Innretning til tilførsel av smøremiddel ved ful lkont muer Hg Device for supply of lubricant at ful lcont muer Hg
støpning av metaller i stasjonære kokiller. casting of metals in stationary moulds.
Oppfinnelsen vedrOrer en innretning for tilfOrsel av smoremiddel ved helkontinuerlig stOping av metaller i stasjonære kokiller hvor smOremidlet tilfares til kokillen gjennom et porOst materiale. The invention relates to a device for supplying lubricant by fully continuous pouring of metals into stationary molds where the lubricant is supplied to the mold through a porous material.
Ved en kjent fremgangsmåte av denne type tilfores smOremidlet gjennom kokilleveggen i nærheten av det sted hvor metallet trer inn, og som på dette sted består av et porOst materiale som grafit eller sintret kobber. InnfOringen av smOremidlet foregår da med en pumpe som presser det gjennom den porOse, ikke kjOlte kokillevegg inn i kokillens indre. Ved denne arbeidsmåte kommer smOremidlet i det vesentlige flytende inn i kokillens indre, hvilket ved unøyaktig dosering eller ved driftsforstyrrelser på grunn av plutselig fordampning kan gi anledning til dannelse av ikke feil-frie strenger eller sogar kan fOre til avbrudd i stopeprosessen. In a known method of this type, the lubricant is supplied through the mold wall near the place where the metal penetrates, and which at this place consists of a porous material such as graphite or sintered copper. The introduction of the lubricant then takes place with a pump that pushes it through the porous, uncooled mold wall into the interior of the mold. In this way of working, the lubricant essentially enters the interior of the mold in a liquid form, which in the case of inaccurate dosing or in the event of operational disturbances due to sudden evaporation can give rise to the formation of non-flawless strings or even lead to an interruption in the stopping process.
For ved denne arbeidsmåte å oppnå et sikkert arbeidsforlOp er det nOdvendig med anvendelsen av en omstendelig presisjonspumpe, og man er allikevel ikke alltid sikker på at driften foregår uten forstyr-relser. In order to achieve a safe working process with this method of working, it is necessary to use a complicated precision pump, and even then it is not always certain that the operation takes place without disturbances.
Oppfinnelsen vedrorer en innretning for tilforsel The invention relates to a device for supply
av smoremiddel ved helkontinuerlig vannrett eller loddrett strengstoping av metaller i stasjonære kokiller, hvor smOremidlet innfores i kokillen ved vekevirkning gjennom et porOst materiale, og innretningen erkarakterisert veden av nevnte porOse materiale bestående metalltilforingsdel, hvorfra smOremidlet fordamper inn i et hulrom som danner seg mellom metallet, den avgrensende kokillevegg og den tilstotende vegg av metalltilfOringsdelen og hvorfra det fores ut med stOpestrengen etter kondensasjon på denne del av veggen og smorer såvel kokillen som også strengens overflate, idet smOremidlet innfores i en kanal som er utformet i kokillens bak- of lubricant by completely continuous horizontal or vertical string stuffing of metals in stationary molds, where the lubricant is introduced into the mold by bending action through a porous material, and the device is characterized by a metal supply part consisting of said porous material, from which the lubricant evaporates into a cavity that forms between the metal, the bounding mold wall and the adjacent wall of the metal supply part and from where it is fed out with the casting string after condensation on this part of the wall and lubricates both the mold and the surface of the string, the lubricant being introduced into a channel that is designed in the back of the mold
vegg og som er åpen mot den porose metalltilfOringsdel. wall and which is open to the porous metal supply part.
Denne innretning ifOlge oppfinnelsen byr i fOrste rekke på det fortrinn at smoringen foregår automatisk, uten an-vendelse av en komplisert pumpe, på grunn av den oppnådde vekevirkning, idet det sikres at den tilforte smOremiddelmengde i et-hvert tilfelle tilsvarer kravene og at intet overtrykk opptrer som ville resultere i at strengen ble fjernet fra kokilleveggen, og dermed ville kunne fore til forstyrrelse av stopeprosessen. This device according to the invention primarily offers the advantage that the lubrication takes place automatically, without the use of a complicated pump, due to the softening effect achieved, ensuring that the added amount of lubricant in each case corresponds to the requirements and that there is no overpressure acts which would result in the strand being removed from the mold wall, and thus could lead to disruption of the stoping process.
