1 Nhanganyaya
Nekukurumidza kusimudzira kweindasitiri yealuminium uye nekuenderera mberi kwekuwedzera kwetonnage yealuminium extrusion michina, tekinoroji yeporous mold aluminium extrusion yabuda. Porous mold aluminium extrusion inovandudza zvakanyanya kugadzirwa kweextrusion uye inoisa yakakwira tekinoroji zvinodiwa pakugadzira mold uye extrusion maitiro.
2 Extrusion Process
Iko kukanganiswa kweiyo extrusion maitiro pakugadzira kugona kweporous mold aluminium extrusion inonyanya kuratidzwa mukutonga kwezvinhu zvitatu: tembiricha isina chinhu, tembiricha yekuumbwa, uye tembiricha yekubuda.
2.1 Blank Temperature
Uniform blank tembiricha ine yakakosha kukanganisa pane extrusion inobuda. Mukugadzira chaiko, michina yeextrusion inotaridza kushanduka kwepasi inowanzo kupiswa uchishandisa mavira-asina chinhu. Multi-blank furnaces inopa yakawanda yunifomu uye yakakwana isina blank kudziyisa ine yakanaka yekudzivirira zvivakwa. Pamusoro pezvo, kuitira kuve nechokwadi chekushanda kwepamusoro, iyo "yakaderera tembiricha uye yakanyanya kumhanya" nzira inowanzo shandiswa. Muchiitiko ichi, tembiricha isina chinhu uye tembiricha yekubuda inofanira kunyatsoenderana nekumhanya kweextrusion, nezvigadziriso zvichifunga nezvekuchinja kweextrusion pressure uye mamiriro enzvimbo isina chinhu. Maseti etembiricha asina kujeka anoenderana nemamiriro chaiwo ekugadzira, asi segwara regwara, kune porous mold extrusion, tembiricha isina chinhu inowanzo chengetwa pakati pe420-450 ° C, neflat inofa ichiiswa yakakwira zvishoma ne10-20 ° C zvichienzaniswa nekupatsanurwa kunofa.
2.2 Mold Temperature
Zvichienderana neruzivo rwekugadzira-saiti, tembiricha yekuumbwa inofanirwa kuchengetedzwa pakati pe420-450°C. Kunyanya kupisa nguva kunogona kutungamirira mukukukurwa kwe mold panguva yekushanda. Uyezve, kuisa mold yakakodzera panguva yekupisa kwakakosha. Iyo mold haifanirwe kusungirirwa padhuze pamwe chete, ichisiya imwe nzvimbo pakati pavo. Kuvharira kubuda kwemhepo kwechoto chekuumbwa kana kuiswa zvisina kufanira kunogona kutungamirira mukupisa kusina kuenzana uye kusingawirirani extrusion.
3 Mold Factors
Dhizaini yeMold, kugadzirisa mold, uye kugadzirisa mold kwakakosha pakuumbwa kweextrusion uye kunokanganisa zvakananga chigadzirwa chepamusoro mhando, kurongeka, uye kugona kugadzira. Kudhirowa kubva kumaitiro ekugadzira uye kugovera mold dhizaini zviitiko, ngationgororei aya maficha.
3.1 Mold Dhizaini
Mould ndiyo hwaro hwekuumbwa kwechigadzirwa uye inoita basa rakakosha pakuona chimiro, kurongeka kwedimensional, kunaka kwepamusoro, uye zvinhu zvechigadzirwa. Kune porous mold profiles ine yakakwirira yepamusoro zvinodiwa, kuvandudza pamusoro pemhando inogona kuwanikwa nekudzikisa huwandu hwegomba rekutsaudzira uye nekugadzirisa kuiswa kwemabhiriji ekutsaudzira kudzivirira iyo huru yekushongedza nzvimbo yeprofile. Pamusoro pezvo, kune flat inofa, kushandisa reverse kuyerera gomba dhizaini kunogona kuve nechokwadi chekuyerera kwesimbi mumakomba anofa.
3.2 Mold Processing
Munguva yekugadzira mold, kuderedza kuramba kuyerera kwesimbi pamabhiriji kwakakosha. Kugaya mabhiriji ekutsaudzira zvakanaka kunovimbisa huchokwadi hwenzvimbo dzebhiriji rekutsauka uye kunobatsira kuwana yunifomu yesimbi kuyerera. Kune maprofiles ane epamusoro emhando yepamusoro zvinodiwa, senge solar panels, funga kuwedzera hurefu hwekamuri yewelding kana kushandisa yechipiri welding process kuti uve nechokwadi chezvakanaka welding.
