Txoj Kev Txhim Kho Keeb Kwm Ntawm Marine Qib 5083 Aluminium Sheet Rau Nkoj

Aluminium alloys tuaj yeem muab faib ua ob pawg: ib qho yog deformed aluminium alloys, uas yog siv los ua cov khoom ua tiav xws li daim hlau, strips, foils, raj, rods, duab, xov hlau, hmoov thiab forgings; lwm yam yog cam khwb cia txhuas alloys, uas yog siv los cam khwb cia ntau yam ntawm castings thiab tuag-castings. Ntawm lawv, cov qub yog feem ntau siv nyob rau hauv marine engineering. Txij li thaum aluminium alloy muaj cov yam ntxwv ntawm lub zog tshwj xeeb, muaj zog tiv thaiv dej hiav txwv corrosion, weldable, yooj yim ua thiab tsim, muaj zog rov ua dua tshiab, kev tiv thaiv ib puag ncig zoo, tsis muaj qhov kub thiab txias, tsis muaj hlau nplaum, tsis muaj lub txim thaum sib nqus sib tsoo, thiab lwm yam. ntawmmarine qib 5083 txhuas ntawvnyob rau hauv marine engineering tuaj yeem txo qhov zoo ntawm cov nkoj, txhim kho kev ruaj ntseg thiab nce kev ceev ntawm navigation. Yog li ntawd, tam sim no aluminium alloy tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb rau cov nkoj hauv ntau lub teb chaws hauv ntiaj teb, thiab tau siv dav los tsim cov chaw ntug dej hiav txwv, pas dej 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 tsis tas yuav tsum tau pleev xim rau thiab tsis tas yuav tu, thiab siv tau rau 30 xyoo. Cov yam ntxwv uas aluminium tsis tsim sparks thaum sib tsoo ua rau nws tshwj xeeb tshaj yog haum rau kev tsim khoom ntawm lub nkoj thiab cov qauv hauv kev sib cuag nrog cov khoom siv hluav taws xob thiab roj, uas tuaj yeem txo qhov kev pheej hmoo ntawm hluav taws.

Tam sim no, txhuas tsis tau siv ntau hauv kev tsim nkoj, thiab rau lub ntiaj teb, tus nqi siv hauv 2013 yog kwv yees li 1.1 feem pua ​​​​ntawm nws cov khoom siv tag nrho. 2012 kev noj khoom noj hauv tsev ntawm cov dov aluminium hauv Nyij Pooj yog 974.4kt, ntawm 159.0kt tau siv hauv kev thauj mus los (139.0kt hauv kev lag luam tsheb, suav txog 87.42 feem pua, thiab kev siv khoom siv hauv tsev ntawm extruded aluminium yog 784.5kt, ntawm uas cov tsheb thauj mus los 141.9kt (131.6kt rau kev lag luam tsheb, suav txog 92.94 feem pua), tus nqi ntawm ob hom txhuas hauv kev thauj mus los suav txog 17.11 feem pua ​​​​ntawm tag nrho cov kev siv, thaum tus nqi ntawm kev lag luam tsheb suav txog 89.93 feem pua. cov ntaub ntawv siv hauv kev thauj mus los, tus nqi ntawm kev lag luam aviation thiab marine engineering tsawg dua 10 feem pua, Nyiv yog lub tebchaws uas muaj kev lag luam aerospace underdeveloped, yog li nyob rau hauv kev thauj mus los nrog Nyiv yog lub teb chaws uas muaj underdeveloped aerospace kev lag luam, yog li nws yog kwv yees tias. tus nqi ntawm txhuas siv nyob rau hauv kev thauj mus los thiab marine engineering yuav tsis pub tshaj 5 feem pua, thiab kev noj ntawm txhuas nyob rau hauv Nyiv muaj ntev ente. liab ib theem ruaj khov, thiab cov nqi ntawm marine engineering thiab ships tau hovering nyob ib ncig ntawm 20kt/a txij li thaum 2004. Nyob rau hauv lub txhuas siv, marine qib 5083 txhuas ntawv yog cov khoom tseem ceeb, accounting txog 88 feem pua, thiab cov khoom extruded yog supplementary, tab sis cov chaw ntug dej hiav txwv feem ntau yog siv rau cov khoom siv extruded.

