Hlau Phaj

Cov phaj hlau yog lub tiaj tus- dov hlau ntawv tuab dua 4 hli, siv rau hauv kev tsim, nkoj tsim, lub nkoj siab, kav dej, thiab kev siv hauv kev lag luam. Nyob ntawm cov khoom siv- carbon steel, stainless hlau, lossis hlau alloy- steel phaj muab lub zog, durability, thiab formability yuav tsum tau rau qhov hnyav ib puag ncig. Cov kev sib txawv muaj xws li cov ntawv carbon steel, stainless hlau phaj, nkoj phaj (rau marine propulsion & hulls), pipeline steel phaj, thiab hnav- cov hom phaj resistant xws li Hardox 500.

• Carbon Steel Sheet / Phaj: Common low alloy lossis me steels; tuab daim hlau 5-200 mm +
• Stainless hlau phaj: Feem ntau 304, 316, 316L, duplex, thiab lwm yam.; Kev xaiv qhov chaw tiav (pickled, #4, BA, thiab lwm yam)
• Nkoj PhajAH36 / DH36 / EH36-siab yield zog nrog toughness ntawm qis kub rau marine cuam tshuam & qaug zog
• Hnav phajHardox 500 thiab lwm yam.-siab hardness (Ntau dua los yog sib npaug rau 500 HBW) thiab cuam tshuam toughness rau hnav & puas
• Coated / Kho Phaj: Galvanized steel phaj (zinc coated), ua ntej-painted, txiav & edged daim hlau

• Melting & Casting- Steelmaking ntawm EAF lossis BOS; nruam casting rau hauv slabs.
• Kub Rolling- Slabs rhaub rau ~ 1,100-1,300 degree, ntxhib thiab tiav dov rau phaj tuab.
• Normalizing, quenching & tempering- Tshwj xeeb tshaj yog rau nkoj phaj thiab hnav phaj kom ua tiav lub zog thiab toughness.
• Txias Rolling / Phaj Flattening- Rau txias dov los yog phaj Tshuag uas yuav tsum tau nruj dua flatness thiab nto tiav.
• Kev kho saum npoo- Pickling, galvanizing, polishing, txhaj tshuaj blasting.
• Txiav / Ntug / Shearing- Kev cai ntau thiab tsawg: cuttings, nested daim hlau, ntug npaj.
• Kev Tshawb Fawb & Kev Xeem:

1. Mechanical tests: tensile, yield, elongation, impact (Charpy V-notch)
2. Kev ntsuas hardness rau hnav daim hlau
3. Ultrasonic thickness / tsis zoo tshuaj xyuas
4. Kev tshuaj ntsuam xyuas muaj pes tsawg leeg
5. Dimensional kam rau ua (flatness, thickness uniformity)

• Yield & Tensile zog: Nkoj daim hlau zoo li AH36 / DH36 muaj qhov tsawg kawg nkaus tawm los (Ntau dua lossis sib npaug ntawm 355 MPa) thiab lub zog tensile zoo rau cov khoom siv marine.
• Toughness ntawm Tsawg Kub: EH36 yog tsim rau huab cua txias; qhov cuam tshuam kev ua tau zoo yog qhov tseem ceeb.
• Abrasion Resistance: Hnav daim hlau (xws li Hardox 500) muab cov tawv tawv nrog cov tawv tawv kom tiv thaiv kev tawg hauv qhov cuam tshuam loj.
• Corrosion Resistance: Stainless hlau daim hlau thiab galvanized steel daim hlau tiv thaiv xeb; pipelines thiab cia yuav tsum tau resistant steel.
• Formability / Weldability: Carbon steel phaj (A36) yooj yim rau vuam thiab daim ntawv; nkoj daim hlau muaj cov kev cai tshwj xeeb rau vuam, dabtsi yog khoov thiab lwm yam.

• Shipbuilding & Marine Kev Tsim Kho: Hulls, decks, bulkheads, offshore rig platforms siv AH36 / EH36 / DH36.
• Cov Khoom Siv Hluav Taws Xob & Boilers: Siv ASTM A516 daim hlau ntawm cov qib tsim nyog qhov chaw siab thiab kub yog qhov tseem ceeb.
• Cov qauv steel ua haujlwm: Cov tsev, txuas hniav, ncej-ASTM A36 phaj siv dav.
• Hnav Parts / Mining / Heavy Machinery: Hardox 500 thiab cov phaj zoo sib xws hauv cov loaders, cov tsheb thauj khoom pov tseg, chutes, liners.
• Pipeline & Roj & Gas: Pipeline steel phaj rau txoj kab uas hla loj, qee zaum nrog cov txheej txheem, siv nyob rau hauv compressor chaw nres tsheb lossis trenchless crossings.
• Kho kom zoo nkauj / Architectural: Stainless hlau daim hlau, txhuam los yog polished, rau cladding, facades.

• Siab zog thiab toughness: Marine-qib thiab siab- cov nkoj nkoj ua haujlwm hnyav thiab ib puag ncig hnyav.
• Durability: Hnav daim hlau txuas ntxiv lub neej nyob rau hauv kev puas tsuaj; galvanized phaj tiv thaiv corrosion.
• Versatility nyob rau hauv Loj & Thickness: From thin sheets (cold-rolled) to very thick plates (>200 mm) rau cov qauv hnyav lossis hnav daim ntaub ntawv.
• Weldability thiab Fabrication: Ntau qib tsim los rau kev vuam zoo, khoov, thiab txiav kev ua haujlwm.
• Kev kho kom haum: Cuttings, pre- txiav cov duab, ntug prep, txheej los yog galvanizing muaj nyob rau hauv specification.

Thaum qhia txog steel phaj, xav txog:

• Hlau qib + tus qauv (xws li AH36, A36, A516)
• Thickness, dav, ntev, flatness kam rau ua
• Nto tiav & kho (galvanized, stainless polish, hnav phaj, thiab lwm yam)
• Ntug hom (sheared, nplaim taws txiav, zeb ntug)
• Kev sim yuav tsum tau (mechanical, cuam tshuam, hardness, UT)
• Quantity thiab shipping lub sij hawm
