Taw qhia: Graphite crucibles tuaj yeem muab faib ua plaub pawg.
1.Ntshiab graphite crucible.Cov ntsiab lus carbon feem ntau yog ntau dua 99.9%, thiab nws yog ua los ntawm cov khoom siv graphite ntshiab.Nws tsuas yog pom zoo kom siv lwm hom rauv ua tib zoo rau lub tshuab hluav taws xob.
2.Clay graphite crucible.Nws yog ua los ntawm ntuj graphite hmoov tov nrog av nplaum thiab lwm yam ntaub ntawv oxidation-resistant, thiab yog rotationally tsim.Nws yog tsim rau cov chaw tsim khoom nrog tus nqi qis zog thiab kev ua haujlwm qis.
3.Silicon carbide graphite crucible, rotationally tsim.Nws yog tsim los ntawm ntuj graphite hmoov, silicon carbide, aluminium oxide, thiab lwm yam sib xyaw ua raw cov ntaub ntawv, spin-molded, thiab ntxiv nrog cov txheej txheem oxidation.Lub neej kev pabcuam yog li 3-8 npaug ntawm cov av nplaum graphite crucible.Qhov ntom ntom ntom ntom ntom yog nyob nruab nrab ntawm 1.78-1.9.Haum rau kev ntsuas kub kub smelting, nrov thov.
4.Lub silicon carbide graphite crucible yog tsim los ntawm isostatic nias, thiab lub crucible yog nias los ntawm ib tug isostatic pressing tshuab.Lub neej kev pab cuam feem ntau yog 2-4 npaug ntawm cov teb tsim silicon carbide graphite crucible.Nws yog qhov tsim nyog tshaj plaws rau txhuas thiab zinc oxide.Lwm cov hlau yuav tsum tau ua tib zoo xaiv, thiab cov cua sov induction yuav tsum tau xaiv kom zoo.Vim yog tus nqi siab ntawm isostatic nias, feem ntau tsis muaj me me crucible.

Rauv hom rau crucibles: coke rauv, roj rauv, natural gas furnace, kuj rauv, nruab nrab zaus induction rauv (thov nco ntsoov tias lub melting efficiency ntawm txhuas tsis siab), lom particle rauv, thiab lwm yam. Haum rau smelting tooj liab, kub, nyiaj. , zinc, aluminium, lead, cam khwb cia hlau thiab lwm yam hlau tsis-ferrous.Raws li tsis muaj zog acid thiab muaj zog alkali tshuaj nrog tsawg fluidity, corrosion kuj thiab kub tsis kam.
Cov lus qhia rau kev siv graphite crucible (thov ua tib zoo nyeem ua ntej siv):
1.Lub crucible khaws cia rau hauv qhov chaw cua thiab qhuav kom tsis txhob raug cuam tshuam los ntawm noo noo.
2. Lub crucible yuav tsum tau ua tib zoo saib xyuas, nws yog nruj me ntsis txwv tsis pub poob thiab co, thiab tsis txhob dov, thiaj li tsis ua kom puas cov txheej tiv thaiv nyob rau saum npoo ntawm crucible.
3. Ci lub crucible ua ntej siv.Lub ci kub yog maj mam nce los ntawm qis mus rau siab, thiab lub crucible yog tas li tig kom nws yuav tsum tau rhuab tusyees, tshem tawm cov ya raws nyob rau hauv lub crucible, thiab maj mam nce lub preheating kub rau ntau tshaj 500 (xws li preheating).Tsis tsim nyog, ua rau lub crucible tev tawm thiab tawg, nws tsis yog qhov teeb meem zoo thiab yuav tsis rov qab)
4. Lub qhov cub tawg yuav tsum sib phim nrog lub crucible, lub sab sauv thiab sab qis thiab ib puag ncig qhov khoob yuav tsum ua tau raws li qhov yuav tsum tau ua, thiab lub qhov cub npog yuav tsum tsis txhob nias rau ntawm lub cev crucible.
5. Tsis txhob siv cov nplaim hluav taws ncaj qha mus rau lub cev crucible thaum siv, thiab yuav tsum tau txau ntawm lub hauv paus crucible.
6. Thaum ntxiv cov khoom, nws yuav tsum tau ntxiv maj mam, nyiam dua crushed khoom.Tsis txhob ntim ntau dhau los yog nruj ntawm cov khoom siv aniseed, thiaj li tsis txhob tawg lub crucible.
7. Lub crucible tongs siv rau loading thiab unloading yuav tsum ua raws li cov duab ntawm lub crucible, thiaj li tsis mus ua puas lub crucible.
