Lub hauv paus ntsiab lus ntawm Ferromagnetic Kev Tshem Tawm Siv tau rau tshem tawm cov hlau los ntawm molten aluminium thaum lub sijhawm melting
Nws yog tsuas yog siv los tshem tawm cov hlau cov ntsiab lus los ntawm kev ua tsis zoo, ua kom zoo ntawm txhuas alloy thiab cov kev pabcuam lub neej ntawm cov khoom tiav ntawm cov khoom tiav. Muaj ob txoj hauv kev feem ntau rau kev tshem tawm cov hlau: kev siv tshuab siv hluav taws xob thiab hluav taws xob siv hluav taws xob. Kev lim tawm txhua yam yog cov txheej txheem ntawm kev lim tawm cov hlau impurities los ntawm ib lub lim mesh. Feem ntau siv lim mesh cov ntaub ntawv suav nrog cov ntsiab lus yooj yim vim tias cov teeb meem uas muaj teeb meem xws li tshem tawm cov khoom siv qeeb qeeb thiab txo qis.
Electromagnetic lim yog kev siv hluav taws xob teb kom tshem tawm cov hlau cov ntsiab lus los ntawm txhuas melt. Tus qauv ua haujlwm yog kom dhau cov lus melt los ntawm cov suab hluav taws xob teb, thiab cov hlau yaj hauv lub zog hluav taws xob, yog li ua tiav lub hom phiaj tshem tawm cov hlau. Hom no tuaj yeem txo cov ntsiab lus ntawm cov hlau keeb thiab yog qhov haum rau tshem tawm cov aluminium alloys nrog cov kab hlau siab.
Cov Khoom Siv Neeg Kho Tshuab
Cov cuab yeej siv txhua yam siv tau suav nrog cov ntxaij lim dej tsuas yog siv cov qauv sib txawv thiab tshem tawm cov qauv ntau thiab tshem tawm cov hlau los ntawm aluminium alloys ntawm cov khoom sib txawv.
Cov txheej txheem kev ua haujlwm yog raws li hauv qab no:
- Ntxiv aluminium alloy rau hauv lub cub tawg rau melting.
- Cov yaj ntws los ntawm lub lim thiab yog lim los ntawm ib qho mesh.
- Nquag ntxuav thiab hloov cov lim thiab cov ntxaij vab tshaus.
Nws muaj peb ntu: cov tsav tsheb, cov khoom siv hluav taws xob nrog kev txiav txim plaub, thiab chav sau slag. Ntawm lawv, lub teb hluav taws xob yog qhov tseem ceeb tshaj plaws, thiab cov hluav taws xob sib txawv tuaj yeem cuam tshuam los ntawm kev kho cov hluav taws xob.
Cov txheej txheem kev ua haujlwm yog raws li hauv qab no:
- Ntxiv aluminium alloy rau hauv lub cub tawg rau melting.
- Pib thiab kho cov ntsuas rau cov nqi tsim nyog.
- Cov yaj tau dhau los ntawm thaj chaw hluav taws xob, yog cov hlau tshem tawm, thiab ntws los ntawm kev sib sau slag sau chamber rau kev sau thiab ua.
