Lr Abs Hlau Phaj Rau Shipbuilding

 

Cov ntawv thov hauv Shipbuilding:

 

Hull Kev Tsim Kho: LR / ABS steel phaj yog dav siv hauv kev tsim cov nkoj hulls. Lub zog siab thiab toughness ntawm cov phiaj no ua rau lawv tsim nyog rau kev tiv thaiv lub zog hydrostatic thiab dynamic loads los ntawm lub hull. Qhov sib txawv ntawm lub nkoj, xws li cov phaj hauv qab, daim hlau sab, thiab cov khoom loj, yuav xav tau cov thicknesses thiab qib ntawm cov hlau phaj nyob ntawm lub nkoj loj, hom, thiab kev siv.

Deck thiab Superstructure: Cov phaj hlau no tseem tuaj yeem siv rau kev tsim cov nkoj nkoj thiab cov khoom siv loj. Cov decks yuav tsum muaj zog txaus los txhawb nqa qhov hnyav ntawm cov khoom thauj, cov khoom siv, thiab cov neeg ua haujlwm, thaum lub superstructures yuav tsum muaj peev xwm tiv taus cua zog thiab kev vibrations. LR / ABS steel daim hlau tuaj yeem tsim rau hauv ntau cov duab thiab qhov ntau thiab tsawg kom tau raws li cov kev cai tshwj xeeb ntawm lub lawj sib txawv thiab cov khoom siv superstructure.

Tanks thiab Compartments: Kev tsim nkoj feem ntau suav nrog kev tsim cov tso tsheb hlau luam thiab cov chaw khaws cia roj, dej, thiab lwm yam kua dej. LR / ABS steel daim hlau nrog cov khoom tsim nyog corrosion kuj yog siv los xyuas kom meej kev ruaj ntseg ntawm cov tso tsheb hlau luam thiab cov khoom siv. Cov hlau daim hlau yuav raug welded los yog bolted ua ke los tsim cov dej tsis sib haum los yog roj nruj, nyob ntawm seb cov ntawv thov tshwj xeeb.

 

Hauv kev xaus, LR / ABS steel daim hlau rau nkoj tsim khoom yog cov ntaub ntawv tseem ceeb uas muaj kev sib xyaw ua ke ntawm lub zog siab, zoo toughness, weldability, thiab corrosion kuj. Lawv txoj kev xaiv thiab siv tau yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev siv lub neej ntev ntawm cov nkoj hauv thaj chaw marine.

Kev tsim cov LR ABS nkoj daim hlau feem ntau xav tau cov khoom siv hauv qab no:

 

Cov Khoom Siv Smelting:

 

Blast furnace: Siv rau smelting raw khoom xws li hlau ore thiab coke los ua npua hlau.

Converter: Ntxiv refines npua hlau, tshem tawm impurities, kho tshuaj muaj pes tsawg leeg, thiab smelts molten hlau uas ua tau raws li qhov yuav tsum tau specifications.

Refining rauv: xws li LF rauv (lag refining rauv), RH rauv (nqus ncig degassing refining rauv), thiab lwm yam, rau kev sib sib zog nqus refining ntawm molten steel kom meej tswj cov muaj pes tsawg leeg thiab purity ntawm molten steel kom tau raws li cov kev xav tau zoo ntawm nkoj daim hlau.

 

Cov cuab yeej Casting:

 

Nruam caster: Nruam nrum nrum refined molten steel rau hauv billets. Cov feem ntau yog cov slab nruam casters, uas tuaj yeem tsim cov pob zeb rau dov nkoj daim hlau.

 

Rolling Khoom:

 

Kub dov zeb: Kub dov nruam nruam billets. Los ntawm dov deformation ntawm qhov kub thiab txias, cov qauv sab hauv thiab cov khoom ntawm cov hlau tau txhim kho kom tau raws li qhov loj, cov duab, thiab cov cuab yeej cuab tam ntawm nkoj daim hlau, nrog rau cov roughing mills thiab xov mills.

Txias dov zeb (yog tias tsim nyog): Qee qhov xwm txheej, kev ua haujlwm txias dov yuav tsum tau ua kom zoo dua ntawm qhov zoo, qhov tseeb qhov tseeb, thiab cov khoom siv ntawm lub nkoj.

 

Cov khoom siv kho cua sov:

 

Cov cua kub cua sov: Siv rau cua sov nkoj daim hlau los ua cov txheej txheem kev kho cua sov xws li normalizing, annealing, thiab quenching los txhim kho cov qauv thiab cov khoom ntawm cov hlau, xws li nce lub zog thiab toughness.

Cov khoom siv quenching: xws li quenching dej tank thiab quenching roj tank, siv rau quenching steel.

 

Cov cuab yeej txiav:

 

Nplaim taws txiav tshuab: Siv cov nplaim hluav taws kub kub los txiav cov phaj hlau thiab tuaj yeem txiav cov dov nkoj daim hlau rau hauv qhov ntau thiab tsawg thiab cov duab.

Plasma txiav tshuab: tuaj yeem txiav cov phaj hlau ntau dua thiab tshwj xeeb tshaj yog haum rau cov neeg mob uas muaj kev txiav txim siab siab.

 

Cov Khoom Siv Kho Hniav:

 

Txhaj tshuaj tua blasting tshuab: Tshem tawm nplai, xeb, thiab lwm yam impurities nyob rau saum npoo ntawm lub nkoj daim hlau los ntawm kev ua cov ntaub ntawv abrasive xws li txhaj tshuaj steel los txhim kho qhov zoo ntawm qhov chaw thiab txheej adhesion.

Cov khoom siv pleev xim: Siv los siv cov xim tiv thaiv corrosion, xeb-pov thawj xim, thiab lwm yam txheej txheej ntawm lub nkoj daim hlau los txhim kho corrosion kuj ntawm nkoj daim hlau.

 

Cov cuab yeej kuaj xyuas zoo:

 

Ultrasonic flaw detector: Tshawb xyuas seb puas muaj cov teeb meem hauv nkoj nkoj, xws li tawg thiab suav nrog.
