Nyob rau hauv lub tshav pob ntawm shrbuilding, cov khoom xaiv yog ncaj qha cuam tshuam nrog kev nyab xeeb, durability thiab kev lag luam ntawm lub hull. Marine qib txhuas 5083 tau dhau los ua ib qho ntawm cov khoom tseem ceeb rau nws cov yam ntxwv zoo heev, muaj zog thiab cov yam ntxwv me me. Thiab nws cov ntsiab sib txawv txiav txim siab nws txoj kev siv hauv ntau qhov chaw ntawm lub nkoj.
Cov Khoom Yooj Yim Ntawm 5083 Aluminium Ntawv
5 {0 83 aluminium yog al-mg rust-allloy aliro, {}}. 7% manganese thiab 0.25% chromium. Cov ntsiab lus sib xws muab rau kuvt cov cwj pwm nram qab no:
Corrosion Kuj: kev ua tau zoo hauv marine chaw, tshwj xeeb tshaj yog se dej ntawm corrosion;
Lub zog siab: tawm lub zog tuaj yeem ncav cuag 275mpa, lub zog tensile yog li 310MPA;
Weldability: Yooj yim rau Weld, haum rau kev ua cov qauv hauv Hull qauv;
Lub teeb yuag: qhov ceev yog li 1/3 ntawm cov hlau, txo qis txo qhov hnyav ntawm lub nkoj thiab txhim kho roj efficiency.
Cov tempers uas muaj 5083 txhuas phaj txhuas
1. 5083-O
Txheej txheem: Ua tiav anealing, khoom muag muag;
Nta: tsis tshua muaj lub zog, tsis tshua muaj siab ntseeg siab;
Cov ntawv thov: ntu uas yuav tsum tau ua si los yog sib nqus (xws li kev ncaj ncees, cov taub hau tshwj xeeb);
Txwv: Kev kho kom sov ntxiv yog yuav tsum muaj ntxiv dag zog, thiab tus nqi yog qhov siab.
2. 5083-H111
Txheej Txheem: H111 Tlim yog cov kev hloov daim ntawv ntawm O thiab H321 Tem.
Nta: Lub zog: {{{{180-200 mpa mpa, tensile muaj zog:} mpa mpa mpa}
Daim Ntawv Thov: Feem ntau nws siv rau hauv nkoj decks, bulkheads thiab lwm yam uas xav tau rau lub zog qauv qauv. Lawv tuaj yeem tiv taus txhua hnub thauj thiab hloov kho kom me ntsis deformation ntawm lub hull hauv vuag.
Qhov Zoo: 40% Siab Loj Tshaj O State thiab 15% sib dua dua H321 Xeev
3. 5083-H321
Txheej Txheem: Tom qab ua haujlwm txias thiab ua haujlwm tawv, nws yog txav chaw thiab muaj ob qho muaj zog thiab tawv;
Nta: Nruab Nrab Lub zog, zoo corrosion tsis kam thiab nkees tsis kam;
Daim Ntawv Thov: Hull Plhaub, lawj, cov qauv sab thiab lwm qhov uas ua rau cov khoom siv thauj khoom;
Cov txiaj ntsig zoo: sib npaug lub zog thiab weldability, haum rau cov qauv welded.
4. 5083-H116
Txheej txheem: Tom qab ua haujlwm txias, qee qhov chaw muaj kev ntxhov siab tau khaws cia thiab cov npoo yog kho tshwj xeeb;
Nta: Zoo heev seaset dej kuj, tshwj xeeb tshaj yog intergranular corrosion tsis kam ntawm welds;
Cov ntawv thov: Underwater feem ntawm cov nkoj (xws li HULLS (xws li Hulls, Keels), roj tank bulleheads, thiab lwm yam;
Cov txiaj ntsig zoo: txo cov nqi kho thiab ncua kev pabcuam lub neej ntawm cov nkoj.
5. 5083-T6
Txheej txheem: Kev laus kev laus tom qab daws kev kho mob los txhim kho lub hardness;
Nta: theem siab tshaj plaws, tab sis me ntsis qis qis dua;
Daim Ntawv Thov: Nkoj Machinery nkhaus, Cov cuab yeej hnyav, thiab lwm yam .;
NCO TSEG: Zam kev ua haujlwm tsis zoo tom qab vuam.
5083 H321 thiab H116 yog cov kev xaiv tseem ceeb rau kev xaiv nkoj, noj mus rau hauv tus account lub zog, corrosion tsis kam thiab txheej txheem; Thaum O thiab T6 yog rau cov kev xav tau tshwj xeeb.
