Kev txhim kho keeb kwm ntawm marine 5083 marine aluminium phaj
Aluminium alloys tuaj yeem muab faib ua ob pawg: ib qho yog deformed aluminium alloys, uas yog siv rau kev ua cov khoom ib nrab xws li daim hlau, strips, foils, raj, tuav, profiles, xov hlau, hmoov thiab forgings; lwm yam yog cam khwb cia txhuas alloys, uas yog siv rau casting ntau yam aluminium alloys. hom castings thiab tuag castings. Ntawm lawv, yav dhau los yog qhov siv dav tshaj plaws hauv kev tsim kho marine. Vim tias aluminium alloy muaj cov yam ntxwv ntawm lub zog tshwj xeeb, muaj zog tiv thaiv seawater corrosion, weldability, yooj yim ua thiab tsim, muaj zog recyclability, zoo ib puag ncig tiv thaiv, tsis muaj kub brittleness, tsis muaj hlau nplaum, tsis muaj sparking vim sib nqus sib tsoo, thiab lwm yam. daim ntawv thov ntawm marine qib 5083 txhuas phaj hauv dej hiav txwv Hauv qhov project, lub nkoj zoo tuaj yeem txo qis, kev ruaj khov thiab kev caij nkoj ceev tuaj yeem txhim kho. Yog li ntawd, tam sim no, aluminium alloy tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb ntawm cov nkoj hauv ntau lub teb chaws hauv ntiaj teb, thiab tau siv dav hauv kev tsim kho ntawm ntug dej hiav txwv, ntug dej hiav txwv thiab dej hiav txwv. Daim duab 1 qhia txog cov qauv txhuas ntawm lub tsev ntug dej hiav txwv. Vim lub siab corrosion kuj ntawm txhuas, nws yuav siv tau rau 30 xyoo yam tsis muaj tha xim thiab tu. Aluminium cov khoom tsis muaj qhov tsis zoo ntawm qhov cuam tshuam ua rau nws tsim tshwj xeeb rau kev tsim cov khoom siv hauv hiav txwv thiab cov qauv uas tuaj yeem cuam tshuam nrog cov khoom siv hluav taws xob thiab cov roj, txo qhov kev pheej hmoo ntawm hluav taws.
Marine qib 5083 txhuas phaj
Tam sim no, kev siv txhuas hauv kev lag luam shipbuilding tsis ntau, thiab lub ntiaj teb aluminium noj hauv 2013 suav txog li 1.1% ntawm tag nrho nws cov kev siv. Hauv 2012, Nyiv cov khoom siv txhuas hauv tsev yog 974.4kt, ntawm qhov kev siv tsheb thauj mus los yog 159.0kt (139.0kt hauv kev lag luam tsheb, suav txog 87.42% ntawm tag nrho, thiab cov khoom siv hauv tsev ntawm extruded aluminium yog 784.5 kt, ntawm cov kev thauj mus los yog 141.9kt (131.6kt hauv kev lag luam tsheb, suav txog 87.42%). 92.94%), kev siv ob hom txhuas hauv kev thauj mus los yog 17.11% ntawm tag nrho cov kev siv, thaum lub tsheb kev lag luam suav rau 89.93% ntawm cov khoom siv thauj mus los, thiab kev lag luam aviation thiab marine engineering account tsawg dua 10%. Nyiv yog lub teb chaws aerospace kev lag luam underdeveloped,
Cov qauv aluminium alloy ntawm Suav nkoj txawv ntawm Nyiv. Nyiv yog lub teb chaws loj hauv kev tsim cov LNG (liquefied natural gas) nkoj. Lub nkoj muaj plaub loj LNG cia tso tsheb hlau luam welded nrog marine 5083 txhuas daim hlau. Ultra-low kub brittle hlau-nickel-manganese steel yog siv los tsim LNG nkoj, thiab Tuam Tshoj tsuas yog tsim ib co marine-qib 5083 txhuas ntawv los tsim cov nkoj me thiab nruab nrab. Txawm li cas los xij, nrog rau kev ua kom nrawm thiab txhim kho cov txheej txheem ntawm kuv lub teb chaws lub zog hiav txwv, kev siv txhuas ntawm cov nkoj, cov nkoj thiab cov tubrog nkoj engineering yuav nce siab heev, tab sis qhov nruab nrab txhua xyoo kev loj hlob yuav tsis pub tshaj 7.
