Thaum xaiv qhov tsim nyog steel rail, xav txog qhov hnyav ntawm cov loads nws yuav dais. Standard rails feem ntau yog siv nyob rau hauv cov pa rail systems, thaum hnyav rails yog nyiam rau cov kab uas muaj kev tsheb loj thiab loads. Crane rails, ntawm qhov tod tes, yog tsim rau cov nyiaj siv ua haujlwm thiab gantry cranes, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb nyob rau hauv cov khoom hnyav. Nws tseem yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas cov rail profile, vim nws cuam tshuam rau kev ua haujlwm ntawm kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov hlau rail.
Txoj kev tsheb ciav hlau yog dab tsi?
Txoj kev tsheb ciav hlau feem ntau yog ua los ntawm cov qib siab -zoo, kub- dov steel alloys, tshwj xeeb nruab nrab- carbon steels nrog cov ntsiab lus xws li manganese, silicon, thiab qee zaum chromium, vanadium, lossis niobium, los muab lub zog hnyav, hardness, thiab hnav tsis kam yuav tsum tau tiv taus hnyav, ceev tsheb ciav hlau.
