Lub Zog & Siab Nkoj:Penstocks, kauv rooj rau cov nroj tsuag fais fab, thiab ruaj khov los yog thauj cov tso tsheb hlau luam.
Tus nqi ntawm S890Q steel phaj yog qhov sib txawv heev thiab kim kim dua li qis dua - qib siab - lub zog steels zoo li S690Q. Tsis muaj tus nqi lag luam ruaj khov, tab sis cov ntsiab lus tseem ceeb hauv qab no thiab kev kwv yees muab kev taw qhia:
Tus nqi tseem ceeb tsav tsheb:
Order Specifications:
Thickness & Dimensions:Nqe nce ntau nrog tuab. Cov phaj siab tshaj 50-60 hli tuaj yeem yog 50-100% kim dua ib tuj dua li daim hlau nyias (xws li 10 hli).
Ntim:Kev txiav txim loj tonnage (piv txwv li, tag nrho cov tsheb thauj khoom lossis kev txiav txim zeb) tau txais cov luv nqi tseem ceeb.
Ntawv pov thawj:Standard EN 10204 3.1 ntawv pov thawj suav nrog. Qhov thib peb ntxiv -kev xeem tog (piv txwv li, Lloyd's, DNV) lossis kev kuaj tshwj xeeb ntawm -60℃ntxiv tus nqi.
Kev ua lag luam Factors:
Raw Material & Energy Costs:Alloying cov ntsiab lus (Ni, Cr, Mo) thiab lub zog-ntaus quenching/tempering ua rau cov nqi rhiab rau cov khoom lag luam thiab lub zog.
Supply & Demand:Ua los ntawm ib tug tsawg tus naj npawb ntawm cov mills tshwj xeeb (xws li, Dillinger, SSAB, voestalpine), yog li muaj thiab kev sib tw hauv cheeb tsam cuam tshuam rau tus nqi.
Kev Ua Haujlwm & Logistics:
Kev ua:Txiav, drilling, lossis kev npaj ntug ntxiv tus nqi.
Kev xa khoom:Qhov chaw, shipping txoj kev, thiab Incoterms (xws li, EXW, FOB, xa) yog ib feem tseem ceeb ntawm tus nqi kawg.
Tus nqi kwv yees (Rau kev taw qhia nkaus xwb):
S890Q feem ntau raug nqi 50-150% ntau dua S690Q vim nws cov chemistry ntau dua thiab ua tiav.
Tus nqi qis Ib Metric Ton: Kwv yees li € 2,000 - € 4, 000+ (los yog sib npaug hauv USD / GBP).
Qeb kawg: Loj - ntim xaj ntawm nruab nrab- cov phaj tuab.
Upper end: Low-volume, very thick plates (>80 mm), cov txiav me me, lossis kev txiav txim yuav tsum muaj ntawv pov thawj tshwj xeeb.
Yuav Ua Li Cas Tau Txais Qhov Tseeb Quote:
Muab cov neeg xa khoom nrog cov ncauj lus kom ntxaws Thov rau Quotation (RFQ) suav nrog:
Cov khoom siv qib: EN 10025-6 S890Q (qhia cov qib qis yog tias xav tau, piv txwv li, S890QL rau -40℃toughness).
Qhov Loj: Thickness × Dav × Length (in mm).
Quantity: Tag nrho qhov hnyav los yog pes tsawg daim hlau.
Yuav tsum tau ntawv pov thawj.
Kev xav tau kev ua haujlwm (yog tias muaj).
