Thealuminium ndariraakateedzana akanyanya kuomarara, uye mamwe eakaomeswa aluminium ndarira ane yechitatu neyechina alloying zvinhu zvakaita se manganese, nickel, silicon, cobalt uye arsenic.HAl66-6-3-2 uye HAl61-4-3-1, ane zvimwe alloying zvinhu, alloys anoumbwa zvinhu zvitanhatu, uye mamwe acho akaoma-akagadziridzwa aruminiyamu ndarira kubva inokosha-shaped kukanda alloys.Akasiyana alloys anowanzo kuve akasiyana ekunyunguduka uye nekudaro anoda akasiyana maitiro ekunyunguduka.
Chokutanga pane zvose, ndarira yealuminium iri nyore "kupupuma" panguva yekunyunguduka uye inosvibiswa nyore nyore nealuminium kana imwe simbi oxide inclusions.Nzira inonzwisisika yekunyungudutsa inofanira kusanganisira mamwe maitiro ekudzivirira.Kana pane oxide firimu yealuminium pamusoro pekunyunguduka, inogona kudzivirira kunyunguduka kune imwe nhanho, uye hazvidiwi kuwedzera chivharo chekuvhara panguva yekunyunguduka.
Theoretical analysis: Kana uchiwedzera zinc kune yakanyungudutswa dziva rakachengetedzwa neAl2O3 firimu, kuparara kwekuparara kwezinc kunogona kuderedzwa.Muchokwadi, sezvo kubikira kwe zinc kunogona kukuvadza iyo oxide firimu, chete kana yakafanira flux inoshandiswa, ndiko kuti, kunyunguduka kunogona kuchengetedzwa zvakanyanya, kupisa kwekupisa kwe zinc kunogona kudziviswa zvinobudirira kana kuderedzwa.Cryolite yave chinhu chakakosha uye chakakosha chikamu mukuyerera kunoshandiswa kunyungudutsa aluminium ndarira.Iyo aruminiyamu-ndarira inonyunguduka haifanirwe kuve yakanyanyisa kupisa kudzivirira kunyungudika kubva kune oxidizing uye kufema zvakanyanya.Kana iyo gasi yemukati mukunyunguduka yakakwira zvakanyanya, unogona kusarudza flux kufukidzwa kwekunatsa, kana kushandisa inert gasi refine, kusanganisira re-fluxing uye kudzokorora kunatsa usati wadururwa, uye kushandisa bhero chirongo kudzvanya chloride munyu munyungudika yekunyungudika kunatsa Nzira.Iyo yakakwira melting point alloy zvinhu zvakaita sesimbi, manganese, silicon, nezvimwewo zviri muakaomeswa aluminium brass inofanira kuwedzerwa muchimiro cheCu-Fe, Cu-Mn uye mamwe epakati alloys.
Kazhinji, yakawanda inoshandiswa kubhadharisa uye mhangura inofanira kuwedzerwa muchoto kutanga uye yakanyungudutswa, mutero wakakamurwa zvakanaka unogona kuwedzerwa zvakananga pakunyunguduka, uye zinc inowedzerwa pakupedzisira pakupera kwekunyunguduka.Kana simbi dzakachena dzichishandiswa sekuchajisa, dzinofanirwa kuve deoxidized ne phosphorus mushure mekunyungudika, ichiteverwa nemanganese (Cu-Mn), iron (Cu-Fe), ipapo aluminium, uye pakupedzisira zingi.Mune yakaoma aluminium brass HAl66-6-3-2, iyo iron yemukati inofanirwa kudzorwa pa2% ~ 3%, uye manganese emukati anofanirwa kudzorwa paanenge 3%.Zvikasadaro, kana zvirimo zvakawandisa, zvimwe zvinhu zvealloy zvinogona kukanganiswa.Nekuda kwekushomeka kwealuminium, kana iyo yakanyunguduka isina kunyatsomutswa, inogona kukonzera kusaenzana kwemakemikari kuumbwa.Kana paine shanduko yekunyungudika muchoto, kazhinji aruminiyamu uye chikamu chemhangura chinogona kutanga chawedzerwa, uyezve zinc inogona kuwedzerwa mushure mekunge yanyungudutswa.Kana aruminiyamu yawedzerwa, huwandu hukuru hwekupisa hunogona kuburitswa nekuda kwekusanganiswa kwemhangura nealuminium.Iyo exothermic process inogona kushandiswa kukurumidzira kunyunguduka, asi kana oparesheni isina kuitwa nemazvo, iyo yakanyanya exothermic reaction inogona kuita kuti tembiricha yemunzvimbo yedziva yakanyungudutswa iwedzere zvakanyanya, zvichikonzera kuvhuvhuta kwechisimba kwe zinc, uye mumatambudziko akaomarara, marimi anogona kuburitswa kubva muchoto.Iyo tembiricha yekunyungudutsa HAl67-2.5 inowanzo 1000 ~ 1100 ℃, uye tembiricha yekunyungudutsa HAl60-1-1, HAl59-3-2, HAl66-6-6-2 inowanzo 1080 ~ 1120 ℃, uye tembiricha yakaderera inofanira kushandiswa zvakanyanya sezvinobvira.Kunyunguduka tembiricha.
