1. Kev ua haujlwm
Kev ua haujlwm S890QL1 yuav tsum tau ua raws li nws cov quenched thiab tempered (Q + T) lub xeev los tiv thaiv qhov poob ntawm nws 890 MPa yield zog.
Vuam: Nws yog welded heev tab sis rhiab rau cua sov. Preheating rau 150-250℃feem ntau xav tau rau cov phaj tuab kom tsis txhob muaj qhov txias txias. Kev siv cov khoom siv hydrogen tsawg (HD < 5ml / 100g) yog qhov tseem ceeb los tswj kom muaj kev ncaj ncees ntawm Heat Affected Zone (HAZ).
Txiav : Haum rau thermal txiav txoj kev xws li laser, plasma, thiab oxy- roj. Laser- pab tsim thiab txiav txiav yog nce siv nyob rau hauv 2026 los xyuas kom meej nruj dua kam rau ua.
Cold forming : Txawm hais tias nws muaj zog heev, nws muaj kev kho tau zoo dua. Yam tsawg kawg bending radii feem ntau yog 3x mus rau 4x lub phaj thickness kom tsis txhob nto tawg.
Machining (机加工: Vim lub hardness siab, carbide-tipped cov cuab yeej thiab ruaj khov, nruj kev teeb tsa yog tsim nyog los tiv thaiv cov cuab yeej hnav thiab ua hauj lwm hardening.
2. Cov ntawv thov
S890QL1 yog siv rau hauv kev xav tau ntawm kev thauj khoom-cov kabmob ib puag ncig uas txo qhov hnyav thiab txias- huab cua ruaj khov yog qhov tseem ceeb.
Lifting & Thauj: Mobile crane booms, aerial platforms, thiab derrick qauv. Nws tso cai rau ntev dua crane mus txog thiab ntau dua payloads ntawm hnyav - lub luag haujlwm tsheb chassis.
Mining & Kev Tsim Kho: Dipper sticks thiab thoob cov khoom rau excavators, thiab cov qauv kab teeb rau siab -nce skyscrapers.
Offshore & Zog: Penstocks, lub nkoj siab, thiab offshore platforms uas ua haujlwm nyob rau hauv Arctic tej yam kev mob, raws li nws tuav nruj mus rau -60 degree.
Infrastructure : Kev siv ntau ntxiv hauv siab - thauj khoom txuas txuas thiab ntsuab -lit pipeline project rau xyoo 2026.
3. Qhov zoo
Tus nqi tseem ceeb ntawm S890QL1 yog nyob rau hauv nws cov efficiency thiab huab ib puag ncig kuj.
Qhov hnyav txo: Nws lub zog tawm los yog kwv yees li 30% siab dua S690QL, ua rau cov kws ua haujlwm siv cov phaj nyias nyias. Qhov no txo qhov hnyav tag nrho ntawm cov qauv txog li 40% piv rau cov pa hlau.
Tsis tshua muaj siab heev-Temperature Toughness: Tsis zoo li tus qauv "Q" lossis "QL" qib, qhov "L1" tsim tau lees tias muaj kev cuam tshuam lub zog tiv thaiv ntawm qhov kub thiab txias li -60 degree, ua rau nws muaj kev nyab xeeb dua rau kev siv polar thiab qhov siab siab.
Tus nqi-Kev ua tau zoo: Txawm hais tias tus nqi pib ntawm cov khoom siv siab dua, "leaner build" txo cov kev xav tau ntawm lub hauv paus, cov nqi tsheb thauj mus los, thiab tag nrho lub sijhawm vuam, ua rau txo qis tag nrho cov nuj nqis.
Predictable Performance: Niaj hnub nimno manufacturing (xws li Strenx® 900 F) muab nruj flatness thiab tuab tolerances, kom ntseeg tau precision nyob rau hauv automated prefabrication.
