Dab tsi yog technical parameters ntawm Graphite Degassing Rotor?
Raws li ib tug ua lag luam ntawm graphite degassing rotors, kuv feem ntau nug txog cov kev tsis ua hauj lwm uas txhais cov yam tseem ceeb ntawm cov hlau - smelting kev lag luam. Graphite degassing rotors ua lub luag haujlwm tseem ceeb hauv kev tshem tawm hydrogen thiab lwm yam impurities los ntawm cov hlau molten, txhim kho qhov zoo ntawm cov khoom hlau kawg. Nyob rau hauv no blog, kuv yuav delve rau hauv qhov tseem ceeb technical parameters ntawm graphite degassing rotors.
1. Khoom zoo
Qhov zoo ntawm graphite siv nyob rau hauv lub rotor yog qhov tseem ceeb tshaj plaws. Siab - purity graphite yog qhov zoo dua vim nws muaj cov thermal conductivity zoo heev, tshuaj tiv thaiv, thiab txhua yam muaj zog ntawm qhov kub thiab txias. Peb cov graphite degassing rotors yog tsim los ntawm hwm - qib graphite cov ntaub ntawv nrog cov ntsiab lus carbon feem ntau siab dua 99%. Qhov siab no - purity graphite xyuas kom meej tias lub rotor tuaj yeem tiv taus qhov hnyav ntawm cov hlau molten yam tsis muaj kev puas tsuaj loj. Cov graphite kuj tseem muaj cov qauv zoo - grained qauv, uas txhim kho nws cov hnav tsis kam thiab txo qhov tshwm sim ntawm particle shedding rau hauv cov hlau molten.
2. Qhov ntev
Qhov ntev ntawm graphite degassing rotor yog ua tib zoo tsim kom tau raws li cov kev cai tshwj xeeb ntawm cov hlau sib txawv - cov txheej txheem smelting. Qhov ntev ntawm lub rotor yog ib qho tseem ceeb parameter. Cov rotors ntev dua yog tsim rau qhov loj dua degassing units thiab tob molten hlau da dej. Txoj kab uas hla ntawm lub rotor cuam tshuam qhov ceev ntawm cov pa dispersion thiab efficiency ntawm degassing. Ib txoj kab uas hla loj dua tuaj yeem tsim cov npuas roj ntau dua, thaum lub rotor me me tuaj yeem tsim cov npuas zoo dua, uas yuav ua tau zoo dua hauv qee qhov kev siv.
Piv txwv li, nyob rau hauv txhuas smelting, rotors nrog diameters li ntawm 50mm mus rau 150mm thiab ntev los ntawm 300mm mus rau 1000mm yog feem ntau siv. Cov duab ntawm lub rotor kuj txawv. Qee cov rotors muaj ib qho yooj yim cylindrical zoo li, thaum lwm tus yuav muaj tshwj xeeb tsim cov hniav los yog vanes los txhim kho cov pa roj - kua sib tov. Cov hniav no tuaj yeem tsim nyob rau hauv cov duab sib txawv, xws li helical lossis ncaj, txhawm rau txhim kho cov txheej txheem degassing.
3. Kev sib hloov ceev
Kev sib hloov ceev ntawm graphite degassing rotor yog qhov tseem ceeb tsis zoo uas cuam tshuam ncaj qha rau kev ua haujlwm degassing. Kev sib hloov ceev dua tuaj yeem rhuav tshem cov roj rau hauv cov npuas me, ua rau thaj tsam ntawm kev sib cuag ntawm cov roj thiab cov hlau molten. Qhov no, nyob rau hauv lem, txhawb kev loj hlob zoo dua thiab kev tshem tawm ntawm hydrogen thiab lwm yam impurities. Txawm li cas los xij, kev sib hloov ntau dhau kuj tuaj yeem ua rau ntau dhau ntawm cov hlau molten thiab tuaj yeem ua rau muaj zog ntawm lub rotor.
Feem ntau, kev sib hloov ceev ntawm graphite degassing rotors nyob ntawm 100 mus rau 600 revolutions ib feeb (RPM). Qhov zoo tshaj plaws kev sib hloov ceev nyob ntawm seb yam xws li hom hlau, qhov luaj li cas ntawm lub degassing chav tsev, thiab qhov xav tau qib ntawm degassing. Piv txwv li, nyob rau hauv magnesium smelting, ib tug kuj qis rotational ceev yuav siv tau kom tsis txhob muaj ntau oxidation, thaum nyob rau hauv ib co siab - ntim aluminium smelting ua hauj lwm, ib tug ntau dua ceev yuav ua hauj lwm kom ua tau sai degassing.
