Cov hlau xaimyog ib txoj hlau hlau uas rub los ntawm billet lossis hlau kub-kuav thiab siv dav hauv kev tsim kho, tsheb, kev tsim khoom thiab ntau lwm yam teb. Hlau yog lub npe hu rau nws lub zog tensile siab, thiab qhov no yog qhov tseeb tshwj xeeb rau hlau hlau. Cov txheej txheem ntawm kev rub hlau rau hauv hlau sib phim cov qauv siv lead ua ntawm cov hlau, tsim cov khoom siv uas tuaj yeem tiv taus kev ntxhov siab thiab kev ntxhov siab. Qhov no ua rau cov hlau hlau pas nrig yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov kev tsim kho tseem ceeb uas xav tau lub zog thiab kev ua haujlwm ntev, xws li kev tsim kho choj, tsev thiab lwm yam haujlwm tsim kho vaj tse.
Ntxiv rau nws lub zog, cov hlau hlau kuj muaj kev ywj pheej zoo heev. Txawm hais tias nws muaj zog, nws tuaj yeem yooj yim khoov, ntswj thiab tsim yam tsis muaj kev cuam tshuam rau nws cov qauv. Qhov kev ywj pheej no ua rau nws tsim nyog rau kev tsim cov cables, xov hlau, caij nplooj ntoos hlav thiab lwm yam khoom uas xav tau ductility yam tsis muaj kev txi lub zog. Lub peev xwm ntawm cov hlau hlau los tswj nws cov duab thiab kev ua tau zoo nyob rau hauv ntau yam mob ua rau nws yog cov khoom siv xaiv rau cov chaw tsim khoom thiab cov engineers.
Qhov ua tau ntau yam ntawmhlau xaim pas nrigtxuas ntxiv mus rau nws siv hauv kev lag luam tsheb. Hlau hlau yog ib qho tseem ceeb hauv kev tsim cov log tsheb, muab cov khoom siv txhawb nqa kom tiv taus cov xwm txheej nyuaj. Kev sib xyaw ua ke ntawm hlau hlau lub zog thiab kev ywj pheej ua kom cov log tsheb tswj tau lawv cov duab thiab kev ruaj khov thaum muab cov traction thiab kev ywj pheej tsim nyog. Tsis tas li ntawd, cov hlau hlau siv los tsim cov caij nplooj ntoos hlav ncua, cov thav duab rooj zaum, thiab lwm yam khoom siv tsheb uas xav tau kev sib npaug ntawm lub zog thiab kev ywj pheej.
Kev lag luam kev tsim kho kuj tau txais txiaj ntsig zoo los ntawm kev sivhlau hlauTxij li cov qauv pob zeb ua kom ruaj khov mus rau kev tsim cov laj kab thiab cov teeb meem ruaj khov, nws yog cov khoom siv tseem ceeb hauv kev tsim kho thiab cov haujlwm tsim kho vaj tse. Nws lub zog tensile siab ua kom cov qauv ruaj khov thiab lub neej ntev, thaum nws qhov yooj ywm tso cai rau kev teeb tsa yooj yim thiab kev hloov kho raws li cov kev xav tau tshwj xeeb ntawm cov haujlwm.
Raws li thev naus laus zis thiab kev tsim kho tshiab txuas ntxiv mus, cov hlau xaim yuav tsis muaj qhov tsis ntseeg tias yuav txuas ntxiv mus ua cov khoom siv tseem ceeb thiab yog qhov tseem ceeb hauv kev lag luam.
