Graphite crucibleSilicon Carbide Graphite Crucibleyog lub thawv ntim ua ntawm graphite li cov khoom siv raw, yog li nws muaj cov tshuaj kub zoo thiab tuaj yeem siv rau hauv cov hlau lag luam smelting lossis casting. Piv txwv li, hauv lub neej txhua hnub, koj tuaj yeem nkag siab tias feem ntau cov tub lag luam nyob hauv cov chaw nyob deb nroog uas kho cov txhuv txhuas uas tau kho cov txhuv txhuas lossis cov lauj kaub txhuas. Cov cuab yeej lawv siv yog crucibles. Aluminium nplooj ntawv yog muab tso rau hauv Crucible thiab rhuab nrog hluav taws kom txog thaum lub lauj kaub, txias nws cia, thiab tom qab ntawd nws tuaj yeem siv. Txawm li cas los xij, graphite cruciles thiab silicon carbide crucailes yog siv hauv kev lag luam. Ntawm lawv, graphite cruci muaj zoo thermal conductivity, tab sis lawv tau nquag mus rau oxidation thiab muaj ib tus nqi puas tsuaj. Silicon carbide graphite crucibles muaj lub ntim loj dua thiab siv sijhawm ntev tshaj li graphite cruciles. Peb tau ua tshwj xeeb hauv kev muag khoom thiab kev tsim khoom ntawm cov crucibles rau 40 xyoo. Cov duab ntoo crucite peb tsim tawm tau dav rau smelting kub, khoom siv hluav taws xob, thiab cov khoom siv cua sov, thiab cov neeg siv hluav taws xob zoo nkauj rau lawv cov khoom lag luam qub zoo thiab ruaj khov. Peb kuj tseem ua kom muaj txiaj ntsig zoo ua txuj ci thev naus laus zis - yog cov khoom siv kub ua lag luam, cov txiaj ntsig zoo nkauj, thiab cov neeg siv khoom zoo, thiab cov tshuaj kub siab, thiab cov oxidation tsis kam. Nws cov kev pabcuam lub neej yog txawm tias muaj 3-5 zaug ntawm graphite crucaBles. Nyob rau tib lub sijhawm, nws txuag cov roj thiab txo kev ua haujlwm rau cov neeg ua haujlwm. Tus nqi ntawm kev txuag hluav taws xob isostatic siab crucibles thiab lub zog-txuag yog cov khoom lag luam no tau siv rau cov neeg tsis muaj hlau.
Graphite cross tuaj yeem siv rau hauv ntau lub tshuab cua sov, xws li cov hluav taws xob hluav taws xob, kub, xim, zinc, thiab alloys. Kho txoj kev teeb tsa rau graphite crucible thiab silicon carbide crucible
1. Lub hauv paus ntawm graphite crucible yuav tsum muaj tib yam lossis qhov siab ntawm cov crucible yuav tsum tau ua kom muaj hluav taws xob los ntawm kev txau mus rau crucible.
2. Thaum siv cov kab ke regractory raws li cov rooj ntoo uas muaj crucible, ncig refractory cib yuav tsum tau siv, uas yog tiaj thiab tsis khoov. Tsis txhob siv ib nrab lossis tsis sib haum pob zeb. Nws yog qhov zoo dua rau siv cov rooj ntoo crucable crucite.
3. Cov rooj ntoo plaub hau yuav tsum muab tso rau ntawm qhov chaw nruab nrab ntawm melting thiab yaj, nrog coke sib ro, los yog refractory rooj kom tsis txhob muaj adcesion ntawm crucible ntawm lub rooj ntoo. Tom qab tso cov crucible, nws yuav tsum muaj qib.
4. Qhov loj ntawm tus ntoo khaub lig thiab lub cev muaj zog yuav tsum sib phim, thiab qhov kev ncua deb ntawm tus ntoo khaub zig uas tsim nyog, tsawg kawg 40 hli lossis ntau dua.
Thaum thauj khoom beaked rau hauv lub cub tawg rau hauv lub cub tawg, ib qho sib txawv ntawm kwv yees li ntawm ib qho hauv qab ntawm crucible nozzle thiab tsis muaj dab tsi yuav tsum muab tso rau hauv qab. Lub nozzle thiab rauv taws yuav tsum tau smoothed nrog refractory refractory refractory refractory. Phab ntsa cua sov yuav tsum tau muaj cov cib refractory thiab cov crucible yuav tsum tau ua rau daim duab los ntawm 3 hli raws li qhov chaw nthuav dav ntawm cov cua sov tom qab cua sov.
Cov thev naus laus zis ntawm cov teeb meem txheej txheem yog qhov tseem ceeb los cuam tshuam hauv cov kev xws li cov qauv xws li cov qauv, cov khoom siv raw, cov cuab yeej siv ntau lawm, thiab thev naus laus zis. Hais txog cov khoom siv raw, peb tsuas yog siv refractory av nplaum, cov khoom xyaw, thiab lwm yam ntawm cov sib txawv ntawm ntau cov ntaub ntawv. Cov txheej txheem yog los ntawm kev ua ke compression, teb moulding, thiab tes moulding, uas yog graph moulding. Tom qab ua cov moulding, nws yog ib qho tseem ceeb kom nco ntsoov kom nws qhuav. Tom qab kuaj xyuas, nws yog tsim nyog, thiab cov khoom tsim nyog tuaj yeem ci ntsa iab