8. Nws yog qhov zoo tshaj plaws los siv lub crucible tsis tu ncua, kom ua tau zoo dua nws cov kev ua haujlwm siab.
9. Thaum lub sij hawm smelting txheej txheem, cov input tus neeg sawv cev yuav tsum tau tswj.Kev siv ntau dhau yuav txo qhov kev pab cuam lub neej ntawm lub crucible.
10. Thaum siv lub crucible, tig lub crucible ib ntus kom nws cov cua sov sib npaug thiab siv sijhawm ntev.
11. Coj mus rhaub maj mam thaum tshem tawm slag thiab coke los ntawm cov phab ntsa sab hauv thiab sab nrauv ntawm lub crucible kom tsis txhob muaj kev puas tsuaj rau lub crucible.
12. Siv cov kuab tshuaj rau graphite crucible:
1) Kev ceev faj yuav tsum tau them thaum ntxiv cov kuab tshuaj: cov kuab tshuaj yuav tsum tau ntxiv rau cov hlau molten, thiab nws yog nruj me ntsis txwv tsis pub ntxiv cov hnyav rau lub lauj kaub khoob lossis ua ntej cov hlau yaj: do cov hlau molten tam sim ntawd tom qab ntxiv cov molten. hlau.
2) Koom nrog txoj kev:
ib.Cov kuab tshuaj yog hmoov, bulk, thiab hlau alloys.
b, daim ntawv thov ntau lub npe yog melted rau hauv nruab nrab ntawm lub crucible thiab ib feem peb ntawm txoj hauj lwm saum toj no hauv qab.
c.Cov hmoov flux yuav tsum tau ntxiv kom tsis txhob muaj kev sib cuag ncaj qha nrog cov phab ntsa crucible.d.Nws yog nruj me ntsis txwv tsis pub cov flux yuav tawg nyob rau hauv lub melting rauv, txwv tsis pub nws yuav corrode sab nrauv phab ntsa ntawm lub crucible.
e, Tus nqi ntxiv yog qhov tsawg kawg nkaus uas tau teev tseg los ntawm cov chaw tsim khoom.
f.Tom qab tus neeg sawv cev refining thiab hloov kho ntxiv, cov hlau molten yuav tsum tau thov sai sai.
g, paub meej tias qhov tseeb flux yog siv.Flux erosion ntawm graphite crucible Refining modifier erosion: Cov fluoride nyob rau hauv refining modifier yuav erode lub crucible los ntawm sab qis (R) ntawm sab nrauv phab ntsa ntawm lub crucible.
Corrosion: Lub crucible nplaum slag yuav tsum tau ntxuav txhua hnub thaum kawg ntawm kev ua haujlwm.Unreacted deterioration yuav immersed nyob rau hauv lub slag thiab diffuse mus rau hauv lub crucible, ua rau muaj kev pheej hmoo ntawm refining deterioration thiab yaig.Kub thiab corrosion tus nqi: Cov tshuaj tiv thaiv tus nqi ntawm lub crucible thiab cov refining tus neeg sawv cev yog proportional rau qhov kub thiab txias.Ua kom qhov kub tsis tseem ceeb ntawm cov kua alloy yuav ua rau lub neej ntawm lub crucible luv luv.Corrosion ntawm txhuas tshauv thiab txhuas slag: Rau txhuas tshauv uas muaj ntsev ntsev thiab phosphorus ntsev, qhov corrosion kuj zoo ib yam li cov saum toj no, uas yuav luv luv lub neej ntawm crucible.Erosion ntawm lub modifier nrog zoo fluidity: Thaum lub modifier nrog zoo fluidity yog ntxiv, molten hlau yuav tsum tau stirred sai sai kom nws tsis tuaj yeem tiv tauj nrog lub lauj kaub lub cev.
13. Graphite Crucible Slag Cleaning Tool: Cov cuab yeej yog sib npaug nrog cov curvature zoo ib yam li cov phab ntsa sab hauv ntawm lub lauj kaub siv.Kev tshem tawm thawj zaug: Tom qab thawj zaug cua sov thiab siv, kev tshem tawm ntawm cov slag tsim yog qhov tseem ceeb tshaj plaws.Lub slag tsim thawj zaug yog mos heev, tab sis tom qab nws tawm mus, nws yuav nyuaj heev thiab nyuaj rau tshem tawm.Purge Sijhawm: Thaum lub crucible tseem kub thiab lub slag yog mos, nws yuav tsum tau purged txhua hnub.
