A75 rails puas tuaj yeem ua lub taub hau- tawv?
Yog lawm,A75 kabtuaj yeem ua tau taub hau- tawv. Cov txheej txheem no yog ib qho kev xaiv rau A75 crane rails kom ntev lawv lub neej hnav nyob rau hauv cov ntsiab lus ntawm lub log, xws li hauv cov chaw nres nkoj thiab cov ntawv thov hnyav. Lub taub hau - hardened A75 rails feem ntau siv cov khoom xws liua 71mnsteel kom ua tau siab dua hardness thiab nce hnav tsis kam.
qhov zoo ntawm lub taub hau- kho hardening rau DIN 536 A75 crane ntsia
Lub taub hau- hardening kev kho mob rau DIN 536 A75 crane rails muab superior hnav tsis kam, ncua kev pab cuam lub neej, thiab txo nqi txij nkawm, ua rau nws zoo tagnrho rau hnyav-lub luag hauj lwm, siab-frequency industrial puag ncig. Los ntawm kev ua kom lub ntsej muag hardness ntawm lub taub hau tsheb ciav hlau mus txog kwv yees li340-380 HB(piv rau 260HB rau cov qauv kev sib tw), qhov kev kho mob no txhim kho kev ua haujlwm ntawm cov yas deformation, xws li corrugation thiab crushing, thaum tuav lub ductile, tawv, thiab ruaj khov.
- Tseem ceeb Extended Service Life:Lub taub hau- tawv A75 rails tuaj yeem mus txog50%ntev dua nyob rau hauv nkhaus thiab siab - hnav daim ntaub ntawv, xws li chaw nres nkoj, steelworks, thiab logistics hubs.
- Superior Wear thiab Fatigue Resistance:Cov txheej txheem, uas suav nrog kev kho cua sov, tsim kom muaj zog pearlite lossis martensite microstructure (feem ntau mus txog 15mm qhov tob), txo qis hnav los ntawm kwv yees li.20-30%piv rau cov pa tsheb ciav hlau.
- Tus nqi qis dua ntawm cov tswv cuab:Txawm tias tus nqi pib yog25-30%siab dua, qhov txo qis ntawm kev hloov pauv thiab kev saib xyuas qis dua ua rau nws raug nqi ntau dua -zoo rau hnyav- cov xwm txheej thauj.
- Txo Rail Deformation:Lub hardened nto resists nto qaug zog, xws li shelling, spalling, thiab corrugation, uas ua kom smoother crane khiav lag luam thiab tsis tshua muaj kev sib tsoo.
- Siab Load-Bearing Capability:Txoj kev kho A75 rail, feem ntau yog tsim los ntawm siab - lub zog steel (xws li, U71Mn), muaj kev txhim kho lub zog los txhawb nqa hnyav -lub luag haujlwm, 50-100+ tuj cranes.
GNEE RAILsiv cov txheej txheem siab tshaj hauv -kab induction hardening thev naus laus zis los muab kev tswj xyuas meej ntawm qhov tob thiab qhov sib xws ntawm txheej tawv tawv ntawm txhua qhov Profile A75 rail. Peb cov txheej txheem tsim khoom ua kom ntseeg tau tias thaj chaw hloov pauv ntawm lub taub hau tawv thiab tus qauv - lub vev xaib muaj zog yog seamless, tiv thaiv kev ntxhov siab sab hauv uas tuaj yeem ua rau kev ua haujlwm tsis zoo. Los ntawm kev tswj hwm kev kho cua sov hauv -tsev, peb tuaj yeem hloov kho A75 rail khoom hardness kom tau raws li cov kev cai tshwj xeeb ntawm cov dej num hnyav crane rail tej yaam num, xws li tus qauv 260 HB mus rau premium 340 HB los yog siab dua.
Cov khoom sib xyaw thiab Hardness Qib ntawm DIN 536 A75 rail
DIN 536 A75 rail yog ib qho tshwj xeeb hnyav - lub luag haujlwm crane rail tsim los ntawm German cov qauv, feem ntau siv rau qhov chaw nres nkoj, davhlau ya nyob twg, thiab kev lag luam crane. Nws feem ntau tsim los siv siab -lub zog steel qib zoo li700A (50Mn)los yog900A (U71Mn), tsim los tiv taus siab dynamic loads, nrog tus qauv tensile lub zog ntawm ntau dua los yog sib npaug rau 880N / mm².