Kev tsim khoom ntawm txhuas tau pib hauv xyoo 1988 thaum lub ntiaj teb thawj cov nroj tsuag txhuas, Pittsburgh Metallurgical Company ntawm Tebchaws Meskas, tau muab tso rau hauv kev ua haujlwm. Xyoo 1891, kev lag luam shipbuilding siv cov txhuas uas tsim los ntawm cov nroj tsuag thawj zaug los tsim cov khoom nkoj. Tom qab ntau tshaj 120 xyoo ntawm kev tshawb fawb thiab kev loj hlob, txhuas tau ua ntau thiab dav siv nyob rau hauv ships thiab marine engineering, thiab tau dhau los ua ib qho ntawm cov khoom pheej yig tshaj plaws hauv cov teb no.
Qhov ntxov tshaj plaws aluminium alloys siv nyob rau hauv shipbuilding yog Ni-muaj Al-Cu alloys, ua raws li los ntawm 2000 series alloys, tab sis lawv corrosion kuj rau seawater tsis siab, uas txwv lawv daim ntawv thov nyob rau hauv lub nkoj tsim kev lag luam.
Hauv xyoo 1930, 6061-T6 alloy tau siv, thiab lub plhaub tau tsim los ntawm riveting. Corrosion-resistant 5xxx series alloys tuaj yeem welded nyob rau xyoo 1940, thiab TIG (tungsten inert gas) vuam tshuab tau txais hauv xyoo 1950. Nyob rau lub sijhawm no, kev siv cov aluminium alloys hauv nkoj tsim tau ua tiav zoo. H321 alloy phaj, 5086-H111 thiab 5456-H111 alloy extruded profiles tshem tawm Al8Mg5 composite network zaj duab xis precipitated raws cov siv lead ua, thiab daws cov teeb meem ntawm exfoliation corrosion thiab intergranular corrosion vim yog siv H116 thiab H117 xeev , uas yog qhov tseem ceeb tshaj plaws Kev nce qib hauv kev txhim kho naval aluminium alloys hauv xyoo 1960. Tom qab ntawd, vim qhov xav tau ntawm cov khoom siv nrog cov txiaj ntsig zoo dua, 6xxx series alloys tau siv dav hauv kev tsim kho nkoj nkoj. Rau lub sijhawm ntev, Tebchaws Europe, Asmeskas thiab Nyij Pooj feem ntau siv cov khoom siv aluminium alloys hauv 5000 series alloys thiab 6000 series alloys, thaum Soviet Union xaiv ntau dua 2xxx series alloys. Ua ntej kev hloov kho thiab qhib, Suav tub rog feem ntau ua raws li Soviet Union. Txij li thaum xyoo 1980, nws tau ua raws Europe, Amelikas thiab Nyij Pooj ntau dua. Tom qab xyoo 2010, kev ywj pheej innovation tau maj mam ntxiv dag zog. Txij li thaum xyoo 1970, kev tshawb fawb ntawm nruab nrab-lub zog weldable 7xxx series alloys tau nce ntxiv, thiab qee qhov kev vam meej tau ua tiav, uas tau siv rau kev tsim khoom nkoj.
Tom qab xyoo 1970s, qhov kev txiav txim siab thiab qhov hnyav ntawm cov qauv naval tau them ntau dua thiab ntau dua, thiab aluminium alloys tau siv dav hauv kev tsim kho thiab cov khoom siv ntawm cov nkoj loj. Txog rau qhov kawg no, ntau cov aluminium alloys thiab cov khoom siv rau cov teb no tau tsim nyob rau lub sijhawm no, suav nrog extruded profiles ntawm tshwj xeeb specifications, loj extruded panels thiab castings.
