RINA Kalasi AH32 DH32 EH32 FH32 Marine Steel Plate

Chombo chachitsulo cha m'madzi chimatanthawuza zitsulo zomwe zimagwiritsidwa ntchito pomanga zombo. Imaonedwa kuti ndi ya m'madzi ndipo iyenera kukana zowononga zomwe zimachitika m'madzi. Kuti izi zitheke, ma alloying apadera amawonjezedwa pamakalasi awa kuti atetezere ku corrosion.Ngakhale kuti zitsulo zambiri za carbon sizoyenera kumadera a m'madzi, pali zitsulo zingapo za carbon grade carbon zomwe zavomerezedwa ndi magulu osiyanasiyana kuti agwiritse ntchito ntchito zopanga zombo.

Structural zitsulo kwa hulls sitima lagawidwa m'magulu mphamvu malinga ndi mphamvu osachepera zokolola: ambiri mphamvu structural zitsulo ndi mkulu mphamvu structural zitsulo. Maine zitsulo mbale amatanthauza otentha adagulung'undisa zitsulo mbale opangidwa mogwirizana ndi zofunikira za gulu classication pomanga nyumba chombo chombo.

RINA AH32 chitsulo ndi mtundu wa otentha adagulung'undisa mkulu wamakono mphamvu chitsulo. Chitsulo chopangira zombo za RINA champhamvu kwambiri chimabwera m'makalasi 12 a mphamvu za 3, AH32 ndi imodzi mwamakalasi. Ma mbale achitsulo a RINA AH32 ali ndi mphamvu zopatsa mphamvu za 315 MPa), komanso mphamvu yomaliza ya 440-570 MPa. Zonse za RINA AH32 zopangira zombo zoperekedwa ndi Gnee zitha kutsimikiziridwa ndi RINA.

RINA ndi membala woyambitsa bungwe la International Association of Classification Societies (IACS), lomwe linakhazikitsidwa mu 1968. Zombo za RINA zimadziwika ndi akuluakulu pafupifupi 116 a mbendera za mayiko. Ntchito zophatikizika za RINA zophatikizira zonyamula katundu kuphatikiza mapangidwe, zomangamanga, kasamalidwe ka zombo, kuyang'anira ndi kuyesa zinthu / zigawo ndi kuyang'anira pafupipafupi kuti kalasiyi isungidwe zimagwiritsidwa ntchito ndi zonyamula katundu, zombo, ro-ro, zombo zonyamula anthu, ma yacht, zombo zapamadzi. , zombo zapamadzi, LGN ndi zombo zina zonyamula akatswiri.
Gulu la AH32 chitsulo ndi mphamvu yotsatiridwa ndi 0 ° C
Gulu la DH32 chitsulo chokhudza mphamvu pa  -20 ° C
Kalasi EH32 zitsulo mphamvu mphamvu pa -40 ° C
Gulu FH32 chitsulo mphamvu mphamvu pa -60 ° C

Ntchito yowombera mfuti
Kuwombera ndi njira yomwe imagwiritsidwa ntchito kuyeretsa kapena kupukuta zitsulo pakafunika kutero. Kuwombera kuwombera kumagwiritsidwa ntchito pafupifupi makampani onse omwe timatumikira. Makamaka pakupanga zombo, njanji, kupanga mapangidwe ndi zina zambiri.

Kalasi D, E (DH32, DH36, EH 32, EH 36)
Gulu D ndi E mndandanda (inlcuding AH32/36, DH32, DH36, EH32, EH36) zombo zitsulo mbale amafuna zabwino otsika kutentha kulimba ndi ntchito kuwotcherera wabwino. Kupanga zitsulo zopanga zitsulo zopanga zombo zamphamvu kwambiri kumayenera kukhazikika mwa kuwongolera ndikuwongolera kuziziritsa kapena njira zochizira kutentha ndi zida zonse. Panthawi imodzimodziyo, chiyero chamkati chachitsulo cha ma billets operekedwa chiyenera kukhala chapamwamba, makamaka zomwe zili mu S, P, N, 0 ndi H muzitsulo ziyenera kuyang'aniridwa mosamalitsa.

Zinthu za Alloy Zowonjezeredwa Kuti Zikhale Zolimba
Pofuna kuonetsetsa kuti mbale za sitimayo zamphamvu kwambiri zimagwira ntchito, teknoloji ya micro-alloying imatengedwa. Powonjezera Nb, V, Ti ndi zinthu zina zopangira zitsulo kuzitsulo, kuphatikizapo ndondomeko yoyendetsera kayendetsedwe kake, njere imayeretsedwa ndipo kulimba kumakula bwino.
Direction of Development for Shipbuilding Plate
Mphamvu zapamwamba, mawonekedwe apamwamba, ndi kukula kwakukulu ndi chitetezo cha sitimayo, ndi kusintha kwazitsulo zophimba, kufunikira kwa mapanelo wamba A-kalasi kumachepetsedwa pang'onopang'ono, ndipo kufunikira kwa mapanelo amphamvu kwambiri kukuwonjezeka, komwe kumakhazikika mu zombo zazikulu. m'lifupi 5m. Mbale, 200-300mm makulidwe apadera wandiweyani bolodi ngalawa.
