Tela jatkuvaan valuun tarkoltettua laitetta vårtenRoller for continuous casting equipment
Taman keksinndn kohde on tela jatkuvaan valuun tar-koitettua laitetta vårten, jossa laitteessa valetaan ohui-5 ta liuskoja suoraan sulasta metalllsta kahden telan vaiissa tal yhdelia telalla, joka tela kdsittaa sylinterimaisen ytimen, joka on paailystetty ensimmaiselia vaipalla, ja jaahdytyskanavat, jotka ovat valpan ja ytimen vaiissa tai valpassa.The object of the present invention is a roll for a continuous casting apparatus in which thin strips of molten metal are cast directly on a roll of two rolls with a single roll comprising a cylindrical core embedded in a first shell and cooling channels which are in the silence or vigilance of the nucleus.
10 Kuten tunnettua, ndma telat sisaitavat sylinter!- maisen ytimen, joka on paailystetty vaipalla, joka taval-lisesti on tehty kuparista, ja niita jaahdytetaan kierrat-tamana jaahdytysnestetta kuten vetta kanavissa, jotka ovat vaipan ja ytimen vaiissa tai vaipassa. Itse asiassa 15 on havaittu, etta taiia tavalla tuotetut telat pullistu-vat valun aikana ulos pain siten, etta kahden taiia tavalla pullistuneen telan vaiissa valetuilla tuotteilla on "koiran luun" muotoinen profiili. Sellaisten tuotteiden paksuus reunoilla on suurempi kuin niiden paksuus keski-20 linjalla ja ne ovat siksi epatyydyttavia.As is known, ndma rolls contain a cylindrical core which is corrugated in a jacket, usually made of copper, and are cooled by circulating a coolant such as water in channels in the jacket or jacket of the jacket and core. In fact, it has been found that the rolls produced in such a way bulge out during casting, so that the products cast in the stems of the two rolls rolled in such a way have a "dog bone" -shaped profile. The thickness of such products at the edges is greater than their thickness at the mid-20 line and they are therefore unsatisfactory.
Kun on kyseessa valu yhdelia telalla, telan pul-listuminen tekee telan ja sulan metallin syOttdlaitteen valin epatasaiseksi. Tela voi siksi joutua kosketukseen tulen kestavan syOttOlaitteen kanssa ja vahingoittaa sita.In the case of single casting on a roll, the bulging of the roll makes the choice of roll and molten metal feeder uneven. The roller may therefore come into contact with and damage the fire-resistant feeder.
25 KeksinnOn tarkoitus on tuottaa teloja, jotka teke- vat mahdolliseksi taman haitan poistamisen, ja siten saada aikaan valuja, joiden profiililla on tyydyttava paksuus.The object of the invention is to provide rolls which make it possible to eliminate this disadvantage and thus to provide castings with a satisfactory profile thickness.
Nama paamaarat saavutetaan keksinnOn mukaisella telalla, jolle on tunnusomaista, etta tela kasittaa ensim-30 maisen vaipan ymparille sovitetun toisen vaipan, joka yh-dessa ensimmaisen vaipan kanssa muodostaa kaksi paailek-kaista sylinterimaista kerrosta, joiden materlaalit on valittu siten, etta sisemmaiia vaipalla on suurempi lampd-laajenemiskerroin kuin ulommalla vaipalla, joka on koske-35 tuksessa sulan metallin kanssa.These bales are achieved by a roll according to the invention, characterized in that the roll casts a second sheath arranged around the first sheath, which together with the first sheath forms two patchy cylindrical layers, the materials of which are chosen so that the inner sheath is larger. coefficient of lampd expansion than the outer sheath in contact with the molten metal.
22
Lampdlaajenemiskertoimet ja siten vastaavat mate-riaalit valitaan siten, etta naiden kahden materiaalin laajenemisero poistaa talla tavoin valmistetun kaksois-vaipan taipumuksen pullistua, erityisesti kahden telan 5 vaiisen tilan tasolla.The coefficients of lamp expansion and thus the corresponding materials are chosen so that the difference in expansion between the two materials eliminates the tendency of the double sheath thus produced to bulge, especially at the level of the 5-roll state of the two rolls.
