Tuam Tshoj Zoo Thermal Stability Graphite Rotor rau Aluminium Casting
Cov neeg yuav khoom txaus siab yog peb lub hom phiaj tseem ceeb ntawm.We uphold a consistent level of professionalism, quality, credibility and repair for Manufacturer of Good Thermal Stability Graphite Rotor for Aluminium Casting, Peb zoo siab txais tos cov neeg muas zaub tshiab thiab qub los ntawm txhua qhov chaw ntawm lub neej los tiv tauj peb rau yav tom ntej kev lag luam kev sib raug zoo thiab kev sib raug zoo!
Cov neeg yuav khoom txaus siab yog peb lub hom phiaj tseem ceeb ntawm.Peb txhawb nqa ib qib zoo ib yam ntawm kev tshaj lij, kev ua tau zoo, kev ntseeg siab thiab kho rauTuam Tshoj Graphite Rotor thiab Graphite Ncej, Peb kuj muaj lub peev xwm muaj zog ntawm kev sib koom ua ke los muab peb cov kev pabcuam zoo tshaj plaws, thiab npaj tsim lub tsev rau khoom hauv ntau lub tebchaws thoob ntiaj teb, uas yuav zoo li yooj yim rau kev pabcuam peb cov neeg siv khoom.
1. Lub graphite rotor ua haujlwm tsis tu ncua hauv aluminium yaj ntawm li 750 ° C ntawm qhov ceev ntawm 200r / min ~ 400r / min, thiab lub neej kev pabcuam dav dav yuav tsum ncav cuag ntau tshaj ib hlis.Lub graphite rotor ntawm peb lub tuam txhab yog ua los ntawm high-purity graphite.Qhov zoo ntawm graphite nws tus kheej muaj feem cuam tshuam rau lub neej kev pab cuam ntawm lub rotor.Nyob rau tib lub sijhawm, cov txheej txheem tiv thaiv oxidation yog siv rau ntawm qhov chaw, thiab lub neej kev pabcuam tuaj yeem txuas ntxiv mus rau 50-60 hnub.
2. Kev ua haujlwm ntawm graphite rotor:
Lub graphite rotor yog tsim los ntawm rotor pas nrig thiab nozzle.Lub tshuab kis tau tus mob tsav lub graphite rotor tig, thiab argon los yog nitrogen yog tshuab rau hauv txhuas yaj los ntawm rotor pas nrig thiab nozzle.Lub high-speed rotating graphite rotor lov cov argon los yog nitrogen gas nkag mus rau hauv lub txhuas yaj los ua ntau npuas me me, uas disperse lawv nyob rau hauv lub molten hlau.Thaum cov npuas nyob rau hauv kev sib cuag, cov npuas nyob rau hauv lub yaj cia siab rau cov pa ib feem ntawm lub siab sib txawv thiab lub hauv paus ntsiab lus ntawm deg adsorption kom nqus hydrogen nyob rau hauv lub yaj, adsorb oxidized slag, thiab muab tshem tawm ntawm lub melt nto raws li cov npuas nce mus purify. cov yaj.
Kev siv thiab kev saib xyuas ntawm graphite rotor:
- Lub rotating nozzle yog ua los ntawm high-purity graphite.Ntxiv nrog rau kev xav txog cov qauv ntawm lub nozzle kom tawg cov pa npuas, nws kuj siv lub zog centrifugal uas tsim los ntawm nplawm cov aluminium alloy yaj kom cov yaj nkag mus rau hauv lub nozzle thiab sib tov nrog cov kab rov tav ejected roj los tsim cov roj.or cov kua dej yog ejected los ua kom cov cheeb tsam sib cuag thiab lub sij hawm sib cuag ntawm cov npuas thiab cov kua txhuas txhuas, thiab txhim kho cov degassing thiab purification nyhuv.
2. Kev ua haujlwm dav dav yuav tsum muaj ntau tshaj ib hlis.Lub durability yog 3-4 lub sij hawm zoo tshaj qhov uas tsis yog-oxidizing rotor.Nws tuaj yeem kav ntev txog 55-65 hnub ntawm qhov kub ntawm 700 ° C, thiab tuaj yeem kav ntev txog 25-35 hnub ntawm qhov kub siab tshaj 1000 ° C.Nrog rau kev tiv thaiv oxidation tiv thaiv txheej rau saum npoo, kev pabcuam lub neej tuaj yeem txuas ntxiv mus rau 50-60 hnub.
3.Ua ntej immersing lub graphite rotor nyob rau hauv cov kua txhuas, preheat nws rau 5 feeb mus rau 10 feeb ntawm txog 100 mm saum cov kua nto kom tsis txhob muaj kev cuam tshuam ntawm ceev ceev ntawm cov khoom;Ua ntej lub rotor yog immersed nyob rau hauv cov kua, cov roj yuav tsum tau dhau los ntawm; Cov cua yuav tsum tau nres tsuas yog tom qab lub rotor nqa tawm ntawm cov kua theem, thiaj li yuav tiv thaiv cov huab cua qhov ntawm lub rotor nozzle los ntawm kev thaiv.
4. Lub ntsiab ua rau graphite rotor kev puas tsuaj yog kub-kub oxidation: lub ntsiab ntawm graphite yog carbon, thiab graphite tuaj yeem pom oxidized nyob rau hauv huab cua kub tshaj 600 ° C. Cov khoom ntawm cov pa roj carbon oxidation cov tshuaj tiv thaiv yog CO thiab CO2 gases, uas. tsis tuaj yeem tiv thaiv lub rotor.Feem ntau hais lus, lub thawv degassing tsis tuaj yeem raug kaw tag nrho, thiab feem ntau ntawm cov kab noj hniav sab hauv ntawm lub thawv tsis tau ntim nrog cov roj tiv thaiv, yog li oxidation ntawm graphite rotor yog inevitable.Raws li qhov tshwm sim ntawm nws cov oxidation, txoj kab uas hla ntawm lub rotor ncej maj mam txo kom txog thaum nws tawg thiab tawg.Cov neeg yuav khoom txaus siab yog peb lub hom phiaj tseem ceeb.We uphold a consistent level of professionalism, quality, credibility and repair for Manufacturer of Good Thermal Stability Graphite Rotor for Aluminium Casting, Peb zoo siab txais tos cov neeg muas zaub tshiab thiab qub los ntawm txhua qhov chaw ntawm lub neej los tiv tauj peb rau yav tom ntej kev lag luam kev sib raug zoo thiab kev sib raug zoo!
Chaw tsim tshuaj paus ntawmTuam Tshoj Graphite Rotor thiab Graphite Ncej, Peb kuj muaj lub peev xwm muaj zog ntawm kev sib koom ua ke los muab peb cov kev pabcuam zoo tshaj plaws, thiab npaj tsim lub tsev rau khoom hauv ntau lub tebchaws thoob ntiaj teb, uas yuav zoo li yooj yim rau kev pabcuam peb cov neeg siv khoom.
