Kudzora kwakanaka kwemaitiro ekunyungudutsa uye kukanda aruminiyamu: ongororo yakazara ye6063 aruminiyamu alloy sumo.

Kudzora kuumbwa kwearuminiyamu alloys ndicho chinhu chikuru chekuona kuti zvinhu zvinoshanda. Mukugadzirwa kwearuminiyamu alloy ye6063, pamusoro pekudzora huwandu hwezvinhu zvikuru zvealloy, zvakaita sehuwandu hwemagnesium nesilicon, zvinhu zvisina kuchena zvakaita sesimbi, mhangura, manganese, nezvimwewo zvinodawo kudzorwa zvakasimba. Kunyangwe zvinhu izvi zvisingabatsiri zvakanyanya pahunhu hwealloy muhuwandu hushoma, kana zvapfuura muganho wakati, zvichakanganisa zvakanyanya hunhu hwemakanika uye kuramba ngura kwezvinhu. Kunyanya zinc, kana huwandu hwayo huchidarika 0.05%, mavara machena achaonekwa pamusoro peprofile mushure mekuoxidation, saka kudzora huwandu hwezinc kwakakosha zvikuru.

Kuumbwa kwemakemikari e6063 aruminiyamu alloy kwakavakirwa paGB/T5237-93 standard, iyo inonyanya kusanganisira 0.2-0.6% silicon, 0.45-0.9% magnesium uye kusvika 0.35% iron. Iyi alloy ialuminium alloy yakasimbiswa inogona kurapwa nekupisa, uye chikamu chayo chikuru chekusimbisa iMg2Si. Munguva yekudzima, huwandu hweMg2Si yakasimba ndiyo inosarudza simba rekupedzisira realloy. Tembiricha ye eutectic i595°C. Panguva ino, kunyungudika kwakanyanya kweMg2Si i1.85%, iyo inodonha kusvika 1.05% pa500°C. Izvi zvinoratidza kuti kudzora tembiricha yekudzima kwakakosha kusimba realloy. Pamusoro pezvo, chiyero chemagnesium nesilicon mualloy chine simba guru pakunyungudika kwakasimba kweMg2Si. Kuti uwane alloy yakasimba, zvakakosha kuve nechokwadi chekuti chiyero cheMg:Si chiri pasi pe1.73.

Kunyungudutsa ndiyo danho guru mukugadzira tsvimbo dzemhando yepamusoro. Kunyunguduka kwe6063 aluminum alloy kunofanirwa kudzorwa zvakasimba pakati pe750-760°C. Kupisa kwakaderera zvakanyanya kunotungamira mukugadzirwa kweslag inclusions, nepo tembiricha yakakwira zvakanyanya inowedzera njodzi yekunyunguduka kwehydrogen, oxidation uye nitriding. Kunyunguduka kwehydrogen mu liquid aluminum kunokwira zvakanyanya pamusoro pe760°C. Naizvozvo, kudzora tembiricha yekunyunguduka ndiyo kiyi yekuderedza kunyunguduka kwehydrogen. Pamusoro pezvo, kusarudzwa kweflux uye kushandiswa kwetekinoroji yekunatsa kwakakoshawo. Maflux ari pamusika parizvino anonyanya kuve chloride nefluoride. Maflux aya anonwisa hunyoro nyore nyore. Naizvozvo, zvinhu zvakagadziriswa zvinofanirwa kuchengetwa zvakaoma panguva yekugadzira, zvakavharwa uye zvakarongedzwa uye zvakachengetedzwa zvakanaka. Kunatsa kwepoda ndiyo nzira huru yekuchenesa 6063 aluminum alloy. Kuburikidza nenzira iyi, refining agent inogona kubata zvizere nealuminium liquid kuti iwedzere kushanda kwayo. nitrogen pressure inoshandiswa mukuchenesa poda inofanira kunge yakaderera sezvinobvira kuderedza njodzi yekunyunguduka uye kunyunguduka kwehydrogen.

Kukanda simbi idanho guru pakuona mhando yematanda akaumbwa. Kupisa kwakagadzikana kwesimbi kunogona kudzivirira kuitika kwezvikanganiso zvesimbi. Kune mvura yealuminium 6063 yakagadziriswa simbi, tembiricha yesimbi inogona kuwedzerwa kusvika 720-740°C. Kupisa uku kunobatsira kuti simbi yealuminium irambe ichiyerera uye ichioma ukuwo ichideredza njodzi yemaburi nemarara. Munguva yekukanda, kutenderera nekumonereka kwesimbi yealuminium kunofanirwa kudzivirirwa kudzivirira kuputika kwefirimu reoxide uye kugadzirwa kwesimbi inclusions. Pamusoro pezvo, kusefa simbi yealuminium inzira inoshanda yekubvisa tsvina isiri yesimbi. Inofanira kuve nechokwadi chekuti tsvina yesimbi yesimbi yealuminium inobviswa isati yasefa kuti ive nechokwadi chekuti yakapfava.

Kurapa kwehomogenization inzira yakakosha yekurapa kupisa kubvisa kushushikana kwekukanda uye kusawirirana kwemakemikari mukati mezviyo. Kusaenzana kwemakristaro kunotungamira mukukanganiswa kwemashizha uye kusawirirana kwemakemikari pakati pezviyo. Matambudziko aya achakanganisa kufambira mberi kwakanaka kwemaitiro ekubvisa, pamwe chete nehunyanzvi hwemakanika uye hunhu hwekugadzirisa pamusoro pechigadzirwa chekupedzisira. Kurapa kwehomogenization kunokurudzira kupararira kwezvinhu zvealuminium alloy kubva kumiganhu yezviyo kuenda kuzviyo nekuchengetedza kupisa pakupisa kwakanyanya, nokudaro zvichiita kuti kuve nekuenzana kwemakemikari mukati mezviyo. Saizi yezviyo ine simba guru panguva yekurapa homogenization. Zviyo zvikapfava, nguva yehomogenization ipfupi. Kuti kuderedzwa mutengo wekurapa homogenization, matanho akadai sekunatswa kwezviyo uye kugadzirisa kudzora kwekudzikisa chitofu chekupisa kunogona kutorwa.

Kugadzirwa kwe6063 aruminiyamu alloy inzira yakaoma inosanganisira kudzora kwakasimba kwekuumbwa kwayo, tekinoroji yekunyungudutsa nekukanda zvinhu, uye kugadzirisa kwakakosha kwe homogenization. Nekufunga zvakakwana uye kudzora zvinhu izvi zvakakosha, tsvimbo dzemhando yepamusoro dzearuminiyamu alloy dzinogona kugadzirwa, zvichipa hwaro hwakasimba hwekugadzirwa kweprofile inotevera. Nekufambira mberi kwesainzi netekinoroji uye kugadzirisa mashandiro, kugadzirwa kwearuminiyamu alloys kuchave kwakanyatsoshanda uye kusina njodzi kune zvakatipoteredza, zvichipa mipiro yakakura mukusimudzira indasitiri yemazuva ano.
