4. Qw ua kom huv si, raws li cov pa huv xws li cov nkev lossis roj li dej?
5. Kev ua haujlwm yooj yim thiab tswj, ntev npaum li lub valve raug hloov kho raws li lub cub hluavtaws kub.
6. Cov khoom lag luam zoo yog siab, thiab vim muaj kev ua haujlwm yooj yim thiab tswj, thiab kev ua haujlwm zoo, cov khoom lag luam zoo tau lees.
7. Zog muaj ntau cov kev siv, uas tuaj yeem siv tau siv dav rau cov roj ntuj, roj ntsha, roj ntsha, thiab lwm yam ntxiv tom qab kev hloov pauv yooj yim.
8.Qhov graphite crucle cub tau muaj ntau cov kev siv kub, uas tuaj yeem yaj, insulated, lossis ob leeg tuaj yeem siv ua ke.
Kev ua tau zoo ntawm graphite crucible:
1. Cov cua sov kub ntau yam 300-1000
2. Lub peev xwm melting ntawm tus ntoo khaub zig crucible (raws li txhuas) ib txwm los ntawm 30kg mus rau 560KG.
3. Roj thiab cov khoom siv hluav taws xob kub: 8600 calories / m ntawm nkev.
4. Kev siv roj loj rau cov leeg txhuas: 0.1 ntuj muaj roj ib phaus txhuas txhuas.
5. Melting sijhawm: 35-150 feeb.
Haum rau smelting ntau yam uas tsis muaj hlau xws li kub, tooj, txhuas, zas txhuas, nrog rau cov hlau roj carbon thiab ntau yam tsawg.
Kev ua yeeb yam ntawm lub cev: Hluav taws kub tiv taus ≥ 16500C; Pom tseeb pority ≤ 30%; Ntim ntom ntom ≥ 1.7G / CM3; Lub Zog Compression ≥ 8.5MPA
Kev siv tshuaj lom neeg: C: 20-45%; Siic: 1-40%; AL2O3: 2-20%; Sio2: 3-38%
Txhua tus crucible sawv cev 1 kilogram ntawm Molten tooj dag.
Lub hom phiaj ntawm graphite crucible:
Graphite crucible yog lub nkoj refaction ua los ntawm ntuj ci ntsej muag, siv hlau, siv rau tooj liab,, zinc, kub, nyiaj, thiab ntau yam hlau.
Cov lus qhia rau cov khoom crucible
1. Qhov tshwj xeeb tus naj npawb ntawm Crucible yog lub peev xwm ntawm tooj liab (# / kg)
2. Graphite crucibles yuav tsum tau ceev tseg deb ntawm ya raws thiab yuav tsum tau khaws cia rau hauv qhov chaw qhuav lossis ntawm daim duab ntoo.
3. Lis nrog saib xyuas nrog kev saib xyuas thaum lub sijhawm thauj mus los thiab nruj me ntsis tsis poob lossis tshee.
4. Ua ntej siv, nws yog qhov tsim nyog yuav tau kub hauv cov khoom qhuav lossis los ntawm lub cub tawg, nrog qhov kub maj mam nce mus rau 500 ℃.
5. Tus crucule yuav tsum muab tso rau hauv qab saum npoo ntawm cov cub tawg kom tsis txhob hnav thiab kua muag ntawm lub cub tawg.
6. Thaum cov ntaub ntawv ntxiv, nws yuav tsum tau ua raws li cov sububility ntawm crucible, thiab ntau cov khoom siv yuav tsum tsis txhob muab ntxiv kom tsis txhob nthuav ntawm tus ntoo khaub zig.
7. Cov cuab yeej tawm tawm thiab crucible clamp yuav tsum ua raws li cov duab ntawm Crucible, thiab nruab nrab feem yuav tsum tsis txhob muaj kev puas tsuaj hauv lub zog rau tus crucible.
8. Thaum tshem tawm cov nplais thiab coke ntawm sab hauv thiab sab nraud phab ntsa ntawm crucible, nws yuav tsum tau maj mam muab knocked kom tsis txhob ua kom tsis txhob ua rau tus ntoo khaub lig.
9. Qhov kev ncua deb yuav tsum tau tswj hwm ntawm tus crucible thiab lub rauv phab ntsa, thiab cov crucule yuav tsum muab tso rau hauv nruab nrab ntawm lub cub tawg.
10. Kev siv ntawm kev sib txuam ntau dhau thiab ntxiv yuav txo cov kev pabcuam lub neej ntawm Crucible.
11. Lub sijhawm siv, tig tus crucible ib zaug ib lub lim tiam tuaj yeem txuas nws lub neej ua haujlwm txuas ntxiv.
12. Zam kev txau ua kom muaj zog ntawm cov muaj zog oxidation nplaim taws hauv ob sab thiab hauv qab ntawm crucible.
