Kev Taw Qhia: Graphite crucibles tuaj yeem muab faib ua plaub pawg.
1. Lub crucible graphite ntshiab.cov ntsiab lus carbonfeem ntau yog loj dua99.9%, thiab nws yog ua los ntawm cov khoom siv graphite dawb huv. Nws tsuas yog pom zoo kom siv lwm hom cub tawg kom zoo zoo raucov cub hluav taws xob.
2. Av nplaum graphite crucible. Nws yog ua los ntawm cov hmoov graphite ntuj sib xyaw nrog av nplaum thiab lwm yam khoom siv tiv taus oxidation, thiab yog rotationally tsim. Nws yog tsim rau cov chaw tsim khoom nrog ltus nqi ua haujlwmthiabkev ua haujlwm qis.
3. Lub pob zeb silicon carbide graphite crucible, ua los ntawm cov hmoov graphite ntuj, silicon carbide, aluminium oxide, thiab lwm yam sib xyaw ua cov khoom siv raw, tig-molded, thiab ntxiv nrog ib txheej tiv thaiv oxidation. Lub neej ua haujlwm yog li 3-8 npaug ntawm cov av nplaum graphite crucible. Qhov ceev ntawm cov khoom yog ntawm 1.78-1.9. Haum raukev sim kub siab smelting, kev thov nrov.
4. Lub silicon carbide graphite crucible yog tsim los ntawm isostatic pressing, thiab lub crucible yog nias los ntawm lub tshuab isostatic pressing. Lub neej ua haujlwm feem ntau yog 2-4 npaug ntawm cov rotary tsim silicon carbide graphite crucible. Nws yog qhov tsim nyog tshaj plaws rautxhuasthiabzinc oxide. Lwm cov hlau yuav tsum tau xaiv kom zoo, thiab cov cub tawg induction yuav tsum tau xaiv kom zoo. Vim yog tus nqi siab ntawm isostatic pressing, feem ntau tsis muaj crucible me me.

Cov hom cub tawg rau crucibles:lub cub tawg coke, roj cub tawg, lub cub tawg roj av, cua sov tiv taus, nruab nrab zaus induction cub tawg(thov nco ntsoov tias qhov ua tau zoo ntawm txhuas yaj tsis siab), lub cub tawg me me, thiab lwm yam. Haum rau kev smelting tooj liab, kub, nyiaj, zinc, txhuas, txhuas, txhuas, hlau cam khwb cia thiab lwm yam hlau uas tsis yog ferrous. Ib yam li cov tshuaj lom neeg uas tsis muaj zog thiab cov tshuaj alkali muaj zog nrogtsis tshua muaj dej ntws, kev tiv thaiv xebthiabkub siab ua haujlwm.
Cov lus qhia rau kev siv graphite crucible (thov nyeem kom zoo ua ntej siv):
1. Lub crucible khaws cia rau hauv ib qhocua nkag tauthiabqhuavib puag ncig kom tsis txhob raug cuam tshuam los ntawm cov dej noo.
2. Lub crucible yuav tsum tau ua tib zoo tuav, nws yog txwv tsis pub poob thiab co, thiab tsis txhob dov, yog li ntawd kom tsis txhob ua puas rau txheej tiv thaiv ntawm qhov chaw ntawm lub crucible.
3. Ci lub crucible ua ntej siv. Qhov kub ntawm kev ci maj mam nce ntawm qis mus rau siab, thiab lub crucible tas li tig kom nws sov sib npaug, tshem tawm cov dej noo hauv lub crucible, thiab maj mam nce qhov kub ua ntej kom ntau dua 500 (xws li preheating). Tsis raug, ua rau lub crucible tev tawm thiab tawg, nws tsis yog teeb meem zoo thiab yuav tsis rov qab los)
4. Lub cub tawg crucible yuav tsum tau phim nrog lub crucible, qhov sib txawv sab saud thiab sab qis thiab ib puag ncig yuav tsum ua tau raws li qhov yuav tsum tau ua, thiablub hau cub tawg yuav tsum tsis txhob nias rau ntawm lub cev crucible.
5. Tsis txhob muab hluav taws kub ncaj qha rau lub cev crucible thaum siv, thiab yuav tsum tau uatxau mus rau lub hauv paus crucible.
6. Thaum ntxiv cov khoom, nws yuav tsum tau ntxiv qeeb qeeb, zoo duacov khoom tawgTsis txhob ntim cov khoom aniseed ntau dhau los yog nruj dhau, kom tsis txhob tawg lub crucible.
7. Cov crucible tongs siv rau kev thauj khoom thiab unloading yuav tsum sib xws nrog cov duab ntawm lub crucible, yog li ntawd kom tsis txhob ua puas lub crucible.