Ifolge oppfinnelsen innfores smoremidlet i dampform According to the invention, the lubricant is introduced in vapor form
i hulrommet som danner seg mellom metallet og de tilgrensende steder. Det i dette hulrom på kokillens avkjOlte arbeidsflate kondenserte sraOremiddel medfores av strengen og sikrer en god smOring over den samlede kokilleflate, og det oppnås en god stOp. in the cavity that forms between the metal and the adjacent places. The coolant condensed in this cavity on the cooled working surface of the mold is carried along by the string and ensures good lubrication over the entire mold surface, and a good stop is achieved.
To utforelsesformer av en kokille som er egnet for utfOrelse av fremgangsmåten ifolge oppfinnelsen, er vist på tegnin-gen. Two embodiments of a mold suitable for carrying out the method according to the invention are shown in the drawing.
Fig* 1 viser et utsnitt av en vannavkjOlt gjennomlOpskokille som kan anvendes til horisontal strengstOpning. Kokilleveggen 1 er avkjOlt ved hjelp av en vannmantel 2. I kokillen trer flytende metall gjennom åpningen 4 i en metalltilfOringsdel 5 fra beholderen 6. Det danner seg et fast skall 7 med en flytende kjerne 8. Det flytende metall fyller på grunn av sin overflatespenning ikke ut hjornet mellom kokilleveggen 1 og metalltilfOringsdelen 5*Fig* 1 shows a section of a water-cooled through-flow die that can be used for horizontal string filling. The mold wall 1 is cooled by means of a water jacket 2. In the mold, liquid metal passes through the opening 4 in a metal supply part 5 from the container 6. A solid shell 7 is formed with a liquid core 8. Due to its surface tension, the liquid metal does not fill out the corner between the mold wall 1 and the metal supply part 5*
Det danner seg et hulrom 9»I en avstand av noen millimeter fra A cavity 9" forms at a distance of a few millimeters from
dette hulrom 9 er det i kokillens bakvegg anordnet kanaler 10 som er lukket av metalltilfOringsdelen 5«Platen 5 består av porost varmebeståndig materiale, således at den oppsuger et smoremiddel som gjennom tilfOrselskanaler bringes inn i kanalen 10. in this cavity 9, channels 10 are arranged in the rear wall of the mold which are closed by the metal supply part 5. The plate 5 consists of porous heat-resistant material, so that it absorbs a lubricant which is brought into the channel 10 through supply channels.
Det oppsugde smoremiddel kommer også til den del av metalltilfOringsdelen 5 ^ om begrenéér hulrommet 9»Denne del av metalltilfOringsdelen 5 oppvarmes av det flytende metall, hvorved smOremidlet fordampes. Det fordampede smOremiddel fyller hulrommet 9 og kondenserer på den frie overflate av den vannavkjOlede kokillevegg 1. Ved vekevirkning i metalltilfOringsdelen 5 mellom kanalen 10 og hulrommet 9 blir nytt smoremiddel kontinuerlig fOrt til hulrommet 9°S dermed også til overflaten av kokilleveggen 1. MetalltilfOringsdelen 5 kan dessuten mest hensiktsmessig deles ved hjelp av en folie 11, eksempelvis av aluminium, som er ugjennomtrengelig for smOremidlet foråt smOremidlet ikke skal trenge inn i andre deler av innretningen. The absorbed lubricant also reaches the part of the metal supply part 5 that delimits the cavity 9. This part of the metal supply part 5 is heated by the liquid metal, whereby the lubricant evaporates. The vaporized lubricant fills the cavity 9 and condenses on the free surface of the water-cooled mold wall 1. In the event of a wicking effect in the metal supply part 5 between the channel 10 and the cavity 9, new lubricant is continuously transported to the cavity 9°S and thus also to the surface of the mold wall 1. The metal supply part 5 can moreover, it is most expediently divided by means of a foil 11, for example of aluminium, which is impermeable to the lubricant so that the lubricant does not penetrate into other parts of the device.
Som det fremgår av fig'. 2 er innretningen også egnet As can be seen from fig'. 2, the device is also suitable
for loddrett strengstOpning i vannavkjOlte gjennomlOpskokiller. for vertical string filling in water-cooled through-flow chillers.
Figuren viser et utsnitt av en slik kokille med kokillevegg 1 og vannmantel 2. Den Ovre del av kokilleveggen er dekket ved hjelp av en metalltilfOringsdel 5 av porOst varmebeståndig materiale. Det danner seg likeledes et hulrom 9»hvori smOremidlet trer inn fra kanalen 10. The figure shows a section of such a mold with mold wall 1 and water jacket 2. The upper part of the mold wall is covered with the help of a metal supply part 5 of porous heat-resistant material. A cavity 9" is also formed into which the lubricant enters from the channel 10.
