Dab tsi yog qhov txawv ntawm S690QL thiab S960QL?

Qhov txawv tseem ceeb yog qhov ntawdS960QL muaj qhov ua tau zoo dua qhov qis tshaj tawm lub zog (960 MPa) piv rauS690 QL (690 MPa ua), faib S960QL ua ib qho ultra-siab-lub zog steel. Qhov no ua rau S960QL zoo tagnrho rau cov ntawv thov uas xav tau lub zog loj tshaj plaws - rau - qhov hnyav piv, thaum S690QL yog siab - lub zog steel siv qhov kev xav tau siab, tab sis S960QL lub zog tsis xav tau. Ob leeg yog quenched thiab tempered steels uas tsim los ntawm cov txheej txheem TMCP, muaj cov tshuaj zoo sib xws nrog microalloying ntsiab, thiab yog tsim los rau zoo weldability thiab toughness.

Ob lub steels txais yuavQuenched + Tempered (Q + T)txheej txheem, tab sis nrog txawv tshwj xeeb parameter:

s960 qw:

quenching kub: 880-920 degree

Tempering kub: 580-640 degree

Ua kom zoo dua tempered martensite qauv kom ua tiav ultra-lub zog siab

S690 qw:

quenching kub: 890-930 degree

• Heavy Machinery thiab Khoom Siv:Lub zog -rau- qhov hnyav piv yog qhov zoo dua, ua rau lawv tsim nyog rau kev tsim cov tshuab zoo heev xws li cranes, mining machinery, thiab ntau ntxiv.

• Choj thiab Infrastructure:Lub zog zoo tshaj plaws thiab kev tiv thaiv corrosion ua rau cov ntaub ntawv no zoo heev rau kev tsim kho, nrog rau kev tsim choj thiab lwm yam kev tsim kho vaj tse.

• Automotive thiab Tsheb thauj mus los:Lub zog siab thiab zoo formability ua rau kev tsim khoom los tsim lub teeb yuag, siab -kev ua haujlwm ntawm tsheb thiab tsheb thauj mus los.

Muab qhov tseem ceeb S960QL hauv cov xwm txheej hauv qab no:

• Kev tsim qauv tsim nyogtshaj 30% poob phausthaum tuav lub siab load-cov kabmob muaj peev xwm
• Kawm paub txogcyclic hnyav loads(piv txwv li, loj crane booms, offshore platforms)
• Cov qauv tseem ceeb ua haujlwm hauvultra- qhov kub thiab txias ib puag ncig(hauv qab -50 degree)
• Cov khoom thickness yog nruj me ntsis txwv tab sis lub zog yuav tsum tau muaj siab heev
• Tub rog lossis aerospace cov qauv nrog cov kev cai tshwj xeeb rauqaug zog lub neej
• Cov phiaj xwm uas muaj peev nyiaj txaus nrhiav kev txwv kev ua haujlwm rau siab - khoom siv kawg

Ua ntej S690QL hauv cov xwm txheej hauv qab no:

• Pa engineering machinery thiab tsheb cov qauv nrog lub zog yuav tsum tau ntawm 690MPa qib
• Cov ntawv thov kev lag luam dav dav nrog cov peev nyiaj tsawg tab sis tseem xav tau lub zog siab
• Cov kev xav tau siab rau kev ua thiab vuam yooj yim
• Qhov hnyav ntawm tus qauv tsis yog ib qho kev txiav txim siab loj
• Loj - ntim khoom nrog kev tswj tus nqi tseem ceeb
• Kev tsim vaj tsev dav dav thiab cov qauv choj yam tsis muaj kev xav tau ib puag ncig
