Peb lub tuam txhab tau tsim tawm tshiab los tiv thaiv oxidationgraphite degassing rotor ua los ntawm high-purity graphite tau attracted thoob plaws hauv lub lag luam. Covdegassing rotor Tsis tsuas yog txhim kho cov nyhuv purification ntawm aluminium alloy yaj, tab sis kuj tseem txuas ntxiv lub neej kev pab cuam ntawm cov cuab yeej, nqa cov txiaj ntsig tseem ceeb rau kev lag luam aluminium alloy ntau lawm.
Kev tiv thaiv oxidationdegassing rotor yog ua los ntawm high-purity graphite, thiab qhov zoo ntawm cov graphite ncaj qha cuam tshuam lub durability ntawm lub rotor. Los ntawm cov txheej txheem tshwj xeeb thiab kev siv cov txheej txheem tiv thaiv oxidation ntawm qhov chaw, kev pabcuam lub neej ntawm lub rotor txuas ntxiv los ntawm cov tsoos 30 hnub mus rau 50-60 hnub, txhim kho kev ua haujlwm zoo ntawm cov khoom siv.
Lub hom phiaj tseem ceeb ntawm covdegassing rotor yog purify kua aluminium alloy. Cov txheej txheem purification ntawm kua aluminium alloy yog ib qho tseem ceeb txhais tau tias los txhim kho cov kev ua tau zoo ntawm txhuas alloy. Hauv qhov txheej txheem no, adegassing rotor yog siv los sib tov cov roj purification thiab hnyav, thiab tom qab ntawd tshuab nws mus rau hauv aluminium yaj los ntawm txoj kev txhaj tshuaj rotating. Qhov no suav hais tias yog cov cuab yeej siv siab tshaj plaws tam sim no. Lub hauv paus ntsiab lus ntawm kev ua haujlwmdegassing rotor yog raws li ib tug system uas muaj ib tug rotor pas nrig thiab ib lub nozzle, uas disperses argon los yog nitrogen mus rau hauv countless me npuas nyob rau hauv kev kub ceev thiab disperses lawv nyob rau hauv lub molten hlau. Cov npuas no nqus hydrogen thiab oxides hauv cov yaj los ntawm cov hauv paus ntsiab lus ntawm cov pa roj sib txawv thiab qhov chaw adsorption, thiab thaum kawg coj lawv tawm ntawm qhov chaw yaj kom ua kom huv.
Hais txog kev siv thiab tu, tshwj xeeb yuav tsum tau them rau cov ntsiab lus hauv qab no:
Lub rotating nozzle ntawm lubdegassing rotor yog ua los ntawm high-purity graphite, uas yog tsim los disperse npuas thiab siv centrifugal quab yuam kom tusyees sib tov cov pa roj-kua ntws, yog li ua rau cov cheeb tsam sib cuag thiab lub sij hawm ntawm npuas thiab txhuas alloy kua, thiab txhim khu cov nyhuv purification.
Tom qab ua tiav, lub siab kub resistantdegassing rotor muaj kev pab lub neej ntawm 55-65 hnub ntawm 700°C thiab 25-35 hnub ntawm 1000°C. Daim ntawv thov ntawm cov txheej tiv thaiv saum npoo txuas ntxiv nws lub neej kev pabcuam rau 50-60 hnub.
Yuav kom ncua lub neej kev pab cuam ntawm lubdegassing rotor, nws raug pom zoo kom preheat nws rau 5-10 feeb ntawm ib txoj hauj lwm txog 100 hli ntawm cov kua nto ua ntej muab tso rau hauv cov kua txhuas kom tsis txhob muaj kev cuam tshuam ntawm cov cua txias ntawm cov khoom. Cov roj yuav tsum tau qhia ua ntej lub rotor yog raus rau hauv cov kua, thiab cov khoom siv roj yuav tsum tau nres tom qab lub rotor tawm ntawm cov kua dej los tiv thaiv lub nozzle los ntawm clogging.
Qhov tseem ceeb ntawm kev puas tsuaj raudegassing rotors yog kub-kub oxidation. Graphite yuav raug oxidation tseem ceeb hauv huab cua ntawm qhov kub siab tshaj 600°C, tsim CO thiab CO2 gases, ua rau lub rotor txoj kab uas hla yuav maj mam txo kom txog thaum nws tawg thiab yuav siv tsis tau.
Los ntawm optimizing cov khoom siv thiab kev siv tshuab ntawm lubdegassing rotor, cov khoom no qhia tau hais tias kev ua tau zoo heev thiab cov txiaj ntsig kev lag luam hauv kev lag luam ntawm aluminium kua purification, kos ib qhov siab tshiab hauv aluminium alloy ntau lawm technology. Manufacturing tuam txhab uas muag xaiv hom nodegassing rotor tuaj yeem tsis tsuas yog txhim kho kev tsim khoom, tab sis kuj txo cov nqi kho cov cuab yeej, uas tsim nyog rau kev siv dav dav.
