Kev tsim siv tshuab ntawm graphite cruci crucles rau smelting tooj liab tab tom hloov kho. Cov txheej txheem no siv lub ntiaj teb no tshaj plaws txias tshaj plaws ntawm 600MPA los xyuas kom meej tias kev kub siab ntawm tus crucible ntawm tus ntoo khaub lig thiab qhov tsis muaj zog thiab muaj zog heev. Qhov kev hloov tshiab no tsis tsuas yog txhim kho kev ua tau zoo ntawm Crucible, tab sis kuj ua rau muaj kev tiv thaiv loj hauv kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
Qhov Zoo Ntawm Qhov Txias Txias Isostatic Xovxwm
Sab hauv cov qauv yog cov khaub ncaws zoo nkauj thiab qhov tsis muaj kev ywj pheej
Nyob rau hauv cov qauv hluav taws xob siab ntawm lub copper-graphite crucible yog qhov tsis tshua muaj khaub ncaws tsis muaj kev tsis pom zoo. Qhov no yog nyob rau hauv stark sib piv rau cov qauv ib txwm txiav. Vim yog qhov qis dua, cov txheej txheem ib txwm muaj ua rau sab hauv qhov tsis xws luag uas cuam tshuam rau nws lub zog thiab thermal conductivity.
Siab zog, phab ntsa nyias ntoo
Tus mob khaub thuas isostatic nias txoj kev sib txuas tau txhim kho lub zog ntawm cov crucible nyob rau hauv kev kub siab. Lub zog ntau dua tso cai rau phab ntsa Crucible los ua thinner, yog li nce thermal conductivity thiab txo hluav taws xob kev siv hluav taws xob. Piv nrog cov tsoos cruciBles, qhov tshiab ntawm cov crucible yog qhov tsim nyog rau kev ua kom zoo thiab txuag hluav taws xob.
Zoo heev Thermal Conductivity thiab Tsawg Zog Kev Siv
Lub zog siab thiab cov qauv nyias nyias muaj cov qauv ntawm Molten tooj liab grucite crucition crucite ua kom zoo dua thermal conductivity piv rau cov cruciles. Txhim kho cov thermal conductivity txhais tau tias cua sov tuaj yeem hloov tau ntau tusyees thiab nrawm thaum lub sij hawm smelloting thiab sprowle txo kev siv hluav taws xob thiab kev txhim kho ntau lawm ua tau zoo.
Kev sib piv nrog cov txheej txheem tsoosing
Cov kev txwv ntawm kev txiav txoj kev
Feem ntau ntawm cov kev tsim qauv graphite crucibles yog tsim los ntawm txiav thiab tom qab ntawd sintering. Cov qauv no ua rau tsis ncaj, qhov tsis zoo, thiab qis-zog sab hauv cov qauv vim txo siab. Tsis tas li ntawd, nws muaj kev txom nyem thermal conductivity thiab kev siv hluav taws xob siab, ua rau nws nyuaj ua tau raws li kev yuav tsum tau ua haujlwm ntawm kev ua haujlwm niaj hnub thiab txuag hluav taws xob.
Qhov tsis zoo ntawm cov imitators
Qee cov tuam ntxhab qog tus mob khaub thuas isosteratic nias txoj kev los tsim cov tawv nqaij, tab sis vim cov khoom lag luam tsis txaus, feem ntau tsim cov pob zeb Silicon carbide crucailes. Cov crucailes no muaj cov phab ntsa thicker, cov thermal delity conductivity, thiab muaj zog siv hluav taws xob tsim los ntawm txias ostatic nias.
Cov ntsiab lus thiab cov ntawv thov
Hauv cov txheej txheem smelting ntawm txhuas thiab zinc alloys, oxidation tsis kam thiab thermal conductivity ntawm crucible yog qhov tseem ceeb. Cruciles tau siv tus khaub thuas yog iSostatic nias cov txheej txheem muab kev cuam tshuam tshwj xeeb thaum tsis txhob muaj kev cuam tshuam zoo ntawm cov tshuaj fluoride-muaj. Cov crucaids tswj tau zoo heev ntawm kev kub siab ntau yam tsis muaj paug rau cov hlau, txhim kho kom daws tau lub siab.
