Graphite cruciblesvane yakanaka thermal conductivity uye yakakwirira tembiricha kuramba. Panguva yekushandiswa kwepamusoro-tembiricha, coefficient yavo yekuwedzera kwemafuta idiki, uye vane kumwe kuomarara kwekupisa nekutonhora nekukurumidza. Yakasimba corrosion kuramba kune acid uye alkaline mhinduro, ine yakanakisa kugadzikana kwemakemikari.
Hunhu hwe graphite crucible zvigadzirwa
1. Kudyara kwakaderera, graphite crucibles inotengeswa yakapoteredza 40% yakaderera pane mavira akafanana.
2. Vashandi havadi kugadzira choto che crucible, uye dhipatimendi redu rebhizimisi rinopa seti yakakwana yekugadzira nekugadzira.
3. Kuderera kwesimba rekushandisa, nekuda kwekugadzirwa kwakakodzera, chimiro chepamusoro, zvinyorwa zvitsva, uye kuedza kushandiswa kwesimba kwegirafu crucibles zvichienzaniswa nemavheni akafanana emuenzaniso wakafanana.
4. Kusvibiswa kushoma, sesimba rakachena rakadai segasi rechisikigo kana liquefied gasi rinogona kushandiswa sehuni, zvichikonzera kusvibiswa kushoma.
5. Kushanda kwakanaka uye kutonga, chero bedzi valve ichigadziriswa maererano nekupisa kwechoto.
6. Hunhu hwechigadzirwa hwakakwirira, uye nekuda kwekushanda nyore uye kutonga, uye nzvimbo yakanaka yekushanda, hutano hwechigadzirwa hunovimbiswa.
7. Simba rine maitiro akasiyana-siyana, anogona kushandiswa zvakanyanya kune gasi rechisikigo, gasi remarasha, liquefied gas, mafuta anorema, dizeli, etc. Inogonawo kushandiswa kwemarasha uye coke mushure mekushandura nyore.
8.The graphite crucible furnace ine huwandu hwakawanda hwekushanda kwekushisa, iyo inogona kunyungudutswa, insulated, kana zvose zvinogona kushandiswa pamwe chete.
Kuitwa kwehunyanzvi hwe graphite crucible:
1. Furnace tembiricha siyana 300-1000
2. Kunyunguduka kweiyo crucible (yakavakirwa paaluminium) inotangira kubva ku30kg kusvika ku560kg.
3. Kuberekwa kwemafuta uye kupisa: 8600 makorikori / m yegasi rechisikigo.
4. Kushandiswa kwemafuta kukuru kwealuminium yakanyungudutswa: 0.1 gasi rechisikiro pakirogiramu yealuminium.
5. Nguva yekunyunguduka: 35-150 maminitsi.
Inokodzera kunyungudutsa simbi dzakasiyana-siyana dzisina-ferrous dzakadai segoridhe, sirivheri, mhangura, aruminiyamu, lead, zingi, pamwe nepakati kabhoni simbi uye dzakasiyana siyana zvisingawanzo simbi.
Kuita kwemuviri: Kuramba kwemoto ≥ 16500C; Inooneka porosity ≤ 30%; Kuwanda kwehuwandu ≥ 1.7g/cm3; Kudzvinyirira simba ≥ 8.5MPa
Kuumbwa kwemakemikari: C: 20-45%; SIC: 1-40%; AL2O3: 2-20%; SIO2: 3-38%
Imwe neimwe crucible inomiririra 1 kilogiramu yendarira yakanyungudutswa.
Chinangwa che graphite crucible:
Graphite crucible imudziyo unorambira wakagadzirwa neakasikwa flake graphite, wakisi dombo, silicon carbide uye zvimwe zvigadzirwa, zvinoshandiswa kunyungudutsa nekukanda mhangura, aruminiyamu, zingi, lead, goridhe, sirivheri, uye akasiyana simbi asingawanzo.
Mirayiridzo yekushandisa zvigadzirwa zvecrucible
1. Nhamba yezvinyorwa zve crucible ndiko kukwanisa kwemhangura (#/kg)
2. Graphite crucibles inofanira kuchengetwa kure nehunyoro uye inofanira kuchengetwa munzvimbo yakaoma kana pamapuranga emapuranga.
3. Bata nekungwarira panguva yekufambisa uye nyatso rambidza kudonha kana kuzununguka.
4. Usati washandisa, zvakakosha kupisa kubika mumichina yekuomesa kana nechoto, nekushisa zvishoma nezvishoma kukwira kusvika ku500 ℃.
5. Iyo crucible inofanira kuiswa pasi pepamusoro pemuromo wechoto kuti usasakara uye kubvarura pachifukidziro chevira.
6. Paunenge uchiwedzera zvinhu, zvinofanira kunge zvichibva pakunyunguduka kwechikafu, uye zvinhu zvakawandisa hazvifaniri kuwedzerwa kuti zvidzivirire kuwedzera kwe crucible.
7. Chishandiso chekuburitsa uye crucible clamp inofanirwa kuenderana nechimiro cheiyo crucible, uye chikamu chepakati chinofanira kusungirirwa kuti chidzivise kukuvara kwesimba renzvimbo kune crucible.
8. Paunenge uchibvisa slag uye coke kubva mukati uye kunze kwemadziro emukati, inofanira kugogodzwa zvinyoronyoro kuti irege kukuvadza crucible.
9. Chinhambwe chakakodzera chinofanira kuchengetedzwa pakati pe crucible uye rusvingo rwevira, uye crucible inofanira kuiswa pakati pechoto.
10. Kushandiswa kwezvibatsiro zvinopisa zvakanyanya uye zvinowedzera zvinoderedza hupenyu hwebasa re crucible.
11. Panguva yekushandiswa, kutenderedza crucible kamwe pavhiki kunogona kuwedzera hupenyu hwayo hwebasa.
12. Dzivisa kupfapfaidza kwakananga kwemirazvo yakasimba oxidation pamativi uye pasi pe crucible.