4. Gas Flow Rate
Cov roj ntws tus nqi yog lwm qhov kev ntsuas tseem ceeb. Cov pa roj, feem ntau yog argon lossis nitrogen, yog nkag los ntawm rotor rau hauv cov hlau molten. Tus nqi ntws ntawm cov pa cuam tshuam rau tus naj npawb thiab qhov loj ntawm cov npuas tsim. Cov pa roj ntau dua tuaj yeem tsim cov npuas ntau dua, tab sis yog tias tus nqi ntws siab dhau lawm, cov npuas yuav coalesce thiab ua tsis tau zoo hauv degassing.
Qhov tsim nyog cov roj ntws tau txiav txim siab raws li qhov ntim ntawm cov hlau molten, hom hlau, thiab cov kev xav tau degassing. Feem ntau, cov pa roj ntws rau graphite degassing rotors muaj li ntawm 5 txog 50 litres ib feeb. Piv txwv li, nyob rau hauv ib tug me me - scale aluminium casting lag luam, ib tug roj txaus tus nqi ntawm ib ncig ntawm 10 - 15 liters ib feeb yuav txaus, thaum nyob rau hauv ib tug loj - scale aluminium ingot ntau lawm cog, ib tug txaus tus nqi ntawm 30 - 50 litres ib feeb yuav tsum tau.
5. Kev tiv thaiv kub
Graphite degassing rotors yuav tsum muaj peev xwm tiv taus qhov kub ntawm cov hlau molten. Cov hlau sib txawv muaj cov ntsiab lus melting sib txawv, thiab lub rotor yuav tsum tswj hwm nws cov qauv kev ncaj ncees thiab kev ua haujlwm ntawm qhov kub siab no. Aluminium muaj qhov melting point ntawm ib ncig ntawm 660 degree, thaum qee cov hlau tuaj yeem muaj cov ntsiab lus melting saum 1500 degree.
Peb cov graphite degassing rotors yog tsim los tiv taus kub txog 1800 degree. Qhov siab - kub tsis kam yog ua tiav los ntawm kev siv siab - cov khoom graphite zoo thiab cov txheej txheem tsim khoom. Ntawm qhov kub thiab txias, cov graphite tsis yooj yim deform lossis hnov mob nrog cov hlau molten, ua kom lub sijhawm ntev - thiab txhim khu kev qha.
6. Hnav tsis kam
Vim muaj kev sib cuag tsis tu ncua nrog cov hlau molten thiab siab - kev sib hloov ceev, hnav tsis kam yog qhov tseem ceeb ntawm graphite degassing rotors. Kev hnav ntawm rotor tuaj yeem cuam tshuam rau nws qhov kev ua tau zoo thiab kev ua neej nyob. Cov yam ntxwv xws li hom molten hlau, muaj cov khoom abrasive hauv cov hlau, thiab kev sib hloov ceev txhua yam cuam tshuam rau tus nqi hnav.
Txhawm rau txhim kho kev hnav tsis kam, peb cov rotors raug kho nrog cov txheej tshwj xeeb lossis kev kho saum npoo. Cov kev kho mob no tuaj yeem tsim cov txheej txheem tiv thaiv ntawm cov graphite, txo qhov kev sib cuag ncaj qha ntawm cov graphite thiab cov hlau molten thiab txo qis hnav. Tsis tas li ntawd, qhov zoo - grained qauv ntawm graphite nws tus kheej kuj pab txhawb rau nws hnav - resistant zog.
7. Kev sib raug zoo nrog lwm cov khoom siv graphite
Hauv cov hlau - smelting kev lag luam, graphite degassing rotors feem ntau ua haujlwm nrog lwm cov khoom siv graphite xws li Graphite Tube, Graphite Moulds rau Nruam Casting, thiab Graphite Stopper. Kev sib raug zoo ntawm cov khoom no yog qhov tseem ceeb rau kev ua kom zoo thiab ua haujlwm zoo ntawm cov hlau - smelting txheej txheem.
Piv txwv li, graphite raj yuav siv tau los muab cov pa roj rau lub degassing rotor. Qhov ntev thiab txoj kev sib txuas ntawm lub raj thiab lub rotor yuav tsum tau ua kom zoo - sib txuam kom ntseeg tau tias muaj roj txaus. Ib yam li ntawd, thaum siv cov txheej txheem nruam - casting, graphite degassing rotor yuav tsum tau sib haum nrog cov graphite pwm kom tswj tau qhov zoo ntawm cov cam khwb cia hlau.
Hauv kev xaus, cov kev tsis sib xws ntawm graphite degassing rotors tau ua tib zoo tsim kom tau raws li cov kev xav tau sib txawv ntawm cov hlau - smelting kev lag luam. Los ntawm kev nkag siab txog cov kev txwv no, hlau - smelting cov tswv tuaj yeem xaiv cov graphite degassing rotors uas tsim nyog tshaj plaws rau lawv cov kev siv tshwj xeeb, txhim kho lawv cov khoom hlau zoo thiab ua kom cov khoom ua tau zoo.
