Kub Rolled Marine Steel Phaj Thiab Shipbuilding Steel Phaj

 

Khoom yam ntxwv

 

Tshuaj muaj pes tsawg leeg

Cov phaj no feem ntau muaj cov hlau, nrog rau kev tswj xyuas kom zoo ntawm cov pa roj carbon, manganese, silicon, thiab lwm yam. Piv txwv li, cov ntsiab lus carbon feem ntau yog nyob ntawm {{0}}.15% - 0.25% kom ntseeg tau tias muaj kev sib npaug zoo ntawm lub zog thiab ductility. Manganese, uas tej zaum yuav muaj nyob rau hauv ib ncig ntawm 0.6% - 1.6%, pab txhim kho cov neeg kho tshuab zog xws li toughness thiab hardenability.

Mechanical Properties

Lawv nthuav tawm cov khoom siv kho tshuab tshwj xeeb. Lub zog tawm los yog qhov tseem ceeb, feem ntau nyob rau hauv thaj tsam ntawm 235 - 355 MPa rau cov qib sib xws, uas qhia txog qhov kev ntxhov siab uas cov khoom pib deform plastically. Lub zog tensile tuaj yeem nyob ntawm 400 - 510 MPa, sawv cev rau qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus ua ntej tsis ua haujlwm. Tsis tas li ntawd, lawv muaj qhov zoo elongation qhov tseem ceeb, feem ntau nyob ib ncig ntawm 20% - 25%, uas qhia txog cov khoom muaj peev xwm ncav cuag yam tsis muaj kev tawg.

 

 

Kub Rolling

Tom qab steelmaking, cov hlau yog cam khwb cia rau hauv slabs los yog billets. Cov no yog tom qab ntawd rov ua kom sov hauv qhov cub cua sov kom sov, feem ntau nyob ib ncig ntawm 1000 - 1250 degree, kom cov hlau ua kom zoo dua. Cov rhuab slabs los yog billets yog dhau los ntawm ib tug series ntawm rollers nyob rau hauv lub kub dov zeb. Rollers txo qhov tuab thiab ua cov hlau rau hauv daim hlau ntawm qhov xav tau qhov ntev. Cov txheej txheem kub dov kuj tseem pab txhim kho microstructure ntawm cov hlau, txhim kho nws cov khoom siv kho tshuab.

Cov ntawv thov hauv Shipbuilding

 

Hull Kev Tsim Kho

Lawv tseem ceeb heev rau kev tsim kho lub nkoj lub nkoj. Cov phaj hauv qab ntawm lub hull yuav tsum tau tiv thaiv lub siab hydrostatic ntawm cov dej, qhov cuam tshuam ntawm nthwv dej, thiab qhov hnyav ntawm cov khoom thauj. Cov phaj sab thiab daim hlau lawj kuj ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ncaj ncees ntawm lub nkoj. Piv txwv li, nyob rau hauv ib lub thawv loj loj, daim hlau hull yuav muaj thicknesses li ntawm 10 - 30 hli nyob ntawm qhov chaw thiab cov qauv tsim.

Sab hauv cov qauv

Lawv yog siv rau fabricating ntau yam nyob rau hauv lub nkoj, xws li bulkheads, thav duab, thiab beams. Bulkheads faib lub nkoj sab hauv rau hauv cov khoom thiab muab lub zog thiab ruaj khov. Ncej thiab kab teeb txhawb lub hull thiab lwm yam khoom. Nyob rau hauv ib lub nkoj tanker, piv txwv li, cov bulkheads sab hauv thiab thav ntawv yog tsim los ntawm cov hlau phaj no kom ntseeg tau tias muaj kev nyab xeeb thiab kev thauj mus los ntawm cov khoom ua kua.
