Zojambula za graphitekukhala ndi matenthedwe abwino komanso kukana kutentha kwambiri. Pogwiritsa ntchito kutentha kwakukulu, coefficient yawo yowonjezera kutentha imakhala yaying'ono, ndipo imakhala ndi mphamvu yotsutsa kutentha ndi kuzizira mofulumira. Kukana kwamphamvu kwa dzimbiri kwa asidi ndi njira zamchere, zokhala ndi kukhazikika kwamankhwala.
Makhalidwe a zinthu za graphite crucible
1. Ndalama zochepa, ma graphite crucibles amagulidwa mozungulira 40% pansi kuposa ng'anjo zofanana.
2. Ogwiritsa ntchito safunikira kupanga ng'anjo yamoto, ndipo dipatimenti yathu yamalonda imapereka ndondomeko yokwanira yopangira ndi kupanga.
3. Kugwiritsa ntchito mphamvu zochepa, chifukwa cha mapangidwe oyenerera, mapangidwe apamwamba, zipangizo zamakono, ndi kuyesa mphamvu zogwiritsira ntchito ma graphite crucibles poyerekeza ndi ng'anjo zofanana za chitsanzo chomwecho.
4. Kuchepa kwa kuipitsa, monga mphamvu yaukhondo monga gasi kapena gasi wamadzimadzi atha kugwiritsidwa ntchito ngati mafuta, zomwe zimapangitsa kuti kuchepeko kuipitsidwe.
5. Kuchita bwino ndi kulamulira, malinga ngati valavu ikusinthidwa malinga ndi kutentha kwa ng'anjo.
6. Makhalidwe abwino ndi apamwamba, ndipo chifukwa cha ntchito yabwino ndi kulamulira, ndi malo abwino ogwirira ntchito, khalidwe la mankhwala limatsimikiziridwa.
7. Mphamvu zimakhala ndi ntchito zambiri, zomwe zingagwiritsidwe ntchito kwambiri pa gasi lachilengedwe, gasi wamalasha, gasi wamadzimadzi, mafuta olemera, dizilo, ndi zina zotero. Angagwiritsidwenso ntchito pa malasha ndi coke pambuyo pa kusintha kosavuta.
8.Mng'anjo ya graphite crucible ili ndi ntchito zosiyanasiyana za kutentha, zomwe zimatha kusungunuka, zotsekedwa, kapena zonse zingagwiritsidwe ntchito palimodzi.
Ntchito yaukadaulo ya graphite crucible:
1. Kutentha kwa ng'anjo 300-1000
2. Mphamvu yosungunuka ya crucible (yochokera ku aluminiyamu) imachokera ku 30kg mpaka 560kg.
3. Kupanga mafuta ndi kutentha: 8600 calories / m2 ya gasi wachilengedwe.
4. Mafuta ambiri a aluminiyamu yosungunuka: 0,1 gasi wachilengedwe pa kilogalamu ya aluminiyamu.
5. Nthawi yosungunuka: 35-150 mphindi.
Oyenera kusungunula zitsulo zosiyanasiyana zosakhala ndi chitsulo monga golide, siliva, mkuwa, aluminiyamu, lead, zinki, komanso chitsulo chapakati cha carbon ndi zitsulo zosiyanasiyana zosowa.
Kuchita kwathupi: kukana moto ≥ 16500C; Kuwoneka porosity ≤ 30%; Kuchuluka kwa voliyumu ≥ 1.7g/cm3; Kuphatikizika kwamphamvu ≥ 8.5MPa
Kupanga mankhwala: C: 20-45%; SIC: 1-40%; AL2O3: 2-20%; SIO2: 3-38%
Chidutswa chilichonse chimayimira 1 kilogalamu yamkuwa wosungunuka.
Cholinga cha graphite crucible:
Graphite crucible ndi chotengera chokanirira chopangidwa ndi graphite yachilengedwe ya flake, mwala wa sera, silicon carbide ndi zida zina zopangira, zomwe zimagwiritsidwa ntchito posungunula ndi kuponyera mkuwa, aluminium, zinki, lead, golide, siliva, ndi zitsulo zosiyanasiyana zosowa.
Malangizo ogwiritsira ntchito zinthu za crucible
1. Nambala yodziwika ya crucible ndi kuchuluka kwa mkuwa (#/kg)
2. Mitsuko ya graphite iyenera kusungidwa kutali ndi chinyezi ndipo iyenera kusungidwa pamalo ouma kapena pamtengo.
3. Gwirani mosamala pamayendedwe ndikuletsa mwamphamvu kugwa kapena kugwedezeka.
4. Musanagwiritse ntchito, ndikofunikira kutenthetsa muzowumitsira zida kapena ndi ng'anjo, ndikutentha pang'onopang'ono mpaka 500 ℃.
5. Chophimbacho chiyenera kuikidwa pansi pa kamwa la ng'anjo kuti zisawonongeke pa chivundikiro cha ng'anjo.
6. Powonjezera zipangizo, ziyenera kukhazikitsidwa ndi kusungunuka kwa crucible, ndipo zinthu zambiri siziyenera kuwonjezeredwa kuti zipewe kufalikira kwa crucible.
7. Chida chotulutsira ndi crucible clamp chiyenera kugwirizana ndi mawonekedwe a crucible, ndipo gawo lapakati liyenera kumangirizidwa kuti lisawononge mphamvu ya m'deralo ku crucible.
8. Pochotsa slag ndi coke kuchokera mkati ndi kunja kwa makoma a crucible, ayenera kugogoda mofatsa kuti asawononge crucible.
9. Mtunda woyenera uyenera kusungidwa pakati pa crucible ndi khoma la ng'anjo, ndipo crucible iyenera kuikidwa pakati pa ng'anjo.
10. Kugwiritsa ntchito zida zoyaka kwambiri ndi zowonjezera zidzachepetsa moyo wautumiki wa crucible.
11. Pakugwiritsa ntchito, kutembenuza crucible kamodzi pa sabata kumatha kukulitsa moyo wake wautumiki.
12. Pewani kupopera mbewu mankhwalawa mwachindunji ndi malawi amphamvu a okosijeni m'mbali ndi pansi pa crucible.
