Yam tsawg kawg Bending Radius: Feem ntau 2.5 mus rau 3.5 npaug ntawm phaj tuab nyob ntawm qhov kev taw qhia dov.
Kub txoj kev:
Yuav tsum zam ntawm qhov kub siab tshaj 600℃kom tsis txhob hloov cov cua sov-kho cov khoom.
Machining:
Nws tuaj yeem raug siv los siv cov qauv txheej txheem siv rau siab - steels muaj zog, muab qhov tsim nyog txias thiab siv cov cuab yeej ceev.
Qhov zoo
Qhov hnyav Efficiency:Nws qhov tsawg kawg nkaus 890 MPa lub zog tso cai rau cov neeg tsim qauv siv cov phaj nyias nyias, ua rau "leaner tsim" uas txo cov qauv hnyav tag nrho yam tsis muaj kev txi lub zog.
Nce Payload:Hauv kev thauj mus los, cov tsheb sib zog sib dua ncaj qha mus rau kev nqa nqa ntau dua rau cov khoom lossis cov khoom thauj.
Kub Kub Resistance:Qhov "L" hauv S890QL txhais tau hais tias lub siab tawv tawv ntawm qhov kub thiab txias mus rau-40 degree(thiab txawm tias qis dua rau ntau yam xws li QL1), ua rau nws haum rau Arctic lossis hnyav ib puag ncig.
Kev txuag nqi:Thaum tus nqi pib ib tuj siab dua, nws tuaj yeem txo tag nrho cov nqi ntawm qhov project los ntawm kev xav tau tsawg dua cov hlau thiab txo cov fabrication, tsheb thauj mus los, thiab cov nqi kho.
Fabrication yooj yim:Txawm hais tias nws cov tawv tawv, nws tseem yooj yim rau vuam thiab txias - daim ntawv piv rau lwm yam ultra- siab- cov ntaub ntawv muaj zog, muab cov txheej txheem preheating kom raug.
Cov ntawv thov tseem ceeb
S890QL feem ntau yog siv nyob rau hauv hnyav-cov haujlwm ua haujlwm uas txo qhov hnyav thiab siab load-cov kabmob muaj peev xwm tseem ceeb:
Lifting & Handling:Siv dav rau crane booms (mobile thiab loader), offshore cranes, aerial platforms, thiab hnyav -duty hydraulic systems.
