingsåpning 15. Porten 12 er dannet av et ildfast legeme 16, en metallramme 17 og et lag av ildfast sement 18 mellom legemet og rammen. Porten omfatter et integrert, nedadragende samlemunnstykke 19. Munnstykket er dannet av et erosjonsbestandig, ildfast rørlegeme 20, en metallkappe 21 som omgir rørlegemet og et lag 22 av ildfast sement mellom rørlegemet og kappen. Røret strekker seg gjennom en åpning i portens ildfaste legeme 16, og dets øvre ende er i flukt med den øvre overflate av porten. Det ildfaste materiale i rørlegemet har vanligvis høyt aluminiuminn-hold, dvs. ca. 70 - 95 vekt% A^O^, men også andre materialer kan benyttes, såsom magnesiumoxyd eller en magnesiumoxyd-kromblanding. and has a casting opening 15. The gate 12 is formed by a refractory body 16, a metal frame 17 and a layer of refractory cement 18 between the body and the frame. The gate comprises an integrated, downward-drafting collection nozzle 19. The nozzle is formed by an erosion-resistant, refractory pipe body 20, a metal jacket 21 which surrounds the pipe body and a layer 22 of refractory cement between the pipe body and the jacket. The tube extends through an opening in the gate's refractory body 16, and its upper end is flush with the upper surface of the gate. The refractory material in the pipe body usually has a high aluminum content, i.e. approx. 70 - 95% by weight A^O^, but other materials can also be used, such as magnesium oxide or a magnesium oxide-chromium mixture.
I overensstemmelse med oppfinnelsen omfatter uttappingsenden av samlemunnstykket 19 en løsbar og utskiftbar spiss 21. Spissen er dannet av en ildfast ring 24, en metallmantel 25 som omgir ringen, og et lag 26 av ildfast sement mellom ringen og mantelen. Ringen danner en fortsettelse av rørlegemet 20 og den øvre overflate av ringen har en forsenkning 27 som opptar bunnen av rørlegemet. Spissen er festet til hoveddelen av munnstykket med et metallbånd 28 som omgir delene ved disses sammenføyning. Bån-dets ender holdes sammen ved hjelp av en bolt 29. Fig. 3 viser en modifikasjon hvor spissen er festet med fjærklemmer 30. Klemmene er utformet i ett stykke med mantelen 25a og strekker seg oppover fra denne, idet de opptas i spor 31 i kappen 21a. Fig. 4 viser en annen modifikasjon hvor spissen ved hjelp av gjenger er festet til munnstykkets hoveddel. Kappen og mantelen 21b henholdsvis 25t> har skruegjenger 32 som griper inn i hverandre. In accordance with the invention, the dispensing end of the collecting nozzle 19 comprises a detachable and replaceable tip 21. The tip is formed by a refractory ring 24, a metal jacket 25 which surrounds the ring, and a layer 26 of refractory cement between the ring and the jacket. The ring forms a continuation of the tubular body 20 and the upper surface of the ring has a recess 27 which occupies the bottom of the tubular body. The tip is attached to the main part of the mouthpiece with a metal band 28 which surrounds the parts when they are joined. The ends of the web are held together by means of a bolt 29. Fig. 3 shows a modification where the tip is attached with spring clamps 30. The clamps are formed in one piece with the mantle 25a and extend upwards from this, being received in grooves 31 in cape 21a. Fig. 4 shows another modification where the tip is attached to the main part of the mouthpiece by means of threads. The cap and mantle 21b and 25t respectively have screw threads 32 that engage each other.
Det ildfaste materiale i ringen 24 har lavere varmeledningsevne enn det ildfaste materiale i rørlegemet 20. Dersom et ildfast materiale med aluminiumoxyd benyttes i ringen, er det mak-simale A^O^-innhold vesentlig mindre enn innholdet av A^O^ i rørlegemet 20. Eksempler på ildfaste materialer som kan tilsettes til aluminiumoxydinnholdet i ringen, er ildfast leire og på nytt bundet ("rebonded"), smeltet siliciumoxyd. Det er mye mindre sannsynlighet for at dråper av det utstøpte metall skal størkne på disse ildfaste materialer, enn på det erosjonsbestandige, ildfaste materiale i rørlegemet 20. Spissen 23 er et lite stykke og har kort lengde, og den kan erstattes med forholdsvis liten kostnad når den blir forvitret eller ødelagt. Et antall spisser som er fremstilt av forskjellige ildfaste materialer, kan lagres, og det kan installeres en spiss av det optimale ildfaste materiale for utstøping av hvilket som helst spesielt metall. The refractory material in the ring 24 has a lower thermal conductivity than the refractory material in the pipe body 20. If a refractory material with aluminum oxide is used in the ring, the maximum A^O^ content is substantially less than the content of A^O^ in the pipe body 20 Examples of refractory materials that can be added to the aluminum oxide content of the ring are refractory clay and rebonded, fused silicon oxide. It is much less likely that drops of the cast metal will solidify on these refractories than on the erosion-resistant refractory material in the tube body 20. The tip 23 is a small piece and has a short length, and it can be replaced at relatively little cost when it gets weathered or destroyed. A number of tips made of different refractory materials can be stored and a tip of the optimum refractory material can be installed for casting any particular metal.
