daim ntawv thov
Tsheb thauj mus los hnyav
S690QL yog dav siv nyob rau hauv bulldozers, pob tseg tsheb, articulated haulers, trailer ncej, thiab tshwj xeeb tsheb. Nws lub zog siab tso cai rau kev txo qhov hnyav, uas ncaj qha nce lub peev xwm thauj khoom thiab txhim kho roj efficiency, ua rau nws zoo tagnrho rau hnyav- daim ntawv thov kev thauj mus los.
Lifting & Kev tsim khoom siv
Nws yog cov khoom siv zoo tshaj plaws rau crane booms, jibs, forklift thav duab, hydraulic caj npab, thiab kev txhawb nqa rau cov tshuab loj loj. S690QL muab lub zog siab thiab tawv uas xav tau los tuav cov khoom hnyav, thaum tseem pab txo qhov hnyav tag nrho ntawm cov khoom siv.
Cov qauv hlau
Hauv kev tsim vaj tsev hauv pej xeem, S690QL yog siv rau cov khoom tseem ceeb hauv kev txuas hniav, siab -cov tsev nce siab, chaw ntau pob, thiab cov chaw sab nrauv. Nws lub zog siab ua rau cov engineers tsim cov qauv tsim nrog tsawg dua kev txhawb nqa thiab kev ncua ntev, ua rau muaj txiaj ntsig zoo thiab kev lag luam tsim.
Tshuab Tsev
Nws yog feem ntau siv rau cov thav duab thiab cov khoom siv hauv cov tshuab ua haujlwm uas yuav tsum tiv taus kev qaug zog thiab kev ntxhov siab rau lub neej ntev. Kev sib xyaw ua ke ntawm lub zog thiab tawv tawv pab txhim kho kev ntseeg tau thiab kav ntev ntawm cov khoom siv.
Mining & Fais fabS690QL kuj tseem siv rau hauv cov khoom siv mining, cov qauv tsim hluav taws xob, thiab qee yam ntawm cov hlab ntsha siab. Nws muaj peev xwm tiv taus cov khoom hnyav thiab kev ua haujlwm hnyav ua rau nws haum rau cov kev xav tau no.

Dab tsi yog qhov sib npaug rau S690QL steel?
ASTM A514, EN 10149-2 Qib S700MC, AS / NZS 3579 Qib 700, AM 700, Bisalloy 80.
Dab tsi yog qib S690QL khoom?
S690QL yog lub zog siab quenched thiab tempered steel qib uas ua raws li cov lus qhia steel EN 10025. Qhov kev xaiv S690QL yog hais txog qhov tsawg kawg nkaus yield zog ntawm 690 MPa.
Tus nqi ntawm S690ql yog dab tsi?
₹ 130/KgS690 QL phaj yog siab - lub zog, quenched, thiab tempered steel phaj tsim los siv rau hauv cov qauv siv uas xav tau lub zog siab thiab zoo heev toughness.
Dab tsi yog qhov siab tshaj plaws thickness mus txog qhov twg S690QL tuaj yeem muab tau thaum tseem tswj hwm nws cov khoom siv kho tshuab?
S690QL feem ntau muaj nyob rau hauv thicknesses txog li 150 hli, tab sis qhov tseeb tshaj plaws nyob ntawm cov chaw tsim khoom thiab qhov yuav tsum tau muaj kev cuam tshuam toughness theem.
Lub creep kuj ntawm S690QL piv rau ntawm S500QL li cas, thiab qhov kev khiav hauj lwm kub txwv qhov no impose?
