Mhedziso yeAluminium Ingot Casting process

I. Nhanganyaya

Hunhu hwekutanga aluminium inogadzirwa mualuminium electrolytic maseru inosiyana zvakanyanya, uye ine akasiyana simbi tsvina, magasi, uye isiri-simbi yakasimba inclusions. Basa realuminium ingot casting nderekuvandudza mashandisirwo emvura yakaderera-giredhi yealuminium uye kubvisa tsvina zvakanyanya sezvinobvira.

II. Kurongwa kweAluminium Ingots

Aluminium ingots akaiswa mumhando nhatu zvichienderana nekuumbwa: remelting ingots, high-purity aluminium ingots, uye aluminium alloy ingots. Iwo anogona zvakare kuiswa muchikamu nechimiro uye saizi, senge slab ingots, round ingots, plate ingots, uye T-yakaumbwa ingots. Pazasi pane akati wandei akajairika marudzi ealuminium ingots:

Kugadzirisa ingots: 15kg, 20kg (≤99.80% Al)

Ingots dzakaumbwa neT: 500kg, 1000kg (≤99.80% Al)

Yakakwirira-kuchena aluminium ingots: 10kg, 15kg (99.90% ~ 99.999% Al)

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

Plate ingots: 500～1000kg (yekugadzira ndiro)

Round ingots: 30 ~ 60kg (yekudhirowa waya)

III. Aluminium Ingot Casting Process

Aluminium kubaya—Kubvisa tsvina—Kuongorora huremu—Kusanganiswa kwezvinhu—Kuisa choto—Kunatsa—Kukanda—Kunonyungudutsa ingots—Kuongorora kwokupedzisira—Kuongorora huremu hwekupedzisira—Kuchengeta.

Aruminiyamu kubaya—Kubvisa tsvina—Kuongorora huremu—Kusanganisa zvinhu—Kuisa muchoto—Kunatsa—Kukanda—Ingotsi dzearuminiyamu—Kukanda alloy ingots—Kuongorora kwekupedzisira—Kuongorora huremu hwekupedzisira—Kuchengeta.

IV. Casting Process

Ikozvino aluminium ingot casting process inowanzo shandisa nzira yekudira, apo mvura yealuminium inodururwa yakananga mumold uye inobvumidzwa kutonhora isati yabviswa. Hunhu hwechigadzirwa hunonyanya kutsanangurwa padanho iri, uye iyo yese yekukanda maitiro inotenderera ichi chikamu. Kukandira ndiyo yemuviri maitiro ekutonhodza mvura aruminiyamu uye nekuipenya kuita yakasimba aruminiyamu ingots.

1. Kuenderera mberi Kukandira

Kuramba kuchikanda kunosanganisira nzira mbiri: yakasanganiswa yevira yekukandira uye yekunze kukanda, zvese uchishandisa inoenderera mberi yekukanda michina. Muvhenganiswa wekukandwa kwevira kunosanganisira kudururira mvura yealuminium muchoto chakavhenganiswa chekukandira uye inonyanya kushandiswa kugadzira ingots uye alloy ingots. Kukandira kwekunze kunodururwa zvakananga kubva kucrucible kuenda kumuchina wekukanda uye kunoshandiswa kana iyo yekukanda isingakwanise kuzadzisa zvinodiwa zvekugadzira kana kana zvinhu zvinouya zviine hurombo.

2. Vertical Semi-Continuous Casting

Vertical semi-inoenderera mberi kukanda kunonyanya kushandiswa kugadzira aluminium waya ingots, ingots yeplate, uye akasiyana deformation alloys ekugadziriswa. Mushure mekusanganiswa kwezvinhu, mvura yealuminium inodururwa muchoto chakasanganiswa. Kune ingots dzewaya, yakakosha Al-B disc inowedzerwa kubvisa titanium uye vanadium kubva mualuminium mvura isati yakanda. Pamusoro pemhando yealuminium waya ingots inofanirwa kuve yakatsetseka isina slag, kuputika, kana gasi pores. Kuputika kwepamusoro hakufaniri kunge kwakareba kupfuura 1.5mm, slag uye kumucheto wrinkles haifaniri kudarika 2mm pakadzika, uye chikamu chemuchinjikwa chinofanira kunge chisina kuputika, gasi pores, uye kwete kupfuura 5 slag inclusions duku kudarika 1mm. Nokuti plate ingots, Al-Ti-B alloy (Ti5% B1%) inowedzerwa kunatswa. Ingots dzinobva dzatonhodzwa, dzobviswa, dzochekwa kusvika pazviyero zvinodiwa, uye dzogadzirirwa kutenderera kunotevera.
