Siab -Strength Qib B Shipbuilding Steel Phaj rau Vessel Siv
PebQib B Shipbuilding Steel Phajyog ib qho dav dav - lub zog ntawm cov qauv steel qib ntawv pov thawj hauv qabASTM A131/A131Mthiab cov koom haum faib loj suav nrogABS, BV, LR, DNV, thiab CCS. Tsim tshwj xeeb rau kev tsim lub nkoj hull, cov khoom siv hauv hiav txwv, thiab cov qauv hauv ntug dej hiav txwv, Qib B steel muaj kev sib xyaw ua ke ntawm weldability, toughness, thiab corrosion kuj rau nruab nrab marine ib puag ncig.
Raws li ib tugntseeg siab steel phaj tsumnrog ntau tshaj 10,000 tons txhua hli muaj peev xwm, peb muab customized ntau thiab tsawg los ntawm4mm txog 200mm hauv thicknessthiabmus txog 4000mm nyob rau hauv dav. Txhua daim hlau muaj nyob nrogKev xaiv kho cua sovsuav nrog normalized, quenched, thiab tempered tej yam kev mob kom tau raws li tej yam yuav tsum tau ua ib qhov project.
Vim li cas thiaj xaiv Qib B?
Ib - nres kev yuav khoom steel
Zoo Toughness dua qib A:Qhov yuav tsum tauCharpy V-qhov ntsuas qhov cuam tshuam ntawm 0 degreeUa kom Qib B steel ua tau zoo hauv cov dej hiav txwv txias, thaum Qib A tsis muaj kev tiv thaiv kev tiv thaiv.
Optimized Weldability:Cov ntsiab lus manganese siab dua (Ntau dua lossis sib npaug li 0.80%) txhim kho deoxidation thiab grain refinement, txo cov vuam tsis xws luag piv rau Qib A.
Tus nqi -Txoj kev xaiv zoo rau qib D:Rau cov nkoj ua haujlwm hauv cov huab cua nruab nrab (tsis yog huab cua sub- xoom), Qib B muab qhov muaj zog txaus ntawm tus nqi qis dua Qib D.
SivQib Arau superstructures thiab tsis yog - cov khoom tseem ceeb;Qib Brau cov kab mob loj hauv cov dej kub; thiabQib Drau cov dej khov-cov nkoj hauv chav kawm lossis cov chaw tawm sab nraud hauv thaj chaw arctic.

FAQ
01.Dab tsi yog qhov txawv ntawm Qib A, Qib B, thiab Qib D shipbuilding steel?
Qib A tsis muaj kev lav phib xaub toughness (kuaj tsis tas yuav tsum tau) thiab qis manganese cov ntsiab lus; haum rau cov uas tsis yog - tseem ceeb tha xim sab hauv cov climatic tej yam kev mob.
Qib B yuav tsum tau Charpy V- qhov ntsuas qhov cuam tshuam ntawm 0℃(32℃F) thiab muaj manganese ntau dua (Ntau dua lossis sib npaug li 0.80%) kom zoo dua deoxidation thiab grain refinement; zoo tagnrho rau kev tsim vaj tsev nyob rau hauv temperate thiab ntug dej hiav txwv.
Qib D yuav tsum muaj kev ntsuam xyuas qhov cuam tshuam ntawm -20℃(-4℃F) thiab muaj qhov zoo tshaj qhov kub thiab txias; pom zoo rau cov nkoj dej khov hauv chav dej, cov chaw ua haujlwm sab nrauv, thiab thaj chaw arctic.
Rau feem ntau kev lag luam shipbuilding nyob rau hauv nruab nrab huab cua, Qib B muab tus nqi zoo tshaj - kev ua tau zoo tshuav nyiaj li cas.
02.Cov ntawv pov thawj dab tsi koj muab rau Qib B shipbuilding steel daim hlau?
03.Koj puas tuaj yeem ua cov ntawv qib B rau qhov ntau thiab tsawg lossis ntxiv cov kev kho saum npoo?
Yog lawm. Peb muab ntau yam ntawm tus nqi - ntxiv cov kev pabcuam, suav nrog:
Nplaim / Plasma txiav rau koj qhov ntev
Beveling (ib zaug lossis ob lub bevel) rau kev npaj vuam
Drilling thiab xuas nrig ntaus
Txhaj tshuaj tua blasting (SA 2.5) thiab tiv thaiv-corrosion primer txheej (zinc-nplua nuj epoxy)
Kev kuaj ultrasonic (UT) thiab Z- kev ntsuas kev taw qhia (Z15–Z35)
Cov kev pabcuam no txo koj ntawm - lub sijhawm tsim khoom ntawm qhov chaw thiab xyuas kom npaj tau-- siv cov ntaub ntawv thaum xa khoom.
04.Dab tsi yog qhov tsawg kawg nkaus xaj kom muaj nuj nqis (MOQ) thiab lub sijhawm ua haujlwm rau Qib B shipbuilding daim hlau?
Peb tus qauv MOQ yog 10 tons rau kev txiav txim mus sib hais, nrog cov nqi txo nqi ntau dua rau cov thawv xa khoom (20+ tons). Rau cov qauv loj (piv txwv li, 20mm × 2000mm × 6000mm), peb khaws cia hauv - cov khoom muag thiab tuaj yeem xa tuaj hauv 7-10 hnub ua haujlwm. Rau kev cai thicknesses, kev kho cua sov (normalized, TMCP, QT), los yog thib peb -kev tshuaj ntsuam xyuas tog, thov tso cai rau 3-4 lub lis piam sij hawm ua khoom. Peb yog cov chaw tsim khoom nyob ze ntawm Qingdao thiab Shanghai chaw nres nkoj kom ntseeg tau tias kev xa khoom thoob ntiaj teb tau zoo.
