Tam sim no, kev thov rau txhuas profile txuas ntxiv nce hauv kev tsim kho, kev tsim khoom lag luam, lub zog hluav taws xob tshiab, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob photovoltaic thiab lwm yam. Raws li cov qib tseem ceeb rau extruded profiles, 6063-T5 thiab 6061-T6 feature cov tshuaj muaj pes tsawg leeg tswj, uas ncaj qha tswj extrudability, anodizing nto zoo, txhua yam muaj zog, corrosion kuj thiab batch sib xws. Nws ua haujlwm raws li thawj qhov kev tswj xyuas zoo rau txhuas profile manufacturers thiab OEM / ODM kev txiav txim txawv teb chaws, ua raws li GB / T 3190-2020Chemical Composition ntawm Wrought Aluminium thiab Aluminium Alloys.
Aluminium profiles yog raws li txhuas (Al), suav txog ntau dua 97% ntawm tag nrho cov khoom. Alloying ntsiab feem ntau suav nrog silicon thiab magnesium, ntxiv los ntawm tooj liab, manganese, chromium, zinc, titanium thiab lwm yam kab kawm. Hlau yog ib qho kev impurity nrog kev txwv nruj. Hnub nyoog hardening yog ua tiav los ntawm Mg₂Si ntxiv dag zog rau theem, cov ntsiab lus tseem ceeb ntawm 6XXX-series Al-Mg-Si alloys.
Cov txheej txheem tshuaj muaj pes tsawg leeg ntawm ob qib tseem ceeb tau teev tseg hauv qab no:6063 Alloy (qib thawj zaug rau architectural profiles, hniav profiles, cua sov dab dej thiab hniav trim strips):Si: 0.20% ~ 0.60%, Mg: 0.45% ~ 0.90%; Impurity Fe Tsawg dua lossis sib npaug 0.35%, Cu Tsawg dua lossis sib npaug 0.10%, Mn Tsawg dua lossis sib npaug 0.10%, Zn Tsawg dua lossis sib npaug 0.10%, Ti Tsawg dua lossis sib npaug 0.10%. Ib qho residual impurity Tsawg dua los yog sib npaug rau 0.05%, tag nrho cov khoom seem seem tsawg dua lossis sib npaug li 0.15%. Cov mis no xa cov extrusion fluidity zoo heev thiab tsis tshua muaj extrusion siab, nrog cov yeeb yaj kiab zoo li qub thiab ci ntsa iab anodized. Nws yog tsim rau complex nyias-walled hniav profiles thiab nto-tiav cov khoom, thiab yog cov feem ntau lug siv qib rau hniav zoo nkauj txhuas profiles exported txawv teb chaws.
6061 Alloy (rau cov khoom siv hauv tsev, cov khoom siv ntim khoom, cov kabmob thauj khoom thiab CNC machined profiles):Si: 0.40% ~ 0.80%, Mg: 0.80% ~ 1.20%, Cu: 0.15% ~ 0.40%, Cr: 0.04% ~ 0.35%; Impurity Fe Tsawg dua los yog sib npaug rau 0.70%, Mn Tsawg dua lossis sib npaug rau 0.15%, Zn Tsawg dua lossis sib npaug li 0.25%. Piv nrog rau 6063, siab dua magnesium & silicon cov ntsiab lus ntxiv rau micro-alloying nrog tooj liab thiab chromium zoo heev txhim kho tensile lub zog thiab tawm los lub zog, ua rau nws zoo tagnrho rau load-bearing lug thiab machined industrial Cheebtsam. Cov downsides muaj xws li extrusion nyuaj dua thiab tsis muaj zog anodizing gloss tshaj 6063, yuav tsum tau nruj tswj kev casting, homogenization thiab aging txheej txheem.
