Lub zog tauj dua tshiab -Kev ua haujlwm tshwj xeeb

Siab -Tensile Structural Integrity:
Nrog rau qhov tsawg kawg nkaus lub zog ntawm 550MPa, Q550NH txhawb nqa lub teeb yuag tsim rau cua turbine yees thiab hnub ci mounting qauv, txo cov khoom siv los ntawm 30-40% piv rau qis dua -lub zog steels thaum tuav load{5}} bearing muaj peev xwm rau siab cua (Ntau tshaj los yog sib npaug rau 120km / h) 1.5 kPa). Qhov zoo -grained microstructure los ntawm thermo-mechanical controlled processing (TMCP) txhim khu kev qaug zog tiv thaiv, tseem ceeb heev rau cua turbines raug rau cyclic loading tshaj 20+ xyoo.

Tsawg-Txhim kho Corrosion Resistance:
Cov hlau alloy's Cu, Cr, thiab Ni ntxiv txhawb kev tsim kom ruaj khov, tus kheej - kho xeb txheej (sau ntawm FeOOH thiab alloy oxides) uas ua raws li lub ntuj thaiv tiv thaiv cov dej noo thiab corrosive ions. Nyob rau hauv ib puag ncig cua / hnub ci ib puag ncig (nyob deb nroog, ntug hiav txwv dej, lossis siab- qhov siab), tus nqi corrosion raug txo mus rau 1/3-1/5 ntawm cov pa roj carbon zoo tib yam, tshem tawm qhov xav tau ntawm cov txheej txheem tiv thaiv thiab tshuaj xyuas txhua xyoo. Kev ntsuas ntsev pos huab (ASTM B117) lees paub tias tsis muaj kev puas tsuaj rau cov substrate tom qab 1,000 teev, kom ntseeg tau ntev -lub sij hawm kev ua tau zoo nyob rau hauv seaside photovoltaic liaj teb los yog offshore cua tej yaam num.

 

Environmental Adaptability:

Kub Resilience: Khaws -40℃cuam tshuam toughness, qhov tseem ceeb rau huab cua txias huab cua ua liaj ua teb (xws li, sab qaum teb Europe, Inner Mongolia) qhov twg muaj kev pheej hmoo ntawm pob txha tawg.

UV & Oxidation Resistance: The dense rust layer stabilizes under UV exposure, preventing spalling and maintaining protective properties for decades.

 

Fabrication & Installation Advantages

Weldability: Tsawg carbon sib npaug (CE Tsawg dua lossis sib npaug li 0.42%) tso cai rau kev sib txuas ntawm ntauwd ntu thiab hnub ci brackets siv cov txheej txheem txheej txheem. Pom zoo Ni/Cu-cov kabmob electrodes kom ntseeg tau cov hlau corrosion kuj (atmospheric corrosion indexINtau dua lossis sib npaug rau 6.2) thiab sib piv cov khoom siv kho tshuab, txo cov nqi xa ntawv -weld tshuaj xyuas.

Formability: Muaj nyob rau hauv nyias gauges (2.0mm–60mm), cov hlau accommodates complex geometries rau hnub ci trackers thiab cua ntauwd flanges, nrog zoo ductility (Ntau tshaj los yog sib npaug rau 15% elongation) rau txias dabtsi yog khoov thiab yob- sib sau.

 

Daim phiaj siv

Cua Zog:

Turbine Ntauwd: High-cov ntu muaj zog txo cov hnyav ntauwd, ua kom cov qauv siab dua (Ntau dua lossis sib npaug li 150m hub qhov siab) nrog cov nqi txhim kho- ua haujlwm tau zoo.

Nacelle Cheebtsam: Corrosion- tiv thaiv cov hlua khi thiab cov ntaub thaiv npog rau cov tshuab hluav taws xob, ua kom muaj ntsev ruaj khov- cov huab cua nyob hauv ntug dej hiav txwv lossis plua plav hauv av.

Hnub Ci Zog:

Mounting Structures: Lub teeb yuag hnub ci vaj huam sib luag thav duab thiab trackers, tiv thaiv xeb hauv suab puam (siab-kub, qis-} av qeeg) lossis chaw sov (siab- dej nag) huab cua) yam tsis muaj xim.

Inverter Enclosures: Tus kheej-cov ntawv tiv thaiv rau cov khoom siv hluav taws xob sab nraum zoov, txo kev saib xyuas hauv tej thaj chaw deb hnub ci.

Environmental & Economic tus nqi

Sustainability Alignment: Xim -dawb tsim txo lub neej voj voog VOC emissions los ntawm 90%, ua raws li lub zog tauj dua tshiab qis - cov hom phiaj carbon (xws li IEC 61400-22 rau cua turbine sustainability).

Nqi Efficiency: Tsawg txij nkawm (tsis muaj repainting, tsawg dua kev soj ntsuam) txo tus nqi lifecycle los ntawm 50% piv rau cov hlau coated, nrog rau lub neej kev pab ntau tshaj 30 xyoo- sib phim lub neej ntawm cov cua turbines thiab solar panels.

Kev txuag nyiaj txiag: Siab zog-rau- qhov hnyav piv txo qis kev thauj mus los thiab kev teeb tsa lub zog, tseem ceeb rau tej thaj chaw deb txuas ntxiv dua tshiab.

Kev Ua Raws Cai & Kev Pov Hwm Zoo

Txhua batch tau txais kev sim nruj rau:

 

Cov khoom siv kho tshuab (tensile, cuam tshuam, elongation) kom ua raws li GB / T 4171-2008.

Corrosion resistance ntawm atmospheric exposure tests (piv txwv li, ISO 9223), lees paub corrosion poob<1mm over 100 years.

 

Hauv kev xaus, Q550NH steel redefines cov khoom ua tau zoo rau kev siv cua thiab hnub ci, muab cov pov thawj ua ke ntawm lub zog tensile siab, tus kheej - tiv thaiv durability, thiab qis - tu tsim. Kev tsim kho rau cov kev nruj ntawm cov khoom siv hluav taws xob tauj dua tshiab, nws ua rau muaj kev ruaj ntseg, nqi- cov kev daws teeb meem zoo uas tiv taus qhov teeb meem hnyav tshaj plaws thaum txhawb kev hloov pauv thoob ntiaj teb mus rau lub zog huv.
