Txoj kev tsim cov pa roj carbon steel hlau nrog kev ua haujlwm zoo heev
High carbon steel hlau feem ntau yog hais txog xaim nrog cov ntsiab lus carbon ntau dua lossis sib npaug li 0.70%. Nws yog cov khoom siv tseem ceeb rau kev tsim steel hlau ropes, choj hlau, log tsheb, cov xov hlau caij nplooj ntoos hlav, cov xov hlau prestressed thiab lwm yam khoom. Nws muaj ntau yam zoo xws li lub zog siab thiab zoo hnav tsis kam. Cov txheej txheem kev ua haujlwm ntawm cov pa roj carbon steel hlau yog feem ntau: Them tawm → Nres rau cov hlau tsis sib haum → Cov khoom siv plhaub → Siv polishing tshuab → dej kub ntxuav → Boron txheej → ziab → Linear hlau kos duab tshuab → Tension ncej → Trunk - hom hlau noj . Ntawm lawv, cov txheej txheem nyuaj tshaj plaws rau cov hlau zoo yog cov txheej txheem kev kos duab, tab sis qhov uas twb muaj lawm siab carbon steel hlau kos duab compression tus nqi feem ntau tsawg dua los yog sib npaug li 85%.
