Mau oyamba: Ma graphite crucibles amatha kugawidwa m'magulu anayi.
1.Pure graphite crucible.Thempweya wa carbonzambiri kuposa99.9%, ndipo amapangidwa ndi graphite yokhayokha.Zimangolimbikitsa kugwiritsa ntchito mitundu ina ya ng'anjo mosamalang'anjo zamagetsi.
2.Clay graphite crucible.Amapangidwa ndi ufa wachilengedwe wa graphite wosakanikirana ndi dongo ndi zinthu zina zosagwirizana ndi okosijeni, ndipo amapangidwa mozungulira.Ndizoyenera mafakitale okhala ndi lmtengo wantchitondiotsika mtengo ntchito.
3.Silicon carbide graphite crucible, yozungulira yopangidwa.Zimapangidwa ndi ufa wa graphite wachilengedwe, silicon carbide, aluminium oxide, ndi zina zotero.Moyo wautumiki ndi pafupifupi 3-8 nthawi ya dongo graphite crucible.Kuchulukana kwakukulu kuli pakati pa 1.78-1.9.Zoyeneramkulu kutentha mayeso smelting, zofuna zotchuka.
4.Silicon carbide graphite crucible imapangidwa ndi kuponderezedwa kwa isostatic, ndipo crucible imapanikizidwa ndi makina osindikizira a isostatic.Moyo wautumiki nthawi zambiri umakhala nthawi 2-4 kuposa wa rotary wopangidwa ndi silicon carbide graphite crucible.Ndizoyenera kwambirialuminiyamundizinc oxide.Zitsulo zina ziyenera kusankhidwa mosamala, ndipo ng'anjo za induction ziyenera kusankhidwa mosamala.Chifukwa cha kukwera mtengo kwa kukanikiza kwa isostatic, nthawi zambiri palibe crucible yaying'ono.

Mitundu ya ng'anjo ya crucibles:ng'anjo ya coke, ng'anjo ya mafuta, ng'anjo ya gasi, ng'anjo yotsutsa, ng'anjo yapakati pafupipafupi(chonde dziwani kuti kusungunuka kwa aluminiyamu sipamwamba), ng'anjo ya tizilombo toyambitsa matenda, etc. Yoyenera kusungunula mkuwa, golide, siliva, zinki, aluminiyamu, kutsogolera, chitsulo choponyedwa ndi zitsulo zina zopanda chitsulo.Komanso si amphamvu asidi ndi amphamvu alkali mankhwala ndiotsika fluidity, kukana dzimbirindikutentha kwambiri kukana.
Malangizo ogwiritsira ntchito graphite crucible (chonde werengani mosamala musanagwiritse ntchito):
1. The crucible imasungidwa mu ampweya wabwinondiyoumachilengedwe kuti asakhudzidwe ndi chinyezi.
2. Chophimbacho chiyenera kusamaliridwa mosamala, ndi choletsedwa kwambiri kugwetsa ndi kugwedeza, ndipo musagwedezeke, kuti musawononge chitetezo chotetezera pamwamba pa crucible.
3. Kuphika crucible pasadakhale musanagwiritse ntchito.Kutentha kwa kuphika kumawonjezeka pang'onopang'ono kuchokera kumunsi kupita kumtunda, ndipo crucible imatembenuzidwa nthawi zonse kuti itenthedwe mofanana, kuchotsa chinyezi mu crucible, ndikuwonjezera kutentha kwa preheating kupitirira 500 (monga preheating).Zosayenera, zomwe zimapangitsa kuti crucible iwonongeke ndikuphulika, si vuto labwino ndipo silidzabwezedwa)
4. Ng'anjo yowonongeka iyenera kugwirizanitsidwa ndi crucible, mipata yapamwamba ndi yapansi ndi yozungulira iyenera kukwaniritsa zofunikira, ndipong'anjo chophimba sayenera mbamuikha pa crucible thupi.
5. Pewani jekeseni wamoto wolunjika ku thupi la crucible panthawi yogwiritsira ntchito, ndipo ziyenera kukhalakupopera ku crucible base.
6. Powonjezera zinthu, ziyenera kuwonjezeredwa pang'onopang'ono, makamakazinthu zophwanyidwa.Osanyamula katundu wambiri kapena wothina kwambiri, kuti crucible isaphulike.
7. Nsalu zachitsulo zomwe zimagwiritsidwa ntchito ponyamula ndi kutulutsa ziyenera kukhala zogwirizana ndi mawonekedwe a crucible, kuti zisawonongeke.
