Kakaretso ea Aluminium Ingot Casting Process

I. Selelekela

Boleng ba aluminium ea mantlha e hlahisoang ka liseleng tsa aluminium electrolytic e fapana haholo, 'me e na le litšila tse fapaneng tsa tšepe, likhase le li-inclusions tse se nang tšepe tse tiileng.Mosebetsi oa aluminium ingot casting ke ho ntlafatsa tšebeliso ea mokelikeli oa aluminium oa boemo bo tlaase le ho tlosa litšila ka hohle kamoo ho ka khonehang.

II.Sehlopha sa Aluminium Ingots

Li-ingots tsa aluminium li arotsoe ka mefuta e meraro ho latela sebopeho: li-ingots tse remelting, li-ingots tsa aluminium tse hloekileng haholo, le li-ingots tsa aluminium alloy.Li ka boela tsa aroloa ka sebopeho le boholo, joalo ka li-ingots tsa slab, li-ingots tse chitja, li-ingots tsa poleiti le li-ingots tse bōpehileng joaloka T.Ka tlase ho na le mefuta e 'maloa e tloaelehileng ea li-ingots tsa aluminium:

Li-ingots tse lokisang: 15kg, 20kg (≤99.80% Al)

Li-ingots tse bōpehileng joaloka T: 500kg, 1000kg (≤99.80% Al)

Li-ingots tsa aluminium tse hloekileng haholo: 10kg, 15kg (99.90% ~ 99.999% Al)

Aluminium alloy ingots: 10kg, 15kg (Al-Si, Al-Cu, Al-Mg)

Li-ingots tsa poleiti: 500～1000kg (bakeng sa tlhahiso ea poleiti)

Li-ingots tse pota-potileng: 30 ~ 60kg (bakeng sa ho taka ka terata)

III.Mokhoa oa ho Lahlela Aluminium Ingot

Aluminium tapping—Ho tlosa lerole—Tlhahlobo ea boima ba ’mele—Ho tsoakoa ha thepa—Ho kenya sebōpi—Ho hloekisa—Ho Lahlela—Ho qhibilihisa li-ingots—Tekolo ea ho qetela—Tlhahlobo ea ho qetela ea boima—Bobolokelo.

Aluminium tapping—Ho tlosa lerela—Tlhahlobo ea boima ba ’mele—Ho tsoaka lintho tse bonahalang—Ho kenya sebōpi—Ho hloekisa—Ho Rala—Li-ingots tsa motsoako—Tlhahlobo ea ho qetela—Tlhahlobo ea ho qetela ea boima—Bobolokelo.

IV.Mokhoa oa ho Lahlela

Mokhoa oa hona joale oa ho lahla aluminium ka kakaretso o sebelisa mokhoa oa ho tšela, moo mokelikeli oa aluminium o tšeloang ka ho toba ka har'a hlobo ebe o lumelloa ho pholile pele o ntšoa.Boleng ba sehlahisoa bo khethoa haholo-holo mohatong ona, 'me mokhoa oohle oa ho lahla o pota-potile mohato ona.Casting ke mokhoa oa 'mele oa ho pholisa aluminiamo ea mokelikeli le ho e khantša ka li-ingots tse tiileng tsa aluminium.

1. Tsoelo-pele ea ho Lahla

Ho lahla ho tsoelang pele ho kenyelletsa mekhoa e 'meli: ho lahla sebōpi se tsoakiloeng le ho lahlela ka ntle, ka bobeli ba sebelisa mechine e tsoelang pele ea ho lahla.Motsoako oa sebōpi o kenyelletsa ho tšela mokelikeli oa aluminium ka har'a sebōpi se tsoakiloeng bakeng sa ho lahlela 'me o sebelisoa haholo-holo bakeng sa ho hlahisa li-ingots tse remelting le li-alloy ingots.Ho lahla ka ntle ho phalla ka ho toba ho tloha ho crucible ho ea mochine oa ho lahla 'me ho sebelisoa ha thepa ea ho lahla e sitoa ho finyella litlhoko tsa tlhahiso kapa ha boleng ba thepa bo kenang bo fokola.

2. Mohaho oa Semi-Continuous Casting

Ho lahla ho sa feleng ho sebelisoa haholo ho hlahisa li-ingots tsa terata ea aluminium, li-ingots tsa poleiti, le li-alloys tse fapaneng tsa deformation bakeng sa ho sebetsa.Ka mor'a ho kopanya thepa, mokelikeli oa aluminium o tšeloa ka sebōping se tsoakiloeng.Bakeng sa li-ingots tsa terata, ho eketsoa diski e khethehileng ea Al-B ho tlosa titanium le vanadium ho tsoa mokelikeli oa aluminium pele o lahla.Boleng ba bokaholimo ba li-ingots tsa terata ea aluminium bo lokela ho ba boreleli ntle le slag, mapetsong, kapa masoba a khase.Ho phatloha ha sefahleho ha hoa lokela ho ba nako e telele ho feta 1.5mm, li-slag le li-wrinkles tse bohale ha lia lokela ho feta 2mm ka botebo, 'me karolo ea sefapano e lokela ho lokoloha ho tloha mapetsong, li-pores tsa khase,' me li se ke tsa feta 5 slag inclusions tse nyenyane ho feta 1mm. Bakeng sa li-ingots tsa poleiti, motsoako oa Al-Ti-B (Ti5% B1%) o eketsoa bakeng sa ntlafatso.Joale li-ingots lia pholisoe, li ntšoe, li sakha ka boholo bo hlokahalang, ebe li lokisetsoa potoloho e latelang ea ho akhela.
