Daim ntawv thov khoom

1. Graphite crucible tuaj yeem siv rau cov hlau tsis-ferrous smelting thiab casting, dissolving kub los yog nyiaj ornaments, tsom xam ntawm tshwj xeeb hom hlau, sintering nyuaj hlau.

2. Graphite crucible rau smelting kub yog tshwj xeeb hauv melting kub nyob rau hauv headgear thiab hniav nyiaj hniav kub industry. Qhov kev thov uas tau thov kom muaj qhov ntom qe muaj siab thiab muaj kev huv, ablation-tiv, thiab nws tuaj yeem siv ntau zaug. Peb tuaj yeem tshuab ntau yam crucibles raws li cov neeg siv khoom xav tau.

3. Machined los ntawm siab ntshiab graphite thiab dav siv nyob rau hauv kub, nyiaj, platinum thiab lwm yam noble hlau melting.Yog hais tias nws yog siv nyob rau hauv cov pa oxygen, nws yuav pib oxygenized thaum kub siab tshaj 700-800 degree c. Yog tias nws siv nyob rau hauv qhov chaw tiv thaiv, nws tuaj yeem sawv ntau tshaj 2000 degree c.

4. Dav siv nyob rau hauv xws li kev lag luam furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, roj, chemistry, textile, hluav taws xob machinery, hluav taws xob khoom, hluav taws xob rauv, tsheb, kev sib txuas lus kev lag luam , tshuaj, thiab lwm yam.

LUS QHIA RAU SIV

1. Kev npaj ua ntej kev teeb tsa

1) Txheeb xyuas tias cov phab ntsa sab hauv thiab hauv qab ntawm lub qhov cub hluav taws xob tsis zoo.

2) Xyuas seb puas muaj cov slag seem nyob rau hauv lub cub tawg, yog tias yog li tshem tawm nws raws sij hawm.

2. Xaiv lub corect crucible puag

1) Crucible puag yuav tsum zoo ib yam thiab loj me me (li 2cm) raws li hauv qab ntawm lubcrucible.

2) Rau ntau hom crucible fumaces, tsim nyog qhov siab crucible puag yuav tsum tau xaiv.

3) Tsis txhob siv cov khib nyiab, crucible puag, txwv tsis pub nws yuav luv luv lub neej crucible.

3. Kev teeb tsa thiab kho

Crucible rau roj los yog roj rauv installation:

Ua ntej lub crucible yog muab tso rau hauv lub hauv paus, thiab ib tug tej yam crucible expansion qhov chaw yog reserved ntawm lubcrucible thiab sab saum toj ntawm lub cub tawg phab ntsa uas yog tsau los ntawm kev siv ntoo blocks, cardboard thiab lwm yamcov ntaub ntawv.

Kho qhov chaw ntawm lub qhov cub thiab lub nozzle kom cov nplaim taws ua raws li qhov sib xyawchamber thiab tsis tuaj yeem ncaj qha mus rau hauv qab ntawm lub crucible.

4. Baking nkhaus daim duab ntawm graphite silicon carbide crucible

product-639-370

1) Yog tias tus neeg siv khoom tau nres lub qhov cub rau ntau tshaj 5 hnub, lub crucible yuav tsum tau ci dua li ib qho tshiabcrucible.

2) Vim tias cov khoom siv hauv lub tshuab ua kom sov lub cev muaj cov dej noo loj, lub tshuab hluav taws xob tshiab yuav tsum tau ci.rau ob xuab moos, thiab tom qab ntawd thauj mus rau hauv lub crucible, thiab ci lub cauldron thiab cub lub cev nrog ci tshiab.crucible.

3) Cracks tshwm nyob rau hauv lub crucible, them tshwj xeeb mloog ua ntej 200 degrees, . Tsis txhob maj. Qhov kub yog nceqeeb heev, kom lub crucible muaj cov txheej txheem adaptation. Yog tias lub crucible khaws cia rau lub sijhawm ntev, nws yog qhov yuav tsum tau uancua lub sij hawm qis-kub ci kom tshem tawm cov dej vapor tag.

