Kev sib tw khi phaj tseem yog hu ua kev tsheb ciav hlau phaj lossis tsuas yog lub ntsiab tiv thaiv hauv kev tsheb ciav hlau los yog taug qab txhawb nqa cov kab ke.
Kev sib tw khi tuaj yeem faib nyob ntawm ib qho lossis ib qho chaw tsim kho xwb pwg, gnee Rail tuaj yeem muab ntau tus Ribbed khi daim hlau.Ib lub xub pwg khi daim hlau \\ ob chav lub xub pwg lub hau paib phaj yog muaj arema nuv ntxaib khi phajlwm yam.
Gnee Rail muaj cov kws tshaj lij kev txawj ntse thiab paub tab Technology los xyuas kom muaj qhov zoo ntawm cov phiaj pw tsaug zog. Feem ntau, dov sleeper daim hlau yog tsim tau sivQ235 Cov Hlau.
Q235 Cov Hlau, tseem hu ua A3 carbon steel, derives nws lub npe los ntawm nws cov txiaj ntsig lub zog: "Q" sawv ntsug kom txwv, thiab "235" qhia tau tus nqi nce siab txog 235 MPA. Nrog cov ntsiab lus carbon ua ke, nws muaj kev sib xyaw ua ke ntawm lub zog, muaj zog, thiab weldability. Vim nws lub siab - rounded cov khoom siv neeg kho tshuab, Q235 Cov Hlau Hlau yog dav siv nyob rau hauv kev tsheb nqaj hlau ceev ceev.
QT400-18 Carbon Steelfeem ntau siv rauNruag Lub Plawv Zawm, nrog nrum ua cov txheej txheem tsim khoom ntau tshaj plaws rau cov khoom siv no. QT400-18 yog tsim ntawm cov hlau, carbon, thiab silicon. Nws ua rau pom kev zoo weldability, machinity, thiab condityity, nrog rau kev cuam tshuam loj ntawm chav sov. Cov yam ntxwv no ua rau nws haum rau Casting Sleeter daim hlau thiab lwm yam kev tsheb nqaj hlau.
Hlau dawbfeem ntau ua haujlwm rauforged sleeper daim hlauCov. Nrog rau cov ntsiab lus carbon ntawm kwv yees li 2.5%, cov hlau dawb yog qhov nyuaj heev thiab ntsej muag daj ua rau nws cov ntsiab lus carbide). Forging yog lwm txoj hauv kev rau kev tsim cov phiaj pw tsaug zog tsaug zog.
Q345 Cov HlauKuj tseem siv rau kev zam cov tsheb ciav hlau pw tsaug zog. Cov khoom siv no muaj cov khoom siv tshuab ua kom zoo nkauj, zoo kub thiab txias ua haujlwm, thiab corrosion tsis kam. Cov cwj pwm no ua Q345 carbon hlau zoo tagnrho rau kev tsim khoom siab- thauj welded Cheebtsam.