8. Ndi bwino kutigwiritsani ntchito crucible mosalekeza, kuti azitha kuchita bwino kwambiri.
9. Pa smelting ndondomeko, athandizira kuchuluka kwawothandizira ayenera kulamulidwa.Kugwiritsa ntchito kwambiri kudzachepetsa moyo wautumiki wa crucible.
10. Mukamagwiritsa ntchito mphira,tembenuzani crucible nthawi ndi nthawikuti azitenthetsa mofanana ndikutalikitsa ntchito.
11.Dinani pang'onopochotsa slag ndi coke kuchokera mkati ndi kunja kwa makoma a crucible kupewa kuwonongeka kwa crucible.
12. Kugwiritsa ntchito zosungunulira za graphite crucible:
1) Chidwi chiyenera kulipidwa powonjezera zosungunulira:zosungunulira ziyenera kuwonjezeredwa ku chitsulo chosungunuka, ndipo ndizoletsedwa kwambiri kuwonjezera zosungunulira mumphika wopanda kanthu kapena chitsulo chisanasungunuke: gwedezani chitsulo chosungunuka mwamsanga mutatha kuwonjezera chitsulo chosungunuka.
2) Njira Yogwirizana:
a.Zosungunulira ndi ufa, unyinji, ndi zitsulo zosungunulira.
b, dzina lantchito yochuluka limasungunukam'katikati mwa mphirandigawo limodzi mwa magawo atatu a malo pamwamba pa nthaka pansi.
c.Kutuluka kwa ufa kuyenera kuwonjezeredwapewani kukhudzana mwachindunji ndi khoma la crucible.d.Zili chonchozoletsedwa mwamphamvu kuti chiwombankhangacho chibalalike mu ng'anjo yosungunuka, apo ayiadzawononga khoma lakunjawa crucible.
e, Ndalama zomwe zawonjezeredwa ndindalama zochepaofotokozedwa ndi wopanga.
f.Pambuyo poyenga ndi kusintha kwawonjezeredwa, chitsulo chosungunukaiyenera kugwiritsidwa ntchito mwachangu.
g, onetsetsani kuti kusinthasintha kolondola kumagwiritsidwa ntchito.Kukokoloka kwa Flux pa graphite crucible Kukokoloka kosintha kosintha: Fluoride mu chosinthira choyenga chidzakokolola crucible kuchokera kumunsi (R) kwa khoma lakunja la crucible.
Zidzimbiri: Silagi yomata iyenera kukhalakutsukidwa tsiku lililonsekumapeto kwa kusintha.Kuwonongeka kosasunthika kudzamizidwa mu slag ndikufalikira mu crucible, kuonjezera chiopsezo cha kukonzanso kuwonongeka ndi kukokoloka.Kutentha ndi dzimbiri mlingo: Mmene mlingo wa crucible ndi woyenga wothandizira ndi molingana ndi kutentha.Kuonjezera kutentha kosafunikira kwa madzi a alloy kudzafupikitsa kwambiri moyo wa crucible.Kuwonongeka kwa phulusa la aluminiyamu ndi phulusa la aluminiyamu: Kwa phulusa la aluminiyamu lomwe lili ndi mchere wambiri wa sodium ndi mchere wa phosphorous, momwe dzimbiri zimakhalira ndizofanana ndi zomwe tafotokozazi, zomwe zidzafupikitsa kwambiri moyo wa crucible.Kukokoloka kwa chosinthira ndi madzi abwino: Pamene chosinthira chokhala ndi madzi abwino chiwonjezedwa, chitsulo chosungunuka chiyenera kugwedezeka mofulumira kuti chitha kukhudzana ndi thupi la mphika.
13. Graphite Crucible Slag Cleaning Tool: Chidacho chimazunguliridwa ndi kupindika kofanana ndi khoma lamkati la mphika wogwiritsidwa ntchito.Kuchotsa koyamba: Pambuyo pakuwotcha koyamba ndikugwiritsa ntchito, kuchotsedwa kwa slag komwe kumapangidwa ndikofunikira kwambiri.Slag yopangidwa kwa nthawi yoyamba imakhala yofewa, koma ikasiyidwa, imakhala yovuta kwambiri komanso yovuta kuchotsa.Nthawi Yoyeretsa:Ngakhale crucible ikadali yotentha ndipo slag ndi yofewa, iyenera kutsukidwa tsiku ndi tsiku.