Kev ua haujlwm ntawm txhua lub ntsiab lus: Silicon thiab magnesium tsim ib qho kev sib xyaw ua ke ntawm cov khoom siv classic. Lawv qhov sib piv ncaj qha cuam tshuam rau nag lossis daus ntawm Mg₂Si cov theem ntxiv. Qhov sib piv ntawm Si-Mg tsis txaus ua rau lub zog tsis txaus, tsis ua tiav kev laus thiab kev ua haujlwm ntawm cov xuab zeb. Hlau yog ib qho tseem ceeb impurity; Cov hlau ntau dhau ua rau cov txheej txheem hlau nplua nuj, ua rau cov pob zeb dub, pitting thiab extrusion tawg, thiab txo qis cov txiaj ntsig ntawm anodizing. Tooj liab boosts lub zog tab sis impairs corrosion kuj ntawm cov ntsiab lus siab. Chromium thiab manganese refine nplej, txwv tsis pub recrystallization thiab txo qhov kev pheej hmoo ntawm kev ntxhov siab corrosion cracking. Titanium ua raws li cov nplej refiner los ua kom zoo dua cov pob zeb microstructure thiab tshem tawm cov pob zeb ntxhib. Zinc yog kho raws li impurity; zinc ntau dhau txo qhov kev tiv thaiv corrosion thiab feem ntau kuaj hauv kev txiav txim rau Tebchaws Europe thiab Asmeskas.
Nyob rau hauv xyoo tas los no, cov neeg yuav khoom tau tsim cov kev cai nruj ntxiv hais txog kev taug qab ntawm cov tshuaj muaj pes tsawg leeg thiab cov ntawv pov thawj ntawm cov ntaub ntawv. Cov neeg siv khoom feem ntau xav tau cov ntaub ntawv xeem raws li Optical Emission Spectroscopy (OES) tsom xam thaum tau txais cov khoom. Tsis tas li ntawd, lawv nruj me ntsis txwv tsis pub sib xyaw ntawm cov qib alloy lossis muaj cov ntsiab lus ntau tshaj qhov txwv-cov teeb meem feem ntau tshwm sim los ntawm kev tswj tsis txaus ntawm kev rov ua dua ntawm cov khoom seem. Txhawm rau hais txog qhov no, ntau cov chaw tsim khoom tau teeb tsa hauv-kab OES cov kab ke, tso cai rau lawv coj mus kuaj txhua pawg ntawm txhuas ntawv nyiaj tam sim tom qab casting. Los ntawm kev txheeb xyuas cov tshuaj lom neeg muaj pes tsawg leeg ntawm qhov chaw, cov tuam txhab tuaj yeem tiv thaiv cov lus thov loj hauv cov txheej txheem tom ntej, xws li extrusion, kev kho deg, thiab kev xa khoom zaum kawg.
Nyob rau hauv cov nqe lus ntawm kev lag luam tiam sis, cov pa 6063 thiab 6061 tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog tshiab, lub zog cia thiab kev tsheb ciav hlau. Kev tshawb fawb ntawm micro-alloyed formulations tau dhau los ua lub ntsiab lus kub. Los ntawm doping kab zirconium, vanadium los yog lub ntiaj teb tsis tshua muaj cov ntsiab lus, cov tuam txhab tuaj yeem txhim kho thermal conductivity, mechanical zog thiab corrosion kuj yam tsis muaj kev cuam tshuam extrusion kev ua tau zoo, catering rau high-end kev cai extrusion xws li sunflower tshav kub dab dej, lub zog cia vaj tse thiab lub teeb yuag structural Cheebtsam.
Cov kws tshaj lij hauv kev lag luam ceeb toom cov neeg yuav khoom tias kev xaiv qib tsis sib npaug ntawm kev ua haujlwm ruaj khov. Txawm nyob rau hauv tib qib, cov khoom kawg yog txiav txim siab los ntawm Si-Mg piv, kev tswj tsis huv, billet homogenization thiab txheej txheem kev laus. Ntau qhov kev lag luam txawv teb chaws cuam tshuam los ntawm kev siv cov khoom siv tsis zoo thiab kev sib cais sib cais, ua rau lub zog tsis sib haum thiab ua tiav hauv tib pawg. Tsiv mus tom ntej, kev sib tw hauv kev lag luam aluminium profile yuav hloov pauv ntawm tus nqi sib tw rau kev sib tw ua kom zoo hauv cov khoom tsim, muaj pes tsawg leeg stability thiab tag nrho cov txheej txheem zoo tswj. Kev tswj cov tshuaj muaj pes tsawg leeg yog qhov tseem ceeb ntawm kev sib tw ntawm high-end aluminium extrusion manufacturers thiab cov lag luam txawv teb chaws.
