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.