8. Nws yog qhov zoo tshaj plaws rausiv lub crucible tas li, yog li ntawd kom zoo dua nws qhov kev ua tau zoo.
9. Thaum lub sijhawm ua cov txheej txheem smelting, cov nyiaj nkag ntawmtus neeg sawv cev yuav tsum tau tswj hwmSiv ntau dhau yuav txo lub neej ua haujlwm ntawm lub crucible.
10. Thaum siv lub crucible,tig lub crucible ib ntusua kom nws sov sib npaug thiab siv tau ntev.
11.Coj mus rhaub maj mamthaum tshem cov slag thiab coke ntawm sab hauv thiab sab nraud phab ntsa ntawm lub crucible kom tsis txhob muaj kev puas tsuaj rau lub crucible.
12. Siv cov kuab tshuaj rau graphite crucible:
1) Yuav tsum tau saib xyuas thaum ntxiv cov kuab tshuaj:cov tshuaj yaj yuav tsum tau ntxiv rau cov hlau molten, thiab nws yog txwv tsis pub ntxiv cov tshuaj yaj rau hauv lub lauj kaub khoob lossis ua ntej cov hlau yaj: do cov hlau yaj tam sim ntawd tom qab ntxiv cov hlau yaj.
2) Txoj kev koom ua ke:
a. Cov kuab tshuaj yog hmoov, cov khoom loj, thiab cov hlau sib xyaw.
b, lub npe ntawm daim ntawv thov loj yog yajmus rau hauv nruab nrab ntawm lub cruciblethiabib feem peb ntawm qhov chaw saum toj ntawm qhov chaw hauv qab.
c. Cov hmoov av yuav tsum tau ntxiv rautsis txhob kov ncaj qha rau ntawm phab ntsa crucible. d. Nws yogtxwv tsis pub cov flux tawg rau hauv lub cub tawg, lwm yam liyuav ua rau phab ntsa sab nraud puas tsuajntawm lub crucible.
e, Tus nqi ntxiv yogtus nqi tsawg kawg nkausteev los ntawm tus neeg tsim khoom.
f. Tom qab ntxiv cov neeg ua kom huv thiab cov khoom hloov kho, cov hlau uas yaj lawmyuav tsum tau siv sai sai.
g, paub tseeb tias siv cov flux kom raug. Kev yaig ntawm cov flux ntawm graphite crucible Refining modifier erosion: Cov fluoride hauv cov refining modifier yuav yaig cov crucible los ntawm qhov qis dua (R) ntawm phab ntsa sab nraud ntawm cov crucible.
Corrosion: Cov slag nplaum crucible yuav tsum tau nplaumntxuav txhua hnubthaum kawg ntawm qhov hloov pauv. Qhov kev puas tsuaj uas tsis tau ua haujlwm yuav raug muab tso rau hauv cov slag thiab kis mus rau hauv lub crucible, ua rau muaj kev pheej hmoo ntawm kev puas tsuaj thiab kev puas tsuaj. Kub thiab qhov nrawm ntawm kev xeb: Qhov nrawm ntawm kev ua haujlwm ntawm lub crucible thiab tus neeg sawv cev ua kom huv yog sib npaug rau qhov kub. Kev nce qhov kub siab tsis tsim nyog ntawm cov kua hlau yuav ua rau lub neej ntawm lub crucible luv luv heev. Kev xeb ntawm cov tshauv txhuas thiab cov slag txhuas: Rau cov tshauv txhuas uas muaj cov ntsev sodium loj thiab cov ntsev phosphorus, qhov xwm txheej xeb yog tib yam li saum toj no, uas yuav ua rau lub neej ntawm lub crucible luv luv heev. Kev puas tsuaj ntawm cov khoom hloov kho nrog cov kua zoo: Thaum cov khoom hloov kho nrog cov kua zoo ntxiv, cov hlau yaj yuav tsum tau do sai sai kom nws tsis tuaj yeem sib cuag nrog lub cev lauj kaub.
13. Cov Cuab Yeej Siv Los Ntxuav Cov Graphite Crucible Slag: Cov cuab yeej no puag ncig nrog qhov nkhaus zoo ib yam li phab ntsa sab hauv ntawm lub lauj kaub siv. Kev tshem tawm thawj zaug: Tom qab ua kom sov thiab siv thawj zaug, kev tshem tawm cov slag tsim tawm yog qhov tseem ceeb tshaj plaws. Cov slag tsim tawm thawj zaug yog mos heev, tab sis tom qab nws tawm mus, nws nyuaj heev thiab nyuaj rau tshem tawm. Lub Sijhawm Ntxuav:Txawm hais tias lub crucible tseem kub thiab cov slag mos, nws yuav tsum tau purged txhua hnub.
