LR Kalasi EH40 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.

LR EH40 zitsulo ndi mtundu wa otentha adagulung'undisa mkulu kumakokedwe mphamvu zitsulo. Chitsulo chomanga zombo za LR champhamvu kwambiri chimabwera m'makalasi 12 a mphamvu zitatu, DH40 ndi imodzi mwamagiredi. Zitsulo zachitsulo za LR DH40 zili ndi mphamvu zokolola za 56,500 psi (390 MPa), komanso mphamvu zomaliza za 74,000 - 94,500 psi (510-650 MPa).Zitsulo zonse za LR EH40 zomangira zombo zoperekedwa ndi Gnee zitha kutsimikiziridwa ndi Lloyd's Register of Shipping (LR). Gulu la EH40 chitsulo ndi mphamvu yomwe imakhudzidwa ndi -40 ° C

Gulu la DH40 chitsulo chokhudza mphamvu pa  -20 ° C
Kalasi EH40 zitsulo mphamvu mphamvu pa -40 ° C
Gulu FH40 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.

Kukonza Magiredi Osiyana
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.
