KR-A yog lub nkoj nkoj uas tau lees paub los ntawm Kaus Lim Kauslim Classification Society.
KR / A nkoj phaj yog tsim rau kev tsim cov nkoj hull cov qauv, cov chaw nres nkoj, cov chaw tsim khoom roj, cov kav dej hiav txwv, cov chaw tsim hluav taws xob hauv ntug dej hiav txwv, cov chaw nres nkoj thiab lwm qhov chaw nyob hauv dej hiav txwv, ntug hiav txwv dej thiab hauv av navigation.
KR Marine Steel Rau Shipbuilding Qib:
General zog nkoj plating: A, B, D, E.
High-strength nkoj daim hlau: AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH36
KR ABDE Marine Steel Rau Shipbuilding Loj:
Thickness: 3-80 hli,
Dav 1500-4000mm,
Ntev 4000-19000mm.
Muaj ntawv pov thawj los ntawm lub ntiaj teb cuaj pawg neeg loj (CCS, ABS, VL, LR, BV, NK, KR, RINA, RS).
KR ABDE Nkoj Hlau Phaj ntau lawm txheej txheem:
Steel ua - steel dov - kev kho cua sov - kev faib pawg neeg soj ntsuam thiab ntawv pov thawj
KR ABDE nkoj xa khoom raws li txoj cai:
Annealing, kub dov, normalizing, tswj dov, TM (sib txawv thickness, txawv tus me nyuam raws li txoj cai).
KR ABnkoj phaj yog lub zog muaj zog hlau rau lub nkoj hulls. Shipbuilding steel feem ntau yog hais txog steel rau cov qauv hull, uas yog hais txog cov hlau siv los tsim cov qauv hull uas ua raws li cov kev cai ntawm kev faib pawg neeg tsim khoom specifications. Nws yog feem ntau xaj, teem sijhawm thiab muag raws li cov hlau tshwj xeeb. Ib lub nkoj muaj cov nkoj nkoj, cov hlau zoo li tus, thiab lwm yam.