4) Ua ntej nres lub cub tawg, rub tawm cov molten aluminium. Thiab ntxuav lub scum ntawm sab hauv phab ntsa ntawm lubcrucible thaum nws kub. Tiv thaiv lub crucible los ntawm kev kub siab dua. Lub dross tseem yuav corrode lub cruciblethiab cuam tshuam cov cua kub conduction, Kaw lub qhov cub thiab kaw lub qhov cua. kom tswj qhov kub ntawm qhov seem.

5) Thaum lub qhov cub kub tseem nyob hauv lub neej, thaum siv crucible dua, yog li xav tau raws li qhov qubpreheating hom. Thaum lub qhov cub kub tau rov qab thiab txias, thaum siv lub crucible dua, yog li xav tauraws li txoj kev preheating ntawm rov siv dua.

(一) Resistance furnace crucible ci

1) Vim tias muaj qhov pores hauv cov khoom siv crucible. nws yuav nqus noo noo, Yog li ntawd, lub crucible yuav tsum yogpreheated ua ntej siv los xyuas kom meej tias tsis muaj noo noo. Txwv tsis pub, cov cua kub ceev yuav ua rau lub crucible rautawg.

2) Ua ntej siv lub crucible tshiab thawj zaug, yog tias ua tau, txav lub crucible ze li ntawm lub qhov cub kom preheat rau 4-24 teev.

3) Ua ntej siv lub crucible tshiab, yog tias ua tau, muab cov ntoo tso rau hauv lub crucible kom hlawv rau 2-4 teev, uas yuav pab taucrucible rau dehumidify.

(2) Yuav ua li cas siv cov nplaim taws kub hnyiab tau

1) Txoj kev siv cov nplaim taws kub hnyiab yog qhov tseem ceeb heev. txoj kev tsis tsim nyog yuav ua rau crucible rautawg, tawg, tawg rau saum thiab lwm yam teeb meem. Ua ntej siv lub crucible, sau ib feem peb ntawm lub crucible nrogscraps, thiab ces preheat lub lauj kaub thiab cov khoom ua ke. Thaum preheating tsuas yog lub lauj kaub khoob, vim qhov hluav taws kub ceevntawm lub qhov cub pellet, lub lauj kaub khoob yuav kub heev, lub crucible yuav overheat, thiab paj yuav ntws.

2) Tom qab 1 lub hlis ntawm kev siv, nres lub qhov cub rau ib nrab hnub, nqa lub crucible tawm, thiab ntxuav cov pa roj carbon thiab tshauv sab nraumlub crucible. Siv cov txhuam txhuam hluav taws xob, thiab qhov no tuaj yeem ua rau cov thermal conductivity. Tig nws 90 degrees thiab muab tso raurau hauv qhov cub. Tiv thaiv kom tsis txhob muaj nplaim taws kub hnyiab hauv ib qho chaw txhua lub sijhawm.

3) Tom qab siv rau lwm ib thiab ib nrab lub hlis, tshem tawm lub crucible dua, ntxuav cov pa roj carbon, tig nws 90 degrees,thiab muab tso rau hauv qhov cub.

4) Thaum muab kev hloov pauv thiab noj mov, tsis txhob ntxiv cov khoom txias txias ntau dhau, yog tias koj ntxiv ntau dhau, sab sauvaluminium kua yuav solidify, ua rau sab sauv txias thiab sab qis yuav kub, thiab sab saum tojcrucible yuav tawg.

5) lf lub slag breaker yog ntxiv thaum lub sij hawm smelting, lub slag nyob rau hauv lub puab phab ntsa ntawm lub crucible yuav tsum tau ntxuav nyob rau hauv lub sij hawm,txwv tsis pub nws yuav corrode lub crucible thiab ua rau sab qis ntawm lub crucible kom nkag tau cov kua slag, Tib lub sijhawm,cov dross accumulated cuam tshuam lub tshav kub conduction ntawm lub crucible.
