Carbon caij nplooj ntoos hlav hlau tam sim no lub teb chaws thiab kev ua hauj lwm pom zoo muab hom sub sub-ob hom:
1, txias lub caij nplooj ntoos hlav xaim hlau
Ib qho yog lub cev deformation reinforced steel hlau, tseem hu ua txias lub caij nplooj ntoos hlav xaim hlau. Cov dej khov-xais hlau uas muaj hlau khov heev tsuas yog ua rau kev ua kom muaj quenching cov kev kho mob thiaj li tau txais cov qauv nplooj, thiab ua kom dej phosphating, nrog rau cov nqi ntawm cov khoom tsim, cov hlau hlau yog fibrous, nrog high tensile zog thiab elastic txwv, Kev ua kom zoo tshaj qub thiab kev pauv hloov. Txias-twv lub caij nplooj ntoos hlav xaim lub siab tshaj plaws, lub teeb ci, tsis muaj oxidation thiab decarburization defects, nkees lub neej piv yog ruaj khov, yog feem ntau siv dav caij nplooj ntoos hlav xaim.
2, roj quenching thiab tempering steel hlau
Lwm hom carbon caij nplooj ntoos hlav steel hlau yog martensitic reinforced steel hlau, tseem hu ua roj quenched thiab tempered steel hlau. Carbon steel hlau los quenching thiab tempering kho, nkag mus rau yav tom ntej txhua yam kev ua haujlwm, thaum tus qauv txheem me (φ ≤ 2.0mm), roj quenched thiab tempered hlau ntawm lub zog ntawm txoj cai tshaj li sintered kev kho ntawm txias twv hlau hlau lower The When the standard standard is bigger (φ ≥ 6.0mm) Saussure steel hlau tsis siv qhov kev txo qis loj kom tau txoj cai yuav tsum tau muaj zog, thiab roj quenched thiab tempered hlau xaim tau ua kom tiav ntau tshaj qhov txias Rub lub xaim muaj nuj nqi dua. Nyob rau hauv tib lub zog tensile, martensite reinforced steel hlau muaj ib tug siab dua tshaj li tshaj li lub deformation deust reinforced steel hlau. Lub microstructure ntawm txias twv hlau hlau yog fibrous, thiab anisotropy yog pom tseeb. Lub microstructure ntawm cov roj quenched thiab tempered hlau xaim yog homogeneous tempered martensite, yuav luag yogotropic. Nrog cov roj quenching thiab tempering steel wire anti-slack muaj nuj nqi zoo tshaj txias dua hlau xaim, kev siv cov kub (150 ~ 190 ℃) thiab tseem siab dua cov npoo txias txias (≤ 120 ℃). Hauv nruab nrab ntawm cov xyoo no, cov txheej txheem roj quenching loj heev, cov kab hlau uas muaj qhov kub hnyiab muaj ib txoj kev zoo los hloov cov xim txias twv hlau.
