Nruam Welded Rail Daim Ntawv Thov hauv Indian
Nruam Welded Rail (CWR) thev naus laus zis tau siv dav los ntawm Indian Railways, nrog rau cov chaw tsim hluav taws xob rail vuam nyob hauv thaj chaw tseem ceeb xws li Mumbai, Meerut, thiab Secunderabad. Hauv qab no yog cov ntsiab lus ntawm nws daim ntawv thov.
- Rail Vuam Factories
Indian Railways ua haujlwm ntau lub tsheb ciav hlau welding factories nruab nrog cov tshuab tshwj xeeb rau pob tw vuam steel ntsia mus rau qhov ntev mus txog 100 meters. Cov chaw ua haujlwm no ua kom muaj txiaj ntsig zoo ntawm CWR ntu kom tau raws li qhov xav tau ntawm cov phiaj xwm kev tsheb ciav hlau.
- Txo suab nrov
Welding steel rails mus rau qhov ntev txuas ntxiv pab txo cov suab nrov uas tsim los ntawm kev ua haujlwm tsheb ciav hlau. Kev tshem tawm ntawm qhov tsis sib xws ntawm cov ntu kev tsheb ciav hlau ua kom cov chaw taug kev zoo dua, ua rau muaj kev mus ncig ntsiag to rau cov neeg caij tsheb thiab cov neeg nyob hauv cov kab tsheb ciav hlau.
- Fishplate Joints
Txawm hais tias siv CWR, cov pob qij txha ntses tseem tau muab tso rau hauv cov kab ke taug kev. Cov pob qij txha no, feem ntau tau teeb tsa txhua 100 meters, tso cai rau kev nthuav dav ntawm cov ntsia hlau thaum lub sijhawm huab cua kub. Lawv haum rau thermal expansion thiab contraction, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb.
