Kachulukidwe wapamwamba wosungunuka wa aluminiyumu dongo graphite crucible kwa induction ng'anjo

Mau oyamba: Ma graphite crucibles amatha kugawidwa m'magulu anayi.
1.Pure graphite crucible.Mpweya wa carbon nthawi zambiri umaposa 99.9%, ndipo umapangidwa ndi zinthu zopangira graphite.Zimangolimbikitsidwa kugwiritsa ntchito mitundu ina ya ng'anjo mosamala pang'anjo zamagetsi.

2.Clay graphite crucible.Amapangidwa ndi ufa wachilengedwe wa graphite wosakanikirana ndi dongo ndi zinthu zina zosagwirizana ndi okosijeni, ndipo amapangidwa mozungulira.Ndi yoyenera kwa mafakitale omwe ali ndi ndalama zochepa zogwirira ntchito komanso otsika mtengo.
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.Oyenera kusungunula kutentha kwakukulu, kufunikira kotchuka.

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.Ndiwoyenera kwambiri aluminium ndi zinc 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 yamafuta, ng'anjo ya gasi, ng'anjo yolimbana ndi moto, ng'anjo yapakati pafupipafupi (chonde dziwani kuti kusungunuka kwa aluminiyamu sikuli kokwera), ng'anjo ya tinthu tachilengedwe, ndi zina. Zoyenera kusungunula mkuwa, golide, siliva, ndi zina zotero. , zinki, aluminiyamu, lead, iron iron ndi zitsulo zina zosakhala ndi chitsulo.Komanso asidi osalimba komanso mankhwala amphamvu a alkali okhala ndi madzi otsika, kukana kwa dzimbiri komanso kukana kutentha kwambiri.

Malangizo ogwiritsira ntchito graphite crucible (chonde werengani mosamala musanagwiritse ntchito):
1.The crucible imasungidwa pamalo opumira komanso owuma 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, ndipo chivundikiro cha ng'anjo sichiyenera kukanikizidwa pa thupi lowonongeka.

5. Pewani jekeseni wamoto wolunjika ku thupi lophwanyidwa pamene mukugwiritsa ntchito, ndipo ayenera kupopera kumunsi kwa crucible.

6. Powonjezera zinthu, ziyenera kuwonjezeredwa pang'onopang'ono, makamaka 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. Ndibwino kugwiritsa ntchito crucible mosalekeza, kuti mugwiritse ntchito bwino ntchito yake yapamwamba.

9. Panthawi ya smelting, kuchuluka kwa kulowetsedwa kwa wothandizira kuyenera kuyendetsedwa.Kugwiritsa ntchito kwambiri kudzachepetsa moyo wautumiki wa crucible.

10. Mukamagwiritsa ntchito crucible, tembenuzani crucible nthawi ndi nthawi kuti ikhale yotentha mofanana ndikuwonjezera ntchito.

11. Dinani pang'ono pochotsa slag ndi coke kuchokera mkati ndi kunja kwa makoma a crucible kuti mupewe kuwonongeka kwa crucible.

12. Kugwiritsa ntchito zosungunulira za graphite crucible:
1) Chisamaliro chiyenera kulipidwa powonjezera zosungunulira: zosungunulira ziyenera kuwonjezeredwa ku chitsulo chosungunula, ndipo ndizoletsedwa kuwonjezera zosungunulira mumphika wopanda kanthu kapena chitsulo chisanayambe kusungunuka: yambitsani chitsulo chosungunula mwamsanga mutangowonjezera chosungunuliracho. zitsulo.
2) Njira Yogwirizana:
a.Zosungunulira ndi ufa, unyinji, ndi zitsulo zosungunulira.
b, dzina lachidziwitso chochuluka limasungunuka pakati pa crucible ndi gawo limodzi mwa magawo atatu a malo pamwamba pamunsi.
c.Kuthamanga kwa ufa kuyenera kuwonjezeredwa kuti musagwirizane ndi khoma la crucible.d.Ndizoletsedwa kuti chiwombankhangacho chibalalike mu ng'anjo yosungunuka, mwinamwake chidzawononga khoma lakunja la crucible.
e, Ndalama zomwe zawonjezeredwa ndi ndalama zochepa zomwe wopanga anena.
f.Pambuyo poyenga ndi kusinthidwa kuwonjezeredwa, chitsulo chosungunuka chiyenera kugwiritsidwa ntchito mwamsanga.
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.
Kuwonongeka: Silagi yomata iyenera kutsukidwa tsiku lililonse kumapeto 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.
