Lub zog dav dav CCS (China Classification Society) marine steel daim hlau ntawm qib A, B, D, thiab E tau siv dav hauv cov chaw tsim khoom hauv nkoj rau kev tsim cov nkoj. Nov yog cov lus qhia ntxaws ntxaws txog lawv:

1. Cov qauv thiab Specifications

 

Cov hlau phaj no ua raws li cov qauv thiab cov kev cai uas tsim los ntawm Tuam Tshoj Classification Society. CCS muaj cov cai nruj heev txog lawv cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, cov txheej txheem tsim khoom, thiab kev tshuaj xyuas zoo kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov nkoj tsim siv cov ntaub ntawv no.

2. Tshuaj muaj pes tsawg leeg

 

Qib A:

Cov ntsiab lus carbon (C) feem ntau yog nyob ib ncig ntawm 0.21% siab tshaj.

Silicon (Si) cov ntsiab lus feem ntau nyob hauv 0.35% siab tshaj.

Manganese (Mn) cov ntsiab lus feem ntau yog nyob hauv thaj tsam ntawm 0.60% - 1.20%.

Phosphorus (P) cov ntsiab lus yog txwv rau 0.035% siab tshaj.

Sulfur (S) cov ntsiab lus yog txwv rau 0.035% siab tshaj plaws.

Qib B:

Zoo ib yam li Qib A hauv ntau yam, tab sis nrog kev hloov kho tshwj xeeb hauv qee lub ntsiab lus kom ua tau raws li nws qhov yuav tsum tau ua. Piv txwv li, cov ntsiab lus ntawm cov pa roj carbon monoxide kuj tseem tswj tau nyob rau hauv ib qho kev ua kom muaj zog thiab weldability.

Qib D:

Nws muaj kev tswj nruj dua ntawm impurities. Cov ntsiab lus ntawm sulfur thiab phosphorus feem ntau qis dua qib A thiab B. Piv txwv li, cov ntsiab lus sulfur yuav raug txwv rau ib ncig ntawm 0.025% siab tshaj plaws los txhim kho nws cov tawv nqaij, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias.

Qib E:

Qib no muaj cov kev cai nruj tshaj plaws ntawm cov tshuaj muaj pes tsawg leeg ntawm lawv. Cov ntsiab lus sulfur feem ntau yog txo qis dua, feem ntau yog nyob ib ncig ntawm 0.020% siab tshaj, thiab cov ntsiab lus phosphorus kuj tau ua tib zoo tswj. Tsis tas li ntawd, nws yuav muaj qee yam alloying cov ntsiab lus hauv qhov tsim nyog los txhim kho nws qhov kub tsis tshua muaj kev cuam tshuam toughness.

3. Mechanical Properties

 

Yield zog:

Qib A: Qhov tsawg kawg nkaus tawm lub zog yog nyob ib ncig ntawm 235 MPa.

Qib B: Kuj muaj qhov tsawg kawg nkaus tawm lub zog ntawm kwv yees li 235 MPa.

Qib D: Qhov tsawg kawg nkaus tawm lub zog yog feem ntau 235 MPa ib yam nkaus.

Qib E: Nws qhov tsawg kawg nkaus tawm lub zog yog li 235 MPa.

 

Elongation:

Lawv feem ntau muaj qhov yuav tsum tau elongation feem pua ​​los xyuas kom meej cov hlau ductility. Feem ntau, qhov elongation tom qab tawg yuav tsum tsis pub tsawg tshaj 22% (nyob ntawm seb qhov kev ntsuas tshwj xeeb thiab qhov loj me).

Impact Properties:

Qib A: Feem ntau tsis muaj cov cai tshwj xeeb rau kev ntsuas qhov ntsuas kub qis hauv qhov xwm txheej ib txwm muaj.

Qib B: Nws yuav tsum xeem dhau qhov kev ntsuam xyuas ntawm 0 degree . Qhov cuam tshuam lub zog absorbed yuav tsum ua kom tau raws li cov nqi teev tseg raws li cov qauv tsim nyog.

Qib D: Yuav tsum xeem dhau qhov kev ntsuam xyuas qhov cuam tshuam ntawm -20 degree nrog rau qhov xav tau qhov tsawg kawg nkaus lub zog.

Qib E: Yuav tsum dhau qhov kev ntsuam xyuas qhov cuam tshuam ntawm -40 degree , thiab qhov cuam tshuam lub zog yuav tsum ncav cuag tus qauv tsim nyog los xyuas kom meej qhov kub thiab txias toughness.

4. Cov khoom zoo

 

Muaj zog txaus: Nrog cov txiaj ntsig tsim nyog thiab lub zog tensile, lawv tuaj yeem nqa cov khoom thauj thiab kev ntxhov siab uas cov nkoj tau dhau los thaum lub sijhawm ua haujlwm ib txwm muaj thiab hauv ntau yam dej hiav txwv.

Low-Temperature Toughness: Qib D thiab E, tshwj xeeb tshaj yog, muaj qhov ua tau zoo ntawm qhov kub thiab txias, uas yog qhov tseem ceeb heev rau cov nkoj caij nkoj hauv hiav txwv txias kom tsis txhob muaj cov pob txha tawg.

 

5. Daim ntawv thov teb

 

Hull Kev Tsim Kho: Lawv feem ntau yog siv los tsim cov hulls ntawm ntau lub nkoj, nrog rau cov nkoj thauj khoom, nkoj nuv ntses, thiab cov nkoj me me mus rau nruab nrab cov neeg caij nkoj.

Sab hauv cov qauv: Kuj tseem siv tau rau hauv kev tsim cov khoom siv sab hauv hauv lub nkoj, xws li bulkheads, decks, thiab thav ntawv.

6. Feem ntau Specifications

 

Thickness: Feem ntau yog nyob ntawm ob peb millimeters mus txog 50 mm. Piv txwv li, cov thicknesses siv nyob rau hauv shipyards tej zaum yuav 6 hli, 8 hli, 10 hli, 12 hli, thiab lwm yam.

Dav: Feem ntau ntawm 1000 hli thiab 3000 hli.

Ntev: tuaj yeem kho raws li qhov xav tau tiag tiag ntawm kev tsim cov nkoj nkoj, feem ntau nyob rau hauv ntev ntawm ob peb meters mus rau kaum ntawm meters.

7. Kev kho deg

 

Qhov saum npoo ntawm cov hlau phaj no yuav nyob rau hauv lub xeev raws li dov los yog tau txais kev kho mob ntxiv xws li txhaj tshuaj blasting kom tshem tawm xeb thiab txhim kho qhov zoo ntawm cov xim kom zoo dua xim adhesion thiab corrosion kuj ua ntej siv hauv nkoj tsim.

8. Ntim thiab thauj

 

Ntim: Feem ntau ntim nrog cov khoom siv tiv thaiv corrosion xws li yas zaj duab xis los yog cov ntawv tsis muaj dej los tiv thaiv lawv ntawm cov dej noo thiab xeb thaum khaws cia thiab kev thauj mus los.

Kev thauj mus los: Lawv tuaj yeem thauj tau los ntawm av (cov tsheb thauj khoom) lossis hiav txwv (kev thauj khoom) nyob ntawm qhov deb thiab cov kev xav tau tshwj xeeb. Lub ntim yog tsim los xyuas kom meej cov hlau daim hlau nyob twj ywm nyob rau hauv zoo nyob rau hauv tag nrho cov txheej txheem kev thauj mus los.
