Aluminium alloy yakashandiswa zvakanyanya mundege, mota, kuvaka uye mamwe minda nekuda kwehuremu hwayo huremu, kusimba kwepamusoro, kushomeka kwemarara uye zvimwe zvivakwa. 6063 aruminiyamu alloy, senhengo yemhuri yealuminium-magnesium-silicon (Al-Mg-Si) inoshandiswa zvakanyanya mukuvaka, kutakurisa, zvemagetsi nemamwe minda nekuda kwekuita kwayo kwakanakisa kwekugadzirisa uye mashandiro emagetsi. Chinyorwa ichi chichatarisa mukunyunguduka nekukanda maitiro e6063 aruminiyamu alloy, ongorora kukosha kwekutonga kuumbwa, uye kusuma zvakadzama makiyi ehunyanzvi ekubatanidza senge kunyungudutsa, kukanda uye homogenization kurapwa.
Kukosha kwealuminium alloy composition control
Kuumbwa kwekutonga kwealuminium alloys ndiyo kiyi yekuve nechokwadi chekushanda kwezvinhu. Mukugadzirwa kwe6063 aruminiyamu alloy, kunze kwekudzora zviri mukati meiyo main alloy element, senge reshiyo yemagnesium nesilicon, kusachena zvinhu zvakaita sesimbi, mhangura, manganese, nezvimwewo zvinodawo kunyatsodzorwa. Kunyangwe zvinhu izvi zviine zvishoma pazvimiro zvealloy muhuwandu hwekutevera, kana zvangodarika imwe muganho, zvinokanganisa zvakanyanya ma mechanic zvivakwa uye corrosion kuramba kwechinhu. Kunyanya zinc, kana zvirimo zvichipfuura 0.05%, mavara machena achaonekwa pamusoro peiyo profil mushure meoxidation, saka kutonga kwe zinc zvirimo kunonyanya kukosha.
Basic maitiro eAl-Mg-Si aluminium alloy
Kemikari ye6063 aluminium alloy inobva paGB / T5237-93 chiyero, iyo inonyanya kusanganisira 0.2-0.6% silicon, 0.45-0.9% magnesium uye kusvika 0.35% iron. Iyi alloy ndiyo inopisa-inogadziriswa yakasimbiswa aluminium alloy, uye chikamu chayo chikuru chekusimbisa iMg2Si. Munguva yekudzima, huwandu hwemhinduro yakasimba Mg2Si inosarudza simba rekupedzisira reiyo alloy. Eutectic tembiricha i595°C. Panguva ino, iyo yakanyanya solubility yeMg2Si ndeye 1.85%, iyo inodonha kusvika 1.05% pa500 ° C. Izvi zvinoratidza kuti kutonga kwekudzima tembiricha kwakakosha kusimba reiyo alloy. Pamusoro pezvo, chiyero che magnesium kune silicon mune alloy ine mhedzisiro yakakosha pakunyungudika kwakasimba kweMg2Si. Kuti uwane alloy yakakwirira-simba, zvakakosha kuve nechokwadi kuti chiyero cheMg: Si chiri pasi pe1.73.
Kunyungudutsa tekinoroji ye6063 aluminium alloy
Kunyungudutsa ndiro danho rekutanga mukugadzira matanda emhando yepamusoro. Tembiricha yekunyunguduka ye6063 aruminiyamu alloy inofanira kunyatsodzorwa pakati pe750-760°C. Kunyanya kuderera tembiricha inotungamira kune chizvarwa che slag inclusions, nepo tembiricha yakanyanya kunowedzera njodzi yekutorwa kwehydrogen, oxidation uye nitriding. Kunyungudika kwehydrogen muaruminiyamu yemvura inokwira zvakanyanya kupfuura 760°C. Naizvozvo, kudzora tembiricha yekunyungudika ndiyo kiyi yekudzikisa kunyura kwehydrogen. Pamusoro pezvo, kusarudzwa kwekuyerera uye kushandiswa kwehunyanzvi hwekunatsa kwakakoshawo. Iwo anoyerera parizvino ari pamusika akanyanya chloride uye fluoride. Izvi zvinoyerera zviri nyore kutora unyoro. Naizvozvo, zvigadzirwa zvinofanirwa kuchengetwa zvakawoma panguva yekugadzirwa, kuvharwa nekuiswa mukati uye kuchengetwa nemazvo. Powder spray refining ndiyo nzira huru yekunatsa 6063 aluminium alloy. Kuburikidza nenzira iyi, mumiriri wekunatsa anogona kunyatsobatana nealuminium liquid kuti iwedzere kushanda kwayo. Iyo nitrogen pressure inoshandiswa mukunatsa hupfu inofanira kunge yakaderera sezvinobvira kuderedza dambudziko re oxidation uye hydrogen absorption.