Daim Ntawv Thov Hauv Aluminium Alloy SMELTING
Graphite crucable ua si tseem ceeb ntawm lub luag hauj lwm tseem ceeb hauv kev melting ntawm alloys alloys, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom tuag thiab cov khoom siv. Lub suab kub yaj ntawm aluminium alloy yog nruab nrab ntawm 700 ° C thiab 750 ° C, uas yog qhov ntsuas kub thiab txias uas yooj yim oxidized. Yog li ntawd, graphite crucibles tsim los ntawm txias ostatic nias qhov chaw tshwj xeeb ntawm oxidation tiv thaiv kom ntseeg tau tias kev ua tau zoo heev ntawm kev kub ntxhov.
Tsim rau cov hau kev sib txawv
Graphite Crucible yog haum rau ntau txoj kev smelting, suav nrog ib qho-cub tawg thiab smelting ua ke nrog kev tiv thaiv cua sov. Rau txhuas alloy casts castings, tsim qauv crucible xav tau kom tau raws li kev tiv thaiv kev xav tau ntawm kev tiv thaiv h2 kev sib xyaw ua ke, yog li tus txheem ntoo khaublig lossis cov khoom ntoo loj loj. Nyob rau hauv beneracized smelting rauv yas, tilting Crucible Furnaces feem ntau yog siv los rov ua dua cov khib nyiab smelting.
Piv ntawm cov kev ua tau zoo
Siab ceev thiab thermal conductivity
Qhov ceev ntawm graphite crucailes tsim los ntawm kev txias isostatic nias yog nruab nrab ntawm 2.2 thiab 2.3, uas yog qhov ntom heev ntawm cov neeg tawv nqaij hauv ntiaj teb. Qhov ceev no siab muab cov qhov muag daj ua kom zoo tshaj plaws thermal conductivity, tseem zoo dua li lwm cov npe ntawm cov crucaibles.
Ci ntsa iab thiab corrosion tsis kam
Qhov saum npoo ntawm molten aluminium Graphite Crucible yog them nrog plaub txheej ntawm cov khoom siv ua tuab, uas yog txhim kho cov crucuity, uas txhim kho nws lub neej pabcuam. Nyob rau hauv sib piv, kev ua haujlwm hauv tsev tsuas muaj cov txheej txheem ntawm cov xis nyob rau saum npoo, uas yog yooj yim puas thiab ua rau thaum ntxov oxidation ntawm crucible.
Muaj pes tsawg leeg thiab thermal conductivity
Molten tooj liab grucite crucible siv ntuj graphite, uas muaj cov thermal zoo thermal. Nyob rau hauv sib piv, nyeg graphite cruciLes siv cov khoom siv hluavtaws, txo cov av nplaum kom txo tau cov av nplaum rau molding, yog li cov thermal conductivity yog qhov txo qis.
Ntim thiab chaw thov
Yam ntim
Molten tooj liab graphite crucite crucite crucite yog feem ntau bundled thiab ntim nrog cov hlua straw, uas yog txoj kev yooj yim thiab tswv yim.
Kev nthuav dav ntawm cov ntawv thov
Nrog kev nce qib nruam ntawm kev siv thev naus laus zis, cov ntawv thov ntawm graphite crucas crucibles txuas ntxiv nthuav. Tshwj xeeb tshaj yog nyob rau hauv kev tsim cov txhuas alloy tuag casings thiab maj mam hloov cov khoom lag luam pov tseg ntawm cov khoom lag luam zoo.
Hauv kev xaus
Daim ntawv thov ntawm cov khaub thuas yog cov txheej txheem nias txoj kev tau coj cov kev ua tau zoo thiab ua haujlwm ntawm tooj liab-graphite crucible smelting rau qib tshiab. Txawm hais tias nws yog kev sib dhos, lub zog lossis thermal conductivity ntawm tus qauv sab hauv, nws yog qhov zoo dua li kev tsim khoom lag luam. Nrog rau kev thov thoob plaws ntawm cov thev naus laus zis siab tshaj plaws, kev lag luam xav nthuav dav, tsav tag nrho kev lag luam rau ib qho kev ua haujlwm zoo thiab ib puag ncig zoo.
