Shipbuilding Steel Phaj
Dab tsi yog Nkoj Hlau Phaj
Nkoj phaj hais txog cov kub dov steel phaj ua raws li qhov yuav tsum tau ua ntawm Pawg Neeg Saib Xyuas Kev Tsim Kho Cov Qauv rau kev tsim cov qauv hull, hull structural steel raws li nws qhov tsawg kawg nkaus cov ntsiab lus muab faib ua ntau theem: lub zog dav dav hlau thiab lub zog loj steel qauv.
Qhov zoo ntawm nkoj phaj
Siab zog
Shipbuilding steel phaj muaj siab yield zog thiab tensile lub zog, uas muaj peev xwm tiv taus ib tug loj npaum li cas ntawm lwm loads thiab ua lub luag hauj lwm tseem ceeb nyob rau hauv shipbuilding thiab dej hiav txwv engineering.
Zoo Corrosion Resistance
Shipbuilding steel muaj zoo corrosion kuj thaum immersed nyob rau hauv seawater los yog lwm yam corrosive media, uas ua rau Shipbuilding steel phaj zoo heev rau engineering tej yaam num nyob rau hauv lub marine ib puag ncig.
Zoo heev Impact Toughness
Marine steel daim hlau muaj kev cuam tshuam zoo heev thiab muaj peev xwm tswj tau qhov cuam tshuam zoo ntawm qhov kub thiab txias, uas yog qhov tseem ceeb rau kev nyab xeeb ntawm cov nkoj hauv hiav txwv huab cua.
Ua raws li cov qauv thoob ntiaj teb
Cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm marine steel ua raws li cov qauv thoob ntiaj teb thiab tau lees paub los ntawm cuaj lub koom haum loj, uas ua rau Marine Steel Phaj yog lub ntiaj teb lees paub thiab siv dav siv cov khoom siv nkoj.
Classification ntawm Hull Structural Steel
General lub zog hull structural steel, uas yog, yav tas los marine carbon steel (mild steel), muab faib ua A, B, D, E plaub qib, muaj feem xyuam rau lub thickness ntawm tsis ntau tshaj 100 hli steel phaj. General lub zog hull structural steel plaub qib ntawm steel carbon, phosphorus thiab sulfur cov ntsiab lus ncaj qha cuam tshuam rau nws lub zog, siab dua cov ntsiab lus carbon, siab zog, dav dav lub zog hull structural steel hauv kev kho me me thiab nruab nrab - nkoj loj hauv daim ntawv thov ntau dua.
Lub zog loj hull structural steel tseem hu ua marine low alloy steel. Siab - lub zog hull cov qauv hlau raws li nws qhov tsawg kawg nkaus lub zog muaj zog cais cov qib zog, txhua qib zog thiab raws li qhov sib txawv ntawm qhov sib txawv toughness muab faib ua A, D, E, F thiab lwm yam 4 qib.
A32, D32, E32, F32 yield zog ntawm tsis pub tsawg tshaj 315N / mm ^ 2, tensile zog ntawm 440 ~ 570N / mm ^ 2, A, D, E, F, raws li, hais tias lawv 0 degree, -20 degree, -40 degree, -60℃yuav ua tau tiav nyob rau hauv qhov kev tshwm sim.
Lub zog tawm ntawm A36, D36, E36, F36 tsis tsawg dua 355N / mm ^ 2, lub zog tensile yog 490-620N / mm ^ 2, thiab A, D, E, F qhia qhov cuam tshuam toughness uas lawv txhua tus tuaj yeem ua tiav ntawm 0 degree, -20 degree, -40 degree, -60℃kev hwm.
A40, D40, E40, F40 muaj lub zog tawm ntawm tsis pub tsawg dua 390N / mm ^ 2 thiab lub zog tensile ntawm 510 txog 660N / mm^2, thiab A, D, E, thiab F qhia txog qhov cuam tshuam toughness uas txhua tus ntawm lawv tuaj yeem ua tiav ntawm 0 degree, -20 degree, -40 degree.
Hom Kev Siv Marine Steel
Hlau phaj yog qhov tseem ceeb ntawm cov qauv hull, suav txog li 60% mus rau 65%, xws li cov phaj hull, lawj phaj thiab compartment bulkheads, thiab lwm yam., dav dav ntawm steel phaj nyob rau hauv 4 hli thiab hauv qab no yog hu ua nyias phaj, ntau tshaj 4 hli yog hu ua tuab phaj; Qhov luaj li cas ntawm marine steel phaj feem ntau: 6 ~ 10mm tuab, 1200 ~ 3000mm dav, 6000 ~ 14000mm ntev.
Qhov feem ntawm steel seem nyob rau hauv lub hull qauv yog thib ob tsuas yog rau cov hlau phaj, txog 35% mus rau 40%, feem ntau yog siv raws li lub cev pob txha. Raws li nws tus ntoo khaub lig- seem duab tuaj yeem muab faib ua: steel hlau, pob tiaj tiaj steel, lub kaum sab xis steel, I-beam, T-beam thiab channel steel.
Nkoj lub taub hau thiab tus ncej puab, thauj tog rau nkoj, qhia cable qhov, bollard thiab tail ncej raj, thiab lwm yam. feem ntau siv cam khwb cia hlau, thaum lub nkoj lub rudder pas nrig, ncej thiab lwm yam yooj yim cov khoom ntawm lub Cheebtsam yog feem ntau siv forged steel. Forged steel mechanical zog thiab toughness yog zoo dua cam khwb cia hlau, tab sis vim hais tias ntawm cov kev txwv ntawm kev siv technology, cov qauv ntawm nws cov Cheebtsam yuav tsum tsis txhob yuav complex.
Kev Ntsuam Xyuas Zoo Ntawm Hull Steel Phaj
Kev tshuaj xyuas daim ntawv pov thawj zoo
