Q: Quenched thiab tempered (quenching + tempering)

① Lub teeb hnyav hnyav

Txo cov khoom siv los ntawm 20-30% nyob rau hauv tib lub zog, txiav boom hnyav los ntawm 15-20%

Lub teeb ncaj ncaj txhais raulifting peev ntau duathiabntev ua hauj lwm vojvoog

Txo qhov hnyav tso cai rau cov tshuab hydraulic me me thiab qhov hnyav dua, ntxiv kom txo qis tag nrho kev siv zog

② Zoo sib npaug ntawm lub zog thiab Toughness

Lub zog tawm los mus txog 890MPa, 2.6 npaug ntawm cov qauv hlau zoo tib yam (S355)

Zoo heev qaug zog tsis kam, haum rau cyclic load tej yam kev mob ntawm cranes

Khaws ntau dua lossis sib npaug rau 30J cuam tshuam rau qhov hnyav ntawm -20℃qis kub, tiv thaiv kev tawg tawg

③ Kev tsim qauv tsim kom zoo

Tso cai ntau dua compact boom seem thiab kev sib txuas tsim

Txo cov seem boom, ua kom yooj yim cov qauv thiab txhim kho kev ntseeg tau

Yooj yim rau kev tsim cov loj-span, ultra-loj-tonnage cranes

S890Q steel yog tsuas yog siv nyob rau hauv lubsiab -stress qhov tseem ceebCrane booms:

Domestic Equivalent Steels:

Q890D (kev cuam tshuam loj dua lossis sib npaug rau 34J / -20 degree), qhov pib sib npaug rau S890Q

Q890E (kev cuam tshuam loj dua lossis sib npaug rau 34J / -40 degree), sib npaug rau S890QL

Q1: S890Q steel phaj yog dab tsi?

A: S890Q yog lub siab - lub zog steel phaj raws li EN 10025-6, muab nyob rau hauv quenched thiab tempered (Q) mob, nrog rau qhov tsawg kawg nkaus yield zog ntawm 890 MPa.

Q2: Cov khoom siv ntawm S890Q yog dab tsi?

A: Cov khoom siv European rau S890Q yog 1.8940.

Q3: Puas yog S890Q suav tias tsis yog- hlau alloy?

A: Yog. Raws li EN kev faib tawm, S890Q tau teev npe tias tsis yog- alloy cov qauv hlau, txawm hais tias me me alloying ntsiab tau ntxiv rau lub zog thiab kev tswj kom nruj.

Q4: Dab tsi thickness ntau yog muaj rau S890Q steel phaj?

A: Cov khoom siv dav dav dav li ntawm 6 hli txog 150 hli, nyob ntawm lub peev xwm zeb thiab cov qauv yuav tsum tau ua.

Q5: Dab tsi yog cov khoom siv kho tshuab ntawm S890Q?

A:

Yield zog: Ntau dua lossis sib npaug rau 890 MPa (tsawg dua lossis sib npaug li 50 mm)

Tensile zog: 940-1100 MPa

Elongation: Ntau dua lossis sib npaug li 11%

Impact test: Ntau dua lossis sib npaug rau 30 J ntawm −20 degree

Q6: S890Q steel puas tuaj yeem welded yooj yim?

A: Yog, S890Q muaj qhov zoo weldability, tab sis vuam yuav tsum ua raws li cov txheej txheem tswj, suav nrog cov khoom siv hluav taws xob kom zoo, preheating (yog tias xav tau), thiab cov ntaub ntawv muab tub lim tsim nyog.

Q7: Qhov txawv ntawm S890Q thiab S890QL yog dab tsi?

A: S890QL muaj qhov zoo dua qis- qhov kub thiab txias cuam tshuam qhov hnyav dua li S890Q thiab feem ntau tau teev tseg rau qhov chaw txias dua lossis cov qauv tseem ceeb.
