ISCOR Txoj Kev Tsheb Ciav Hlau Hlau Txoj Kev Tsheb Ciav Hlau Zoo Txoj Kev Tsheb Ciav Hlau Hlau
TXHEEJ TXHEEM TXOG KEV TSIM KHOOM
Raws li cov ntaub ntawv sib txawv,cov ntsia hlaumuaj peev xwm muab faib ua cov hlau hlau uas muaj cov pa roj carbon zoo li qub, cov hlau uas muaj zog tsawg, cov hlau uas tiv taus kev hnav thiab cov hlau uas tiv taus cua sov, thiab lwm yam. Cov hlau hlau uas muaj cov pa roj carbon zoo li qub yog hom uas siv ntau tshaj plaws thiab muaj cov yam ntxwv ntawm lub zog siab thiab kev hnav tsis kam zoo;
Cov hlau tsis tshua muaj zog muaj zog dua thiab tsis kam hloov pauv; cov hlau uas tiv taus hnav thiab tiv taus cua sov yog qhov tsim nyog rau cov tsheb ciav hlau ceev ceev thiab cov kab thauj khoom hnyav.
Qhov Loj ntawm Khoom
Raws li cov duab sib txawv, cov hlau tuaj yeem muab faib ua "I-puab", "yim-puab", "trough-puab", thiab lwm yam. Ntawm lawv, "I-puab" yog qhov feem ntau, nrog lub peev xwm thauj khoom muaj zog thiab yooj yim teeb tsa; "yim-puab" yog qhov tsim nyog rau cov kab nkhaus thiab muaj kev ua tau zoo ntawm kev tsav tsheb; "trough type" yog qhov tsim nyog rau cov tsheb ciav hlau hauv nroog, thiab lwm yam. Qhov twg suab nrov thiab kev co yuav tsum tau txo qis.

NTA
Nyob ntawm thaj chaw siv,txoj kev tsheb ciav hlaumuaj peev xwm muab faib ua cov tsheb ciav hlau ib txwm thiab cov tsheb ciav hlau tshwj xeeb. Cov tsheb ciav hlau ib txwm yog tsim rau cov kab tsheb ciav hlau dav dav thiab muaj cov yam ntxwv ntawm lub peev xwm thauj khoom muaj zog thiab tiv taus kev hnav zoo; cov tsheb ciav hlau tshwj xeeb yog tsim rau cov tsheb ciav hlau hauv qab cov xwm txheej tshwj xeeb, xws li thaj chaw alpine, ntug dej hiav txwv, thiab lwm yam.
DAIM NTAWV THOV
Nyob ntawm qhov ntev,hlau tsheb ciav hlautuaj yeem muab faib ua qhov ntev tus qauv thiab qhov ntev tsis tus qauv. Qhov ntev tus qauv feem ntau yog 12 meters, uas yog qhov tsim nyog rau feem ntau ntawm cov kab tsheb ciav hlau; qhov ntev tsis tus qauv tuaj yeem hloov kho raws li qhov xav tau tiag tiag. Piv txwv li, qee lub choj, qhov av thiab lwm qhov chaw tshwj xeeb xav tau cov tsheb ciav hlau luv dua lossis ntev dua.
NTIM THIAB XA KHOOM
Keeb kwm ntawm kev tsim tsheb ciav hlau hauv kuv lub tebchaws tuaj yeem taug qab rov qab mus rau xyoo pua 19th. Xyoo 1894, Tuam Tshoj thawj txoj kev tsheb ciav hlau tau dov tawm ntawm Hanyang Iron thiab Steel Works, uas feem ntau yog cov hlau nruab nrab-carbon British rail. Tom qab kev tsim tsa ntawm Lub Tebchaws Suav, cov hlau tsheb ciav hlau feem ntau yog qhib-hearth high-carbon steels P68, P71, thiab P74. Cov hlau tsheb ciav hlau tau maj mam ua tus qauv thiab tus qauv los ua 780MPa qib U74 thiab 880MPa qib U71Mn. Tom qab ntawd, 980MPa qib U76NbRE thiab U75V, 1180MPa qib U77MnCrH, thiab 1280MPa tau tsim kho tas li.
