Teeb duab Rotor

Lub graphite rotor thiab graphite impeller yog ua los ntawm high-purity graphite. Qhov saum npoo yog kho nrog tshwj xeeb los tiv thaiv kev tiv thaiv, thiab lub neej ua haujlwm yog kwv yees li 3 zaug ntawm cov khoom lag luam zoo ib yam. Nws yog dav siv hauv txhuas alloy casting kev lag luam.

Txoj kev ua kom huv txheej txheem ntawm kua txhuas hlau yog qhov tseem ceeb ntawm kev txhim kho kom ua tiav cov kev ua tiav ntawm aluminium alloy. Hauv cov txheej txheem ua kom huv si, txoj kev sib tov ntawm cov roj purification thiab cov kuab tshuaj thiab txau cov graphite rotor rau lub txhuas yaj kom kev ua kom huv yog qhov kev kho tshiab tshaj plaws hauv lub ntiaj teb. Lub ntsiab cai ua haujlwm ntawm graphite rotor yog: lub tshuab ua kom cov rotor rhuav tshem cov pa nitrogen (lossis argon) lub tshuab ua rau lub tshuab yaj ua rau cov roj yaj ua rau cov xov tooj ntawm cov pa tawg thiab cov khoom tawg tuaj rau hauv cov hlau tsis huv. Cov npuas hauv lub yaj yaj ntseeg cov roj ib feem ntawm qhov siab sib txawv thiab lub hauv paus ntsiab lus ntawm nto adsorption kom nqus tau hydrogen hauv cov yaj, adsorb oxidized slag, thiab yuav tsum tau tawm ntawm lub ntsej muag thaum cov npuas sawv, kom cov yaj tuaj yeem ua kom huv. Vim tias cov npuas me thiab tawg, lawv sib xyaw kom sib xyaw nrog lub tshuab yaj ua kom yaj, thiab tom qab ntawd lawv tig mus los ntawm qhov muab kauv los ua kom ntab qeeb. Lub sijhawm sib tiv tauj nrog cov yaj tau ntev, thiab cov huab cua ntws los ntawm txoj kab tawm tsis tu ncua yuav tsis tsim, yog li tshem cov teeb meem hydrogen hauv txhuas yaj. Txhim kho kev ua kom huv huv.

Rau cov khoom siv aluminium alloy foundries thiab aluminium khoom lag luam, nws yog qhov tseem ceeb heev kom txo cov nqi tsim nqi. Hauv kev hais txog qhov no, graphite rotors uas ua los ntawm peb lub tuam txhab tuaj yeem nqa cov txiaj ntsig hauv qab no. 1. Txo cov nqi khoom lag luam 2. Txo cov kev siv roj inert 3. Txo cov ntsiab lus aluminium nyob rau hauv slag 4. Txo cov nqi zog ua haujlwm 5. Txhim kho kev ua haujlwm, hloov lub sijhawm ntev dua 6. Txhim kho qhov ntseeg tau thiab txo tus nqi txij nkawm.

Vim tias cov kev qhia tshwj xeeb ntawm graphite rotors siv rau hauv txhua txoj kev siv los yog cov casting-dov cov kab ntau lawm tsis zoo li qub. Ua ntej, cov qhua tuaj noj mov muab cov qauv kos duab tsim thiab thawm hauv cov tiav graphite rotor teb siv daim ntawv ntsuam xyuas ib puag ncig. Tom qab ntawd, raws li cov duab kos, ua ke nrog graphite rotor nrawm, kev taw qhia kev sib hloov thiab nws qhov chaw sib piv mus rau aluminium kua theem, kev txheeb xyuas kev paub yog nqa tawm, thiab qhov tsim nyog tiv thaiv kev yaig. Kev pab kho oxidation.

Lub graphite rotor tig nozzle yog ua los ntawm high-purity graphite. Ntxiv nrog rau kev xav txog qhov yuav tsum tau tawg lub npuas, cov qauv nozzle tseem siv lub zog centrifugal tsim los ntawm kev nplawm cov aluminium alloy yaj kom cov melt nkag mus rau lub nozzle thiab tusyees sib tov nrog cov kab rov tav ua rau roj los tsim roj / Lub dav hlau ua kua. yog txau kom ua rau thaj chaw tiv tauj thiab sib tiv tauj lub sijhawm ntawm npuas thiab txhuas lub zog ua kua, thiab txhim kho cov nyhuv degassing purification.

Kev ceev nrawm ntawm graphite rotor tuaj yeem kho steplessly los ntawm cov hloov hluav taws xob hloov ceev ceev, nce mus txog 700r / min. Qhov tshwj xeeb ntawm graphite rotor yog Φ70mm ～ 250mm, thiab qhov tshwj xeeb ntawm tus impeller yog Φ85mm ～ 350mm. Lub siab-purity los tiv thaiv oxidation graphite rotor muaj cov yam ntxwv ntawm lub zog muaj zog, siab kub ua hauj, thiab txhuas ntws corrosion kuj. Hauv kev ua haujlwm ntawm kev ua kom huv thiab degassing, lub nplaim aluminium alloy kua hauv lub thawv yog them nrog nitrogen rau kev tiv thaiv, thiaj li hais tias ib feem ntawm graphite rotor kis los ntawm aluminium alloy kua yog nyob rau hauv inert roj los tiv thaiv kub kub oxidation ntawm lub rotor thiab rub lub neej ntev kev pabcuam ntawm rotor.

Cov duab ntawm lub impeller yog hloov kho, uas tuaj yeem txo qhov tsis kam thaum lub sij hawm tig, thiab kev sib txhuam thiab kev quab yuam ntawm lub impeller thiab aluminium alloy kua kuj tseem me me. Yog li kom tus nqi tsis sib npaug yog siab dua 50%, ua kom lub sijhawm smelting luv luv thiab txo cov nqi tsim khoom.
