Mavuto wamba ndi kusanthula kwa crucibles: kumasulira ma puzzles mu sayansi yazinthu

M'makampani amakono komanso kafukufuku wasayansi, ma crucibles amagwira ntchito yofunika kwambiri pakusungunula zitsulo, kuyesa kwamankhwala, ndi ntchito zina zambiri. Komabe,Crucible Kwa Kusungunulanthawi zambiri amakumana ndi mavuto osiyanasiyana pakagwiritsidwe ntchito, monga ming'alu yopingasa, ming'alu yakutali, ndi ming'alu yooneka ngati nyenyezi. Nkhaniyi ifotokoza za zovuta zomwe zimachitika ndi ma crucibles ndikuwunika zomwe zingathandize kuthetsa mavutowa.

Ming'alu yam'mbali pafupi ndi pansi pa chitsulo chosungunuka: Mtundu uwu wa ming'alu nthawi zambiri umapezeka pafupi ndi pansiKuponya cruciblendipo zitha kuchititsa kuti pansi pa crucible kugwe. Zifukwa zotheka ndi izi:

1. Panthawi ya preheating, kutentha kumakwera mofulumira kwambiri.
2. Gwiritsani ntchito chinthu cholimba (monga chitsulo) kuti mumenye pansi.
3. Chitsulo chotsalira pansi pa crucible chikuwonjezeka kutentha.
4. Zinthu zolimba zimakhudza mkati mwa crucible, monga kuponya zinthu zoponyera mu crucible.

Mng'alu wodutsa womwe uli pafupi theka la Metal Casting Crucible:Mng'alu uwu ukhoza kuwoneka pakati pa Ng'anjo yamoto, ndipo zifukwa zingaphatikizepo:

1. Ikani crucible pa maziko osayenera.
2. Gwiritsani ntchito pliers ya Smelting Crucibles kuti muchepetse malowo ndikugwiritsa ntchito mphamvu mopitilira muyeso.
3. Kuwongolera kolakwika kwa chowotcha kunapangitsa kutenthedwa kwa crucible ndi kutentha kosagwira ntchito kwa mbali zina, zomwe zimapangitsa kupsinjika kwa kutentha.

Mukamagwiritsa ntchito kupendekera (ndi nozzle)Zithunzi za Clay Graphite Crucibles, pangakhale ming'alu yopingasa m'munsi mwa mphuno ya crucible.Mng'alu uwu ukhoza kuyambitsidwa ndi kuyika kolakwika kwa crucible, ndipo dothi losasunthika limatha kufinyidwa pansi pa crucible nozzle pakuyika crucible yatsopano.

 

Vuto la mng'alu wautali

Chophimba chomwe chinagwiritsidwa ntchito koyamba chimakhala ndi ming'alu yayitali yomwe imadutsa pansi pa Sic Crucibles m'mphepete mwamunsi: izi zitha kuchitika chifukwa choyika crucible yoziziritsa pamoto wotentha kwambiri kapena kutenthetsa pansi mwachangu kwambiri pomwe crucible ikuzizira. Kupanikizika kwamafuta kumayambitsa ming'alu pansi pa crucible, nthawi zambiri imatsagana ndi zochitika monga glaze peeling.

Pambuyo pakugwiritsa ntchito nthawi yayitali pakhoma, ming'alu yakutali imawonekera pakhoma, ndipo khoma la crucible pamalo otsetsereka ndi locheperako:izi zikhoza kukhala chifukwa cha crucible ikuyandikira kapena kufika pa moyo wake wautumiki, ndipo khoma la crucible limakhala lochepa kwambiri, silingathe kupirira kupanikizika kwambiri.

Mng'alu umodzi wotalika kuchokera pamwamba pa crucible: Izi zikhoza kukhala chifukwa cha kutentha kwambiri kwa crucible, makamaka pamene kutentha kwapansi pansi ndi pansi pamphepete mwa crucible kumakhala mofulumira kuposa pamwamba. Zithanso kuyambitsidwa ndi zopinga zosayenera kapena kukhudzidwa kwa kudya kwa ingot m'mphepete mwapamwamba.

Ming'alu yofanana yotalikirana yoyambira pamwamba pa ma crucible angapo:Izi zikhoza kukhala chifukwa cha ng'anjo chivundikiro mwachindunji kukanikiza pa crucible, kapena kusiyana pakati pa ng'anjo chivundikirocho ndi crucible kukhala lalikulu kwambiri, kupanga crucible sachedwa makutidwe ndi okosijeni ndi kumabweretsa ming'alu.

Kuphulika kwautali kumbali ya crucible:nthawi zambiri amayamba chifukwa cha kupsyinjika kwamkati, monga kuyika zinthu zotayidwa zoziziritsidwa ngati mphero mopingasa mu crucible, zomwe zimatha kuwononga ngati zitenthedwa ndikukulitsa.

Lumikizanani nafe kuti tikupatseni fomu yowunikira zambiri za crucible failure

Mavuto omwe anthu ambiri amakumana nawo komanso kusanthula kwa ma crucibles awa amachokera kuzaka makumi angapo za kafukufuku ndi zochitika zopanga, kuyembekezera kuthandiza makasitomala kumvetsetsa bwino mavuto omwe angakumane nawo pogwiritsira ntchito ma crucibles ndikuchita zoyenera kuthetsa mavutowa. Pakupanga ndi kugwiritsa ntchito crucibles, ntchito zabwino komanso zogulitsa pambuyo pake ndizofunikira kuti zitsimikizire zokonda ndi kudalira kwa makasitomala.