Suav ships nrog txhuas alloy qauv yog txawv ntawm Nyiv, Nyiv yog ib tug loj LNG (liquefied natural gas) nkoj tsim lub teb chaws, lub nkoj muaj plaub loj nrog marine qib 5083 txhuas ntawv welded LNG tank, tus nqi marine qib 5083 txhuas ntawv txog 4kt. / ib lub nkoj, Tuam Tshoj ua LNG ships nrog meta-low kub brittle Fe-Ni-Mn steel, Tuam Tshoj tsuas yog ib co marine qib 5083 txhuas ntawv manufacturing me me thiab nruab nrab ships, nws yog kwv yees hais tias nyob rau hauv 2014 Tuam Tshoj lub shipbuilding kev lag luam nrog txhuas yog tsawg dua 230kt, uas yog tsawg dua 1 feem pua ​​​​ntawm tag nrho cov kev pom tseeb ntawm txhuas. Txawm li cas los xij, nrog kev nrawm thiab nce ntawm Tuam Tshoj txoj kev nce qib mus rau lub zog dej hiav txwv, tus nqi ntawm txhuas hauv nkoj, nkoj nkoj thiab nkoj nkoj nkoj yuav muaj kev loj hlob ntau dua, tab sis qhov nruab nrab txhua xyoo kev loj hlob yuav tsis pub tshaj 7.5 feem pua ​​​​ua ntej 2025.

Kev lag luam tsim khoom ntawm txhuas tau pib los ntawm lub ntiaj teb thawj aluminium cog - Tebchaws Asmeskas Pittsburgh Metallurgical Company tau ua tiav thiab muab tso rau hauv kev ua haujlwm hauv xyoo 1988. Xyoo 1891, kev lag luam shipbuilding siv aluminium shipbuilding qhov chaw tsim los ntawm cov nroj tsuag thawj zaug. Tom qab ntau tshaj 120 xyoo ntawm kev tshawb fawb thiab kev loj hlob, daim ntawv thov ntawm txhuas nyob rau hauv ships thiab nkoj thiab nyob rau hauv marine engineering tau dhau los ua ntau thiab dav, thiab tau dhau los ua ib qho ntawm cov khoom muaj txiaj ntsig hauv cov haujlwm no.

Qhov ntxov tshaj aluminium alloy siv nyob rau hauv shipbuilding yog Al-Cu system alloy muaj Ni, ua raws li los ntawm 2000 series alloy, tab sis lawv corrosion kuj rau seawater tsis siab, uas txwv lawv daim ntawv thov nyob rau hauv shipbuilding kev lag luam.

Hauv xyoo 1930, 6061-T6 alloy tau txais yuav thiab lub plhaub tau tsim los ntawm txoj kev riveting. 5xxx series alloy nrog corrosion kuj yuav welded nyob rau hauv 1940s, thiab TIG (Tungsten Inert Gas) vuam tshuab tau txais nyob rau hauv lub xyoo 1950s, thiab daim ntawv thov ntawm txhuas alloy nyob rau hauv shipbuilding ua tau zoo nyob rau hauv lub sij hawm no. H321 alloy daim hlau, 5086-H111 thiab 5456-H111 alloy extrusion profiles, uas tshem tawm Al8Mg5 compound mesh zaj duab xis precipitated raws cov siv lead ua thiab daws lawv spilling corrosion thiab intergranular corrosion teeb meem vim yog saws ntawm H116 thiab H117 xeev , uas yog qhov tseem ceeb hauv kev txhim kho ntawm naval aluminium alloys hauv xyoo 1960. Tom qab ntawd, vim qhov xav tau ntawm cov khoom siv nrog lub zog muaj zog ntau dua, 6xxx series alloys tau siv dav hauv kev tsim nkoj nkoj. Rau lub sijhawm ntev, European, Asmeskas thiab Nyij Pooj lub teb chaws feem ntau xaiv hull aluminium alloys ntawm 5000 series alloys thiab 6000 series alloys, thaum lub Soviet Union xaiv 2xxx series alloys ntau zaus. Suav naval kev lag luam feem ntau ua raws li Soviet Union ua ntej kev hloov kho thiab qhib, thiab ntau ua raws li European, Asmeskas thiab Nyij Pooj txij li xyoo 1980, thiab kev ywj pheej innovation tau maj mam ntxiv zog tom qab 2010. Txij li xyoo 1970, kev tshawb fawb ntawm nruab nrab-lub zog weldable 7xxx series alloys muaj. tau nce, thiab qee qhov kev nce qib tau ua tiav, uas tau siv rau hauv kev tsim nkoj.

Tom qab xyoo 1970s, qhov kev txiav txim siab thiab lub teeb yuag ntawm naval qauv tau them nyiaj ntau thiab ntau dua, thiab cov khoom siv loj thiab cov khoom siv ntawm cov nkoj loj siv txhuas alloys hauv ntau qhov ntau. Vim li no, ntau aluminium alloys thiab cov ntaub ntawv rau cov teb no tau tsim nyob rau hauv lub sij hawm no, nrog rau tshwj xeeb specification extruded profiles, loj dav extruded phab ntsa daim hlau thiab castings, thiab lwm yam.
