Kab lus no yuav qhia txog cov txheej txheem tsim khoom ntawm magnesium ingots thiab qhov tseem ceeb ntawm qee cov thev naus laus zis tshiab rau kev lag luam magnesium.
Magnesium ingot ntau lawm txheej txheem
Magnesium yog cov hlau hnyav uas nws cov txheej txheem tsim khoom feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no:
1. Ore mining: Lub ntsiab ore ntawm magnesium yog magnesite, uas feem ntau muaj nyob rau hauv lub ntiaj teb crust. Ore mining feem ntau muaj cov kauj ruam xws li mining, ore crushing, thiab leaching kom tau cov magnesium-muaj ore.
2. Refining txheej txheem: Extracting ntshiab magnesium los ntawm magnesium ore yuav tsum tau ib tug series ntawm refining kauj ruam. Cov txheej txheem feem ntau yog Pidgeon txheej txheem thiab electrolysis.
1). Cov txheej txheem Pidgeon: Qhov no yog ib txoj hauv kev txo cov cua sov uas cuam tshuam nrog txo cov magnesium ore nrog rau cov thee ntawm qhov kub thiab txias kom tau txais magnesium tsawg dua. Txoj kev no tseem siv dav hauv qee qhov chaw, tab sis nws siv zog ntau dua thiab tsim cov khoom lag luam uas yuav tsum tau muab pov tseg.
2). Electrolysis: Electrolysis yog ib txoj hauv kev niaj hnub no uas tau txais magnesium purity siab los ntawm electrolyzing magnesium ntsev. Txoj kev no, feem ntau ua nyob rau hauv electrolysers, yuav tsum tau siv hluav taws xob tsawg dua thiab tsim cov khoom lag luam tsawg dua. Electrolysis tau dhau los ua neeg nyiam hauv kev lag luam magnesium.
3. Alloy Preparation: Magnesium alloys yuav tsum muaj nyob rau hauv feem ntau daim ntawv thov vim cov ntshiab magnesium muaj cov khoom siv tsis zoo. Kev npaj magnesium alloys feem ntau suav nrog kev sib xyaw cov magnesium ntshiab nrog lwm cov ntsiab lus alloying xws li txhuas, zinc, manganese, thiab lwm yam kom tau txais cov yam ntxwv ua tau zoo.
4. Casting thiab forming: Alloys feem ntau yog cam khwb cia nyob rau hauv lub xeev ua kua rau hauv ingots los yog lwm yam duab, thiab ces tshav kub kho thiab machined kom tau raws li cov kev xav tau ntawm kev siv sib txawv.
5. Kev tswj kom zoo: Thoob plaws hauv tag nrho cov txheej txheem tsim khoom, kev tswj kom zoo yog qhov tseem ceeb. Los ntawm kev tshuaj xyuas tshuaj, metallographic microscopy thiab lwm txoj hauv kev, peb xyuas kom meej tias qhov zoo ntawm cov khoom kawg ua tau raws li cov qauv.
Lub tswv yim thev naus laus zis ua rau kev nce siab ntawm magnesium kev lag luam
Nyob rau hauv xyoo tas los no, kev lag luam magnesium tau ua tiav zoo heev, ua tsaug rau kev siv cov thev naus laus zis tshiab:
1. High-temperature electrolysis technology: Tshiab high-temperature electrolysis technology ua rau cov ntshiab magnesium ntau npaum li cas thiab ib puag ncig tus phooj ywg. Txoj kev no yuav txo tau lub zog xav tau rau electrolysis thiab txo cov pa roj carbon hneev taw.
2. Magnesium alloys tshiab: Cov kws tshawb nrhiav txuas ntxiv tsim cov magnesium alloys tshiab kom tau raws li qhov xav tau ntawm ntau qhov chaw. Cov alloys no muaj zog dua, kev tiv thaiv corrosion thiab lub teeb yuag thiab siv dav hauv thaj chaw xws li kev lag luam tsheb, aerospace thiab khoom siv hluav taws xob tsim khoom.
3. Kev lag luam ncig: Kev lag luam magnesium tseem tab tom txhim kho nyob rau hauv kev coj noj coj ua zoo dua qub, siv cov qauv kev lag luam ncig thiab tsom mus rau kev rov ua dua tshiab thiab kev siv pov tseg kom txo tau kev vam khom ntawm cov peev txheej ntuj.
4. 3D tshuab luam ntawv: 3D tshuab luam ntawv tau tshwm sim hauv kev tsim khoom, thiab cov khoom siv magnesium kuj tau siv dav hauv 3D luam ntawv. Cov cuab yeej no tso cai rau kev tsim cov khoom sib xws, txhim kho kev tsim khoom.
5. Automation thiab ntse manufacturing: Daim ntawv thov ntawm automation thiab ntse manufacturing tshuab ua magnesium ntau npaum thiab tswj tau, txo qhov tshwm sim ntawm tib neeg yuam kev.
Feem ntau, cov txheej txheem tsim khoom ntawm magnesium ingots tau hloov mus tas li, thiab cov thev naus laus zis tshiab tau tsav txoj kev loj hlob ntawm kev lag luam no. Raws li kev thov loj hlob thiab kev siv thev naus laus zis nce ntxiv, magnesium yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, pab txhawb kev nce qib ntawm kev lag luam niaj hnub thiab thev naus laus zis. Nyob rau tib lub sijhawm, kev lag luam kuj tseem ua haujlwm hnyav los txo cov kev cuam tshuam ib puag ncig thiab ua kom muaj kev vam meej yav tom ntej.