3.3 Kuchengetedza Mold
Nguva dzose kugadzirisa mold kwakakosha zvakaenzana. Kuchenesa zviumbwa uye kushandisa nitrogenization kugadzirisa kunogona kudzivirira nyaya dzakadai sekuoma kusina kuenzana munzvimbo dzekushanda dzezviumbwa.
4 Hunhu Husina chinhu
Hunhu hwekushaikwa hune hunhu hwakakosha pamhando yechigadzirwa, kugona kweextrusion, uye kukuvadzwa kwekuumbwa. Yakashata-yemhando blanks inogona kutungamira kumatambudziko emhando senge grooves, discoloration mushure me oxidation, uye kuderedzwa hupenyu hwekuumbwa. Hunhu husina chinhu hunosanganisira kuumbwa kwakaringana uye kufanana kwezvinhu, zvese zviri zviviri zvinokanganisa kubuda kweextrusion uye kunaka kwepamusoro.
4.1 Magadzirirwo ekuumbwa
Kutora solar panel profiles semuenzaniso, kumisikidzwa kwakaringana kweSi, Mg, uye Fe mune yakasarudzika 6063 alloy yeporous mold extrusion yakakosha kuti uwane yakanakisa yemhando yepamusoro pasina kukanganisa michina. Huwandu hwese uye chikamu cheSi neMg chakakosha, uye zvichibva pachiitiko chenguva refu chekugadzira, kuchengetedza Si + Mg muhuwandu hwe0.82-0.90% kwakakodzera kuwana inodiwa yemhando yepamusoro.
Mukuongororwa kwezvisina-kupindirana zvivharo zvemagetsi ezuva, zvakaonekwa kuti kutsvaga zvinhu uye tsvina zvakanga zvisina kugadzikana kana kudarika miganhu, zvakanyanya kukanganisa kunaka kwepamusoro. Kuwedzerwa kwezvinhu panguva yekusanganiswa muchitoro chekunyungudika kunofanirwa kuitwa nekuchenjerera kudzivirira kusagadzikana kana kuwanda kwezvinhu zvekutevera. Muchikamu chemarara eindastiri, marara ekuwedzera anosanganisira marara ekutanga senge-kuchekwa-chekwa uye zvigadziko, tsvina yechipiri inosanganisira post-kugadzirisa tsvina kubva kumabasa akaita seoxidation uye poda coating, uye mafiritsi ekudzivirira anoiswa muzvikamu semarara epamusoro. Oxidized profiles anofanirwa kushandisa yakakosha isina chinhu, uye kazhinji hapana tsvina ichawedzerwa kana zvinhu zvakwana.
4.2 Chisina Kugadzira Maitiro
Kuti uwane zvivharo zvemhando yepamusoro, kuomerera kune zvinodikanwa zve nitrogen yekuchenesa nguva uye nguva yekumisikidza aluminium kwakakosha. Alloying zvinhu zvinowanzowedzerwa mu block form, uye kunyatso kusanganisa kunoshandiswa kukurumidza kupera kwavo. Kusanganiswa kwakakodzera kunodzivirira kuumbwa kwenzvimbo dzakakwirira-concentration zones ye alloy elements.
Mhedziso
Aluminium alloys anoshandiswa zvakanyanya mumotokari nyowani dzesimba, aine maapplication muzvikamu zvezvimiro uye zvikamu zvakaita semuviri, injini, uye mavhiri. Kuwedzera kwekushandiswa kwealuminium alloys muindasitiri yemotokari kunofambiswa nekudiwa kwesimba rekushandisa uye kuchengetedza kwezvakatipoteredza, zvakasanganiswa nekufambira mberi mualuminium alloy tekinoroji. Kune maprofile ane epamusoro emhando yepamusoro zvinodiwa, senge aruminiyamu bhatiri matireyi ane akawanda maburi emukati uye akakwira mechanika kuita zvinodiwa, kuvandudza kushanda kweporous mold extrusion kwakakosha kuti makambani abudirire mumamiriro ekushandurwa kwesimba.