Sisempi vaippa voi olla tehty esimerkiksi kuparista kun taas ulompi vaippa on tehty teraksesta ja nama vaipat on juotettu toisiinsa.The inner sheath may be made of copper, for example, while the outer sheath is made of steel and these sheaths are soldered together.
KeksinnOn mukaisen telan edulliset suoritusmuodot 10 ilmenevat oheisista epaitsenaisista patenttivaatimuksista 2-3.Preferred embodiments of the roll 10 according to the invention appear from the appended claims 2-3.
Keksinndn muut ominaisuudet ja edut kayvat ilmi seuraavasta kuvauksesta, jossa viitataan liitteena oleviin piirustuksiin, jotka havainnollistavat ei rajoittavaa to-15 teutusmuotoa esimerkin omaisesti.Other features and advantages of the invention will be apparent from the following description, taken in conjunction with the accompanying drawings, which illustrate a non-limiting embodiment by way of example.
Kuvio 1 on perspektiivikuva telasta, joka kasittaa keksinnOn mukaisen kaksoisvaipan ja joka on tarkoitettu ohuiden metallisuikaleiden jatkuvavalulaitteeseen.Figure 1 is a perspective view of a roll covering a double jacket according to the invention for a continuous casting machine for thin metal strips.
Kuvio 2 on aksiaalinen osittaisleikkaus kuvion 1 20 telasta.Figure 2 is an axial partial section of the roll of Figure 1.
Piirustuksissa esitetty tela 1 on tarkoitettu su lan metallin kuten teraksen jatkuvavalulaitteeseen, jolla valetaan ohuita metallisuikaleita kahden samanlaisen telan 1 vaiissa. Tailainen laite on sindnsa hyvin tunnettu eika 25 sita siksi ole esitetty.The roll 1 shown in the drawings is intended for a continuous casting device for molten metal such as steel, by means of which thin strips of metal are cast in the coils of two similar rolls 1. Such a device is well known and therefore not shown.
Tela 1, jonka akseli on XX, koostuu sisaiia olevas-ta ytimesta 2 ja kahdesta paailekkaisesta rengasmaisesta vaipasta 3 ja 4, jotka ympardivat sisaiia olevaa ydinta 2, johon on tehty jaahdytyskanavat, joissa vesi voi kiertaa. 30 Paallekkain asetettujen kerrosten 3 ja 4 materiaalit vali taan siten, etta sisemmaiia vaipalla 3 on suurempi lampd-laajenemiskerroin kuin ulommalla vaipalla 4, joka on kos-ketuksessa sulaan metalliin.The roll 1, the axis of which is XX, consists of an inner core 2 and two patchy annular sheaths 3 and 4 which surround an inner core 2 into which cooling channels have been made in which water can circulate. The materials of the superimposed layers 3 and 4 are selected such that the inner sheath 3 has a higher coefficient of lampd expansion than the outer sheath 4 in contact with the molten metal.

91134 3 paaile tal elektrolyyttiselia pinnoituksella. Ei rajoitta-vana eslmerkklna sisempi vaippa 3 on valmistettu kuparista ja ulompi vaippa terSksesta, kun kuparilla todella on suu-rempi lampdlaaj enemiskerroin kuin terakselia.91134 3 Coat the electrolyte back with a coating. Without limitation, the inner sheath 3 is made of copper and the outer sheath is made of steel, while copper actually has a higher lamp coefficient than steel.
5 Kerrosten 3 ja 4 paksuudet saadetaan valittujen ma- teriaalien lampdlaajenemiskertoimien perusteella.The thicknesses of layers 3 and 4 are obtained on the basis of the lamp expansion coefficients of the selected materials.
