Daim ntawv thov ntawm JIS G310 SM490B carbon thiab qis - - lub zog steel phaj
Jis g310 Vim nws cov khoom siv sib npaug thiab kev tiv thaiv mus rau deformation, nws yog ib txwm xaiv rau qhov loj {4} ntsuas cov haujlwm thiab cov phiaj xwm kev xav tau.
Cov ntawv thov feem muaj xws li:
Choj tsim kev tsim:
SM490B yog zoo - ruited rau ntev- spail choj thiab tsa txoj kev loj. Nws cov txiaj ntsig zoo lub zog tso cai rau cov cuab yeej tsim tsim tau cov cuab yeej ua kom muaj zog dua qub, txhim kho thauj khoom khov kho thaum txo cov khoom hnyav. Cov hlau kuj tseem muaj cov qauv zoo, pab tau cov tshuab hluav taws xob, kev co, thiab kev ntxhov siab zuj zus.
Kev Loj thiab Tsheb Thauj Khoom Tsim Kho:
Hauv txoj kev loj, overpasses, thiab cov viaductions, thiab cov kab hlau, SM490B hlau daim hlau tau siv los siv cov kab tshuam, cov neeg tiv thaiv, thiab kev coj ua tsis taus pa. Nws qhov ruaj khov ua kom muaj zog siv sijhawm ntev txawm tias muaj huab cua huab cua sab nraum zoov thiab cov huab cua sib txawv.
Kev lag luam thiab pej xeem tsim cov qauv:
Cov hlau tau siv dav hauv cov teeb meem, chaw khaws khoom, siab -}} Cov vaj tse muaj ntau yam. Nws weldability thiab formability ua nws haum rau prefabricated txheej txheem sib xyaw, txhim kho kev ua haujlwm thiab kev nyab xeeb.
Siv Machinery thiab cov khoom siv hnyav:
SM490B feem ntau siv nyob rau hauv cranes, loaders, thiab nqa cov khoom siv thav lug thiab muaj zog tsis kam muaj zog. Nws pab kom ua haujlwm ruaj khov nyob rau hauv kev rov ua dua kev hloov chaw thiab cuam tshuam.
Forging thiab Manufacturing Txheej Txheem Ntawm SM490B Hlau Phaj
Txawm hais tias SM490B steel feem ntau yog muab cov ntaub pua uas tsis quav ntsej los ntawm cov khoom lag luam lossis cov khoom tsim kho kom zoo dua qub.
Forging / Manufacturation Txheej Txheem Txheej Txheem:
Xaiv cov khoom siv Raw:
Siab -} zoo carbon thiab qis {-}}} Alloy cov ntsiab lus tau xaiv thiab ua ntu zus los xyuas kom ntseeg tau tias muaj kev sib xyaw ua ke. Cov ntsiab lus xws li mn thiab si txhim kho lub zog thiab tawv.
Cua Sov:
Cov hlau billet yog rhuab mus rau ib qho kev tswj hwm kub tau (feem ntau 1100℃-1250 degree) kom cia deformation zoo tsis muaj kev tawg. Prelais preper kub kev tswj yog qhov tseem ceeb kom muaj cov qauv nplej.
Forging / Dov:
Lub based raited yog nias los yog dov rau qhov yuav tsum tau tuab thiab duab. Tus txheej txheem no ua kom cov qauv sib dhos sab hauv, txhim kho lub zog, kev nruj me ntsis, thiab tag nrho cov khoom siv kho tshuab sib xyaw.
Li cas / tswj txias:
Tom qab kev sib sau, cov hlau txias rau hauv cov kev tswj hwm lossis ib txwm muaj. Kauj ruam no pab tshem tawm sab hauv kev ntxhov siab thiab txhim kho cov qauv kev ruaj khov, ua kom pom kev ruaj khov cov khoom lag luam kom muaj kev ua tau zoo ib zaug thaum siv.
Kev tshuaj xyuas zaum kawg:
Tsis - Kev Tshuaj Ntsuam Xyuas (NDT), Kev Ntsuas Cov Khoom Siv Tshuaj, thiab Kev Ntsuas Cov Neeg Kho Mob Cov Cuab Yeej Siv tau ua tiav JIS G3106 Cov Qauv.
