Kupititsa patsogolo Chitetezo Chamafakitale ndi Kuchita Bwino Pogwiritsa Ntchito Ma Graphite Crucibles Moyenera

dongo Graphite Crucible

M'zaka zaposachedwapa, ntchito yagraphite cruciblesm'mafakitale kusungunula zitsulo ndi kuponya kwakhala kukuchulukirachulukira, chifukwa cha mapangidwe awo opangidwa ndi ceramic omwe amapereka kukana kwapadera kwa kutentha kwambiri. Komabe, pakugwiritsa ntchito moyenera, ambiri amanyalanyaza njira yofunika kwambiri yotenthetsera ma graphite crucibles atsopano, zomwe zimapangitsa kuti pakhale ngozi pachitetezo chaumwini ndi katundu chifukwa cha thyoka. Kuti tiwonjezere phindu la ma graphite crucibles, timapereka malingaliro ozikidwa pa sayansi kuti agwiritse ntchito moyenera, kuwonetsetsa kuti kupanga bwino komanso chitetezo cha mafakitale.

Makhalidwe a Graphite Crucibles

Ma graphite crucibles amatenga gawo lofunikira pakusungunula ndi kuponya zitsulo chifukwa cha matenthedwe ake apamwamba. Ngakhale amawonetsa matenthedwe abwinoko poyerekeza ndi ma silicon carbide crucibles, amatha kukhala ndi okosijeni ndipo amakhala ndi kusweka kwakukulu. Kuti tithane ndi mavutowa, ndikofunikira kugwiritsa ntchito njira yotenthetsera yasayansi yomveka bwino.

Malangizo a Preheating

  1. Kuyika pafupi ndi Ng'anjo ya Mafuta Yotenthetsera: Ikani crucible pafupi ndi ng'anjo yamafuta kwa maola 4-5 musanayambe kugwiritsa ntchito. Njira yotenthetserayi imathandizira kutulutsa chinyezi, kumapangitsa kuti crucible ikhale yokhazikika.
  2. Kuwotcha Makala Kapena nkhuni: Ikani makala kapena nkhuni mkati mwa mphira ndikuwotcha pafupifupi maola anayi. Sitepe iyi imathandizira kuchotsa chinyezi komanso imathandizira kukana kutentha kwa crucible.
  3. Kutentha kwa ng'anjo: Panthawi yotentha koyambirira, pang'onopang'ono onjezerani kutentha kwa ng'anjo kutengera magawo otsatirawa a kutentha kuti mutsimikizire kukhazikika ndi moyo wautali wa crucible:
    • 0 ° C mpaka 200 ° C: Kutentha pang'onopang'ono kwa maola 4 (ng'anjo yamafuta) / magetsi
    • 0 ° C mpaka 300 ° C: Kutentha pang'onopang'ono kwa ola limodzi (magetsi)
    • 200 ° C mpaka 300 ° C: Kutentha pang'onopang'ono kwa maola 4 (ng'anjo)
    • 300 ° C mpaka 800 ° C: Kutentha pang'onopang'ono kwa maola 4 (ng'anjo)
    • 300 ° C mpaka 400 ° C: Kutentha pang'onopang'ono kwa maola anayi
    • 400 ° C mpaka 600 ° C: Kutentha kofulumira, kusunga kwa maola awiri
  4. Post Shutdown Reheating: Pambuyo potseka, nthawi yotenthetsera mafuta ndi ng'anjo yamagetsi ndi motere:
    • 0 ° C mpaka 300 ° C: Kutentha pang'onopang'ono kwa ola limodzi
    • 300 ° C mpaka 600 ° C: Kutentha pang'onopang'ono kwa maola anayi
    • Pamwamba pa 600°C: Kutentha kofulumira mpaka kutentha kofunikira

Malangizo Otseka

  • Kwa ng'anjo zamagetsi, ndikofunikira kuti muzisunga zotsekereza mosalekeza mukakhala osagwira ntchito, kutentha kumayikidwa mozungulira 600 ° C kuti mupewe kuzirala mwachangu. Ngati kutchinjiriza sikungatheke, chotsani zinthu mu crucible kuti muchepetse zotsalira.
  • Kwa ng'anjo zamafuta, mutatha kuzimitsa, onetsetsani kuti mwatulutsa zinthu momwe mungathere. Tsekani chivundikiro cha ng'anjo ndi madoko olowera mpweya kuti muteteze kutentha kotsalira komanso kupewa chinyezi chodumphadumpha.

Potsatira malangizo asayansi oyambira kutentha ndi kutsekeka, magwiridwe antchito abwino a ma graphite crucibles popanga mafakitale atha kutsimikizika, munthawi yomweyo kupititsa patsogolo kupanga bwino ndikuteteza chitetezo cha mafakitale. Tiyeni tonse tidzipereke ku luso laukadaulo kuti tithandizire kupita patsogolo kwa mafakitale.
