Keeb kwm
Nyob rau hauv peb lub teb chaws, calcium tau tshwm sim nyob rau hauv daim ntawv ntawm hlau, uas hnub rov qab mus rau ib tug ntawm cov tseem ceeb tej yaam num pab los ntawm lub Soviet Union rau peb lub teb chaws ua ntej 1958, ib tug tub rog industrial enterprise nyob rau hauv Baotou. Nrog rau txoj kev ua kua cathode (electrolysis) hlau calcium ntau lawm kab. Xyoo 1961, qhov kev sim me me tau tsim cov hlau calcium uas tsim nyog.
Kev loj hlob:
Hnub mus txog rau xyoo 1980s txog rau thaum ntxov 1990s, nrog rau lub teb chaws txoj kev hloov kho ntawm cov tub rog kev lag luam thiab cov tswv yim ntawm "tub rog-rau-civilian" txoj cai, hlau calcium pib nkag mus rau hauv pej xeem kev lag luam. Xyoo 2003, raws li kev lag luam xav tau hlau calcium txuas ntxiv mus ntxiv, Baotou City tau dhau los ua lub teb chaws loj tshaj plaws hlau calcium ntau lawm, Qhov twg muaj plaub electrolytic calcium ntau lawm kab, nrog rau ib xyoos ib zaug muaj peev xwm ntawm 5,000 tons ntawm hlau calcium thiab cov khoom.
Qhov tshwm sim ntawm Calcium Aluminium Alloy:
Vim lub siab melting point ntawm metallic calcium (851 ° C), calcium burning poob nyob rau hauv tus txheej txheem ntawm ntxiv metallic calcium rau molten lead kua yog siab li ntawm 10%, uas ua rau cov nqi siab dua, nyuaj muaj pes tsawg leeg tswj, thiab ntev. lub sij hawm-siv zog noj. Yog li ntawd, nws yog ib qho tsim nyog los tsim cov hlau alloy nrog hlau aluminium thiab hlau calcium kom maj mam yaj txheej los ntawm txheej. Cov tsos ntawm calcium aluminium alloy yog precisely aimed ntawm kev daws qhov teeb meem no nyob rau hauv lub npaj txheej txheem ntawm txhuas calcium aluminium alloy.

Kev tsim cov calcium aluminium alloy yog txheej txheem ntawm melting thiab fusing nyob rau hauv lub nqus tsev vacuum siv kub raws li ib tug tej yam ratio ntawm hlau calcium thiab hlau txhuas.
Kev faib tawm ntawm Calcium Aluminium Alloy:
Calcium aluminium alloy feem ntau cais 70-75% calcium, 25-30% aluminium; 80-85% calcium, 15-20% aluminium; thiab 70-75% calcium 25-30%. Nws tuaj yeem raug kho raws li qhov yuav tsum tau ua. Calcium aluminium alloy muaj cov xim hlau zoo nkauj, qhov muaj sia nyob, thiab cov hmoov zoo yog qhov yooj yim rau hlawv hauv huab cua. Nws yog tsuas yog siv los ua tus tswv alloy, refining thiab txo tus neeg sawv cev hauv cov hlau smelting. Cov khoom tau muab rau hauv daim ntawv ntawm ntuj blocks, thiab tuaj yeem ua tiav rau hauv cov khoom sib txawv raws li cov neeg siv xav tau.
Qhov Zoo Classification ntawm
Raws li tus tswv alloy, cov kev xav tau zoo rau calcium aluminium alloy yog nruj heev. (1) Cov ntsiab lus ntawm cov hlau calcium fluctuates nyob rau hauv ib qho me me; (2) Lub alloy yuav tsum tsis txhob muaj kev sib cais; (3) Kev puas tsuaj impurities yuav tsum tau tswj nyob rau hauv ntau yam tsim nyog; (4) Yuav tsum tsis muaj oxidation ntawm qhov chaw ntawm cov hlau; Nyob rau tib lub sijhawm, kev tsim khoom, ntim khoom, kev thauj mus los thiab kev khaws cia ntawm calcium aluminium alloy yuav tsum tau ua raws li cov txheej txheem yuav tsum tau nruj me ntsis tswj. Thiab cov chaw tsim khoom ntawm calcium-aluminium alloys peb muab yuav tsum muaj cov qauv tsim nyog.
Kev thauj mus los thiab khaws cia
Cov khoom siv tshuaj ntawm calcium aluminium alloy yog nquag nquag. Nws yog qhov yooj yim rau oxidize thiab hlawv yooj yim thaum raug hluav taws, dej thiab cuam tshuam loj heev.
1. Ntim
Tom qab cov calcium aluminium alloy yog crushed raws li ib qho kev qhia tshwj xeeb, nws muab tso rau hauv lub hnab yas, hnyav, ntim nrog argon gas, kub-sealed, thiab ces muab tso rau hauv ib lub nruas hlau (ntsuas thoob ntiaj teb lub nruas). Lub thoob hlau muaj dej tsis zoo, huab cua cais tawm thiab tiv thaiv kev cuam tshuam.
2. Chaw thau khoom thiab tshem tawm
Thaum lub sijhawm thauj khoom thiab tshem tawm, forklift lossis crane (hluav taws xob hoist) yuav tsum tau siv rau kev thauj khoom thiab tshem tawm. Hlau nruas yuav tsum tsis txhob muab dov los yog pov tseg kom tsis txhob muaj kev puas tsuaj rau lub hnab ntim khoom thiab tsis muaj kev tiv thaiv. Cov mob hnyav dua tuaj yeem ua rau hlawv ntawm calcium aluminium alloy hauv lub nruas.
3. Kev thauj mus los
Thaum lub sij hawm kev thauj mus los, tsom rau kev tiv thaiv hluav taws, tiv thaiv dej thiab tiv thaiv kev cuam tshuam.
4. Cia
Lub txee lub neej ntawm calcium aluminium alloy yog 3 lub hlis tsis qhib lub thoob. Calcium aluminium alloy yuav tsum tsis txhob muab khaws cia rau hauv qhov qhib, thiab yuav tsum muab cia rau hauv qhov chaw qhuav, nag-pov thawj warehouse. Tom qab qhib lub hnab ntim khoom, nws yuav tsum tau siv ntau li ntau tau. Yog tias cov hlau tsis tuaj yeem siv tau ib zaug, huab cua hauv lub hnab ntim khoom yuav tsum tau tso tseg. khi lub qhov ncauj kom nruj nrog ib txoj hlua, thiab muab nws rov qab rau hauv lub nruas hlau. Foob los tiv thaiv alloy oxidation.
5. Nws yog nruj me ntsis txwv tsis pub crushing calcium-aluminium alloy nyob rau hauv cov hlau nruas los yog lub hnab ntim khoom uas muaj calcium-aluminium alloy kom tsis txhob muaj hluav taws. Lub crushing ntawm calcium aluminium alloy yuav tsum tau nqa tawm ntawm lub phaj txhuas.
