CCS / DH40 Hlau Phaj Rau Shipbuilding

CCS / DH40 steel phaj rau nkoj tsim khoom yog cov khoom siv zoo nrog cov khoom tshwj xeeb thiab cov yam ntxwv.

 

Khoom thiab yam ntxwv:

 

Siab zog: DH40 steel muaj lub zog zoo heev, ua rau nws tuaj yeem tiv taus qhov hnyav marine ib puag ncig thiab ntau yam loads. Lub zog no yog qhov tseem ceeb rau kev ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov nkoj.

Weldability zoo: Cov hlau phaj muaj qhov zoo weldability, tso cai rau kev tsim khoom thiab kev tsim kho. Vuam yog ib txoj hauv kev hauv kev tsim cov nkoj, thiab cov khoom siv zoo weldability ua kom cov pob qij txha muaj zog thiab txhim khu kev qha.

Corrosion Resistance: Cov nkoj tau raug dej ntsev tas li thiab lwm yam khoom corrosive. CCS / DH40 steel phaj yog tsim los kom muaj qee qhov kev tiv thaiv corrosion kom ntev nws lub neej kev pab cuam.

Impact Resistance: tuaj yeem tiv taus cov khoom thauj, muab kev nyab xeeb thiab kav ntev rau cov nkoj. Kev cuam tshuam tsis zoo yog qhov tseem ceeb rau cov nkoj uas tuaj yeem ntsib kev sib tsoo lossis lwm yam khoom hnyav.

Thermal stability: Nws muaj qhov zoo thermal stability, uas yog ib qho tseem ceeb rau cov nkoj ua haujlwm nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias. Nws tuaj yeem tswj hwm nws cov khoom siv kho tshuab thiab kev ua haujlwm ruaj khov txawm tias qhov kub thiab txias.

 

 

 

 

 

Specification peb muab:

Thickness	2-200 hli
Dav	1000-4000 hli
Ntev	5000-15000 hli

 

 

 

Raws li qhov sib txawv ntawm kev ua tau zoo thiab qhov ntsuas kub thiab lwm yam, shipbuilding steel phaj CCS / DH40 tuaj yeem muab faib ua cov qib hauv qab no:

 

Qib DH40: Qhov no yog qib DH40 yooj yim tshaj plaws, nrog cov khoom muaj zog thiab lub zog tensile, uas tuaj yeem ua tau raws li kev siv ntawm cov qauv nkoj dav dav. Nws lub zog tawm los feem ntau tsis tsawg dua 390 MPa (megapascals), thiab lub zog tensile yog nyob nruab nrab ntawm 510 MPa thiab 660 MPa.

Z-kev taw qhia kev ua tau zoo qib: Raws li DH40, qhov yuav tsum tau ua rau kev ua tau zoo nyob rau hauv cov kev taw qhia tuab ntawm steel phaj, uas yog, Z-kev taw qhia kev ua tau zoo, yog ntxiv. Piv txwv li, DH40-Z15, DH40-Z25, DH40-Z35, thiab lwm yam. Cov lej tom qab qhia txog kev tiv thaiv cov txheej txheem tearing qib ntawm steel phaj nyob rau hauv cov kev taw qhia tuab. Qhov loj dua tus naj npawb, qhov zoo dua cov txheej txheem tearing kev ua tau zoo. Qib no ntawm steel phaj yog haum rau qhov chaw ntawm cov qauv nkoj uas muaj kev xav tau ntau dua rau kev ua tau zoo hauv cov kev taw qhia tuab, xws li tuab phaj welded qauv ntawm cov nkoj loj.

Cov qib sib txawv ntawm qhov kub thiab txias:

DH40 (qhov kub ib txwm cuam tshuam): Cov kev ntsuas cuam tshuam tau ua rau qhov kub thiab txias thiab tsim nyog rau cov khoom siv nkoj nrog cov kev xav tau qis rau kev ua haujlwm kub qis lossis cov qauv nkoj siv nyob rau hauv ib puag ncig kub.

DH40 (-20 degree cuam tshuam): Qhov no yog qhov feem ntau cuam tshuam qhov ntsuas kub rau DH40 steel daim hlau. Nws tuaj yeem ua tau raws li qhov yuav tsum tau siv ntawm cov nkoj hauv qhov kub thiab txias ib puag ncig thiab xyuas kom meej tias cov phaj steel tseem muaj qhov zoo toughness thiab cuam tshuam tsis zoo nyob rau hauv cov dej hiav txwv txias los yog kub kub ua haujlwm.

DH40 (-40 degree cuam tshuam) thiab qis dua qhov ntsuas kub: Rau cov nkoj ua haujlwm hauv hiav txwv txias heev lossis qhov chaw kub kub tshwj xeeb, DH40 steel daim hlau uas muaj qhov ntsuas qhov ntsuas kub qis yuav xav tau, xws li kev cuam tshuam kev ua haujlwm ntawm -40 degree lossis txawm tias qis dua los ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov qauv nkoj.
Nyob rau hauv luv luv, cov qib sib txawv ntawm shipbuilding steel phaj CCS / DH40 yog ua kom tau raws li cov qauv kev cai thiab siv ib puag ncig ntawm ntau qhov chaw ntawm nkoj. Thaum xaiv, kev txiav txim siab dav dav yuav tsum tau muab raws li cov qauv tsim nkoj tshwj xeeb, siv ib puag ncig thiab kev xav tau kev ua haujlwm.
