Khoom Description
Cov qauv tsim rau LR Marine Steel Phaj Qib B feem ntau suav nrog cov hauv qab no:
Mechanical Property Requirements:
Yield zog: Tsis pub tsawg tshaj 235MPa. Lub zog tawm los yog tus nqi kev ntxhov siab uas cov hlau pib tsim cov yas deformation thiab yog qhov tseem ceeb rau kev ntsuas lub zog ntawm cov hlau.
Tensile zog: Nruab nrab ntawm 400 - 520MPa. Lub zog tensile yog tus nqi siab tshaj plaws uas cov hlau tuaj yeem tiv taus thaum lub sijhawm tensile txheej txheem thiab qhia txog qhov kawg ntawm cov kabmob ntawm cov hlau.
Elongation: Nyob ntawm qhov sib txawv thicknesses thiab specifications, elongation yuav tsum sib txawv, tab sis feem ntau nws yuav tsum tau nyob rau hauv ib tug tej yam ntau yam. Piv txwv li, tsis pub tsawg tshaj 21% nyob rau hauv ib tug 200mm gauge ntev thiab tsis tsawg tshaj li 24% nyob rau hauv ib tug 50mm gauge ntev.
Impact toughness: Ua cov kev ntsuam xyuas cuam tshuam ntawm qhov kub ntawm -20 degree , thiab lub zog cuam tshuam yuav tsum ua kom tau raws li cov qauv tsim nyog. Kev cuam tshuam zoo tuaj yeem ua kom ntseeg tau tias cov hlau tseem muaj kev cuam tshuam zoo nyob rau hauv qhov chaw qis qis thiab tsim nyog rau cov nkoj caij nkoj hauv dej hiav txwv txias.
Cov txheej txheem tsim khoom xav tau:
Smelting: Txais cov txheej txheem smelting tsim nyog los xyuas kom meej lub purity ntawm molten steel thiab nruj me ntsis tswj cov ntsiab lus ntawm impurity ntsiab nyob rau hauv steel.
Rolling: Rolling txheej txheem xws li kub dov, tswj dov, thiab normalizing yuav siv tau kom tau zoo microstructure thiab mechanical zog. Rau cov hlau phaj nrog lub thickness ntau dua 40mm, normalizing kev kho cua sov yog pom zoo.
Kev tswj kom zoo: Thaum lub sij hawm tsim cov txheej txheem, yuav tsum muaj kev tswj xyuas zoo thiab tshuaj xyuas, suav nrog tshuaj lom neeg kev tshuaj ntsuam xyuas, kev ntsuas cov cuab yeej cuab tam, ntsuas qhov ntev, thiab kev tshuaj xyuas qhov zoo ntawm qhov chaw kom ntseeg tau tias qhov zoo ntawm cov phaj hlau ua tau raws li tus qauv yuav tsum tau ua.
