Kev sib twtsis yog tsim los ntawm cov hlau yooj yim cam khwb cia lossis cov hlau zoo tib yam,Tab sis theej los ntawm cov txheej txheem tshwj xeeb high - Kev ua tau zoo caij nplooj hlav steel. Thaum lub sijhawm tseem ceeb ntawm lub caij nplooj ntoo hlav hlau yog hlau, nws tus nqi tseem ceeb nyob hauv nws cov qauv tshuaj muaj pes tsawg leeg thiab cov txheej txheem kev tsim khoom nyuaj. Tseem txhim kho cov khoom siv me me ntawm cov hlau los ntawm kev ntxiv cov kev sib txuam ntawm cov khoom siv roj carbon ntau, silicon, manganese, thiab chromium. Cov ntsiab lus ua haujlwm ua haujlwm ua haujlwm ua haujlwm ua ke muab cov khoom siv ib qho siab ywj pheej thiab nkees} - cov hlau hlau tsis muaj.

Lub ntsiab lus ntawm Rail clip tsim cov lus dag nyob hauv nws cov txheej txheem kev kho cua sov.Cov hlau, tsim thaum pib los ntawm kub dov, undergoes quenching thiab siab - kub kub. Quenching muab cov hlau ua kom muaj zog ua kom haum nws cov microstructive zoo li ntawm ultra {2} Lub zog zoo tshaj plaws, qhov kawg ua rau muaj qhov ruaj khov ua kom templection. Qhov no microsure paub tias tus ciav hlau tuaj yeem muab cov quab yuam sib luag ntau dua lab ntawm cov tsheb thauj khoom uas tsis muaj kev cuam tshuam yas deformure. Siv cov kab nrum cam khwb cia ntse, qhov twg sab hauv graphite flakes ua rau muaj kev ntxhov siab hauv qab, yuav ua tsis tiav qhov xav tau kev nyab xeeb ntawm kev ua kom muaj kev nyab xeeb.
Tsis tas li ntawd, kom tau wallst nrho cov chaw sab nraudCov txheej txheem feem ntau yog kub - dip galvanizing, uas tsim lub dense zense thiab cov neeg sawv cev hauv qab, yog qhov tseem ceeb tshaj nws txoj kev pabcuam lub neej.
Tus ciav hlau clips los ntawmGnee Railnruj me ntsis ua raws li cov khoom siv science thiab engineering. Peb xaiv lub caij nplooj ntoo hlav loj tshaj plaws uas ua raws li cov txheej txheem kev kho cua sov thiab ua kom muaj kev tiv thaiv kom sov thiab cov kev cuam tshuam rau cov kev cuam tshuam rau cov khoom siv hnyav, cuam tshuam, thiab cov mob corrosive.