Kun kaksoisvaippa 3, 4 saatetaan suuren lampdtila-gradientin alaiseksi sulan metallin koskettaessa ulompaa vaippaa 4, erilainen laajeneminen kerrosten 3 ja 4 kahden 10 materiaalin valilia poistaa kaksoisvaipan taipumuksen pul-listua erityisesti laitteen kahden telan vaiisen tilan tasolla.When the double jacket 3, 4 is subjected to a large lamp state gradient as the molten metal contacts the outer jacket 4, the different expansion of the material of the two materials 10 of layers 3 and 4 eliminates the tendency of the double jacket to bulge, especially at the level of the two rolls.
Sisempi vaippa on edullisesti valmistettu kuparista ja se on 5 - 30 mm paksu. Ulompi vaippa voidaan tehda te-15 r&ksest&, nikkelista tai kromista ja se on 1 - 10 mm paksu.The inner sheath is preferably made of copper and is 5 to 30 mm thick. The outer sheath can be made of te-15, nickel or chrome and is 1 to 10 mm thick.
Esimerkiksi: - tela: halkalsija 1 500 mm, leveys 800 mm - sisempi vaippa: kuparia, paksuus 15 mm 20 - ulompi vaippa: terasta tai nlkkelid; paksuus 2 mm - vaipat on juotettu toisiinsa koko pinnaltaan (ulompi vaippa koostuu sisemman vaipan pinnalle pinnoi-tetusta pinnoitteesta) - valettavan terdksen lampdtila 1 450° - sisemman 25 vaipan sisdseinan lSmpOtila: 60 °C (suurin piirtein sama kuin jaahdytysveden lampdtila).For example: - roll: diameter 1,500 mm, width 800 mm - inner casing: copper, thickness 15 mm 20 - outer casing: steel or nlkkelid; thickness 2 mm - the sheaths are soldered to each other over their entire surface (the outer sheath consists of a coating coated on the inner sheath) - cast steel lamp space 1,450 ° - inner 25 sheath inner wall temperature: 60 ° C (approximately the same as the cooling water lamp space).
tulos: telan pullistuma on 0,3 mm kun taas jos tela olisi tehty kokonaan kuparista, pullistuma olisi noin 1 mm.the result: the bulge of the roll is 0.3 mm while if the roll were made entirely of copper, the bulge would be about 1 mm.
30 Olisi mahdollista edelleen pienentaa jaijelle jaa- vaa pullistumaa valitsemalla paallysteeksi (ulommaksi vai-paksi) materiaali, jolla on pienempi lampdlaajenemiskerroin ja parempi låmmOn johtavuus, kuten esimerkiksi kromi.30 It would be possible to further reduce the bulge in the beam by choosing a material with a lower coefficient of lamp expansion and better thermal conductivity, such as chromium, as the bale layer (outer shell).
Lopuksi on huomattava, etta keksintO ei ole rajoi-35 tettu vain sovitelmaan, jossa jaahdytyskanavat 5 ovat 4 kaksoisvaipan (3, 4) alia, vaan nama kanavat voidaan myOs porata sisempaan vaippaan.Finally, it should be noted that the invention is not limited to an arrangement in which the cooling channels 5 are below the 4 double sheaths (3, 4), but these channels can also be drilled into the inner shell.
On myOs tarkoituksenmukaista huomauttaa, etta edelia mainitun kuparista tehdyn vaipan paksuus vastaa 5 tapausta, jossa jaahdytyskanavat on tehty taman vaipan alle. Jos kanavat on tehty sisempaan vaippaan, kyseessa oleva paksuus on naiden kanavien ja sisemmån/ulomman vaipan rajapinnan sateittainen etaisyys, silia tassa tapauk-sessa paksuus, joka jaa kanavien ja ytimen valiin, pysyy 10 matalassa lampOtilassa Ja silia on vain vahainen vaikutus erilaiseen lampOlaaJenemiseen.It is expedient to note that the thickness of the above-mentioned sheath made of copper corresponds to 5 cases in which the cooling channels are made under this sheath. If the ducts are made in the inner jacket, the thickness in question is the rainy distance between these ducts and the inner / outer jacket interface, in this case the thickness dividing between the ducts and the core remains at a low temperature and Silia has only a waxy effect on the different lamp expansion.