Kukandira tekinoroji ye6063 aluminium alloy
Kukandira inhanho yakakosha pakuona kunaka kwematanda ekukanda. Tembiricha yekukanda inonzwisisika inogona kudzivirira kuitika kwekukanganisa kwekukanda. Kune 6063 aruminiyamu alloy fluid yakagadziriswa zviyo zvekunatswa, tembiricha yekukanda inogona kuwedzerwa zvakakodzera kusvika 720-740 ° C. Iyi tembiricha yemhando inoenderana nekuyerera uye kusimba kwealuminium yemvura uku ichideredza njodzi yemapores uye coarse zviyo. Munguva yekukanda, mhirizhonga uye kutenderera kwealuminium liquid inofanira kudziviswa kudzivirira kuputika kweiyo oxide film uye chizvarwa che slag inclusions. Mukuwedzera, kusefa iyo aluminium liquid inzira inoshanda yekubvisa isiri-metallic slag. Izvo zvinofanirwa kuve nechokwadi kuti iyo yepamusoro scum yealuminium fluid inobviswa isati yasefa kuti ive nechokwadi chekusefa.
Homogenization kurapwa kwe6063 aluminium alloy
Homogenization kurapwa inzira yakakosha yekupisa kupisa kubvisa kukanda kushushikana uye kusaenzana kwemakemikari mukati mezviyo. Non-equilibrium crystallization inotungamira mukukanda kushushikana uye kusaenzana kwemakemikari pakati pezviyo. Aya matambudziko achakanganisa kufambira mberi kwakatsetseka kweiyo extrusion process, pamwe neiyo mechanical properties uye pamusoro pekugadzirisa zvinhu zvechigadzirwa chekupedzisira. Iyo homogenization kurapwa inokurudzira kupararira kwealuminium alloy zvinhu kubva kumiganhu yezviyo kusvika muzviyo nekuchengetedza kupisa pakupisa kwakanyanya, nokudaro kuwana uniformization yemakemikari emukati mukati mezviyo. Ukuru hwezviyo hune simba guru panguva yekurapa homogenization. Iyo yakanakisa zviyo, iyo ipfupi nguva yehomogenization. Kuti uderedze mutengo wehomogenization kurapwa, matanho akadai sekunatswa kwezviyo uye optimization yekudziya yevira remoto segmentation control inogona kutorwa.
Mhedziso
Kugadzirwa kwe6063 aruminiyamu alloy inzira yakaoma inosanganisira kudzora kuumbwa, kunyungudika kwakaoma uye tekinoroji yekukanda, uye yakakosha homogenization kugadzirisa. Nekunyatsofunga nekudzora zvinhu izvi zvakakosha, yakakwirira-mhando yealuminium alloy cast rods inogona kugadzirwa, ichipa hwaro hwezvinhu hwakasimba hwekuzotevera kugadzirwa kweprofile. Nekufambira mberi kwesainzi uye tekinoroji uye optimization yemaitiro, kugadzirwa kwearuminiyamu alloys kuchave kwakanyatso shanda uye kune hushamwari kwezvakatipoteredza, zvichiita mipiro yakakura mukusimudzira indasitiri yemazuva ano.
