Qhov txawv ntawm S690QL thiabS690 QL 1Cov lus dag tshwj xeeb hauv lawv qhov yuav tsum tau muaj kev cuam tshuam toughness ntsuas kub, raws li tau hais los ntawm European tus qauv EN 10025-6.
Ntawm no yog qhov tseeb, concise breakdown:
Core Sib txawv: Kev ntsuas kub rau qhov cuam tshuam Toughness
Ob qib yog zoo ib yam ntawm cov tshuaj muaj pes tsawg leeg, qhov tsawg kawg nkaus yield zog (690 MPa), tensile zog ntau yam, thiab covQuenched & Tempered (QL)kev tsim khoom. Cov"1"lus inQL1qhia aqis dua (txias) ntsuas kub.
| Feature | S690 qw | S690 QL 1 |
|---|---|---|
| Impact Test Temperature | -40 degree | -60 degree |
| Yam tsawg kawg nkaus zog | 27 Joules (Charpy V-ntiv) | 27 Joules (Charpy V-ntiv) |
| Tag nrho Lwm Cov Khoom | Zoo tib yam (Yield Strength, Tensile, Chemical Comp.) | Zoo ib yam |
Cov kev cuam tshuam rau kev xaiv
Qhov kev xaiv ntawm QL thiab QL1 yog tsav los ntawm qhov ntsuas kub qis tshaj qhov kev tivthaiv yuav tau ntsib hauv nws lub neej ua haujlwm.
Xaiv S690QL:Rau cov ntawv thov uas cov qauv yuav ua haujlwm hauv huab cua txias, tab sis tsis yog huab cua Arctic. Kev tsim kub ntawm -20℃rau -40℃yog qhov raug. Piv txwv li: Mobile cranes rau European lub caij ntuj no qhov chaw, dav dav machinery hnyav.
Xaiv S690QL1:Rau cov ntawv thov uas tau lees tias raug rau qhov tsis tshua muaj kub. Kev tsim kub ntawm -40℃rau -60℃lossis qis dua. Piv txwv:
Offshore cov qauv hauv Arctic (North Hiav Txwv, Barents Hiav Txwv).
Cov cuab yeej siv rau mining lossis roj & roj ua haujlwm hauv Siberia, Canada, lossis Alaska.
Cheebtsam raug rau cryogenic nchuav los yog tub yees.
Qhov tseem ceeb lifting iav ntawm cov hlab ntsha ua haujlwm hauv cov dej polar.
Vim Li Cas Qhov Kev Sib Txawv Ntawm Qhov Teeb Meem: Kev Tiv Thaiv Kev Txhaum Cai
Hlau ua rau cov pob txha tawg (dhau, kev puas tsuaj tsis zoo nrog cov yas deformation me ntsis) raws li qhov kub thiab txias. Qib "QL1" tau lees paub tias cov khoom tau raug sim thiab ua pov thawj kom tuav tau qhov tsawg kawg nkaus ntawm qhov hnyav (27J) ntawm qhov kub qis dua, muab qhov kev nyab xeeb loj dua los tiv thaiv kev tawg hauv qhov chaw huab cua.
Kev Muag Khoom & Daim Ntawv Pov Thawj
Thaum txiav txim, koj yuav tsum qhia qhov tseeb qhov tseeb. Daim ntawv pov thawj zeb xeem yuav qhia meej txog cov txiaj ntsig ntawm qhov ntsuas qhov xav tau (-40℃rau QL, -60℃rau QL1). Nws yog qhov tseeb thiab yuav tsum tau ua ib feem ntawm cov ntaub ntawv pov thawj.
Hauv cov ntsiab lus:
S690QL thiab S690QL1 yog ob qib sib cais los ntawm lawv lub qhov rais ua haujlwm kub. QL1 yog "Arctic-qib" version ntawm S690QL, muab lub zog zoo tib yam tab sis lav qhov tawv tawv ntawm qhov kub qis dua rau cov frigid thiab siab tshaj - daim ntawv thov cov ceg txheem ntseeg.
